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
:
CAN2empt
Detect.
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
