JT- 901 is an automatic control for precision air- conditioning equipment. It makes that temperature and relative humidity be kept using set points, also including reception and display of working and alarms states. Parameter programming is made in an easy way. It offers the possibility of a remote monitoring of alarms and working states. It establishes a connection with a monitorized system, which is capable to remote programming using a modem.
2.
General view.
Control is located in the front part of the inner unit. for display purposes, it has 2 displays and several control leds, and also several buttons for controlling and programming the different variables. JT- 901 is configurable by the user, using a keyboard, which is located in the frontal face of the control. Programming data storage is provided by a non- volatile EPROM, which is 10 years capable. System allows user protection by a password. Control basically has three main parts: an interface console, an I/O Microprocesor board with a power supply unit and a combined temperature and relative humidity sensor. It also can attach a fourth element as an option, which provides a proportional stage. •
Console is user’s interface system . A 2 x 16 LCD screen show a view of working states, temperature and relative humidity values, alarms,...formed by a main boards, which are absolutely independent. Connected to main board using a RJ11 conection. Includes a keyboard board that allows to change working parame-ters (temperature and humidity set poi nts), and can configure working and alarm states introducing a pasword.
•
Input/output Micro processor Board is the brain device that controls whole system. It receives signals, using free voltage contacts, from different working and alarm states. It also generates control signals to activate necessary elements. It is absolutely free- perturbations produced by the machine and other exter-nal agents. I/O Mainboard can operate without console interface.
•
Temperature/Relative Humidity probe. Combined relative humidity and temperature sensor has a temperature stage (PT100 preamplifier), a relative humidity stage (with preamplifier capacitive sensor).
•
Optional Proportional stage is an additional board for controls with freecooling option or air conditioning units. This device receives the value of a temperature sensor (PT 100), which is located into the input water of the coil, sending it to the control. Control will emit a signal that will modulate the valve depending on the taken value and environmental temperature.
•
Optionally, Network devicve can be installed in order to control operation fron 2 to 8 units. An RS485 Protocol is implemented to communicate all units.

Starting up with the main transformer, it generates and stabilized +5 V d/c, +12 V D/C and +24 V D/C supplies for the control. Each one has a led. All the supplies are stabilized and protected by fuses, varistors and transzorbs diodes, which make the control shielded against external perturbations. Digital input signals are obtained by voltage free contacts at 0 V. Main transformer phases and all the signals are protected optoelectronically. One 24 V A/C phase from the main command transformer is provided protected by fuses to excite the coil of external contactors (cooling 1, cooling 2, heating 1,...). Those fuses have a break indication via a red led in line with the fuse. Board is serigraphied so that is easy to locate each component. Control connection is made by one plane wire band and the input signals, power supply and output controls are made by male/ female connectors, making easy the change of the board.
C. Combined sensor. This sensor has been designed for air conditioning, refrigeration and industrial installations used, and because of this good design, can be used in environments with a great amount of electrical, mechanical and magnetical perturbations. It is powered by the relays board, and it can be powered within a great range of fluctuations. Sensor generates a lineal output signal that is proportional to the temperature, and another signal to the relative humidity. Temperature sensor is built with a PT100 thermoresistance and the humidity sensor is built with a capacitive transducer. Temperature and humidity measures obtained are sent to the I/O board using D/C signals. All associated electronics and sensors are included in a box, which is connected to the relay board using a fast connec-tor. Sensor includes an indicative led for displaying the power supply.
D. Optional expansion modules. D.1.- Proportional stage Module. It is an additional board for rail insertion, sized 100x54 mm. with fast connectors. This board is powered at +12 V D/C. This board receives a signal from water temperature sensor (PT100), stretching values between 0 and 10 Vdc, and sending them to the I/O board. Control analizes this signal enabling proportional valve and modulat-ing it depending on the environmental temperature. Signal that outputs from the I/O board is amplified in the proportional board and prepared to modulate the proportional valve. This board includes an indicative led for the power supply and IDC connection to main board. D.2.- Network Communication Module. It is an additional board for rail insertion, sized 100x54 mm. with IDC and RJ connectors. This board is powered at IDC connector from Main I/O board.

Working.
Once machine is started up, control has a set of timers and during a period of time, alarms are inhibited, so that elements can not start in a while until control be stabilized. When control is in a stable mode, machine-working states are set based on the temperature and relative humidity of the hall, activating demanded element. When an alarm occurs, it acts depending on the required algorithm. When alarms occur, they stay on memory when they disappear, and make sound an acoustic signal warning, indicating a failure on the machine. This signal will disappear when operator press the unlock key. In machines with two cooling stages, control changes between those two stages (weekly), so that use the two compres-sors will be equally timed.

Starting up.
Once machine has powered and A/C led is in on position, press I/O key and control will be on. When control is in on, it orders activation of the machine elements in a logical and progressive way, following the timers and inhibiting alarm signals during a while, so that machine can stabilize as soon as possible.
1. When the beginning of the first cooling stage is demanded, it will not start until 3 minutes. If the first 2. 3. 3.2.
heating stage or humidify is demanded, it will start in 30 seconds. In case of machines with two cooling stages, second stage is temporized to the first, so that high power demands will not occur. In a dehumectation demand in machines with two cooling stages, the second compressor will be responsible for making dehumectation.
Normal working state.
Once the starting period has processed, machine will reach a stablished state. Control will use the correct algorithms depending on the temperature and relative humidity signals. On two stages- machines, working of the two compressors is varied depending on the programming. On the enclosed graphics, it can be observed start of the stages, depending on the programmed set points. Default factory values are 22 ºC and 50 % R. H. Differential stage is the difference between temperature connection and disconnection of one stage. This differential can be adjusted between ± 0.1 ºC over all the scale range. The differential stage of relative humidity is set by default to 5 %. User Manual Control JT901/SMART Rev. 23.09.02

Dead zone: It is the difference between temperature and set valve. When control is working in the dead zone, it does not demand cooling or heating functions. This parameter can be adjusted between ± 0.1 ºC over all the scale range. The default value is 1 ºC. Dead zone for relative humidity is 10 %. There is delays between the cooling stages start to avoid frequent starting. This delay is 3 minutes, counting since the last starting. Next is enclosed a table showing different kinds of cases, taking into account needs of cooling and dehumecting hall. 1st Cooling Stage

Proportional Stage Working. Proportional stage will work when sensor that is located in input water coil, detects that water is below 1 ºC from the set point of the hall (freecooling units). In air conditioning units, proportional stage is always activated (there is a bridge between sensor connectors) and control sends a proportional signal depending on the environmental temperature of the valve. In freecooling units and when proportional stage is activated and hall temperature is over 1 ºC, it will consider that the freecooling coil is going to take some time in making lower the temperature in the hall, the cooling stage will start to help. Different messages are indicates on LCD screen to indicate unit status.

Alarm state.
When machine is in constant working mode, alarms actuation are instant, except next cases: • • • •
Low pressure alarm, temporized to 10 minutes once started compressor. Obstructed filters alarm, temporized to 90 seconds. Lack of airflow alarm, temporized to 30 seconds. Water under access floor alarm, temporized to 5 seconds.
When a compressor alarm occurs (thermal associated relay), it disconnects the compressor. If it is a low or high pressure alarm, message on screen. Thermal external unit alarm (thermal fancondenser), is merely informative, as it happens with water in technical floor alarm, but this also set the humidifier off. When some of the next alarms occurs, machine will stop; machine ready relay is set to off and in the display appears a nemonic. • Heat elements alarm: PRE OFF. • Lack of airflow alarm: FFA OFF. • Thermal fans alarm: TUR OFF.

User Manual Control JT901/SMART
A phase cut leaves control without power. It is indicated by a failure phase led. Also, machine ready led will be on, showing that problem is not due to the machine. Once one alarm has be produced, control emits an acoustic signal and it is stored in memory, although this alarm disap-pears, showing this alarm with a led. As actuation, operator should come to the control and press the OK key, so that alarm and associated led come void. In this moment, if alarm is disappeared, led will change from blink to off. If alarm continues, led will continue blinking.
3.4.
Stop.
There is a button that, if machine is powered, sets I/O board to OFF state, stopping at the moment all elements and providing an alarm signal to the sequencer. It should be noticed that in installations with sequencer, if machine is not in ON state, it will provide an alarm. When a power fault occurs, machine will stop, it will recover last state maintaining parameters configuration. Control is designed to output a signal via voltage free contacts when a fault power occurs. This is very useful to remote monitoring. In units with proportional stage board, when change of machine is required by sequence, valve will be closed.
4.
Alarms.
Different signals come to the control indicating actual state and alarms. The list below describes all these signals. •
Thermal I, Cooling II: It is an alarm in compressors, dues to overload have activated the thermal differential relay. In case of two stages, there are two alarms for thermal cooling in charge of the cut of the corresponding compressor.
•
High pressure alarm: It is an alarm from the cooling circuit, detected by the high pressure switch in charge of the cut of the corresponding compressor.
•
Low pressure alarm: It is an alarm from the cooling circuit, detected by the low pressure switch in charge of the cut of the corresponding compressor.
•
Obstructed filters alarm: the differential switch that provides a signal when filters are obstructed and is indicated by one led detects this alarm.
•
Water in technical floor: a sensor that sends a signal to the control detects presence of water. After a delay, it disconnects the humidifier, sets a led to ON, and the acoustic signal begins to sound.
•
Lack of air stream: This alarm is activated when fans have a lack of air stream. A differential pressure switch detects this and stops fans and the rest of the machine.
•
Thermal fan alarm: This alarm is activated when there is an overload in fans. Its actuation stops all elements in the machine.
•
Humidifier alarm: Humidifier control board provides a signal showing the presence of a breakdown. This is merely indicative, the acoustic signal will sound, and when it stops the led will blink.
•
Heat thermostat alarm: It comes from a temperature sensor located in the heating elements. When this alarm occurs, control disconnects all elements.
•
Lack of phases alarm: It is activated when some of the phases is missing and control is not powered, setting the corresponding led to ON and providing a general alarm signal.
•
Out of margin alarm: It detects a sensor failure or a wire breakdown. It has two levels: •
If during 15 minutes machine is working out of range (15 ºC to 30 ºC), acoustic signal sounds and machine will continue working.

User Manual Control JT901/SMART
If during 15 minutes machine is working out of range (15 ºC to 40 ºC), it stops machine.
Alarms that stop machine by a sequencer: In installations where machines are connected to a sequencer, control stops the machine and sends an alarm to the sequencer, changing work to other machine. Those alarms are the next: • • • • • •
Thermal compressors alarm. Pressure switches alarm. Filters alarm. Lack of airflow alarm. Heat thermostat alarm. Thermal fans alarm.
In this situation, acoustic signal that sounds is the one located into the sequencer (JT 801 one is off). In the display, SEC OFF can not be read.

User Section.
All programming is done in the factory by default and no external programming is needed. For informative purposes, there is some information about control programming. NOTE: changing internal programming should modify normal working of the machine and will be dangerous . Programming is done at two levels: Mode 1: Modification allowed to qualified and authorized users. It makes changes in set points of temperature and relative humidity. No internal parametres are allow to be programmed or changed. Mode 2: In this mode it can be configure delays in the actuation of the inputs/outputs cooling groups, heating, humectation and dehumectation, alarm settings, network configuration,... NOTE 1: When machine is powered, to starting up the control and attached devices, is necessary to press I/O key until the display is in ON state (control first duty is the autotest). NOTE 2: For entering in the programming modes, it is necessary to press the required combination of keys until the display shows the wanted legend. NOTE 3: In controls with proportional stage, when I/O key is pressed, a stack of lines appears showing that control is working in diagnostic mode. Next is shown a configuration example of the parameters in mode 1. If it is necessary to modify some of the rest modes, please inform to your dealer. Once analized this situation, a complete programming manual will be provided to you.

Annex 1: SMART/BUS Network. 7.
Introduction.
The AIRDATA equipments have always been at the vanguard when incorporating the last solutions in its work and control systems. Inside the evolution of the communication and remote work systems of the precision air conditioning units AIRDATA the existent system is revolutionized with the appearance of the SMART/BUS Network. Developed inside of the third generation frame of AIRDATA controllers, it appears as the complete and updated solution to the communication, monitorizing and work of units groups or installations in general. Based on the concept of computer network, it comes to substitute the traditional electrical interconnections with their high installation costs and limited work capacity (only stop/start signalings, and alarms). This new concept overcomes to the previous one in the following aspects: 1.- Very simple units interconnection. 2.- Monitorizing and remote work of all the parameters of any unit. 3.- Integration in computerized work systems. 4.- Robustness of the installation. 5.- Maintenance easiness. 6.- Enlargements at low cost. 7.- MIRAGE work software under platform WIN95, 98 (optional).

Basic module of communications SMART/485.
The interconectivity among the controllers, is achieved with the module addition of communications SMART/485, of a width 50mm and of the controller’s height, it is designed to be set up next to this in DIN rail and interconnected through the connector IDC (J2) type which both equipments incorporate. It incorporates the following elements: A. Slide switches, for the machine number configuration assigned in the installation. B. Feeding indicative Led. C. Two connectors RJ type for the connection in series of the network (J1,J3). Slide switches configuration for the machine number identification.
Communications module SMART/485
NOTE: For the network configuration a communication module is needed by each controller. The HSE/Smart sequencer is a natural evolution of the line of HSE sequencers, in totally updated version and based on microprocessor, adaptable to the connections bus of the Smart line denominated “Smart-Bus”. Indispensable in the cases in which a units sequence system is required. In the version 9.1, it is able to make the following functions: User Manual Control JT901/SMART Rev. 23.09.02

It has a physical configuration for traspanel assembly, in DIN rail and to be fed to the tension of the network of 230 VCA 50/60 Hz, and to maintain the clock in real time it has a battery type button which maintains this clock updated in feeding absence for a period of time non inferior to 6 months.While the sequencer is in low tension, this battery is not in use.
8.2.
Installation.
It can be installed next to the controller in any machine, and it is recommended that the feeding to the sequencer is independent of the machine that houses him, with the purpose of a possible failure of the machine feeding, the sequencer which manages the totality of the machines doesn’t run out of service. Note: The sequencers installed inside the electrical frame of an AIRDATA unit, will be disposed in the space given next to the IN/OUT card. The installer will have a feeding of 230V independent to the main assault of the unit. The bornes 103 and 104 to carry out this feeding.

Insert the network connection cable provided, in some of the connectors J3, J5. Insert the other extreme of the RJ cable in the controller or another network point. Feed electrically and allow some minutes for it to be auto-installed. Put in hour and day of the week from the control reading console, according to the procedure which is described next.
The sequencer once working, analyzes the number of machines and proceeds to adopt the starting algorithms, the sequence and the support by high room temperature in a totally automatic way.
8.2.2. Reading and Programming. Thanks to the reading console of any controller, it can by means of the “lower” and program the sequencer according to the following procedure: •
“-“ keys read and
Sequencer data reading
With the “lower” key and for every time it is pressed one will get an information of the machine number, the operation state (service, manual stop, stop by sequencer...), day of the week, hour and minute of the day, room temperature, etc. •
Sequencer programming
It is esential to introduce the “key” number to be able to access to the programming. In order to do this first press the “light” key and at the same time press the “M” key. Then the alphanumeric display will request the key number (*), introduce it and continuously press the “OK” key. Then it will allow us to enter in a sequencer programming submenu. (*) The key number can be requested from Airdata. A. B. C. D. E.
Press the “lower” key until in the display the word “sequencer” appears. Press the “OK” key. With the “lower” key advance the programming to the required parameter. Press “OK” and select the wanted data (date, hour, machine advance...). Accept with “OK”.
Programmable parameters: A. B. C. D. E. F.
8.3.
Machine manual advance. Machine simulation in support by temperature. Weekly sequence of machines. Fast sequence of machines (advance test every 30 seconds). Week day. Hour and minute.
Conversion module RS485/RS232 (optional).
It is one of the existing alternatives which allows the remote work of the units in network. For assembly next to the computer, it is useful to close the “Smart-Bus” knot and it gives the information from the network to the computer equipment. Therefore only one inverter will be needed for each local network knot. Having chosen this communications option and operation of the Airdata units, one should get in touch with Airdata if you want the Mirage software or the standard communication used to carry out this work. It is fed at 230 VCA 50/60 Hz and it has two RJ type connectors and a connector of two bornes for the braided connection, if you wish so close the knot. In the front of the equipment there are up to 3 leds of color green, red and yellow, as a recognition of low tension equipment, data emission activity and data reception activity.

Physically it has the appearance of the controller’s console JT801/SMART. The only visual difference is that in the visualization screen the unit we are visualizing and/or working appears (“M1” machine number 1). This module allows us to doble the controller’s funtions but from the distance. It is connected as the other modules which belong to the SMART/BUS having two connectors for this. Their handling is identical to a JT801/SMART console when visualising states and alarms. To change of visualized unit one will proceed to pressing the “bulb” and “OK” keys simultaneously. The console indicates the message “Machine number” with the digit of the unit visualised in that moment. With the “+”and ”-” keys one chooses the unit to work on. The programming functions can be carried out in an identical way as the console incorporated in the unit. For further information reading the controller’s manual JT801/SMART. Note: In special configurations this console allows the elimination of those included in the units, and monitorizing and working the units in al local way (up to 8 units) with one of them.

Configuration and connection.
Next it is detailed what one should do when configuring each unit and proceed to the connection of the SMART/BUS. All the operations due are to be carried out by qualified personnel who will have the responsability of the correct manipulation and maintenance of the installed system. In summary, these steps are divided in two fundamental parts. The first one is directed to the configuration of each one of the units in an independent way, to continue later with the general interconnection of all the elements which make up the SMART/BUS knots. The first task to carry out is to determine the units numeration which are included in the network. A network is defined by the units which are destined to acclimatize a room and its corresponding sequencer (in case of more than 1 unit and sequenced). To act as a remote interface one will be able to choose between the remote console or a 485/232 inverter or both systems in a simultaneous way.
9.1.
Previous configurations.
Once located the units in their definite position of operation, and having made the corresponding starting, the slip press buttons disposed in the module of adjacent network will be configured in the number of machines to the I/O JT801/SMART card.
Once the slip switches have been placed with the wanted numeration, it will be introduced through its incorporated console in the front panel the machine number assigned in the initial restating through the programming menu (see Mode 2).

Once each unit is made up will proceeded to interconnecting each one of them by means of the network wire available for this. It is advisable that the wire tracts which unite two distant points (more than 50 meters) are at least of category 5. Next we show an example of two units connection with sequencer, RS485/RS232 inverter and remote console. Once all the elements are connected it is necessary a recognition and connection establishment period between each one of them, which will be able to last between 2 and 3 minutes.
