Digital Controller List of Alarms
Alarm Definition
ECU
Indication of error in communication with ECU.
Check if the ECU is:
• Correctly connected to the CAN1 port of the controller (refer to
Comap Electronic Engines Support manual for information about
ECU connection)
• Powered up
• Terminating resistors are properly connected
• CAN bus Low and High wires are not swapped
SHAinCfgErr
Shared Analog module configuration error – i.e. more than one source
module (SHAOUT) were configured (on the CAN2 bus). Make sure that
only one SHAOUT x module is configured in controllers.
ECUDiagBlocked
Alarm is active when Comms settings: ECU diag = DISABLED. This set-
ting means that ECU alarms are not displayed and considered by control-
ler and this alarm is the setting notification.
Wrong config
Wrong controller configuration indication.
Indicates that controller hardware doesn't support PLC used in configura-
tion. To check it send the IDch and Dngl strings3 from controller Info
screen 2 and archive to your technical support.
RTCbatteryFlat
Appears in Alarmlist when battery is close to being completely flat.
If power supply cut comes when the RTC battery is flat, the statistic val-
ues, history and setpoints settings are lost. Send a controller to your dis-
tributor for battery exchange if the RTCbatteryFlat message is displayed.
Al/Hist. msg 1-165
Al/Hist. msg 1-16 activity indication (Al/Hist. msg means Alarm/History
message). Al/Hist. msg can be used as a customized message for addi-
tional protection configured to any controller internal value. See GenCon-
fig manual - Protections.
Batt volt
Indication of battery voltage protection activity. This protection is based on
Analog protect: Batt >V, Batt <V, and Batt volt del setpoints. Check if
engine alternator or independent battery charger works properly.
EarthFaultCurr
Indication of Earth fault current protection activity. This protection is based
on Gener protect: EarthFaultCurr and EthFltCurr del setpoints. Setpoint
EarthFltCurrCT from Basic settings group of setpoints is related to this
protection too.
Gen V unbal
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
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.
BusL I
unbal 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
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
Mains current asymmetry (unbalance) alarm is based on Mains protect:
Mains I unbal and Mains Iunb del setpoints. The current unbalance is cal-
culated as a maximum difference between phase currents.
Bus V unbal
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.
