Table 1 CONTROL POSITION/SELECTION ACTION "DROOP-ISOCHRONOUS" switch "ISOCHRONOUS" Engine speed does not drop when a load is applied. "IDLE"/"RATED" switch "RATED" Moves engine from "IDLE" speed to "RATED" speed. Circuit breaker switch "NAC" (1) This enables the generator circuit breaker to be closed. Lockout relay "RESET" Removes the disabling (lockout) voltage from the switchgear. "LOCAL"/"REMOTE" setpoint Not used None "START/LOAD" on the "MAIN" screen Not used None "STOP/UNLOAD" on the "MAIN" screen Not used None "SYNCHRONIZING" switch "ON" Turns the synchronizing lights ON. Enables the closure circuit for the generator circuit breaker. Engine control switch "MANUAL" Puts the switchgear in "MANUAL" mode. The engine is started. Alarm switch Not used None Manual load potentiometer Not used None VAR/Power factor adjust potentiometer Used Adjust as needed in order to regulate the power factor of the genset. "BASE LOAD START" (Remote) No contact None "BASE LOAD STOP" (Remote) No contact None "STANDBY START" (Remote) No contact None "STANDBY STOP" (Remote) No contact None Show/hide table( 1 ) Turn the handle of the circuit breaker switch to the fully clockwise position. Release the handle. The handle will return to the center position. The red target will be visible.
- Place the engine control switch in the "MANUAL START" position.
Note: The genset will perform these operations:
- Start
- Go to rated speed
- Go to rated voltage
Monitor the "SYNCHRONIZING" lights. When both lights are OFF, move the circuit breaker switch to the fully clockwise position. The red target will be visible. The generator circuit breaker will close. The genset will be paralleled with the utility.
- Start
The generator output is gradually increased to the setpoint for base load operation. The setpoint for base load operation was previously set by using the touchscreen display. The generator output will remain at the setpoint for base load operation until the unit receives a shutdown signal.

- Open the generator circuit breaker before the generator reaches 0 kW.
- Move the engine control switch to the "COOLDOWN STOP" position.
The engine will run without a load for the cooldown period. The engine will automatically shut down.

- Move the engine control switch (ECS) to the MANUAL START position.
Note: The genset will perform these operations:
- Start
- Go to rated speed
- Go to rated voltage
Note: The manual loading potentiometer should be adjusted in order to provide a small load on the engine when the generator circuit breaker is closed.
- Start
- Monitor the synchronizing lights. When both lights are OFF, move the circuit breaker switch to the fully clockwise position.
The red target will be visible. The generator circuit breaker will close. The genset will be paralleled with the utility.
- Gradually increase the potentiometer for the manual loading control (MLC) to the desired generator output.
The generator output will remain at this load level.
