Table 2. Generator Set Control Controls and Indicators Continued.
Red indicator flashes when engine speed rises above programmed setpoint for engine
overspeed. Engine shuts down and does not start until fault is corrected.
Red indicator flashes when engine does not start within programmed setpoint for total
cycle crank time. Engine not allowed to start until fault is corrected.
Indicator lights (key 6 thru 8) perform dual functions depending on
the position of the UNIT/PARALLEL switch.
When UNIT/PARALLEL switch is set to UNIT (FUNCTION I),
the indicators display the following.
Yellow light flashes when coolant level drops below probe of coolant loss sensor.
Engine shuts down and does not start until fault is corrected.
Yellow indicator lights when BATTLE SHORT switch is set to ON. Indicates TQG
is operating in battle short condition.
IN 50 Hz MODE
Yellow indicator lights when TQG is in 50 Hz mode.
When UNIT/PARALLEL switch is set to PARALLEL
(FUNCTION II), the indicators display the following:.
~ V (left side of light)
Yellow indicator flashes in paralleling mode until TQG and paralleling bus voltages
are within acceptable limits. Yellow indicator lights when voltages match.
HZ (left side of light)
Yellow indicator flashes in paralleling mode until TQG and paralleling bus
frequencies are within acceptable limits. Yellow indicator lights when frequencies
(left side of
Yellow indicator flashes in paralleling mode until TQG and paralleling bus phases
are within acceptable limits. Yellow indicator lights when phases match.
Red indicator flashes when GSC detects a fault that is a shutdown fault. If engine is
running, it is shut down. The engine will not start. A diagnostic code is displayed
on upper GSC display (11). Diagnostic codes are described in Chapter 3,
Yellow light flashes when GSC detects an alarm fault. Alarm fault does not cause
engine status to change and engine will continue to run. If engine was not started,
it may be started. A diagnostic code is displayed on upper GSC display (11) when
ALARM CODES (17) key at bottom of GSC is pressed. Diagnostic codes are
