VOLTAGE UNBALANCE
Set if any of the generator phase voltages differs from the average by more
than
Voltage Unbalance Limit
for
Voltage Fail Timer
. This fault will be
monitored with
Fault Holdoff Timer
delay after the engine is running.
CURRENT UNBALANCE
Set if any of the generator phase currents differs from the average by more
than
Voltage Unbalance Limit
for
Voltage Fail Timer
. This fault will be
monitored with
Fault Holdoff Timer
delay after the engine is running. The
action taken at fault condition is programmable.
OVERCURRENT
Set if at least one of the genset phase currents goes over the
Overcurrent
Limit
for the period allowed by the IDMT curve setting. The allowed timer is
dependent of the overcurrent level. If currents go below the limit before
expiration of the timer then no alarm will be set. Please check chapter
Overcurrent Protection (IDMT) for more details. The action taken at fault
condition is programmable.
OVERLOAD
Set if the genset power (kW) supplied to the load goes over the
Overload
Load Dump
limit for
Overload Timer
. If the power goes below the limit
before expiration of the timer then no alarm will be set.
REVERSE POWER
Set if the genset power (kW) is negative and goes over the
Reverse Power
limit for
Reverse Power Timer
. If the power goes below the limit before
expiration of the timer then no alarm will be set.
GENSET PHASE ORDER
FAIL
Set if the fault is enabled and the genset phase order is reverse.
MAINS CB FAIL TO
OPEN
Set if the feedback input is defined and the related contactor block
feedback signal is not detected after the expiration of Contactor
Open/Close Fail Timer.
GENSET CB FAIL TO
CLOSE
Set if the feedback input is defined and the related contactor block
feedback signal is not detected after the expiration of Contactor
Open/Close Fail Timer.
PICKUP SIGNAL LOST
Set if the rpm measured from the magnetic pickup input falls below the
Crank Cut RPM
level during
Loss of Speed Signal Timer
. The action of
signal loss is programmable.
SERVICE REQUEST
Set if at least one of the service counters has expired. In order to reset the
service counters please hold pressed both
and
buttons during 5
seconds. The screen will display “Completed!”
UNIT LOCKED
Set if the controller is remotely locked.
UNKNOWN TOPOLOGY
Set if the automatic topology determination is active, and the topology
cannot be determined during “Holdoff timer” after the engine runs.
Digital input and analog sender alarms are fully programmable
for the alarm name, sampling and action.
Only internal alarms are explained in this section.
