RUNNING MODES Automatic Mode: If you press automatic button marked A genset will switch to automatic mode. In this mode panel controls mains voltages and if mains is outside the limits that you programmed, Panel will open the mains contactor and starts the genset. After engine stabilization time and generator contactor delay load transferred to the generator. Panel controls all the engine values to detect possible failures after engine stabilization time. If mains come to normal condition, mains is controlled during mains return delay for stabilization. If mains is normal after mains return delay, generator contactor opens and mains contactor closes. Genset is stopped after cooling period. In automatic mode, if panel is in engine off state and detects an engine running signal. Panel will stop the engine. Test Mode: If you press test button at the right side of front panel. Genset will be switched to test mode. In test mode engine starts immediately. After engine stabilization time if parameter test mode is test off load genset wait for mains failure in running condition. When mains failure occur mains contactor opens and generator contactor closes. In same way when mains returns, panel waits mains return delay and switch back to mains. If parameter test mode is test on load. After engine starting, generator contactor closes and genset supply the 7 8 load. If operator wants to stop the engine in test mode panel must be returned to automatic or manual mode. In manual mode you can stop the engine by stop button. In manual mode all start stop and preheat operations, contactor control fulfilled by panel buttons. PANEL RUNNING PHASES 1. Generator is still: In this condition engine running signals must be absent. These are oil pressure, charging alternator warning lamp signal, generator voltage and frequency. In manual mode panel doesn t react to this signal but in automatic mode panel will try to stop engine. If electricity panel of genset has manual control and these are wanted to be used. Electronic panel must be switched to manual mode. 2. Preheating: In cold weathers preheating of engine can be necessary. Engine must be still during preheating. If parameter preheating time is not zero, preheating is accomplished before starting process by panel. 3. Cranking: In this stage engine is cranking. All engine signals must be absent and engine must be still before cranking. If one of the engine signal is detected before cranking, panel switch to start and stop alarm. Panel will show which signal is detected with engine start stop alarm. If oil pressure signal is detected before cranking panel will wait for it to decrease to zero. If before cranking oil pressure delay is elapsed and oil pressure is not zero panel will switch to start and stop alarm. In cranking stage all engine signals, alternator frequency, alternator voltage, charge alternator voltage and oil pressure is controlled. If one of the signals is detected, Panel detects engine is running, crank disconnects and switch to engine stabilization time. Generator status led starts to blink. During cranking, Str message is shown in the display. Oil pressure can rise before engine running so when oil pressure is detected, crank disconnected after crank disconnect oil pressure delay. 4. Stabilization: After generator running signals detected panel waits for engine signals to stabilize. After engine stabilization time, all alarms are activated. 5. Running: After stabilization time genset is in running condition. If genset in manual and test modes, alternator contactor time is waited and alternator contactor is closed. In manual mode operator can close the generator contactor by generator contactor button. In running mode generator status led is lit. 6. Cooling: If a stop condition occurs by operator or mains status. Generator is switched to cooling period and engine is cooled during cooling time. During this time engine status led is blinking. If alternator contactor hasn t been closed since last start cooling period is bypassed. If mains failure occurs during cooling process generator is switched back to running mode and alternator contactor is closed. After cooling process generator is switched to stopping condition. 7. Stopping: After cooling stage, generator switches to stopping stage. If fueling system is operating solenoid, operating solenoid is de-energized. If fueling system is stop solenoid solenoid energizes until engine stops. If one of the engine running signals is detected stopping period doesn t ends. Alternator frequency and voltage, charge alternator warning lamp signal and oil pressure must be absent. If panel detects engine signals after fail to stop delay panel will switch to start stop alarm. 8. Generator shutdown: Generator is stopped because of a red alarm. Generator cannot be started if alarm is not cleared. 8 9 ALARMS Alarms are divided to red and yellow alarms. Yellow alarms are for warning purposes and don t stop the generator. Red alarms are serious and if occur generator contactor is opened and generator is stopped immediately. High and low speed (RED ALARM): If alternator frequency is higher than generator over frequency failure or is lower than generator under frequency failure panel switches to this alarm. Alarm is activated after generator frequency failure delay. High and low alternator voltage (RED ALARM): If alternator voltage is higher than generator over voltage failure or is lower than generator under voltage failure panel switches to this alarm. Alarm is activated after generator voltage failure delay High coolant temperature (RED ALARM): If temperature that is read from temperature sender is higher than high coolant temperature level or if temperature switch sends alarm to panel. Panel switches to high coolant temperature alarm. Over current failure (RED ALARM): If currents values read from current transformers is higher than over current level. Generator contactor is opened and generator switches to cooling. After cooling stage generator stops. Alarm is activated if condition continues for over current alarm delay Periodic service: When periodic service time elapsed after last periodic service. Alarm is displayed. Only service personnel can reset alarm. Fail to start stop: If this alarm occurs that means panel couldn t start or stop engine. If one of the engine signals is detected, before cranking, panel switch to start and stop alarm. In automatic and test modes if generator couldn t be started after user defined crank attempts, panel switches to fail to start stop alarm. In engine stopping stage if panel still detects engine signals after fail to stop delay. Panel switches to fail to start stop alarm. Alarm led lamps indicates which engine signal is still present and causes fail to start stop alarm. Low oil pressure (RED ALARM): If oil pressure that is read from oil pressure sender is lower than low oil pressure level or if oil pressure switch sends alarm to panel. Panel switches to low oil pressure alarm. Charge Failure (YELLOW ALARM): If charge voltage read from charge alternator warning lamb terminal decreases, panel switches to this alarm. This alarm doesn t stop generator. V AUX. Battery high and low voltage (YELLOW ALARM): If battery voltage is higher than battery high alarm level or is lower than battery low alarm level panel switches to this alarm. This alarm doesn t stops engine. Auxiliary input (YELLOW or RED ALARM): When an auxiliary input alarm occur. This led is lit and A1, A2, A3 or A4 message is written to display. A1 means auxiliary input1 alarm. 9 10 Mains failure: If mains voltage is lower than mains under voltage failure or is higher than mains over voltage failure mains failure occur and in automatic mode generator is started. If mains comes to normal condition (higher than under voltage return and lower than over voltage return ) generator is stopped in automatic condition. Emergency stop: If auxiliary input is adjusted for emergency stop and user presses emergency stop button. StP message is shown in the display, generator contactor opens and engine stops immediately. To clear this alarm user must pull emergency stop button and clear the alarm. Sensor failure: If cable connected to sender terminal of oil pressure and temperature senders breaks. Sensor failure alarm is given. For oil pressure sender osn message and for coolant temperature sender tsn message is shown in the display. Alarm is activated if condition continues for 4 seconds. If analog oil pressure sender usage and analog coolant temperature sender usage parameters are set to 0, sender will be used for display purposes and no alarm is given in sensor failure condition. EEProm Failure: When this alarm occurs EEP message is written to display and you must call service. Genset mustn t be started.
