Description
protection too.
Gen V unbal
A+H
Generator voltage unbalance alarm is based on Gener
protect: Gen V unbal and Gen V unb del setpoints. The
voltage unbalance is calculated as a maximum difference
between phase voltages.
Gen I unbal
A+H
Generator current asymmetry (unbalance) alarm is based
on Gener protect: Gen I unbal and Gen I unb del
setpoints. The current unbalance is calculated as a
maximum difference between phase currents.
BusL I unbal
A+H
Left bus current asymmetry (unbalance) alarm is based on
Gener protect: BusL I unbal and BusL I unb del setpoints.
The current unbalance is calculated as a maximum
difference between phase currents.
Mains V unbal
A+H
Mains voltage unbalance alarm is based on Mains
protect: Mains V unbal and MainsV unb del setpoints. The
voltage unbalance is calculated as a maximum difference
between phase voltages.
Mains I unbal
A+H
Mains current asymmetry (unbalance) alarm is based on
Mains protect: Mains I unbal and Mains Iunb del
setpoints. The current unbalance is calculated as a
maximum difference between phase currents.
Bus V unbal
A+H
Bus voltage unbalance alarm is based on Gener protect
(Bus protect): Bus V unbal and Bus V unb del setpoints.
The voltage unbalance is calculated as a maximum
difference between phase voltages.
BusL V unbal
Left bus voltage unbalance alarm is based on BusL
protect: BusL V unbal and BusL V unb del setpoints. The
voltage unbalance is calculated as a maximum difference
between phase voltages.
BusR V unbal
Right bus voltage unbalance alarm is based on BusR
protect: BusR V unbal and BusR V unb del setpoints. The
voltage unbalance is calculated as a maximum difference
between phase voltages.
Dongle incomp
A+H
Incompatible (usually missing) dongle indication.
IGS-NT-LSM+PMS dongle (green one) is required if load
sharing and power management functions are used in
MINT, COX or COMBI application.
Check a Reference Guide for information whether a dongle
is required for requested functionality or not.
Incom. periph.
A+H
If the incompatible modules are used and the
communication to this module cannot be established, this
alarm and history event are recorded.
Emergency stop
A+H
Emergency stop activity indication. Check binary input with
Emergency stop function.
CAN2 bus empty
A+H
This alarm is active if controller doesn’t “see” any other
controllers on the CAN2 bus. Alarm activation can be
enabled/disabled using setpoint Comm settings:
CAN2emptDetect. This setpoint should be set to
DISABLED for single genset applications.
Check Reg16/Reg32 strings to see which controllers are in
the same group
18
.
ChrgAlternFail
A+H
Charger fail detection. This alarm means that voltage on
the D+ terminal is lower than 80% of controller power
supply voltage and it means that battery is no longer
charged. Check function of engine alternator or
