4. ALARMS AND WARNINGS
Alarms indicate an abnormal situation in the generating set are divided into 3 priority levels:
1-
ALARMS:
These are the most important fault conditions and cause:
-
The
ALARM
led to be on steadily,
-
The genset contactor to be released immediately,
-
The engine to be stopped immediately,
-
The
Horn
,
Alarm
,
Alarm+Load_dump
and
Alarm+LoWarning
digital
outputs to operate, (if selected via programming menu)
2-
LOAD_DUMPS:
These fault conditions cause:
-
The ALARM led to flash,
-
The genset contactor to be released immediately,
-
The engine to be stopped after Cooldown period,
-
The
Horn
,
Alarm+Load_dump
and
Alarm+LoWarning
digital outputs to
operate, (if selected via programming menu)
3-
WARNINGS:
These conditions cause:
-
The WARNING led to be on steadily,
-
The
Horn
and
Alarm+LoWarning
digital outputs to operate, (if selected
via programming menu)
If the ALARM MUTE button is pressed, the Horn output will be deactivated; however the
existing alarms will persist and disable the operation of the genset.
Alarms operate in a first occurring basis:
-If an alarm is present, following alarms, load_dumps and warnings will not be accepted,
-If a load_dump is present, following load_dumps and warnings will not be accepted,
-If a warning is present, following warnings will not be accepted.
Alarms may be of LATCHING type following programming. For latching alarms, even if the alarm
condition is removed, the alarms will stay on and disable the operation of the genset. The existing
alarms
may be canceled
by pressing one of the operating mode buttons (
LOAD TEST / TEST / OFF / AUTO
).
Most of the alarms have programmable trip levels. See the programming chapter for adjustable
alarm limits.
LOW OIL PRESSURE:
Set if a signal is detected at the Low Oil Pressure Switch input or the oil
pressure value measured from the sender is below the programmed limit. Warning and alarm limits are
separately programmable for the oil pressure sender input. This fault will be monitored with
Holdoff
Timer
delay after the engine is running. Also if the oil pressure switch is open at the beginning of a start
attempt, then the engine will not be started and “
Oil Pressure Exists!
” information is displayed. When
the oil pressure switch closes, normal operation will be resumed.
HIGH TEMPERATURE:
Set if a signal is detected at the High Temperature Switch input or the coolant
temperature value measured from the sender is above the programmed limit. Warning and alarm limits
are separately programmable for the temperature sender input.
LOW TEMPERATURE (warning) :
Set if the coolant temperature value measured from the sender is
blow the
Engine Heating Temperature
limit.
LOW FUEL:
Set if a signal is detected at the low fuel level input or the the fuel level measured from the
sender is below the programmed limit. Warning and alarm limits are separately programmable for the
fuel level sender input.
RECTIFIER FAIL:
Set if a signal is detected at the rectifier fail input. This input is only monitored when
mains voltages are present.
EMERGENCY STOP:
Set if a signal is detected at the emergency stop input.
SPARE-1 / SPARE-2:
Set if a signal is detected from the related spare fault input.
