1 Parameter settings introduction 1.1. Change of settings All settings can be easily set or changed directly with the front panel keys of HIMAP without any additional programming device or laptop computer. A menu tree structure offers easy access to the functions. To change a setting or to set new settings, first select the parameter with the updown keys (↑↓), and then press “ENTER.” The requested digit can be selected by using the leftright keys (←→). The digit can be changed by pressing the up-down keys (↑↓). After finishing the change of values (numbers) or text declaration, such as ON or OFF, press the “ENTER” key. The next parameter may now be selected by pressing the up-down keys (↑↓). 1.2. Event system introduction The event system of the device gives the user the possibility to realise his own applications. With events all functions of the device can be activated or deactivated. An event is a internal logical representation of a device process. The event system offers sources and sinks of events. The event sources have fixed unique event numbers. These event numbers became active (logically “True”) if the condition related to this event is fullfilled (e.g. a limit is reached), otherwise inactive (logically “False”). The event sinks are linked to fixed processes or fixed functions and can be programmed by the user. The user can build a link between the source and the sink by setting an event source number to an event sink number. The sink (function) became active if the related source became also active. Note: some modules are sinks and sources at the same time, e.g. all binary outputs are sinks and will be activated by source events. But every binary output produces himself again source events when he becomes active. The same is valid for alarms and all event builder elements. The source events can be combined over logic modules (event builder) which produces new source events. Examples: • The ANSI 25 /A Synchronizing unit 1 should be activated by a binary input (FUNC 20). The binary input is an event source and the Sync. unit is an event sink. The event number related to the input is 521. This number must be set on parameter 1000 (SYNC. UNIT 1 acitve by: 521) by the user. Then FUNC.20 activates the Sync. unit 1. • The ANSI 50 Overcurrent device should open a circuit breaker over a binary output (Shunt#1). ANSI 50 is an event source and the binary output an event sink (respectively a source). One event number related to ANSI 50 is 1402 (1.limit reached and delay passed). This number must be set on Shunt#1 (e.g. 01: 1402). Then a measured current value will open a circuit breaker.

OFF: If event of PM-switch is active, power management will be switched off. OFF -> ON: If event of PM-switch is active, power management will be switched on. [0902. START – check limits :] Checking single or average start limits. This parameter is valid for [0903], [0905] and [0909]. All limits can be disabled by setting them to zero. SINGLE: When passing limit parameters [0903], [0905] or [0909] the start order will be given depending on the load / current of each diesel engine. If a generator passes the limit while the others do not, a start order will be given. AVERAGE: Start order given if average load / current of Parameter [0903], [0905] or [0909] is passed. Average load / current means the average of load / current of all diesel engines running on the mains in one net.

– delay :] Delay time for current and load stop limit Parameters [0913] and [0914]. Note that both conditions must be fullfilled to start the delay. If only load stop is to be used, the current limit (914) must be set to zero. Both limits can be disabled by setting them to zero, if PMstop is not to be used. Current stop [914] is only available in connection with load stop, never alone. [0916. Stop without runn. down] If this parameter is set to “YES”, the stopped gen. will only open the CB (after load reduction), and than remain running. [0917. Block own start by event] By activating this event, the start of the own diesel engine through the power management system can be blocked. The blocking does not affect other start sources (e.g. blackout, start next…). A message will be displayed on the power management page if the blocking is active.
[2430. LOAD RANGES – by event] Event switch for the second power management function. This switch affects only the parameters 2431-2449. All devices in one net must have this switch enabled for activation! [2431. – change to upper range] If the actual net power changes from one range to a higher range, the higher range will be taken as the valid range after this delay time has passed. [2432. – change to lower range] If the actual net power changes from one range to a lower range, the lower range will be taken as the valid range after this delay time has passed. [2432. – load range hysteresis] This hysteresis is valid if the actual net power changes from one range to a higher range. The power must fall below this hysteresis in order to return to the previous (lower) range. [2434. – 1. load range] [2435. – priority] …… [2448. – 8. load range] [2449. – priority] With this parameters up to eight ranges can be defined. Each range starts at the previous range and ends at the setted kW value. For every range up to five gen. (identified in the net by the priorities) can be assigned, which should be connected to the bus bar. Note: the starting and stopping will begin when a new range becomes valid (after the delays P2431 or 2432 are passed). The system will first start all the needed generators. After all the needed generators are connected to the bus bar, the system will begin to stop the unnecessary generators. If one generator needed for the actual load range is not available (in MANUAL and stopped), the system will search for another generator with the same nominal power. If the search is without result, the next standby generator will be started. The stopping is blocked in this case. The system will start or stop only generators which priority is defined in one of the load ranges (parameters 2435-2449). The stopping is automatically blocked if the PM stop is blocked (see P912) or if a “big consumer request” is active in the net (see 2.10.7.). If parameter 2430 is setted to a value greater than zero, an supervision becomes active. This supervision checks if all the gen. defined within the parameters 2435-2449 are available (in AUTOM.). In this case event 2430 will be active. Event 2431 will be active if P2430 is set (to a value greater zero) and the gen. needed for the actual range are all in AUTOM. This events can be used for alarming or to control processes (e.g. to switch to the classical PM if gen. are not available).

The load controller parameters contain the settings for the request and the control and the release of big consumers within the same bus bar section. A maximum of four big consumers are managed by one device. After the request of a big consumer, the system checks the spinning reserve (valid load) of the corresponding net. Depending on the value of the spinning reserve, the load controller will start another diesel aggregate or release the big consumer directly. As long as the big consumer request is active, load depending stop of the power management will be blocked.

The load controller of the system operates in the following way. After a consumer request, the load controller evaluates the load of the bus bar section, in which the consumer has been requested. Depending on the load situation, the load controller will release the big consumer directly or after it has started one or more engines. The following parameter description refers to Big Consumer Request 1, since each consumer requests (1...4) or to have similar parameters with the exception of the event numbers. [0984. REQUEST 1 by event :] Request load-depending connection to Big Consumer 1. Select event number (normally a function input) and via it, enter request. The event must be active steadily until the big consumer has been switched on. Should the signal remain on at the input, diesel stop will be blocked. (Use for bow thruster operation.) [0985.
- requested load :] Enter power of Consumer 1. If there is sufficient reserve power, Event [0984] will be set without a delay. If there isn’t sufficient power, one or more diesel engines will be started. If after switching on the additional diesel engines, sufficient power becomes available, Event [0984] will be set after the load balancing delay time (set with Parameter [0189]). Event [0984] should be put on an output relay. If the power is not available, event 986 will be activated (for alarm).

Via an analogous input, the load state of the big consumer (actual load referring to nominal load) can be sent to the load controller. With this additional information, the load controller can reserve the required load at the bus bar. If the reserved load of the big consumer is higher than the valid load within the bas bar section, one or more engines will be started, if available. This additional function of the load controller works when the request event (Event [0984]) is active. Use one of the four analogous inputs of the basic unit of the system (CURR1…4). Example: If a 4…20mA input is selected, then an analogous signal of 4mA means that no power of the consumer is in use. 20mA means the total power of the consumer Parameter [0985] is in use.

[0230. BUS 1 – blackout by] Blackout 1 will be recognized if this event is active (e.g. function input). [0231. – mains monitor] Blackout recognition via mains monitor. The mains monitor supervises the Bus 1 voltage when this parameter is set to SINGLE or REDUNDANT. Redundancy means that all devices in one net must recognize the Bus 1 voltage limit. [0232. – voltage limit] If Parameter [0231] is enabled and one of the 3 lines of Bus 1 voltage is lower than the limit of Parameter [0232], then the mains monitor condition is fulfilled and Event [0232] will be set. [0233. – start delay] The delay will start if the blackout event condition [0230] or the mains monitor condition [0232] occurs. If the delay is passed, blackout Bus 1 start condition is fulfilled and Event [0233] will be set. [0234. – start diesel] The starting mode can be set by this parameter. All devices in one net should have this parameter set to the same value. There are several possibilities according to the mode: • ALL: all standby diesels will start and close their CBs. • NEXT: the first standby diesel will start. • OWN : the own diesel (if in standby) will start. • SEQUENCE: all standby diesels will start, but only the generator with the highest priority will close its CB. After that, the other generator will cancel the startphase and remain running. If the first generator fails to close its CB within 3 seconds, the generator with the next highest priority has the permission to close its CB.

Service Manual Note: if more than one generator is started (by any source) and no CB is closed in the net, a special interlock function becomes active. This function assures that only one generator at the same time has the permission to close the CB. The permission time is limited to 3 seconds. The other generator will remain waiting with blocked synchron -Events [1023],[1053],[1083]. [0235. [0236.
– stop enable by] – stop delay] The stop delay gets activated if Parameter [0235] is activated, the diesel is running, and Blackout 1 is inactive. If the delay is passed, and if Automatic has been selected, and if Event [243] is inactive, then the “own” diesel will be stopped.
[0237. BUS 2 – blackout by] Blackout 2 will be recognized if this event is active (e.g. function input). [0238. – mains monitor] Blackout recognition via mains monitor. The mains monitor supervises the Bus 2 voltage if Parameter [0238] is switched to ON. [0239. – voltage limit] If Parameter [0231] is activated and one of the three lines of Bus 2 voltage is lower than the limit of Parameter [0239], then the mains monitor condition will be fulfilled and Event [0239] will be set. [0240. – start delay] The delay will start if the Blackout Event Condition [0237] or the Mains Monitor Condition [0239] occurs. If the delay is over, Event [0240] will be set and the device will start the “own” diesel (if in standby). [0241. [0242.
– stop enable by] – stop delay] The stop delay gets activated if Event [0241] is activated, the diesel is running, and if Blackout 2 is inactive. If the delay is over and Automatic and [243] is inactive, the device will stop the “own” diesel.
[0243. STOP BUS 1,2 blocked by] The stopping of Blackout 1 or 2 can be blocked with this event. [0244. STOP preliminary output] The Event [0244] will be activated if the Delay [0236] or [0242] is passed and the stop is blocked by Event [0243] or manual mode. [0245. START BUS 1 blocked by] The starting of Blackout 1 can be blocked with this event. [0246. START BUS 2 blocked by] The starting of Blackout 2 can be blocked with this event. Note: For an automatic stop after blackout, it is advisable to use the Event [2957] (blackout start source) on Parameter [0235] or [0241], because the Event [2957] will be set on blackout start and will remain active until the engine is stopped by any source. For details related to the blackout function, refer to the logic on the next page.

[0260. Diesel control :] Main switch for diesel control. By setting this parameter to ON, the diesel control functions (starting and stopping of the aggregate) will be activated. [0261. SPEED - nominal :] Nominal speed of the engine. The nominal speed of the engine should be given in revolutions per minute (RPM). [0262.
- ignition :] Ignition speed limit. The ignition speed limit will be used within the starting phase to switch off the start valve when the speed signal exceeds this limit.
[0263.
- running up :] Running-up speed limit. The running-up speed limit will be used within the starting phase to recognize that the engine is ready to take load.
[0264.
- overspeed :] Overspeed limit. The overspeed limit can be used for the alarm system. This event number should be used to activate an alarm channel. [0265. TACHO - input :] Analogous input for speed measurement. If a tacho generator gives the speed signal of the engine, one of the four analogous inputs of the basic unit should be used. The adjustment setting of the analogous inputs is done within the parameter group “analog inputs” (see 2.5.).

Service Manual [0266. PICKUP - input :] [0267. - impuls /rev. :] Pick-up input for speed measurement. If a pick-up system provides the speed signal, set Parameter [0266] to ON. The number of impulses the pick-up system recognizes during one revolution has to be set with Parameter [0267]. If Parameter [0266] is set to IGNITION and at the pickup input is a high-signal, the device will take the limit from Parameter [0262] as the pickup speed value. [0268. LIMITS - n max. diff. :] The speed signal can be measured via three speed channels: tacho generator, pick-up system and via the generator voltage signal. Depending on which speed measuring system is active, the speed signals of the respective channel are compared among themselves. When the measured speed signal differs more than this limit, Event [0268] will be activated. Use this event number to activate a alarm (with delay). The following two parameters are speed limit events. These events will be activated when the speed signal fulfills the corresponding conditions. They can be used for alarming. [0269. - n high limit :] High speed limit. Event [0269] will be activated if the speed signal is higher then this limit. [0270. - n low limit :] Low speed limit. Event [0270] will be activated if the speed signal is lower then this limit. [0271. PRELUBRICATE -pulsetime:] [0272. -breaktime:] Prelubricating interval. For prelubricating the engine a pulse and a break time can be defined. During the prelubricating pulse time, Event [0271] is activated. This event has to be used to activate prelubrication via a function output. After the pulse time is passed, the break time will be started. Prelubrication works only in automatic mode. If the mode is started from manual to automatic, then prelubricating process will be introduced and started with the pulse time. The following events introduce the prelubrication process: [0273. Alarmblocking delay :] For diesel engines it is necessary to block some alarm channels which are related to engine warnings. The alarm blocking event 273 will be activated immediately when the speed signal falls below the ignition limit or the running down stopphase is active. If the speed signal reaches the ignition limit again, event 273 will be deactive after the setted delay is over.

The starting sequence includes a maximum of five phases (See also diagram starting procedure of diesel aggregate). 1. Preglowing time The first phase of the start procedure is used to preglow the engine. This phase can be shortened by an event. 2. Start time After pre-glowing the engine, the start time is activated. During this period the start valve will be activated to run up the engine. This phase can be shortened by reaching the ignition speed. After reaching the ignition speed, the start valve will be reset. 3. Running-up time The running-up time is a supervision time. If during this period the engine can not reach the running-up speed and minimum voltage limit, a fail event will be issued. 4. Ready-to-take-load time After reaching running-up conditions, the ready-to-take-load phase will be started. During this time the engine has to stabilize the speed before starting synchronization; or in case of blackout, the engine has to take the load immediately. 5. Synchronizing period During the synchronizing time, the speed and voltage controller try to synchronize the diesel generator to the bus bar. In case both systems are synchronized, the circuit breaker on command will be issued.

Service Manual [0630. PREGLOWING – max time :] Pre-glowing of the engine. This time defines the pre-glowing period of the engine. The starting phase of the aggregate begins with the pre-glowing period. After this period the starting valve will be set. If no pre-glowing time is required, the time should be set to zero. If the pre-glowing time is running, Event [0630] will be set by the system. This Event [0630] is used to activate a function output. [0631. – shorten by :] The pre-glowing period (See Parameter [0630]) can be interrupted by an event. If the event (defined with this parameter) is active, the pre-glowing period will be interrupted and the start valve will be activated. [0632. START VALVE – max trials :] Number of start attempts. If the engine speed is below the ignition limit, the start procedure will be separated into three phases.: 1. pre-glowing, 2. the start time (start valve) and, if the engine has not reached the ignition speed, 3.the break time. The number of starts to be attempted should be entered here. At the end of the last unsuccessful start attempt, a start fault event will be activated. Note: in MANUAL mode and by pressing the front key “START”, only one start trial will be executed. [0633. – fuel valve :] If a fuel oil valve is in use, this parameter has to set to “ON.” During start or operation of the diesel engine, this event number is always active. This event becomes inactive within the stopping phase or if the engine is stopped. E[262] n > ignition Startphase

Service Manual generator is run up if the speed signal is above the running-up limit Parameter [0263] and the voltage of the generator is higher than the minimum voltage of Parameter [0638]. [0639. READY TO TAKE LOAD time :] After the diesel generator reaches the run-up conditions (See Parameters [0637] and [0638]), the ready-to-take-load delay will operate. This time delay is used to stabilize the speed of the engine. After this delay time the next phase of the starting procedure will be introduced (e.g. switch on the synchronizing unit). [0640. SYNCHRONIZING max time * :] Synchronizing supervision time. If the diesel generator is ready to take load, event 640 will be activated. With this event one of the 3 synchronizing units can be activated. To supervise the synchronizing phase, a time limit can be entered. If after this time, the circuit breaker is not connected to the bus bar, a start failure will be issued. [0641. Start next after 1.trial :] After the first unsuccessful start attempt (See Parameter [0632]), the next available diesel engine of the same bus bar section will be started. [0642. Cancel if n > ignition :] With this parameter an additional condition for the startphase cancellation can be defined: • NO: cancel the startphase if the CB is closed. • YES: cancel the startphase if the CB is closed and if the speed reaches the ignition limit. [0643. Cancel start by event :] If this event is active, any start will be cancelled or blocked.

The stopping sequence includes at maximum four phases (See also diagram stopping procedure of diesel aggregate). 6. Alarm stop delay This phase will be used to start and connect another diesel aggregate to the bus bar before the engine is stopped. 7. Off with load reduction Within this phase, the load of the diesel generator is reduced with the speed lower signal. If the load is under a certain limit, the circuit breaker will be disconnected. 8. Running down phase The running-down phase is a supervision period. During this period, the speed of the engine is reduced via the stop valve output. If the speed signal does not fall below the ignition speed during that time, an alarm event will be issued. 9. Stop delay fixed time During the stop delay fixed time, the event for the stop valve will be set. This event is used to ensure that the engine reaches zero speed. [0650. Stop abort if last gen. :] Block stop order supervision. This parameter should be set to “YES,” if you want to block the stop order when the corresponding diesel generator is the last aggregate loading the bus bar. Stop orders introduced by alarms with any priority and the immediate stop order from the keyboard or by event [661] will stop the engine regardless of this parameter. [0651. ALARM DELAY – max time :] Stop delay time. If an alarm (see 1.3.) with priority 2, 6, 8 or 9 introduces a stop of the engine, the beginning of the stopping phase can be delayed with this delay time. This period of time is used to start and connect another diesel generator to the bus bar. The

Service Manual alarm delay maximum time can be shortened if another diesel generator is connected to the bus bar before this time has passed. [0652. LOAD REDUCT. – by event :] The load-reduction phase will be introduced automatically within the stopping phase. If another event activates the load-reduction function (e.g. off-switch at the front door of the cubical), then the event number should be set here. [0653. - loadlimit :] Load limit for load-reduction function. During the off with load reduction phase, the speed lower event will be set by the system until the load of the diesel generator is below this limit. Then the circuit breaker will be disconnected. [0654. – max time :] Maximum time for load-reduction phase. If the load-reduction phase is not finished within this supervision time, a failure event will be issued. [0655. – CB OFF ] Event for circuit breaker OFF command. This event number can be used to give out the circuit breaker OFF command. [0656. COOLING DOWN – time :] If the load-reduction phase is finished, the cooling down of the engine will be introduced. A period of time in which the engine should cool down with nominal speed should be entered here. [0657. – if alarm :] If an alarm with priority 2, 6 or 8 activates the stopping of the engine, the user can decide whether or not the cooling down period of the engine will also be activated. [0658. RUNNING DOWN – max time:] Running-down supervision time. A supervision period in which the speed of the engine should fall below the ignition speed limit while the stop valve is active should be entered here. [0659. FIXED DELAY - time :] Stop delay fixed time. If the speed signal is lower then the ignition speed limit, the stop delay fixed time starts. During this period the stop valve will be activated. [0660. Stop valve event ] Event number for stop valve. This event number is used to activate a function output that is connected to the stop valve (relay). [0661. Emergency stop by event ] If the event (e.g. a function input) becomes active, an emergency stop will be introduced. [0662. Stop interlock by event ] If the event (e.g. a function input) is active, all stop sources will be blocked (even alarm stops), with the exception of emergency stops by key or by Event [0661]. [0663. Cancel stop by event :] If this event is active, any stop (even emergency stops) will be cancelled or blocked.

Service Manual 3.3. ANSI 25 /A – Automatic Synchronizing Automatic synchronizing operates when two AC circuits are within the desired limits of frequency, phase angle and voltage range, allowing these two circuits to parallel one another. There are three automatic synchronizing units. Number 1 is responsible for the synchronization of the feeder bus to bus bar No.1; Number 2, of the feeder bus to bus bar No.2, and Number 3, between bus bar No.1 and bus bar No.2. The synchronizing units are laid out redundant. Two processor systems are responsible for the control and the supervision of the main breaker-on contact of the synchronizing unit. If HIMAP is used for ANSI 25 check synchronizing, only the following parameters are required for setup: Sync. Unit No. 1: 1000…1007 and 1023 Sync. Unit No. 2: 1030…1037 and 1053 Sync.

Service Manual The following parameter description corresponds to Synchronizing Unit 1 (feeder to bus bar 1). Synchronizing Units 2 and 3 have the same parameters and differ only in their parameter and event numbers. (See also description of synchronizing page within the users manual.) [1000. Sync. Unit 1 active by :] To activate the Synchronizing Unit No.1, an event number (e.g. binary input event) must be set. If this event number is active, the synchronizing window appears and the synchronizer with its frequency and voltage controller is operative. [1001. - MAX phase angle :] The maximum phase angle (positive and negative angle) appears in the window in which the closing order for the switching device (breaker) is given. [1002. - MAX frequency diff. :] If the difference of frequency is higher than the set point, then the synchron closing is blocked until the difference of frequency drops below the set point. [1003. - MIN frequency :] Minimum frequency limit for “abnormal bus” check. If the frequency of bus bar1 is below the minimum frequency limit, then the frequency controller will be deactivated. That means the output to send speed lower signals will be blocked. [1004. - MAX frequency :] Maximum frequency limit for “abnormal bus” check. If the frequency of bus bar1 is above the maximum frequency limit, then the frequency controller will be deactivated. That means the output to send speed higher signals will be blocked. [1005. - MAX voltage diff. :] If the difference in voltages is higher than the set point, the synchron closing will be blocked until the difference in voltages drops below the set point. [1006. - MIN voltage :] Minimum voltage limit for “abnormal bus” check. If the voltage of bus bar1 is below the minimum voltage limit, then the voltage controller will be deactivated. That means the output to send voltage lower signals will be blocked. [1007. - MAX voltage :] Maximum voltage limit for “abnormal bus” check. If the voltage of bus bar1 is above the maximum voltage limit, then the voltage controller will be deactivated. That means the output to send voltage higher signals will be blocked. [1008. - freq.set.pulse time :] The pulse time for frequency adjustment during synchronization is set here. The pulse time is defined at 100 percent frequency difference. The pulse time, which the frequency controller calculates after the break time, is modified by the difference between the two frequency inputs. The formula for the pulse is:
HYUNDAI HIMAP
HIMAP_ServiceManual_E.doc
- 75/149 -
Service Manual Calculation for pulse time: pulse [sec] = Parameter [1008] / 100 * ∆F [%] Whereby: Parameter [1008] : pulse time set point at 100% frequency difference. ∆F [%] : frequency difference between feeder and bus bar 1 in percent. Example:
Parameter [1008] = 100sec means: If the frequency difference between feeder and bus bar 1 is 100%, a pulse of 100 seconds will be set. If the frequency difference is 1% (0.5Hz at 50Hz nominal-rated frequency), then a pulse of 1 sec will be set, and so on.
[1009. - freq.set.break time :] The break time between pulse times for speed adjustment during synchronization is set here. After a break time is passed, the frequency controller will calculate the next pulse time to control the pulse event (Event 1008). [1010. - speed push after 10s :] If the difference between the electrical angles of the generator and bus bar does not become zero within 10 seconds, then an impulse of the set time in this parameter will be given. Note: instead of the speed push, the phase regulator can be used. [1011. - volt.set.pulse time :] The pulse time for voltage adjustment during synchronization is set here. Pulse time is modified by the difference between the voltages inputs. [1012. - volt.set.break time :] The break time between pulse times for voltage adjustment during synchronization is set here. [1013. - freq. higher event :] Use this event to activate a digital output in order to increase the frequency synchronization. [1014. - freq. lower event :] Use this event to activate a digital output in order to lower the frequency synchronization. [1015. - volt. higher event :] Use this event to activate a digital output in order to increase the voltage synchronization. [1016. - volt. lower event :] Use this event to activate a digital output in order to lower the voltage synchronization.

Service Manual [1017. – phase regu.active at] The phase regulation can be used to regulate the phase to zero if the two frequencies becomes nearly equal and the phase angle is nearly constant. If this parameter is set to 0 the phase regulator will be always inactive. Otherwise, if this parameter is set to a value > 0, the speed push (P1010) will be always inactive, and the phase regulator will be activated in the following way: if the difference between the two frequencies reaches this low limit (P1017), the phase regulator becomes active. The regulator will remain active until the difference exceeds the “MAX frequency diff.” (P1002). [1018. – phase 360 deg pulse ] The pulse time for phase regulation is set here. The pulse time, which the phase regulator calculates after the break time (P1009), is modified by the actual phase angle. The formula for the pulse is: pulse [sec] = (Parameter [1018] * deg) / 360. [1019. - closing direction :] The main breaker closing command will be given only when the engine speed is higher (UP), lower (DOWN) or in both directions. See also figure 25-5 and 25-6. [1020. - CB closing delay :] The main breaker closing delay is the mechanical delay time caused by the closing time of contactors, relays and the main breaker itself. This delay time can reduce the time period of “breaker synchron on command” Event 1023). [1021. - live/dead cond. check :] ON/OFF-switch for dead condition check. If the synchronizing unit recognizes one side (feeder or bus bar) without voltage (dead system), then the Event 1023 (CB sync.ON) will be activated without checking synchronization. Note: if HIMAP- XG/BCG is selected, only the bus bar will be checked for live/dead condition. [1022.
- min. voltage level :] If the live/dead condition check (Event 1021) is active and the voltage of one side (feeder or bus bar) is below this voltage limit, the synchronizing unit recognizes dead condition.
[1023. - CB sync. ON event ] Use this event to send the main breaker close signal. This event will be set if the pointer of the synchronization unit is within the synchron window and the synchronization unit is not blocked. [1024. - abnormal bus 1 event ] Use this event to indicate bus abnormal situation. If during synchronization the main conditions for voltage and frequency are not fulfilled for the bus bar, then bus abnormal event will be set and the corresponding controller for voltage and frequency will be blocked. (See Parameters 1003, 1004, 1006, 1007).

Service Manual 3.20. ANSI 64 / 59N – Overvoltage ground relay
Ground detector relay is a relay that operates on failure of machine or other apparatus insulation to ground. Sensitive ground fault detection may be used in isolated or compensated systems to detect ground faults. In solidly or low-resistance grounded systems, sensitive ground fault detection is used to detect high impedance ground faults. Sensitive ground fault detection may be used for alarming and acoustic signaling, or may be allowed to initiate tripping. Programmable timers are supplied to supervise the alarming and tripping. For this protection function, HIMAP must be equipped with a sensitive input transformer. Because of its high sensitivity, ground fault detection is not suited for detection of high magnitude ground faults. The directional and nondirectional overcurrent protection functions are preferred for this application.

Service Manual 3.22. ANSI 67 – AC directional overcurrent relay
AC directional overcurrent relay is a relay that functions on a desired value of AC overcurrent flowing in a predetermined direction. When the directional overcurrent stage exceeds the current setting (Parameter [1801]) and if the directional operation has been selected, then the directional criteria should activate Event [1801]. After the time delay, Event [1802] will be activated. These events can be used to activate the alarm controller and the binary outputs. The operation of the directional overcurrent stage is based on a definite time or inverse time characteristic. This mode of operation is set with Parameter [1803]. At definite time mode of operation, the operating time is set in 10msec steps. At inverse time mode of operation (I.D.M.T.), six internally standardized and two special type time/current characteristics are available. The operation stage starts if the current on one of the phases exceeds the setting value and if the phase angle between the current and base angle falls within the operation sector +/- 60° if the phase angle is selected at Parameter [1807]. The directional control is based on measuring the phase current and the phase voltage. The phase voltage is recalculated from the line voltage, which means that earth influences at the phase voltage are eliminated. HIMAP parameters: ANSI 67 AC directional overcurrent 1800. 1801. 1802. 1803. 1804. 1805. 1806. 1807. 1808.

Service Manual 3.26. ANSI 79 – AC reclosing relay
AC reclosing relay is a relay that controls the automatic reclosing and locking out of an AC circuit breaker. From experience, the majority of faults associated with overhead distribution feeders are temporary in nature. Therefore, to maximize service availability, it is desirable to employ a system that will close the circuit breaker shortly after it is tripped. This is accomplished in the HIMAP via the automatic reclosing system. When the automatic reclosing system is used, if the fault still exists after the circuit breaker has been reclosed, then the protective elements will retrip the circuit breaker. Depending on the number of reclosing attempts programmed for the automatic reclosing system (up to nine are possible), the circuit breaker will either be reclosed again, or it will remain open. The automatic reclosing function is typically utilized only in situations in which the occurrence of temporary faults is anticipated. Therefore, the automatic reclosing system is not applied when the HIMAP is used to protect generators, motors, transformers, and cables. The automatic reclosing function can also be initiated by an external protection relay. For this application, an output contact from the tripping relay must be wired to a binary input of the HIMAP. It is also possible to allow the HIMAP to work in conjunction with an external reclosing device. Initiation of the automatic reclosing function can be caused by internal protective functions or externally using a binary input. Each of the following elements may initiate the automatic reclosing function: ANSI 50-1, 50-2, 50-r, 51, 46-1, 46-2, 46-TOC The automatic reclosing system can be programmed so that any of the elements above can initiate, not initiate, or block reclosing. If an element initiates reclosing, the appropriate reclosing program is executed. HIMAP parameters: Permissible setting range:

Service Manual 3.27. ANSI 81 – Frequency relay
Frequency relay is a relay that responds to the frequency of an electrical quantity and operates when the frequency or rate of change of frequency exceeds or is less than a predetermined value. The frequency is measured from the feeder voltage. The frequency protection function detects abnormally high and low frequencies in the system. If the frequency lies outside the allowable range, appropriate actions are initiated, such as load shedding or separating a generator from the system. A decrease in system frequency occurs when the system experiences an increase in the real power demand, or when a malfunction occurs with a generator governor or automatic generation control (AGC) system. An increase in system frequency occurs when large blocks of load are removed from the system, or again when a malfunction occurs with a generator governor or AGC system. Through the use of filters and repeated measurements, the frequency evaluation is free from harmonic influences and very accurate. Frequency protection consists of four frequency elements. Two given frequency element can be set to pickup for overfrequency and two for underfrequency conditions. Each element can be independently set, and utilized to perform different functions within the system. The frequency can be determined as long as the positive sequence voltages are present and of sufficient magnitude. If the measurement voltage drops below a settable value, Parameter [2012], then frequency protection is blocked. For elements used in an underfrequency protection mode, as soon as the frequency of the measured voltage decreases below the setting, the element picks up and remains picked up until the system frequency increases above the setting. For elements used in an overfrequency protection mode, as soon as the frequency of the measured voltage increases above the setting, the element picks up and remains picked up until the frequency decreases below the setting.

Service Manual 3.33. ANSI 95i – Inrush blocking relay When the SYMAP® is installed to protect a power transformer, large magnetizing inrush currents will flow when the transformer is energized. These inrush currents may be several times the nominal transformer current, and, depending on the transformer size and design, may last from several milliseconds to several seconds. Although pickup of the relay elements is based only on the fundamental harmonic component of the measured currents, false device pickup due to inrush is still a potential problem since, depending on the transformer size and design, the fundamental harmonic comprises a large component of the inrush current. The SYMAP® features an integrated inrush restraint function that may be utilized when the device is installed at or near a transformer. It supervises the “normal” tripping of all directional and non-directional overcurrent relay elements with the exception of the ANSI67 and ANSI67GSGD relay elements. For example, when a transformer is energized the current levels may exceed the normal pickup of the overcurrent elements set in the device. If inrush conditions are identified (the 2nd harmonic content of current exceeds the value of setting at Parameter 2302), special inrush messages are created within the device that will block tripping of the overcurrent elements. Note, that only the tripping elements are affected by harmonic inrush detection, the pickup values and corresponding timers continue to operate normally. Inrush current contains a relatively large second harmonic component which is nearly absent during a short-circuit fault. Inrush current detection, therefore, is based on the evaluation of the second harmonic component present during inrush conditions. For frequency analysis, digital filters are used to conduct a Fourier analysis of all three phase currents and the ground current. As soon as the second harmonic component of the current flowing in a specific phase or ground relay element exceeds a set value, tripping is blocked for that element (does not apply ANSI67, and ANSI67GSGD elements). Since quantitative analysis of the harmonic components of the current flowing through a specific relay element cannot be completed until a full cycle of inrush current has been measured, inrush restraint blocking, and the associated inrush detection message, is automatically delayed by one cycle. It is important to note, however, that the tripping time delays associated with the relay elements are started immediately after pickup of the relay element, even if the inrush conditions are detected. If inrush blocking drops out during the time delay, tripping will occur when the time delay of the element elapses. If inrush blocking drops out after the time delay has elapsed, tripping will occur immediately. Therefore, utilization of the inrush restraint feature will not result in any additional tripping delays. If a relay element drops out during inrush blocking, the associated time delay will reset.

Service Manual [1. and 2. group] Each alarm channel can be assigned to one or two alarm groups. If one of the alarms belonging to this group is active, the corresponding group event will also be activated. A maximum of twenty alarm groups (80-99) can be created. [priority] Note: only for HIMAP XG/BCG (power management) Through the priority settings, useful attributes can be set to the corresponding alarm channels. Additional operations such as “change to manual mode,” “start the next diesel” or “stop own aggregate” will activated after the alarm appears. The following table shows all alarm priorities and the corresponding operations that are activated after appearance of the alarm.

[option] (not in use yet) [beeper] • OFF: No sound when the alarm appears. • ON: When the alarm appears, the beeper will be active until the ACK key is pressed. Note: There is a special beeper Event [2918], which can be used to drive external signal devices over an binary output. [LED CONTROL] The LED control box defines the action of the alarm LEDs if the alarm occurs: • ALARM: the main alarm LED will be activated. • TRIP: the trip LED will be activated. • red, amber, green (only HIMAP BC/BCG): the multi-colored LEDs left side of the LCD screen (where the alarm text is shown) will be activated. If more than one color is marked, the LED will blink alternately in these colors.

LATCHED
Alarm output Beeper Acknowledgement
The “alarm trigger event” is the event number which activates the alarm channel. The “alarm channel event” will be active as long as the alarm is acknowledged. If the “alarm channel event ” is linked to a binary output, this output will be activated in accordance to the “latched/unlatched” condition set within the alarm channel settings. The “beeper” will be activated by the “alarm trigger event” and reset after alarm acknowledgement. Note: There is a special event [2936], which becomes active if a new alarm occurs. After that this event can be reset with ACK.

[0074. Deadband filter] This parameter is valid for all measure data which are outputted over the LCD, the analogous outputs and which are transferred through all communication ports. If any value falls below the setted deadband limit, the value will be reset to zero. Furthermore, if the changing of any value is below the deadband limit, the average builder (parameter 111, see chapter 2.2.) will plane the value. [0075. Frequency filter] This parameter filters the Gen., Bus 1 and 2 frequencys. Only frequency changes below the setted value (in mHz/sec) are accepted by the measuring system. [0090. FILTER -RPM nominal/dt] Note: only for HIMAP XG/BCG (power management) With this parameter the measuring system builds an average of the diesel speed. [0091. FILTER – analog inputs] With this parameter the measuring system builds an average of the analog inputs values, except the PT 100 inputs (see 2.5.). [0092. FILTER –PT 100] With this parameter the measuring system builds an average of the PT100 inputs (see 2.5.1.).

Service Manual [0055. Wirefault limit] If the measured LSB value of a binary input falls below this limit, wirefault is detected (see 2.6.). [0084. Oscillation limit] If the changings of a binary input per seconds exceeds this limit, system fail 3012 will be activated (see Appendix A2). [0054. SERIAL PORT 1 - Stopbits] With this parameter the number of stopbits (1 or 2) in the transfered bytes through serial port 1 can be adjust (see 2.4.). [0057. Modbus FC3 Byte count] With this parameter the number of bytes (1 or 2) of the byte count field in function code 3 of the Modbus protocol can be adjust (see Appendix A1). [0078. Select breaker mode] With this parameter the operating (breaker) modes for the device can be selected (see chapter 2.5. in the Users manual). The following modes are available: • none: no modes selected. This can be used for HIMAP XG/BCG, because for Power management usually only the AUTO/MANU. modes are used. • Loc/Rem: the valid modes are “Local” and “Remote”. • Test: the valid modes are “Local”, “Remote”, “Test Local” and “Test Remote”. [0088. Change to TEST mode] If this parameter is setted to AUTOM. and parameter 78 to “Test” the device will switch automatically to the test mode (“Test Local” or “Test Remote”) if one breaker changes the position from IN->OUT (see chapter 2.5. in the Users manual). [0060. Current direction (gen.)] This parameter defines the direction of the generator current. [0082. Select extension board] This parameter enables the software for various extension boards. [0058. Analog input 4 – additional low limit] With this parameter the user has the possibility to set an additional low limit for analog input 4 (see chapter 2.5.). The limit is disabled if the setted value equals zero. If the value reaches this low limit, event 2935 will be set. [0032. Uaux CAL.] This parameter calibrates the Uaux measure input (see chapter 3.32.). [0033. Shunt1 CAL.] This parameter calibrates the Shunt 1 measure input (see chapter 3.32.). [0034. Shunt2 CAL.] This parameter calibrates the Shunt 2 measure input (see chapter 3.32.).
