GENERATOR CONTROL PANEL
OPERATION |
RUN MODES
There are three run mode options: Off, Manual and Auto. When the Manual pushbutton is pressed the unit will immediately start and the run indicator light will illuminate. In Manual mode, the generator will continue to run until the Off pushbutton is pressed to stop the unit. At this point the “not in auto” light will illuminate and the unit will not operate.
When the Auto pushbutton is pressed the unit will enter automatic run mode, where the generator controller and the transfer switch will control the operation of the unit. In automatic run mode, the unit will automatically start up and shut off when power failure occurs and to exercise the unit.
WARNING
•With the Mode in the Auto position, the unit starts and stops without notice.
•Keep clear of all moving parts at all times.
When power failure occurs, a signal will be sent to the generator to start a warm up cycle. After the warm up cycle is completed, the transfer switch will allow the load to be transferred to the generator until it senses that regular utility power has been restored. When this occurs, the transfer switch will remove the load from the generator and a signal will be sent to the generator to begin a cool down cycle. After the cool down cycle is completed, the unit will stop running, but remain in the automatic run mode.
The unit will also automatically start itself to ensure it remains in good working order. Every 28 days the unit will automatically start up without warning and run for 20 minutes before shutting down. The unit will remain in automatic run mode after each exercise session.
STARTING THE GENERATOR |
Two methods are available to start the generator. The automatic, or AUTO mode is for use with an automatic transfer switch. With the control panel mode switch set to this position, the generator waits for an external signal to start. This signal is supplied by the transfer switch when utility power is of unacceptable quality. Since utility power can fail at any time, be aware the generator can start unexpectedly whenever in the AUTO position. Keep away from moving parts at all times. Once utility power is once again acceptable, the signal from the transfer switch is removed, the generator shuts off, then returns to waiting for another signal to start.
The other method for starting the generating is to press the MANUAL position mode button. This mode is
intended for generator control during maintenance or if an automatic transfer switch is not used. With the control panel switch shifted to this position, the generator will immediately attempt to start after a brief pause. Upon starting, the generator runs until the switch is moved from the MANUAL position, at which time the generator will shut off.
CYCLIC CRANK |
To insure the generator starts without damaging the starter motor, cranking of the engine is performed in a cyclic manner. When the generator is started from either the AUTO or MANUAL positions, the controller alternates between 10 seconds of engine cranking, followed by 10 seconds of engine rest. If the engine starts during any of the cranking periods, crank attempts are halted and the controller begins monitoring for proper function of the generator. In the event that three 10 second start attempts occur without the engine starting, cranking attempts are halted and the Overcrank light is lit.
RUN STATE |
After the engine is started and the generator is producing electrical power, the controller begins operation in a monitoring state. In this state, several generator functions are continuously checked to ensure proper operation of the generator. If functions are determined unacceptable, a fault is declared, the engine is shut down and a status light is lit to communicate the reason for the shutdown.
SHUTDOWN |
When operating with the control panel switch in the MANUAL position, the generator will continue to run until a fault is declared or until the mode switch is moved to the OFF position. Once the switch is shifted to the OFF position, the engine is shut off.
When operating with the control panel switch in the AUTO position, the generator continues to run until a fault light is declared or the run signal is removed. Once the signal is removed, the engine shuts down and the controller returns to waiting for a start signal.
