LOW SPEED / HIGH SPEED:
Set if the generator frequency is outside programmed limits. These faults
will be monitored with
Holdoff Timer
delay after the engine is running. Low and high limits for warning
and alarm are separately programmable. Another high frequency shutdown limit which is 12% above the
high limit is always monitored and stops the engine immediately.
START FAIL (alarm):
Set if the engine is not running after programmed number of start attempts.
STOP FAIL (warning):
Set if the engine has not stopped before the expiration of the
Stop Timer
.
OVERLOAD (load_dump):
Set if at least one of the genset phase currents goes over the
Overcurrent
Limit
for
Overload Timer
. If currents goes below the limit before expiration of the timer then no alarm will
be set.
EXCESS POWER (load_dump):
Set if the genset power (KW) supplied to the load goes over the
Excess Power
limit for
Overload Timer
. If the power goes below the limit before expiration of the timer
then no alarm will be set.
GENSET LOW VOLTAGE:
Set if any of the generator phase voltages goes outside programmed limits
for
Overload Timer
. This fault will be monitored with
holdoff timer
delay after the engine is running.
GENSET HIGH VOLTAGE:
Set if any of the generator phase voltages goes outside programmed limits
for
Overload Timer
. This fault will be monitored with
holdoff timer
delay after the engine is running.
LOW BATTERY VOLTAGE (warning):
Set if the battery voltage goes below the programmed limit.
During engine cranking this fault is not monitored.
HIGH BATTERY VOLTAGE:
Set if the battery voltage goes above programmed limits. Both warning and
alarm levels for high battery voltage are programmable.
CHARGE:
Set if a charge alternator failure (or broken belt) occurs. This fault condition may result to a
warning
or
alarm
following programming.
MAINS PHASE ORDER FAIL (warning):
Set if the mains phase order checking is enabled, mains
phases are present and mains phase order is reversed. This fault prevents the Mains Contactor to close.
