Low Power
2
The event appears in the Alarmlist and is recorded into the history log. It
does not require confirmation, diappears by itself.
It causes reduction of the required gen-set load to the Min Power PtM
during parallel-to-mains operation or local baseload operation.
If all previously active Low power alarms disappeared the gen-set is
automatically ramped back to the original required load, which is given
according to the currently active load control mode (Load ctrl PtM) in PtM
operation.
Activates the output Common LoP.
This alarm type is not overriden by the input Sd Override.
Note:
Available in IS-NT only.
BrkOpen&CoolDn 2
The event appears in the Alarmlist and is recorded into the history log.
It causes immediate opening of the GCB (without unloading) and then the
standard stop sequence with cooling follows.
The gen-set can't be started again while there is a BOC alarm in the
Alarmlist.
Activates the output Common BOC as well as the standard alarm outputs.
Mains Protect
2
The protection is only recorded into the history log.
In applications which control the MCB this protection causes opening of the
MCB. The gen-set can continue operation in island mode if required. The
MCB can be closed back as soon as there isn't any mains protection active
(including the built-in mains protections).
In applications which do not control the MCB this protection causes
opening of the GCB. The controller waits then for the MCB to open. After
that the gen-set can continue operation in island mode if required. As soon
as there isn't any mains protection active (including the built-in mains
protections) the GCB is opened again and the controller waits for the MCB
to close. After that the gen-set can continue operation in parallel-to-mains
mode if required.
Activates the output Common MP.
This alarm type is not overriden by the input Sd Override.
Sd Override
2
The alarm appears in the Alarmlist and is recorded into the history log.
It causes immediate stop of the gen-set without unloading and cooling
phase.
The gen-set can't be started again while there is a Sd override alarm in the
Alarmlist.
Activates the standard alarm outputs.
This alarm type is not overriden by the input Sd Override.
*) Yellow color of Gen-set indication LED is available only in IS-NT. In IG-NT, „Y“ indication of LED means
that both red and green LEDs are on.
Hint:
The Standard alarm outputs are Alarm and Horn.
Sensor fail detection (FLS)
If the measured resistance, voltage or current on an analog input gets out of valid range, the sensor fail will
be detected and a sensor fail message will appear in the alarmlist. The valid range is defined by the most-left
(R
L
) and most-right (R
H
) points of the sensor characteristic ±12.5% from R
H
-R
L
.
