DKG-329 User Manual V-12 (09.10.2012)
- 10 -
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+Load_dump+Warning 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+Load_dump+Warning 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+Load_dump+Warning 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.
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.
MAINS CB FAIL TO CLOSE (warning): Set if the mains contactor feed back input is not active at the end
of mains contactor timeout when mains contactor is activated. Enabled if one of digital inputs assigned as
mains contactor feed back input.
MAINS CB FAIL TO OPEN (load_dump): Set if the mains contactor feed back input is still active at the
end of mains contactor timeout when mains contactor is deactivated. Enabled if one of digital inputs
assigned as mains contactor feed back input.
GENSET CB FAIL TO CLOSE (warning): Set if the genset contactor feed back input is not active at the
end of genset contactor timeout when genset contactor is activated. Enabled if one of digital inputs
assigned as genset contactor feed back input.
GENSET CB FAIL TO OPEN (warning): Set if the genset contactor feed back input is still active at the
end of genset contactor timeout when genset contactor is deactivated. Enabled if one of digital inputs
assigned as genset contactor feed back input. The mains contactor cannot operate when this warning is
up.
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.
