After the starter motor has disengaged, the Safety On timer is activated, allowing Oil Pressure, High Engine Temperature, Under-speed, Charge Fail and any delayed Auxiliary fault inputs to stabilise without triggering the fault. Otherwise, the Warm Up timer, if selected, is initiated, allowing the engine to stabilise. After the Warm-up timer has expired then the module will close the load switching device. The generator will then supply the requirements of the load.
For added security, the modules also monitor the bus. If this is found to be live, then the synchronisation process begins. Once the load switching device is closed, the will then ramp to share the load with the other generators in the system.
This prevents excessive wear on the engine. When the Remote start signal is removed, the Stop delay timer is initiated. Once this has expired, the module will ramp the load from the generator to remaining set Multi-set systems only. Once the Cooling timer expires, the Fuel Solenoid is de-energised, bringing the generator to a stop. Should the Remote Start signal be re-activated during the cooling down period, the set will return on load.
NOTE:- When synchronising is enabled, the bus is checked before closing any load switching device. If the bus is live, synchronising will take place before any closure takes place. NOTE:- Synchronising can be disabled if the application does not require this function. Contact your genset supplier in the first instance for further details. Please refer to the 5xxx Configuration Software manuals for full details on the feature.
Manual mode is used to allow the operator to control the operation of the generator, and to provide fault finding and diagnostic testing of the various operations normally performed during Automatic mode operation.
Viewing the instruments and event logs i is NOT affected by panel lock. An LED besides the button will illuminate to confirm this operation.
If the pre-heat output option has been selected, this timer will be initiated and the auxiliary output selected energised. After the above delay, the Fuel Solenoid or ECU output if configured is energised, and then one second later, the Starter Motor is engaged.
Should this sequence continue beyond the set number of attempts, the start sequence will be terminated and Fail to Start will be displayed. When the engine fires, the starter motor is disengaged and locked out at a pre-set frequency measured from the Alternator output. Rising oil pressure can also be used to disconnect the starter motor; however, it cannot be used for underspeed or overspeed detection.
Once the engine is running, the Warm Up timer if selected is initiated, allowing the engine to stabilise before it can be loaded. Once the warm up timer has expired the generator is then available to go on load and the Generator Available LED will illuminate on the front panel. A Remote Start on load signal is applied 2. An on-load run is configured in the scheduler. The Close Generator button is pressed. During the parallel run the module can be configured to either run at a fixed level output, such as when used in parallel with an infinite bus.
Alternatively, it can be configured to load share with other generators on the bus. If Auto mode is selected and the remote start on load signal not active, and the scheduler is not calling for a run, then the Return Delay Timer will start. Once this has expired then the module will exit parallel operation and will ramp the load back to the remaining generators.
The generator will then run off load allowing the engine a cooling period. This operation may lead to loss of supply to the load. NOTE: - Synchronising can be disabled if the application does not require this function.
NOTE: - When synchronising is enabled, the bus is checked before closing any load switching device. NOTE:- Upon closing the load switching device, the module checks that the bus becomes live.
If it does not, an alarm is generated to indicate the problem. Alarm Warning The type of alarm. Shutdown or warning Low oil pressure The nature of alarm, e. Low oil pressure. The LCD will display multiple alarms e. These will automatically scroll round in the order that they occurred. In the event of a warning alarm the LCD will display the appropriate text.
If a shutdown then occurs the module will again display the appropriate text. The unit will scroll through all active alarms in a continuous loop.
Warnings are non-critical alarm conditions and do not affect the operation of the generator system. In the event of an alarm the LCD will jump to the alarms page and scroll through all active warnings and shutdowns. Alarm Warning Low Coolant Temp will be displayed. Alarm Warning High Current will be displayed. If this high current condition continues for an excess period of time, then the alarm is escalated to a shutdown condition.
For further details of the high current alarm, please see High Current Shutdown Alarm. If the feedback does not confirm the action within the Generator breaker open timer, then the following alarm will occur. Should either of these values exceed the pre-set service interval the following alarm will occur.
Incorrect wiring type or connection may be a possibility. This may indicate a break in the MSC connection between the sets. The engine inlet temperature electronic engines only is above the level of the Engine Inlet Temperature alarm. This can indicate a problem with the setup or control of the AVR. For instance, if the engine temperature rises past the pre alarm level, a warning condition will occur to notify the operator.
If the temperature falls below this level, then the alarm ceases and the set will continue to run as normal. However if the temperature continues to rise until the coolant temperature trip point is reached, the warning is escalated and a high coolant temperature shutdown is initiated. Alarm Warning Low Oil Pressure will be displayed. Alarm Warning High Coolant Temperature will be displayed. Alarm Warning Overspeed will be displayed.
It is an immediate warning. Alarm Warning Underspeed will be displayed. Should this exceed a pre-set amount of negative Var this indicates a possible loss of excitation on the alternator. The following alarm will then be generated. Alarm Warning High frequency will be displayed, it is an immediate warning. Alarm Warning Low Frequency will be displayed. Alarm Warning High voltage will be displayed, it is an immediate warning. Alarm Warning Low Voltage will be displayed.
The alarm must be cleared and the fault removed to reset the module. NOTE:- The alarm condition must be rectified before a reset will take place. Alarm Shutdown Fail To Start will be displayed. Alarm Shutdown Low Oil Pressure will be displayed. Alarm Shutdown High Engine Temperature will be displayed. Alarm Shutdown Overspeed will be displayed. Overspeed is not delayed, it is an immediate shutdown.
NOTE:-During the start-up sequence the overspeed trip logic can be configured to allow an extra trip level margin. Alarm Shutdown Underspeed will be displayed. Alarm Shutdown High Frequency will be displayed, it is an immediate shutdown. Alarm Shutdown Low Frequency will be displayed. Alarm Shutdown High Volts will be displayed, it is an immediate shutdown. Alarm Shutdown Low Volts will be displayed.
This is to prevent nuisance tripping when applying or removing load on the generator. Alarm Shutdown Sender Fault will be displayed. Sender failure is not delayed, it is an immediate shutdown.
MPU failure is not delayed, it is an immediate shutdown. Alarm Shutdown Loss of Speed Signal will be displayed. NOTE:- This will only occur if the magnetic pickup speed sensing signal is lost during cranking or during the safety on timer. If the signal is lost during normal operation the Generator will shutdown with an Under-speed alarm. Please contact the engine manufacturer for further assistance.
The above displays show a standard J based system. Other manufacturers systems supported by the module work in a similar way though the exact detail may vary from those illustrated.
This alarm is configurable between Warning, Shutdown and Electrical Trip. On modules prior to version 5. Should this exceed a pre-set amount of negative VAr this indicates a possible loss of excitation on the alternator.
Electrical trips are latching and stop the Generator but in a controlled manner. Once this has occurred the module will start the Cooling timer and allow the engine to cool off-load before shutting down the engine. The alarm must be accepted and cleared and the fault removed to reset the module. The following alarms are configurable between Warning, Shutdown and Electrical Trip.
This warning will continue for a period of time depending upon the level of overload that the generator is subjected to and the configuration setting for Generator High Current in the 5xxx series configuration software. If the load level does not drop to normal levels within one hour, the breaker is opened and the set is cooled down and stopped. NOTE:- Higher overload levels will result in a faster acting shutdown condition. For details of the relationship between the overload and the shutdown time, please see the Appendix section of this manual.
This is included within the module and will detect failure of the mains supply during parallel operation with the generator. NOTE:- This protection operates only when in parallel with the mains supply and is disabled at all other times. Should either of these alarms operate, the module will perform a controlled shutdown electrical trip of the generator. This operation must be manually reset :.
The engine will stop if it is still running and the alarm is cleared. Status Indicates that the module is in Automatic and that the system is in standby. The unit will respond to an active remote start signal. Waiting in Auto. Status Indicates that the module is in automatic and that a start sequence has been initiated, by remote start input.
The module is attempting Cranking attempt to crank the generator. L-L v The generator is not shutdown. Warning Low oil pressure. Alarm The oil pressure has fallen below a second pre set value and has shutdown the generator.
Shutdown Low oil pressure. Alarm The module is warning that the battery voltage is below a pre set value. Warning Low battery Volts. Event log 1 On the 17th January at the unit detected a Engine High temperature condition. Event log 2 On the 8th September at The emergency stop button was pressed and the generator was shutdown. Event log 3 On the 7th September at , the unit detected that the generator output volts exceeded pre-set trip level and has shutdown 7 Sep the generator.
Over Volts Shutdown. The LCD will display the page title and then will automatically commence scrolling down the various instruments. On reaching the last instrument, the LCD display will then jump back to the page title and resume scrolling down the page.
This sequence will be repeated until either the user moves off the page, the LCD page timer has expired or an alarm condition occurs. In the case of the latter, the module will jump to the alarm page to show the relevant alarm details. It is also possible to scroll to display the different instruments using and buttons. NOTE:-This description of operation is also true for the other instrument pages and for viewing the records in the event log.
NOTE:- The factory default setting is to show all instruments in a single list. When configured to the page style, the instruments are grouped into separate pages — i. Engine instruments, Gen instruments, bus instruments. The moving bar will roll from one side to the other showing the phase of the two supplies. The area in the centre of the scope indicates the set limits for synchronising to occur.
Synchronising will only occur when both the Frequency and the voltage differences are within Hz Then the moving bar display will show the phase difference.
The engine speed will be automatically adjusted, altering the phase, until the moving bar enters the centre of the scope. Once the Mains and generator supplies are synchronised, the module will initiate a breaker close Hz Should synchronism be broken the moving bar will pass out of the synchronising window.
Note:-At the start of the synchronising process and if the display is still on the status page, the module will automatically switch to the Synchroscope page. Once the system enters one of the ramping states, the ramp progress will also be displayed on the screen. For instance, this will occur if the breaker is manually opened, or tripped by a device external to the controller. Engine oil temperature Coolant pressure Inlet manifold temperature Exhaust temperature Turbo pressure Fuel pressure Fuel consumption Total fuel used.
The configuration editor contains two sections.
