DKG-509 User Manual V-29 (23.08.2013)
- 11 -
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.
