Preface
ZF-AS Tronic and ZF-AS Tronic mid are automatic transmission systems.
A ZF-AS Tronic application contains the following stages:
To avoid
• Writing of customer specification for the transmission system by vehicle manufacturer and ZF,
• Damage or failure of the transmission and vehicle,
• Documentation by ZF,
• Functional limitations for the transmission system,
• Initial installation,
• Limitations in terms of operating quality,
• First installation check and initial setup by ZF staff,
the details on the function, installation, and initial start-up of the transmission system MUST be noted.
• Approval on the basis of the customer specification and parts list.
This technical manual serves as a technical guide for the ZF-AS Tronic system for both vehicle and vehicle body manufacturers as well as ZF staff.
NOTE If the specifications noted in this technical manual are not observed or if parts which are not approved by ZF or are not genuine ZF parts are used, this may result in damage as well as functional limitations for which ZF shall assume no responsibility.
This manual describes the standard ZF application. Customer-specific deviations must be agreed on in writing with ZF.
If you have any questions, suggestions or possible improvements, please contact your Technical Sales department contact directly.

1.1
General The driver has the opportunity to drive the vehicle in both semi-automatic mode and fully automatic mode. When in semi-automatic mode, manual shifting is simplified through the use of a range selector.
The ZF-AS Tronic transmission system is a combination of an electronically-pneumatically shifted constant mesh gearbox and an automated dry clutch. An electronic engine control unit and CAN communication must be in place before the ZF-AS Tronic transmission system can be used.
When in fully automatic mode, gears are selected and shifted by the electronic transmission control unit, although the driver can intervene if so desired. All system functions needed, e.g. Neutral, gear change, clutch overload, and diagnosis information are shown on the display.
The automated clutch (no clutch pedal) renders clutch operation by the driver unnecessary. The actual shift process is undertaken by the electronic transmission control unit.

Transmission System and its Components
2.1
System Design components and instead uses the vehicle’s systems such as engine electronics with accelerator pedal (6) and brake pedal (7), electronic brake system with wheel speed sensors etc.
The transmission system consists of the transmission (1) and the components needed to automate the system. The transmission actuator (2) and clutch actuator (3) components are integrated in the transmission. The peripheral components, i.e. the range selector (4), rotary switch (9), display (5), and ZF extension module (8) should also be installed in the vehicle.
The ZF-AS Tronic is integrated in the overall vehicle system by networking the vehicle electronics by means of a CAN bus. The reciprocal system dependencies this produces must be investigated as part of a vehicle integration FMEA.
When integrated in the vehicle system, the ZF-AS Tronic no longer needs its own peripheral

Transmission and Shift System
2.2.1 Description of Transmission The ZF-AS Tronic family covers the following transmission types: • ZF-AS Tronic mid (product families 1+2) • ZF-AS Tronic (product families 3+4)
– The precise assignment of all transmissions to product families and the max. permissible torques can be found in the Annex (5.1 + 5.2).
All transmissions of the ZF-AS Tronic family consist of a four-speed section in the 16-speed version or a three-speed section in the 12-speed version and a splitter group (GV) and rear-mounted range change group (GP) in a planetary design. The 4(3)-speed transmission section has constant mesh engagement. Speed-matching (synchronization) is performed by the engine control unit and the transmission brake. The splitter group and range change group have synchromesh. The transmissions of product families 1+2 have one countershaft. The transmissions of product families 3+4 have two countershafts. This compact design (with reduced weight) ensures a good distribution of torque, lower gear loading levels, and therefore greater efficiency in this performance class.

Transmission Components
2.3.1 Transmission Actuator All functions needed for open loop/closed loop transmission control can be found in the transmission actuator. It has a mechanical, electrical, and pneumatic interface and is integrated in the transmission housing in a space saving manner. •
The integrated transmission electronics contain all functions needed for open loop / closed loop transmission and clutch control.
•
The electropneumatic valves control the shift cylinder and transmission brake.
•
The pneumatic shift cylinders actuate the mechanical shift elements in the transmission.
Integrated transmission electronics
•
The sensors record - the current position of all shift cylinders - the transmission input speed - the transmission temperature - the level of air pressure available.
•
The vehicle end connector is the electrical interface to the vehicle CAN system network, the interface to the display, range selector, power supply, diagnosis units, etc.
•
The transmission electronics are integrated in the housing cover. The diagram (Fig. 2.5, on right) shows the transmission actuator with open housing cover.
•
Pneumatic connections are provided by the corresponding connection channels – electric connections by short connection cables.

2.3.2 Clutch Actuator
024474
Fig. 2.6
The clutch actuator is flange-mounted on the integrated clutch bell housing of the transmission. The clutch is actuated by the clutch actuator, which in turn is actuated by the electronics in the transmission actuator. Clutch actuator and transmission actuator are connected (electrically) by the wiring harness integrated in the clutch actuator and the relevant transmission actuator connector (transmission end connector). In addition to the pneumatic actuation piston responsible for the clutch release, the following components are integrated in the clutch actuator: Two cyclic valves are used each for opening and closing the clutch, whereby both valves have rearmounted orifices of different diameters.
The position of the pneumatic piston and therefore the clutch is recorded by a travel sensor. An electronics module in the clutch actuator provides the sensor signal for the transmission control unit. The clutch can be engaged in a very finely metered manner for sensitive setting off and maneuvering. For very quick clutch actuations, if necessary, the opening and closing times and/or cycle frequencies can be varied to ensure adjustment speeds appropriate for the situation. During every starting procedure, the present clutch initial contact point is learnt in and stored in the transmission actuator for use at a later date (clutch control). This learning in procedure ensures that up to date information about the wear status of the clutch lining is available to the control software at all times. The driver is warned in good time before the clutch is fully worn.

ZF-AS Tronic As a further range selector variant, the new ZF selector lever with integrated E-module can be used for the ZF-AS Tronic system. This range selector contains the electronics (E-module) needed for recording, transfer, and activation:
Transmission System and its Components Input: “low active” Vin_low < 3,0 V, Impedance: > 1 kΩ (pull-up onVP) Output: “high active”
Selector lever (cpl.) Part number: 6006 039 005 Drawing number: 6006 639 002 Rotary switch (cpl.) Part number: 6006 199 080 Drawing number: 6006 629 032 The range selector is the control element for: • Selecting the driving range, • Selecting the gear, • Activating / Deactivating automatic mode, • Selecting the search function. The positions of the lever-type range selector are recorded using a sensor matrix and converted into CAN signals by the electronics in the range selector. In addition to recording the driver’s request, an input and an output signal can also be connected to the range selector. The definition of the components connected to the input or output as well as their wiring should if necessary be established in agreement with ZF. If the range selector output is used to activate a component, then the ground / earth connection of this component MUST be routed back to the range selector. The definitions of the corresponding implementations must be agreed upon with ZF.
Vin_high > 8,0 V, Impedance: > 150 kΩ (pull-down on VM) The following limit values are to be observed for the wiring of the digital outputs: Total current (sum of all ADs): 730 mA Maximum current per output (AD): 600 mA Maximum extinction energy: 15 mJ
A valid inductive-load reference value may be: Lmanufacturer = Specified inductance value of manufacturer or measured value [mH] IL = Rated current [A] RL = Rated resistance [Ω] The approximate inductive-load limit value referred to the maximally permitted extinction energy can be determined as follows: Lmanufacturer <

2.4.1.2 ZF Extension Module The extension module serves to extend the I/O scope of a transmission control unit. The module and transmission control unit communicate through a CAN interface. Outputs can be served by the transmission control unit (TCU) via the CAN interface. Consumers which are connected to one of the ground/earth switching outputs can, in the event of an error, be deactivated by the central deactivation channel (two pins). Input signals are recorded and are then made available for the TCU via CAN communication. These are e.g. PTO request, PTO confirmation signal, or the door signal. Outputs, whose software functions can be assigned, are also activated, e.g. activate Neutral in transmission or PTO1/2. If an earth/ground-switching output of the extension module is used to activate a component (e. g. PTO), the component must be attributed to the VPS output. The definitions of the corresponding implementations must be agreed upon with ZF. Part number: Drawing number:

3.1
Basic Function – Detailed descriptions of the signals can if necessary be found in signal specification ZF no. 1328 761 005.
The basic function ensures that the ZF-AS Tronic and the pneumatically activated clutch are operated in the relevant operating / drive situations. Amongst other things, this includes selecting gear, setting off, maneuvering, and gear shifting.
In the standard application of the ZF-AS Tronic transmission system, data is exchanged via another CAN interface to ZF components (such as e.g. ZF selector lever, extension module, range selector module) for recording range selector information and also for activating PTOs. This CAN bus connection is operated separately from the vehicle CAN.
The basic function includes the recording of all signals needed for the function. These are signals from sensors, such as travel, speed as well as pressure and temperature sensors, which are fitted on and in the transmission. Further function-relevant information is exchanged between the vehicle's electronic systems and the transmission control unit (TCU) via the vehicle CAN (Control Area Network).

A good diagnosis concept is needed to handle the large number of signals makes. Sections 3.4 and 3.5. contain descriptions of this.

ZF-AS Tronic
Function Description
3.1.1 Shift Engagement Characteristics / Ignition On
3.1.2
Gear Selection With Vehicle Stationary
In general during standstill shifts, the transmission control unit specifies zero filling, i.e. load reduction to the engine control unit. A distinction is made between three different shifts.
When the ignition is switched on, the sensor and control elements, valves, actuator cylinders etc. are checked for errors (e.g. short circuit, interrupt, main transmission in Neutral, plausibility in accordance with specification). During this ignition on and/or check phase, the transmission and clutch-related sensor values are acquired by the system.
3.1.2.1 Shifting from Neutral When shifting from Neutral, the clutch is opened and the splitter group, range change group, and gate are shifted in parallel into their nominal positions. The transmission brake is used to reduce the transmission input speed and then the main transmission activated.
This “learn-in” procedure can only start if there are no errors on the clutch actuator and Neutral is successfully learnt in via the transmission sensors. During the learning in procedure, the main points of the clutch actuator’s adjustment range must be determined and saved. The clutch actuator needs these points (once determined) during travel, depending on the relevant drive situation. The absolute position of these points depends on the stretch and tolerances of the mechanics of the entire clutch activation path as well as depending on the present degree of clutch wear. The clutch learn in procedure can be used to compensate for any possible clutch wear.
3.1.2.2 Shifting From One Gear to Another If the setting off gear is manually corrected (to select a higher or lower gear) when the vehicle is at a standstill, this is a shift from one gear to another. In this instance, if the clutch is already open, the transmission input and output speeds are zero so that the new gear requested can be selected directly.
3.1.2.3 Shifting to Neutral If the driver selects Neutral from the setting off gear, this request is implemented immediately by shifting from one gear to the next and the clutch then closed.

As regards the 16- and 12-speed transmissions, always engage the slower R gear for rearward driving. No automatic gearchange takes place. The fast R gear must be manually selected on the range selector.
The starting gear for forward driving can be corrected by the driver. On the basis of the starting gear selected by the (automatic) shifting strategy, and depending on the application, free gear selection is possible either upwards or downwards, including the maximum starting gear. Depending on the application, the maximum starting gear for the 12-speed

Phase 3

ZF-AS Tronic
Function Description If thermal overloading arises during the second phase, the driver is informed of this via the display. The nominal engine speed is continuously reduced at the same time. This is achieved by successively closing the clutch. The nominal engine speed can be reduced until the engine stalls.
Through actuation of the accelerator pedal in various situations (loaded/empty, level road/uphill/downhill), comfortable starting without clutch damage is possible. If the vehicle rolls in the opposite direction of travel, the engine does not stall when setting off. The setting off procedure is aborted if the load is reduced or the brake pedal is actuated.
If the clutch travel sensor fails, a changeover is made to time-controlled closing / opening of the clutch.
The setting off procedure basically consists of four phases: In the first phase, the clutch’s idle stroke is surmounted. This is the range in which the clutch does not transfer torque. The position up to where the clutch is closed is applicable. After every clutch learning in procedure, the applied position is entrained in accordance with the modified clutch travel. Overriding the idle stroke serves to pass through the range in which the clutch transfers no torque as quickly as possible. Clutch closed loop control then starts in the second phase. This varies the clutch position and therefore the clutch torque to set a nominal engine speed. The nominal engine speed is determined using characteristics which depend on the gear selected, transmission input speed, and engine idling speed. If the speed falls below an applicable difference in speed between engine and transmission input speed (typically 50 rpm), the system switches into the third phase. In this phase, the clutch is closed in a controlled manner, the speed of which depends on the accelerator position. The third phase is exited once the clutch is around 90 % closed. The fourth phase starts when the clutch is closed. Residual venting is then used to fully vent the pressure chamber of the clutch actuator. During the setting off procedure, the engine torque is increased via ramp from an initial value to the torque level requested by the driver. Engine torque intervention makes comfortable setting off possible.

3.1.5 Maneuvering closed position and the target engine speed increases. Sliding friction is produced on the friction interfaces as a result of the partially closed clutch. The transfer torque on the clutch is set by the control unit so that drive resistance is surmounted. The vehicle can thereby be moved slowly and sensitively forwards or backwards using the accelerator.
If the driver actuates the accelerator within a defined range, appropriate clutch travel is also set via the clutch actuator. Here, the electronic transmission control unit (TCU) governs the engine speed bringing it to the level required for maneuvering operations. As the accelerator is increasingly actuated, the clutch is moved further towards the

Function Description There is no automatic gear change during maneuvering. A gear change must be requested manually by the driver using the range selector.
The clutch travel depends not only on the accelerator position but also on the maneuvering gear selected and shifted using the range selector. If the automatically selected starting gear for “maneuvering via accelerator pedal position” is not a practicable maneuvering gear, the maneuvering gear will have to be selected manually on the range selector.
Depending on vehicle features (maneuvering via accelerator pedal position or maneuvering via maneuvering switch), the maneuvering mode will be exited as soon as the accelerator pedal is no longer within the range defined for maneuvering or as soon as the driver selects “D” on the range selector.

3.1.6.1 Engine Protection Function In the “automatic” drive program, an automatic upshift may occur to protect the engine from overspeed when engine speeds exceed a defined speed threshold (x% above nominal engine speed). Automatic upshifts do not occur in manual mode.
If the warnings are not observed, active protective measures are automatically initiated. If the setting off gear selected is greater than 1st gear, then the clutch engagement speed increases as the friction energy increases so that as clutch loading increases, the period of loading (slip time) is reduced sufficiently. Depending on the clutch load calculated, a shift is also automatically made back into a lower setting off gear.
NOTE This function must be discussed by the customer and ZF.
3.1.6.2 Clutch Overload Protection (also refer to Section 4.8.1.3) In order to prevent the clutch from being damaged as a result of excessively long friction processes, the present clutch load is continuously calculated from the clutch torque, differential speed on clutch and the slip time. Taking the previous friction processes into consideration, checks are undertaken to determine whether the load limit value has been exceeded.
When in maneuvering mode and when a defined threshold value is reached, a shift is made from maneuvering mode into setting off mode. In other words, the clutch automatically begins to close to encourage the driver to set off. Once cooled down to below the threshold valve, maneuvering mode is again permitted.

ZF-AS Tronic
Function Description NOTE The transmission control unit (TCU) only checks transmission-internal conditions for the acceptance of PTO operation. The vehicle manufacturer is responsible for the safety-related requirements of PTO operation.
3.1.7 Control of PTOs With the transmissions AS Tronic and AS Tronic mid, independent software configuration (stationary or stationary/mobile) and control of 2 clutch-dependent PTOs is possible. PTO engagement is only possible during vehicle standstill and if the main transmission is engaged in neutral position and the accelerator pedal is not actuated. Depending on the individual configuration, it may or may not be possible to engage a starting gear accepted for PTO operation once power transmission to the PTO is established.
3.1.7.1 PTO Activation PTO requests will only be accepted as long as no error on the transmission end is active which prevents PTO operation.
If a stationary PTO operates it will not be possible to engage a gear, no matter whether another stationary/mobile PTO is installed or operating.
PTO requests are activated through actuation of the PTO switch. The PTO selected must be off at that point in time.
If only stationary/mobile PTOs are operating, a starting gear accepted for PTO operation can be engaged and the vehicle can be moved. Gear engagement and gearchanges will only be possible during vehicle standstill.
Only the conditions “ON” or “OFF” may be present on any other PTO. If these conditions are fulfilled, the engagement process will be initiated. While the PTO is being engaged, the EDC will receive the injection rate specification % (= load reduction) from the TCU.
Product families 1 + 2: PTOs can be operated via both constants of the splitter unit (see power-flow diagram, Section 2.2). Which of the two constants is active in neutral position of the transmission depends on the software. As regards mobile PTOs, all starting gears and all rear gears are possible. Product families 3 + 4: PTOs may only be operated via the constant K1 (see power-flow diagram / Section 2.2). The slow splitter ratio is thus always engaged on direct-drive transmissions while the fast splitter ratio is always engaged on overdrive transmissions. As regards stationary/mobile PTOs, the gears R1, 1, 3, 5 and 7 are possible (gear 7 only in the 16-speed version) in the direct-drive version while the gears R2, 2, 4 and 6 are possible in the overdrive version (gear 6 only in the 16-speed version).
1328 765 101 - 2007-10
The engagement process is as follows: 1. “Vehicle standstill”, “main transmission in neutral”, and “accelerator pedal not actuated” are the conditions checked. 2. If the ratio on the splitter unit is not as specified for stationary PTO operation (K1 or KII), this will now be set. 3. The clutch is opened and the transmission brake will bring the countershaft(s) to a standstill. 4. When the countershaft(s) is/are at a standstill, the output of the TCU will be activated for mechanical engagement of the PTO. 5. At the same time, the clutch starts to close according to a process particularly specified for PTO operation.

Function Description
6. Once the clutch is closed, the EDC injection rate will be released again by the TCU.
3.1.8 Ignition Off If the ignition is switched off, or the voltage switched via the ignition key falls (terminal 15) below a defined threshold value, a check is undertaken to determine whether the transmission is in Neutral and whether the clutch is closed. If this is not the case, the transmission undertakes an enforced shift to Neutral and the clutch is closed.
7. As soon as the PTO is engaged, a PTO indication will appear on the display.
3.1.7.2 PTO Deactivation PTO deactivation is possible in all operating conditions (driving/standstill; neutral/gear engaged). The deactivation process is as follows: 1. The deactivation command causes the output of the TCU to the PTO to be switched off. 2. At the same time, load reduction in the EDC takes place and the clutch is opened. 3. As soon as the PTO feedback signal is reset, the clutch will be closed again and load reduction in the EDC will be stopped. CAUTION Deactivation of a stationary/mobile PTO during driving operation and with a gear engaged is not permitted as in such a case the connection to the PTO is not load-free. If the PTO is nevertheless deactivated, this may result in deactivation malfunctions and the PTO may be damaged. Ignition OFF (terminal 15) during PTO operation will result in automatic deactivation of the PTO.
1328 765 101 - 2007-10
The clutch is opened for the shift to Neutral. The clutch then closes at a defined speed. If while at a standstill the transmission cannot be shifted to Neutral, the clutch remains open. The driver is informed acoustically of this malfunction. Once a defined delay period has passed, the battery voltage (terminal 30) of the electronic control unit (TCU) is disconnected via the disengagement relay. The TCU is only switched off when the vehicle is at a standstill. Special scenario: If the ignition is switched off during travel, a shift to Neutral is not undertaken. The gear selected remains selected, the clutch remains closed. Only once the speed falls below a defined threshold speed value does the clutch open and the transmission shift to Neutral (enforced neutral switch). During the ignition off phase, error memory data and driving mode information is saved from the volatile memory area (RAM) into the non-volatile memory area (EEPROM). It is therefore important to ensure that the permanent positive supply (terminal 30) is not switched off at the same time as the switched positive supply but remains on for a defined period (refer to Section 4.4.2.2.).

ZF-AS Tronic 3.2
Function Description
Automatic Drive Program
When the ZF-AS Tronic automatic drive program is installed, only accelerator and brake (service brake and 3rd brake) actuation is needed to move the vehicle. The transmission is fully automatically shifted by the transmission control unit (TCU). With the automatic drive program, customer benefits come to the fore. A reduction in fuel consumption when compared with the average driver in long haulage transport and frequency of shifting together with optimum gear selection are some of the key features of this function. The program can also be adapted to different vehicles and engines.
Other
ABS/DTC
Subsequent changes to the driveline ratio, not approved by ZF, may impact negatively on driving characteristics, especially on the vehicle’s automatic drive program. The existing vehicle CAN signals are used to network EDC (Electronic Diesel Control), ABS (Antilock Braking System), ASC (Anti-Slip Control), Intarder, and transmission. It is therefore very easy to determine the necessary driving modes. – Detailed descriptions of the signals can if necessary be found in signal specification ZF no. 1328 761 005.

Function Description
3.2.1 Activating Automatic Drive Program
3.2.3 Automatic Gear Change
The automatic drive program is activated by switching on the electrical system (ignition on), starting the engine and selecting the forwards driving range. Once the parking brake has been released and the accelerator depressed, the vehicle moves, gear shifts are undertaken fully automatically.
An operating mode control unit controls (closed loop) the transitions between various operating modes. This control unit detects driveline traction mode or coasting mode from a large number of external and internal signals. Different processes are selected within traction and coasting mode depending on kick-down, with or without engine braking Intarder operations or cruise control operations. Furthermore, the operating mode control unit decides whether manual intervention is influencing the automatic drive strategy or whether a standstill shift is present with the vehicle virtually at a standstill.
During travel, the range selector can be used to switch between the manual and automatic drive programs at any time. – For more information, refer to Section 2.4 (peripheral components/range selector).
Numerous calculations, parameters and characteristics curve evaluations, and interpolations are needed for the different operating modes. Vehicle status parameters, such as present vehicle acceleration and the present traction or coasting torque are calculated in these help functions. The drive resistance and the mass calculation are key influencing parameters for determining the shift point. Other status parameters, such as speed and the acceleration of the transmission shafts and an estimate of the vehicle mass when setting off, are used for a harmonic drive strategy.
3.2.2 Automatic Selection of Setting Off Gear When the automatic drive program is activated, the setting off gear is calculated (fully automatically) in accordance with the setting off conditions (incline, loading, etc.) and can if necessary be corrected by the driver. If the driver believes that the setting off gear, as shown in the display, is too high, then the setting off gear can be corrected (reduced) using the den range selector. – Also refer to Section 2.4, Range Selector Functions. Upward correction for protection of the clutch is only possible up to a maximally defined starting gear (depending on the application, this may include the 5th gear of the 12-speed transmission and the 7th gear of the 16-speed transmission). Even once the ignition has been switched off and the vehicle started again, a setting off gear is automatically selected.

Function Description If this shift speed is above the maximum shift speed area, the change in ratio and/or speed must be recalculated. The limit points in the upper speed range result from the accelerator position and acceleration of the transmission input speed. The ratio step is therefore determined via the shift speed calculation.
The figure (below) shows a simple upshift under traction in engine performance characteristics by way of example. A target speed range in which the engine speed is to fall after the shift process is defined in these characteristics. The target speed is determined on the basis of the current accelerator pedal position and a road-resistance-dependent correction, here a speed increase. The final shift speed results from the change in speed brought about by the relevant ratio step and a supplementary value for increased drive resistance.

ZF-AS Tronic
Function Description
3.2.4 Deactivating Automatic Drive Program The driver can use the range selector to end automatic mode at any time and make manual interventions in the automatic drive program. The driver is able to retain the present gear or undertake manual upshifts or downshifts. If downshifting would lead to overrevving of the engine, the gearshift will be prevented. If the gear is manually retained and the vehicle accelerated, this can result in overrevving of the engine. The engine protection function described under 3.1.6.1 is not active in the manual driving mode. If an error occurs in the transmission system or in the exchange of signals with other systems, the automatic program may be deactivated depending on the error found. This is, for example, the case if the mass calculation can no longer be undertaken because an important relevant signal is not longer transferred on the CAN bus or if this error is incorrect. In the standard application, the driver is informed of restricted system functions by a display. – For more information, refer to Section 2.4.3, Displays. NOTE When operated manually using the range selector, fuel consumption may if necessary increase depending on driver’s manual gear selection. The automatic setting off gear selection even also retained in manual operations.

ZF-AS Tronic 3.3
Function Description The following were identified as safety-related malfunctions as defined in VDI/ VDE 3542 Page 1 in the risk analysis:
ZF-AS Tronic Malfunction Concept
3.3.1 Principles The ZF-AS Tronic is an automatic system, which unlike conventional driveline components, takes on all or some of the processes controlled by the driver. In some instances, responsibility for these processes passes from the driver to the system. In order to fully satisfy this level of responsibility, the ZF-AS Tronic transmission system has been subjected to a state-ofthe-art technical system error analysis.
3.3.2 System Analyses Undertaken • • • • •
Risk analysis as defined in DIN V 19250 Error tree analysis System FMEA Design FMEA Integration FMEA (part of the application)
Previously defined vehicle responses (commonly referred to as TOP EVENTS) which take various driving modes into consideration formed the starting point for analyzing conceivable malfunctions resulting from faults or errors occurring during correct system usage. The risk analysis as defined in DIN V 19250 resulted in requirement class 4 for the ZF-AS Tronic transmission system under unfavorable circumstances. The following were defined as safe nominal statuses to be aimed for in the event of an error, depending on the driving mode: • “driveline closed” during travel • “driveline open” with vehicle at a standstill The electronic system must have at least partial function for these nominal statuses to be set. If this is no longer the case, the system stabilizes in the present operating mode (failsafe mode).
1328 765 101 - 2007-10
• Automatic setting off • Setting off in opposite direction of travel • Blocked driveline during travel Errors which does not result in the aforementioned vehicle characteristics, affect the correct function of the ZF-AS Tronic and therefore vehicle reliability and availability. The system responses to simple errors are described in a malfunction specification written specifically for the relevant application. Since the vehicle manufacturer is responsible for the interaction of all systems integrated in the vehicle (also in the event of error), the error responses of the ZF-AS Tronic are discussed and agreed upon with the manufacturer as part of a vehicle integrations FMEA. During this process, vehicle-related errors which can act on the ZF-AS Tronic are included in the analysis. During development of the system, up-to-date quality assurance methods and tools have been and are being applied in accordance with state-of-the art technology. The function and service life of the mechanical and pneumatic components are designed accordingly and investigated through the use of tests. System checks are carried out before and during operations so that redundancies and error protection systems are available if required. The avoidance of safety-related malfunction is reliably reached in individual instances. Attempts are made to achieve maximum possible vehicle availability for these individual instances when defining failure responses. Vehicle availability is not usually provided in instances of accidental multiple failure which cannot be systematically covered by the system. In such instances, the system is switched into the aforementioned nominal status. If it is no longer technically possible for the nominal status to be set, the last system status is retained.

3.3.3 Clutch Actuator Concept
3.3.4 Transmission Control Unit Concept
The clutch actuator and corresponding software functions are designed so that individual errors do not result in undesirable responses. The redundant valve system, travel measurement and pressure relief valve enable a defined nominal status to be retained or set.
The transmission control unit is designed so that at least two valves always have to be switched to trigger a shift (central air and shift valve). The position of the shift cylinder in the transmission actuator is permanently monitored by a travel measuring system. The design of the transmission control unit puts this in a position where it is able to prevent undesirable shift processes in the event of individual errors.
One conceivable exceptional situation: the clutch is closed, the nominal status is “open driveline” and the air supply or voltage supply is interrupted. In this instance, the driver has to shut down or stall the engine.

ZF-AS Tronic
Function Description
3.3.5 Interface Concept Great importance (in terms of security and availability) is assigned to the interfaces between ZF-AS Tronic and vehicle. In the event of errors / faults, error responses and protection measures in the ZF-AS Tronic result in the nominal status being retained and/or the nominal status being set. One precondition for this is that vehicle malfunctions which affect the transmission system must be clearly recognizable. In order to check and ensure this principle, a “vehicle integration FMEA” (refer to Section 3.3.2 “System analyses carried out”) is created with the vehicle manufacturers and corresponding measures initiated if necessary.
3.3.6 Driving Modes Investigated In addition to the safety-related malfunctions already discussed, the following possible vehicle malfunctions were analyzed and taken into consideration: • Vehicle not setting off (gear already shifted). • Driveline interrupted during travel. • Acceleration not OK. • Vehicle rolling away (exclusion: Conscious operating error). • Vehicle cannot stop. • Unintended gear selection or gear selected with driver’s request for Neutral. • Vehicle becoming stranded.

Error Responses
Unrestricted operation available
If the ZF-AS Tronic detects system faults or errors, the system responds by providing substitute functions. These are described in what are commonly referred to as malfunction specifications. The errors themselves are sub-divided into error classes 1 to 3 and entered into the ZF-AS Tronic error memory once the ignition is switched off. The errors are shown on the display as agreed with the OEM.
• No error display. • Entry in error memory. • Possibly reduced driving comfort. • Error can be rectified during next visit to workshop.
The error presently in place is usually deleted and the resultant error response cancelled once the error is no longer in place or after “vehicle stop” and “ignition off ” (reset, transmission electronic deenergized). The error numbers can be called up via the range selector, refer to Section 3. 5 Diagnosis.

Diagnosis
3.5.3 Off-Board Diagnosis ZF can provide the OEM with the following diagnosis tools for troubleshooting on the ZF-AS Tronic in the workshop:
3.5.1 Error Memory If the ZF-AS Tronic system has detected an error, an error response and/or substitute function is activated and the error saved in the error memory (RAM). During the TCU run-down (after “ignition off ”), the error memory contents are copied into the nonvolatile memory (EEPROM).
Testman pro, ZF diagnosis system for PC applications incl. ZF diagnosis adapter DPA 05 and connection cable with ISO and/or SAE connection; – For description, refer to type sheet for ZF-Testman pro.
When the error first arises, not only the error number but various ambient conditions, such as speeds, present function status, gear, operating hours, etc. can also be saved. After this, only the frequency at which the error arises is counted.
All the necessary, transmission-specific data for a rapid and comprehensive diagnosis can be called up using the ZF Testman pro diagnosis system. The “diagnosis” function includes:
Up to 10 different errors can be saved in the error memory. If the error memory is full, non-active errors are overwritten. If an error no longer occurs after a defined number of ignition ON/OFF operations(TCU resets), the error will be erased.
• Reading present error; • Reading error memory; • Deleting error memory; • Reading identification block. The “Test inputs and outputs” function includes:
3.5.2 On-Board Diagnosis (When Using the ZF Selector Lever)
• System test when at standstill; • System test during travel;
If an error occurs, the error number can be called up on the display in the vehicle. Further vehicle operations are not permitted in the instance of serious system errors (“STOP” and “wrench” symbol). In order to show the number of the active errors on the display, the rotary switch must be turned to the “N” position and the control lever must be pressed in « + » direction. By simultaneously actuating the service brake, the existing errors which are not active are shown on the display.
• Test device (displays all digital inputs and outputs); • Displaying digital and analog parameters e.g. speeds, current strengths, and voltage levels. When undertaking specific troubleshooting, this device allows staff trained by ZF to rapidly find the error in the transmission system. Once the error has been detected, the diagnosis system proposes remedial measures. Communication occurs in the form of a serial interface. Each screen page can be printed out or saved for error documentation. The diagnosis software is available in all major languages.

4.1.4 Clutch Bell Housing
4.1.5 Clutch
The ZF-AS Tronic has an integrated clutch bell housing. Transmissions of product families 1+2 can be supplied with SAE1 or SAE2 engine connections, transmissions of product families 3+4 can only be supplied with a SAE 1 engine connection (for connection dimensions, refer to installation drawing).
The clutch, as a link between the engine and ZF-AS Tronic transmission system has to satisfy the following functions: • To ensure gear shifts and setting off processes in conjunction with the ZF-AS Tronic transmission control unit in all driving situations. • To reduce vibrations in the driveline.
Fastening to flywheel housing
• To ensure a high number of shifts with a long service life.
• Use screws of a high strength class (8.8). • Calculation in accordance with VDI 2230.
Only torsion-dampened clutches and pulled clutches approved by ZF for the relevant enginetransmission combination may be used for this purpose. The clutch is subject to stringent requirements relating to clutch torque transfer characteristics and detection of release force to ensure that its interaction with the ZF-AS Tronic transmission control unit functions correctly. In order to ensure optimum shift processes, the inertia torque of the clutch disc must furthermore not exceed a maximum value (refer to table).
• Use shims as defined in ISO 7089/7090. • Observe specified tightening torque. M10 46 ± 5 Nm M12 79 ± 8 Nm • Note additional thermal load (e.g. using 10.9 bolt with tightening torque for a 8.8 bolt). CAUTION Do not use toothed locking screws! Secure with stud bolts If the ZF-AS Tronic and/or ZF-AS Tronic mid is fastened to the flywheel housing via threaded pins attached at the engine end, the stud bolts must not protrude by more than 62 mm.
– The clutch requirements are described in specification no. 1328 761 053. – Installation drawing 1328 600 019/043 illustrates the clutch installation space. The installation dimensions apply to the AS Tronic and the AS Tronic mid.
Reasoning: If they protrude any more, it is very difficult to disassemble the transmission actuator for service work. In extreme cases, the transmission has to be removed for such purposes.

Deviations from the standard (e. g. applications with 2-disc clutches, other clutch diameters) must be agreed with ZF in writing. Since the clutch is actuated via the ZF-AS Tronic transmission control unit, the service life of the linings is higher than that experienced in average applications with manual transmissions. The reasons for this are: • Always optimum engine speed during setting off processes => less friction work in clutch. • The transmission control unit controls upshifts so that there is only a small difference in speed between the engine and transmission when engaging the clutch => less friction work. • During downshifts, the transmission is synchronized by the engine => no friction work.

ZF-AS Tronic
Installation To design the push rod, ZF needs the dimensions (A, X, Y, and Z) and tolerances shown in Fig. 4.1. These are acquired in the customer specification.
4.1.6 Clutch Release Unit ZF-AS Tronic and ZF-AS Tronic mid are supplied with release bearings as standard. The OEM therefore no longer needs the clutch actuator on the assembly line. The snap ring on the release bearing is the transmission's interface to the clutch.
CAUTION If the ZF-AS Tronic or ZF-AS Tronic mid is used for the transport of dangerous goods, additional measures will be required on the clutch actuator. Contact your ZF partner for more details.
– The process for installing the clutch is described in Section 4.7.5.

The permissible clutch release force is 8 000 N. Higher levels of release force must be approved in writing by ZF Friedrichshafen AG. NOTE In such cases, the pressure warning threshold and release pressure of the pressure relief valve must be adapted to the higher pressure level. Length of push rod is configured by ZF.

A ball bearing which is sealed on both sides and supplied with lifetime lubrication is needed to permanently guide the transmission input shaft. The sealing material must be resistant to temperatures of between –40 and +150 °C. The antifriction bearing grease must also be resistant to temperatures of between –40 and +150 °C. It is assumed that the sealing material is resistant to corrosion.

Installation ZF proposal for suspension
4.1.8 Suspension Only the screw surfaces on the transmission housing and/or on the attachment unit intended for the purpose may be used for the transmission suspension. Housing material GD-AlSi9Cu3 is defined as the key strength values for the screw configuration, material F270 and surface treatment Fe/Zn6B DIN 50961 are defined for versions with threaded bushes.
D
A
Suspension at A + B (on both sides) Additional suspension point D only in special variants.
Following discussions with ZF, transmission bearings on the vehicle frame must be designed so that no additional forces are transferred to the transmission housing by vehicle frame distortions.
C
The additional suspension D is only needed if the corresponding measurements, calculations or tests indicate a critical vibration influence or extreme shock impacts. It should however be noted that when rubber bearing D is in the datum position, no forces are transferred and the rigidity of D is less than that of bearing A + C and/or A + B. If suspension point D is needed, all 3 threads should be used (for screw-in depth, refer to installation drawing).
Suspension at A + C (on both sides), approval required. Additional suspension point D possible, but not necessary – even for ZF auxiliary power units.

DANGER The bending torque MC of the bearing supports on mounting face C must not exceed the limit value of 1 900 Nm.
Lateral suspension at point C is not possible in pressure die casting housings of product families 1+2. If suspension is required at point C, a sandcast housing must be applied. – For calculation of MC, refer to Fig. 4.6.
SAE2 engine connection (product families 1+2) If suspension at point C is used, written approval must be obtained from ZF. If connection deviates from the ZF proposals in Fig. 4.3, ZF MUST be contacted.

4.1.9 Transmission Installation Angle The longitudinal transmission inclination must not exceed 5°. The ZF-AS Tronic can endure a total inclination (vehicle inclination incl. transmission inclination) of 17° without any damage. This corresponds to a gradient of: • 21% at 5° transmission inclination. • 30% at 0° transmission inclination.
Installation angle (longitudinal)
Greater gradients may only be travelled briefly. Written approval from ZF is required if the vehicle application is associated with frequently occurring, greater gradients and with other transmission combinations. The transmission installation angle (transverse) may be up to 3°. Written approval from ZF is also required.

Simple configurations
Multiple arrangements
The axles should be mounted appropriately for all vehicle load statuses so that a precise propshaft Z configuration (β1 = β2) can be achieved.
By selecting an appropriate spider position and varying the height of the intermediate bearing (β angle distribution), the propshaft can often be optimized with multiple arrangements.

4.1.17 Additional Guidelines for Vehicle Body Manufacturer
4.1.18 Vehicle Wiring
The reciprocal dependencies of the vehicle electronics must not be destroyed by modified cable routing (refer to system design). If fundamental changes are undertaken to the installation and these affect the ZF-AS Tronic, ZF installation approval ceases to apply.
• Do not bend the cables.
No other consumers may be connected on the pneumatic supply line to the ZF-AS Tronic after the pressure relief valve.
• Avoid relative movements (chafing) between wiring and surroundings e.g. vehicle frame.
The following should be noted in particular by vehicle body manufacturers – Section 4.4 Electrics, TKI 6029 705 003 Vehicle wiring, TKI 6009 796 001 Transmission actuator – Section 4.5 Pneumatics
(Note TKI 6029 705 003 vehicle wiring)
• Observe temperature range (refer to ambient temperature section). • Do not secure to water, oil, or pressure lines. • Wiring must not be tightened hard.
• Te distance between the wiring and generator must be at least 200 mm. • Note possible EMC faults. Do not route cable near HF lines. • Do not connect ground/earth cables to transmission. • When undertaking arc welding on the vehicle, ensure that current does not flow through the transmission and associated electronics. • The wiring must not be affected by work undertaken on the vehicle. • Wiring between the transmission actuator and vehicle must be secured to the transmission max. 200 mm downstream of the 20-pin plug connection. Once work near the lines has been completed, they should be checked for damage and plugs checked to ensure that they are fitted correctly. This also applies to the pneumatic lines, oil lines, and water lines (e.g. with Intarder).

ZF-AS Tronic 4.2
Temperatures
Temperature measuring runs are required for approval for all ZF-AS Tronic applications. During these runs, the temperatures gained • on rising gradients • on downward gradients • once the vehicle is parked should be recorded in particular. The customer must use these measurement runs to prove that • the max. ambient temperature (on the transmission actuator)
Installation 4.2.2 Permissible Oil Temperatures For CV applications with and without intarder, a permanent temperature of 110° C is permitted, measured in the transmission oil sump. Short (max. 30 min.) peaks in temperature of up to 130 °C are permitted. In total, these peak values may make up max. 10 % of the oil change interval. • For special vehicles (cranes, fire service vehicles etc.), we also recommend temperature measuring runs. The same permissible temperatures as those for normal commercial vehicle applications apply.
4.2.3 Causes of Excess Oil Temperatures
• the temperature in the transmission actuator and • the permissible permanent temperature are below the limits specified here. Measures for reducing temperature must otherwise be initiated.
4.2.1 Permissible Ambient Temperatures on Transmission Max. ambient temperature 95 °C (at distance of 50 mm from transmission) This temperature is measured near the transmission actuator cover.
The following points may cause the permissible temperatures to be exceeded: • Encapsulated and noise-insulated transmission installation. • Insufficient distance between exhaust / turbocharger and transmission. • Air cannot be exchanged with the transmission surroundings (measures on vehicle). • Influence of heat from fitting third party retarder. • Very high and/or very low driving speed. • Oil level too high. • PTO output when vehicle is stationary.
The following measures are required: • Distance between exhaust, water pipes, and other sources of heat and transmission: min. 100 mm. • Fit baffle plate to vehicle.

Installation
4.2.4 Additional Transmission Cooling
A heat exchanger is connected.
If the permanent temperature in the oil sump is still above 110 °C, additional cooling is needed.
The ZF-AS Tronic has the connections needed for a heat exchanger. – Refer to installation drawing in Section 4.1.1.
The following applications without intarder require standard equipment of auxiliary cooling:
When connecting up a heat exchanger (WT), the following should be noted:
• Product families 3 + 4: -
Normal applicaltion and gross vehicle weight > 60 t Exception: occasional application (< 10%) up to 90 t
-
Vehicles with special bodies or continuous service in extreme topographic conditions.
• relatively warm climatic zones (>40° C) from 40 t Additional transmission cooling is not required for applications with intarder. • Product families 1 + 2: -
Vehicles with special bodies or continuous service in extreme topographic conditions.
Product families 3 + 4: An external oil-water heat exchanger can either be fitted in the factory and supplied with the ZF-AS Tronic or retrofitted onto the ZF-AS Tronic. In the event of subsequent attachment, painting of the heat exchanger must not be forgotten (cf. Section 4.7.4). The cooling rating of the heat exchanger can be taken from the installation drawing (refer to installation drawing + heat exchanger, Section 4.1.1). There must be a by-pass line (by-pass valve, 1.0 bar) upstream of the heat exchanger between the heat exchanger inlet and heat exchanger outlet ends. The transmission must not be operated while the heat exchanger is not connected up. Product families 1 + 2: The transmission can be fitted with an integrated heat exchanger and therefore does not need an external by-pass valve. – Chap. 4.3 and the relevant installation drawings should be noted with regard to filling oil and the oil level check in conjunction with a heat exchanger.

4.3.3 Draining the Oil
4.3.4 Filling With Oil
Always change the oil after a long journey while the transmission oil is still at operating temperature and thin.
• Top up oil through oil fill aperture. - The oil level is correct when it has reached the bottom edge of the filler hole and/or when oil is already escaping out of the filler hole.
!
DANGER! Touching hot parts and transmission oil may cause burns.
• Remove oil drain plugs from transmission and collect transmission oil in a suitable container and dispose of in accordance with environmental regulations. • PF 3+4 only: Clean oil drain plug and magnetic plug.
CAUTION In case of a transverse transmission installation angle, ensure that the transverse inclination corresponds to 0° for filling in the oil, otherwise the oil quantities will be incorrect. – The position of oil fill apertures and the oil fill plugs can be seen in the relevant installation drawing (Section 4.1) and the technical manual for the Intarder (ZF no. 6085 765 104).
• Replace oil drain plug seal ring. • Tighten oil drain plugs to 60 Nm. The transmissions of the AS Tronic families have one or more oil drain plugs, depending on the version. – The position of these plugs can be seen in the relevant installation drawing (Chapter 4.1) and the technical manual for the Intarder (ZF no. 6085 765 104).
4.3.5 Oil Level Check !
DANGER ! Too little oil in the transmission will result in transmission damage. Risk of accident!
Check the transmission oil level at regular intervals: • Check oil level when vehicle is on horizontal ground. • Do not undertake the oil level check right after travel (this will produce an incorrect measurement). Only undertake the check once the transmission oil has cooled down (< 40 °C). • Remove oil fill plug. • If the oil level has fallen below the oil fill aperture, the oil must be topped up (in accordance with Section 4.3.4). • Tighten oil drain plug to 60 Nm. NOTE Whenever checking the oil level, also inspect the transmission for leaks.
1328 765 101 - 2007-10
4-26
ZF-AS Tronic 4.3.6 General Information Even if reference is made here and in the aforementioned documents to particular volumes, ensure that the oil level is correct on the transmission itself. To do this, one of the oil fill apertures in the horizontal vehicle must be filled with oil until the level has reached the lower edge of the fill aperture and/or oil is escaping from this fill aperture. For Intarder applications and applications with heat exchangers, please note that the the oil is only filled fully once the vehicle has been moved and a second filling process is reached (refer to technical manual for Intarder ZF no. 6085 765 104).
Installation 4.3.7 Information about Bleeding the Transmission The transmission is fitted with a vent on the transmission actuator as standard. The vent should be protected from the ingress of large amounts of water. The breather must be clean and must not have its plastic cover fitted. In special applications, such as off-road vehicles, refuse collecting vehicles and milk collecting vehicles, which are frequently cleaned using a jet of water, moisture or moist air may be drawn into the vent as a result of sudden transmission cooling, causing condensation to form inside the transmission. Since the proportion of water in the transmission oil must not exceed 1 000 ppm, rather than the standard vent, ZF recommends that a a hose-type vent be installed in the vehicle’s dry compartment. The interface on the transmission to the hose may be supplied having been fitted in the factory. A retrofit kit for hose venting is available under ZF number 1315 298 021 from ZF-Service.

ZF-AS Tronic 4.3.8 Venting by Means of Hose Line in Dry Compartment ZF recommends this type of venting as standard. This provides the best possible protection for the transmission against water ingress. When using this form of hose venting, the oil change interval for ECOFLUID M transmission oil increases. More information on this can be found in the List of Lubricants TE-ML 02. Notes on the “dry compartment” and routing of the hose:
Installation • Max. permissible hose temperature (e.g. near exhaust pipes, exhaust turbo charger) must not be exceeded. • End of hose lowered by approx. 150 mm. • Light width of hose of at least Ø 4 mm. • Fording capability according to vehicle specification must be retained. The vehicle manufacturer is responsible for the correct fitting and routing of the hose.
“Dry compartment” is defined as follows: ca. 150mm
• protected against spray water • low air humidity (Example: Engine compartment, under engine hood)
correct incorrect
The following should be noted when fitting the hose (also refer to sketch): • Ensure that the hose exits the transmission vent horizontally (use angled screw connection if necessary). • Route hose so that it rises continuously. A siphon effect should be avoided (see sketch). • No bends, chafing points. Route hose in the largest radius possible.

4.4.4 CAN Bus Installation The vehicle manufacturer is responsible for the CAN bus installation! The vehicle end connector on the transmission actuator can be used to integrate the ZF-AS Tronic into all known CAN bus topologies (linear CAN connection, non-linear CAN connection). Experience has shown that an unsheathed twisted CAN line (twisted pair) is sufficient for most applications.
Linear CAN connection (no tap lines) refer to Fig. 4.19 From today’s standpoint, an economically and technically (EMC aspects) good solution, relatively insensitive to faults, even with high transfer rates (500 kb) the linear connection is relatively insensitive to faults.
R1
The non-linear connection is more sensitive to faults, but a simpler form of CAN network. Here, what is commonly referred to as a tap line is formed between node point (point B) and electronics (point A). This tap line must not exceed the maximum length defined in the standards (refer to standards SAE J 1939, ISO/DIS 11898). If there are deviations from the maximum specified lengths, transfer faults may occur (e.g. when using terminal testers or intermediate cable kits etc.).
Line version The line version must also be designed in accordance with existing standards (SAE J 1939 and/or ISO/DIS 11898), which specify twisted and/or twisted + sheathed.
The ZF transmission system supports this type of CAN connection. The CAN lines are piped within the TCU (2 connections each for CAN_H and/or CAN_L).

Bus terminal resistance The transmission control unit (TCU) has an integrated bus terminal resistance which can be activated via the wiring on the electronics connector. The electronics can therefore be used as CAN BUS end consumers and/or as central consumers. If the transmission electronics are produced as CAN BUS end consumers, the line bridges in the electronics connector (vehicle power connector) must be used as shown in Fig. 4.21 (bridge from PIN 13 to PIN 15).

4.4.5 Quality Requirements of Wiring A distinction is made between two fundamental installation situations. 1. Wiring which is routed in the cab and/or in the vehicle frame. 2. Wiring which is routed on the ZF unit and/or directly next to the unit or engine. More stringent requirements apply here in terms of temperature, mechanical properties, resistance to media. – If the cable from the power supply connector (on the transmission actuator) is produced by the vehicle manufacturer, then technical customer information TKI 6029 705 003 should be noted.
Routing and securing Wiring in the vehicle should be routed so it a) is not damaged b) can be accessed at any time
1328 765 101 - 2007-10
028966_en
The wiring should be routed and secured in a protected part of the vehicle. The cable must be secured at a maximum of 20 cm downstream of the transmission power supply connector. Loose hanging wiring is not permitted. The connectors must not be tightened down too firmly. Ensure that the connectors and mating connectors are compatible and snapped in. Also ensure that there are no relative movements, e.g. between vehicle frame and transmission, which damage the wiring. The securing material must be selected ensuring that the wiring is neither squashed nor damaged or pre-damaged in any way. CAUTION A sufficient distance should be maintained from sources of heat, such as exhaust, heat exchanger etc. and/or thermal protection should be fitted. – Other techn. requirements can be found in TKI 6029 705 003.

4.4.7.2 Speedo Sensor There is an output speed sensor on the ZF-AS Tronic which provides the tachographs with the relevant signal (refer to installation drawing).
4.4.7.1 Neutral Switch (S12) The transmission neutral switch (S12) is located on the transmission in position G32 (refer to installation drawing). The starter current circuit is connected with the transmission neutral switch via relay E17 so that the engine cannot be started when a gear is selected. If the transmission is mechanically in Neutral, the neutral switch contact is closed. One neutral switch is available for the ZF-AS Tronic: • Switch: Ref. 0501 215 297 (bayonet connection in accordance with DIN 72585)

4.4.8 CAN Signals
4.4.9 EMC Compatibility
ZF TKI 1328 761 005 contains descriptions of the requirements of the external signals needed to operate the ZF-AS Tronic; it also contains descriptions of the signals which are transmitted by the ZF-AS Tronic. The quality, and accuracy as well as (if necessary) the repeat rate needed (CAN) are also defined for each external signal.
The E1 certificate issued by the Federal Vehicle Registration Authority can be requested from ZF.
Most of the signal’s requirements correspond to those defined in SAE J 1939. The ZF-AS Tronic only expects deviating, higher repeat rates for a few signals. In line with the present development level, these are • the accelerator pedal position (with idling switch) • the wheel speeds from the ABS. The signal specification of the TKI 1328 761 005 must be confirmed by the vehicle manufacturer. Deviations from these should be agreed upon in a special manner. The following characteristics must be observed in addition to the requirements described in the signal specification: • Brake pressure on the wheel. As soon as the vehicle experiences retardation, i.e. braking action, there must be a foot brake signal. In other words, at a braking pressure of 0.2 + 0.2 bar on the wheel, the foot brake signal must be set and should then drop back below this value. • Accelerator: The characteristics of the accelerator have a significant impact on the maneuvering and setting off characteristics of a vehicle with an AS Tronic transmission system! (Accelerator replaces clutch pedal ! The following should therefore be noted: - The idling switch signal should drop at 4 + 2% of the accelerator. - The kickdown signal should be present at >100% of the accelerator position with a pressure point that can be clearly felt.

ZF-AS Tronic 4.5
Installation
Pneumatics • In example 1, the air supply for the braking system takes priority over the shift system, since an relief valve (> 5 bar) is mounted in front of the ZF-AS Tronic air circuit. The pressure level set on the relief valve must however be less than the pressure level of the relief valves in the 4-circuit protection valve for the auxiliary consumers.
The quality of the air supplied to the ZF-AS Tronic system is very important for vehicle availability. The same requirements as those placed on the braking systems therefore apply to air quality and air line versions. The air supply for the ZF-AS Tronic system can be connected up the vehicle’s air system, either upstream of the 4-circuit protection valve (example 1), or downstream of the 4-circuit protection valve on the auxiliary consumer circuit (example 2). The following should be noted here:
• In example 2, the air supply for the ZF-AS Tronic takes priority over the other auxiliary consumers since this is mounted upstream of a relief valve (> 5 bar).

ZF-AS Tronic
Installation
Air reservoir
Air lines
A separate air reservoir is fitted for the ZF-AS Tronic and is protected by a pressure relief valve. Other consumers must not be connected up to this compressed air circuit – with the exception of the ZF-Intarder. The pressure relief valve prevents the pressure in the air reservoir from falling when there is a leak or insufficient air in the rest of the air system. Minimum volume of air reservoir: • ZF-AS Tronic 10 dm3 • ZF-AS Tronic + IT 20 dm3
The air lines from the ZF-AS Tronic air reservoir to the transmission actuator and clutch actuator must have a nominal width (interior diameter) of at least 9 mm. Maximum lengths of 4 m must not be exceeded.
Air pressure
Air dryers which emit alcohol or other substances into the air system which may have a negative impact on sealing materials are not authorized.
Supply pressure needed 8 -12.0 bar downstream of air drier. To ensure that sufficient shifts can be undertaken when there is insufficient air, ZF-AS Tronic has to be supplied with a supply pressure of at least 8 bar. The transmission actuator uses an integrated pressure reducing valve to reduce the air pressure to 7 bar of shift pressure to preserve the shift elements and to achieve constant shift characteristics. Reliable shifting and connection of the shift system is ensured with a shift pressure of 7 bar. Shift pressure
Supply pressure
Air quality The compressed air made available to the vehicle must be cleaned, dried and free of condensate. Air particle filter: 40 microns mesh width.
Maximum permissible water content of compressed air: 15 % (relative air humidity). Ambient temperature [°C] -20 -10 0 10 20 30 40
= Pressure in transmission actuator downstream of pressure relief valve = Pressure in air reservoir
Water content [g/m3] 0.136 0.332 0.726 1.41 2.6 4.55 7.66
Pressure display / warning Air consumption Air displacement volume needed: At least 5 dm3/min at 8 - 10 bar. The vehicle air system should be designed so that at least the aforementioned volumetric flow of air is made available to the ZF-AS Tronic air circuit alone. This assumed requirement is based on the consumption needed for 9 shifts and 1 starting process (“ignition on” with clutch actuator calibration) per minute.
1328 765 101 - 2007-10
A pressure sensor is integrated in the transmission actuator and provides the driver with a warning when the pressure level of the shift pressure falls below 5.8 bar. This information is shown on the ZF display (AL) and/ or can be sent to the CAN as a message.
!
DANGER! If gear shifts are undertaken with insufficient air pressure, the transmission may remain in Neutral so that there is no direct drive and no engine brake effect.

Installation If ZF expressly refuses to issue approval for a third party retarder, then ZF assumes no warranty or liability for this unit combination, or for the functional and operating safety of the entire system.
Auxiliaries
4.6.1 ZF-Intarder The ZF-Intarder cannot be retrofitted. The ZFIntarder must always be taken into consideration when ordering the transmission.
4.6.3 ZF Power Take Off Units (PTOs) For ZF-Intarder applications, particular attention should be paid to the peripheral parts such as the fitting of electronics, wiring, and cooler connection at the water end. The pulse count of the speedo sensor changes slightly to that of applications without an Intarder.
ZF PTOs can either be fitted in the factory when the transmission is supplied, at a later date by the vehicle manufacturer or in the end customer’s complete vehicle.
– Installation instructions and interface descriptions can be found in the ZF-Intarder technical manual (ZF no. 6085 765 104).
– The type sheet for ZF PTOs, ZF nos. 1328 757 152 (PF3+4) and 1336 757 151 (PF 1+2) provides information on the selection of ZF PTOs available. The fitting specifications have to be drawn up in conjunction with ZF and the vehicle manufacturer.
The exchange of signals needed with the ZF-AS Tronic via the CAN bus is taken into consideration in the ZF-Intarder electronics software.
Particular mention should be made here of the fact that when a PTO is mechanically fitted, the electronics in the ZF-AS Tronic need additional programming to guarantee the operating safety of the system in conjunction with the automated clutch. When the vehicle manufacturer is fitting the PTO, the technical data set should be clarified with the technical sales team. When retrofitting on supplied vehicles, this is undertaken by the ZF service center. If a PTO is fitted without the ZF fitting instructions (e.g. electronics program modification) being observed, then ZF assumes no warranty for this unit combination, the functional and operating safety of the entire system.
– Special features of oil fills for the ZF-AS TronicIntarder combination can be found in the ZFIntarder technical manual (ZF no. 6085 765 104). Initial installation of a ZF-AS Tronic and ZF-Intarder system combination must be commissioned and approved by ZF.
4.6.2 Third Party Retarder If third party retarders are fitted, the ZF technical sales team must always contacted. Requirements relating to the mechanical, pneumatic, and electrical interfaces and the exchange of signals with the ZF-AS Tronic must be coordinated. If necessary, the system safety of the entire unit must also be taken into separate consideration and a vehicle entire system FMEA undertaken by the vehicle manufacturer.
1328 765 101 - 2007-10
The peripherals (wiring harness etc.) needed for the ZF PTOs have to be ordered from the vehicle manufacturer. If retrofitting on a vehicle which has already been supplied, the ZF service centers will assist.

In the event of subsequent attachment, painting of the heat exchanger must not be forgotten (refer to Section 4.7.4). The assembly specification and positioned assembly drawing should be noted! – refer to installation drawing + heat exchanger, Section 4.1.1 and additional cooling, Section 4.2.4

The transmission must not be suspended from its input shaft (e.g. during transport) (because this would damage bearings and splines). The ZF-AS Tronic must also not be suspended in slings for transport purposes. CAUTION If the transmission is flange-mounted to the engine, no transport attachments must be fitted to the transmission. The lugs are only configured for the weight of the transmission. ZF is not liable for transmission components being damaged through incorrect transport.

4.7.2 Supplying the Main Transmission Depending on customer requirements, the ZF-AS Tronic is supplied as follows: • With the highest gear selected • In Neutral
This results in the following assembly sequence: • The guide pipe must be free of grease. • Remove corrosion protection from input shaft spline and grease (with approved grease following clutch manufacturer specification). • Slide clutch disc onto input shaft spline. • Remove clutch disc and wipe off surplus grease.
4.7.3 Corrosion Protection We recommend coating the ZF-AS Tronic with standard anti-corrosion inhibitor. In special applications with a high risk of corrosion (e.g. snow clearing …), special anti-corrosion protection measures are needed and can be defined on request.
The ZF-AS Tronic is supplied painted in black as standard. If the customer would like to paint the ZFAS Tronic himself, this must be done in accordance with ZF specification:

4.7.6 EOL Programming
Documentation of EOL (End Of Line) programming
The ZF-AS Tronic software can be programmed by the vehicle manufacturer to reduce supply and/or service variants of the ZF-AS Tronic.
The delivery status of the ZF-AS Tronic is documented by ZF using the vehicle manufacturer’s order number.
For the EOL (end of line) programming of ZF-AS Tronic-specific vehicle variants outside the ZF organization, the vehicle manufacturer and ZF must agree on the program variants needed as well as the documentation, production, and service process requirements.
All EOL programming/parameterization actions and modifications taking place outside the ZF organization and during the service life of the transmissioncontrol unit (TCU) must be understandable for ZF. A database is used for ZF documentation. The “vehicle manufacturer – ZF” transfer of data should be defined using appropriate procedures.
Transmission software must be adapted to the vehicle configuration. This may be done by means of signal exchange between transmission control unit (TCU) and the vehicle control unit(s) or through EOL parameterization performed by the vehicle manufacturer or ZF. Adaptation of the transmission software to the vehicle configuration is defined in accordance with the application. The ZF-AS Tronic is programmed using serial data transfer.
1328 765 101 - 2007-10
ZF-AS Tronic-specific data which has to be documented by ZF is discussed with the OEM.
ZF external programming equipment ZF-AS Tronic-specific data present for EOL programming has to be forwarded to ZF. A standardized procedure should be defined for this purpose.

4.8.1.4 Moving off Downhill Requirements: Engine is running If the parking brake is released when a gear is selected and the vehicle rolls off, the clutch automatically closes without the driver having to press the accelerator.
4.8.1.3.2 Maneuvering acc. to rotary switch position DM or RM The system recognizes the maneuvering mode according to the position of the rotary switch. 1st gear and 1st R gear are available for maneuvering. In this maneuvering mode, the entire accelerator pedal travel can be used. To quit this mode, the rotary switch needs to be switched to position « D », « N », or « R ».
!
DANGER! When the vehicle moves off without a gear selected – rotary switch in position “ N “ – the engine brake will not work! Do not allow vehicle to roll in direction opposite to that of the gear selected.
If the vehicle rolls forwards – transmission in Neutral – once the brake has been released and you shift from “ N ” to “ D ”, the system selects a gear appropriate for the driving speed. The driveline is therefore closed.

4.8.1.6 Changing Gear
4.8.1.7 Reverse Travel !
Changing gear in Automatic operating mode.
DANGER! If the vehicle is rolling, a shift is not made into reverse gear! Immediately bring the vehicle to a standstill.
• All upshifts and downshifts are undertaken automatically. This depends on: • Drive resistance • Loading • Accelerator position • Velocity • Engine speed The gear display appears on the display during travel as a number.
Select reverse gear:
024376
• Vehicle must be stationary. • Turn rotary switch to “ R ” or “ RM ”. • “ R ” or “ RM ”appears on the display (clutch remains separated). • Depress accelerator and release brake at the same time (clutch closes automatically). • Vehicle travels backwards
Changing gear in Manual operating mode Change in direction of travel. • Press control lever in « + / + » or « – / direction. • « +/– » change by one gear step • « + / – » change by two gear steps
–» Reverse travel “ R/RM ” to forwards travel “ D/DM ” and vice versa. • Turn rotary switch from “ R/RM ” to “ D/DM ”.
The shift system exits the Automatic operating mode when a manual shift is undertaken. If you press the control lever to the left, Automatic operating mode is again activated.
!
DANGER! Changing direction of travel by moving the rotary switch from “R/RM” to “D/DM” and vice versa may only be undertaken when the vehicle is stationary, otherwise the transmission shifts to Neutral. The display is definitive for the direction of travel selected in the transmission.
NOTE • You can shift from any gear to Neutral at anytime using the rotary switch. This shift request takes priority over other requests. • The accelerator position must not be changed during the shift process because the engine is controlled electronically. • A shift command is not undertaken if the shift would result in the max. permissible engine speed being exceeded.
!
DANGER ! Shifts to “Neutral” can also be made during travel. If a shift is made to “Neutral”, the driveline is interrupted. The engine brake then no longer functions.

ZF-AS Tronic 4.8.1.8 Engine Brake !
DANGER! The engine brake function is interrupted during the gear shift. The vehicle may accelerate when traveling downhill.
Manual operations The engine brake is deactivated by the system during gear shifts. Once the gear shift is complete, the engine brake is automatically reactivated. Automatic operation By activating the engine brake, the system downshifts so that maximum braking torque is reached.
4.8.1.9 Stopping • With the accelerator untouched, slow down the vehicle using the service brake until it reaches a standstill. • The clutch opens automatically before the vehicle reaches a standstill so that the engine does not “stall”. • If the vehicle is going to be stationary for long periods of time, we would recommend selecting the Neutral transmission position. • Always engage the service or parking brake when the vehicle is stationary.
!
DANGER! • When the vehicle is stationary with the engine running and a gear selected, you need simply press the accelerator in order to move the vehicle! • Before leaving the vehicle with the engine running, the transmission must be shifted into Neutral and the parking brake engaged. • Activating the parking brake during travel and on a smooth surface may bring the engine to a standstill. Steering assistance is then no longer available!
1328 765 101 - 2007-10
Installation 4.8.1.10 Switching Off Engine / Stopping Vehicle • • • • •
Bring the vehicle to a complete stop. Apply parking brake. Move rotary switch to “ N “ Neutral. Switch off engine via ignition key. Place chocks under wheels (e.g. on slopes).
!
DANGER ! The engine cannot be switched off if a gear is selected. The vehicle may roll away if no brakes are engaged. Engage parking brake.
NOTE If the transmission is not shifted to Neutral before the engine is switched off, this is done automatically when the ignition is moved to “Off ”.
4.8.1.11 Towing The vehicle can be towed with a flange-mounted propshafts or a stub shafts. To this end, the following conditions must be satisfied: • Ensure that the high range change group is activated. To this end, the secondary conditions to be satisfied are as follows: 1. Ensure current and air supply. 2. Switch the ignition ON (wait check phase). 3. No error message appears. Therefore, it is ensured that the high range change group is activated. • No gear is engaged in the main transmission. • Towing distance of max. 100 km. • The max. permissible towing speed depends on the rear axle ratio and the tire dimension as described in Fig. 4.26 on the diagram. The respective national specifications have to be taken into account with regard to the max. permissible towing speed.

NOTE Select an operating mode in which there is no risk of clutch overloading, for example: • Accelerate vehicle (to close the clutch). • Stop. • Set off and / or maneuver in a lower gear.
INFORMATION It is totally forbidden to tow with a flange-mounted propshaft or mounted stub shafts if the following indications are present: 1) One of the conditions already described is not satisfied. 2) An error message appears (140) or it cannot be ensured that the high range change group and the main transmission are switched to NEUTRAL (i.e. vehicle breakdown undefined, failure of circuit and/or air supply). 3) Transmission damage suspected.
!
DANGER! If the driver ignores the warning, the clutch will close when the accelerator is depressed. This prevents the clutch from being further overloaded. This may cause the engine to “stall” and rolling backwards downhill cannot then be ruled out. The clutch opens again when you take your foot off the accelerator.
CAUTION Towing the vehicle with an activated slow range change group or an engaged gear in the main transmission rapidly leads to major transmission or engine damage. The operator assumes the responsibility for towing with a flange-mounted propshaft or a stub shaft (ensuring that all the required conditions are satisfied). If the vehicle is towed with a flange-mounted propshaft, prevent pollution through possible oil losses. When towing, also observe the instructions of the vehicle manufacturer.
1328 765 101 - 2007-10
If there is a risk of the clutch being overloaded by several starting procedures undertaken one after another in short succession or by a long period of maneuvering in too high a gear, the “CL” display appears.
• To preserve the mechanical parts of the clutch release mechanism, you should shift the transmission to Neutral when stopping for long periods (more than approx. 1 to 2 min., for example in queuing traffic, at traffic lights etc.). The clutch is thereby closed and the clutch release mechanism relieved. Despite the clutch being automated, the driver still has considerable influence on the clutch’s service life. To keep clutch wear levels as low as possible, we would recommend always selecting the lowest gear possible when setting off.

4.8.1.14 Engine Overspeed Protection
4.8.1.15 Operations with Clutch-Driven PTO
To protect the entire driveline from excessive speeds, the ZF-AS Tronic only allows gear shifts which are within the speed range defined by the vehicle manufacturer.
Stationary/Mobile operations • Depending on the type of transmission, only certain gears will be available for stationary/ mobile PTO operation (refer to Section 3.1.7).
Operating mode: Manual • Ensure that the engine does not exceed the permissible speed range. • If the vehicle speeds up when traveling downhill, there is no automatic shift into a higher gear. CAUTION The engine may be damaged if the vehicle speeds up when traveling downhill and the engine enters the overspeed range.
• Gear shifts are only undertaken when the vehicle is stationary. Gear changes during travel are not possible. • Engage PTO and select starting gear. • The following appears on the display e.g.:
024406
Operating mode: Automatic
!
DANGER! The vehicle may speed up when traveling downhill. To protect the engine from damage in the overspeed range (red range), the system undertakes an upshift.
i.e.: PTO 1 is activated, starting gear 3 is selected (refer to Section 2.4.4).
Stationary operations During stationary PTO operations, no gears can be selected. The transmission remains in Neutral.
