Overcurrent
The output closes if the generator IDMT Overcurrent or Shortcurrent alarm activates. The output opens, if
none of these alarms is active and FAULT RESET has been pressed.
ECU comm error
Output closes if there is an error in the communication with ECU. It doesn’t matter how the ECU is
connected – J1939 link or RS232 line.
PeriphCommErr
Output closes if there is an error in the communication with any peripheral unit (e.g. IS-AIN8, IGS-PTM, ...).
CtrlHBeat FD
BI "CtrlHBeat sens" should be assigned to the output "CtrlHeartBeat" from the other controller. If input signal
does not correspond to right form (log 1 / log 0 - 500 ms / 500 ms; +/- 100 ms), BO: "CtrlHBeat FD" (Fail
Detect) is activated. This BO can be used for primary controller blocking (switching to Emerg. manual,
disconnecting BO, ...) and mainly for disconnecting of BI "Emerg. manual" of this controller. What means that
the backup controller assumes engine control.
CAN2 bus empty
The output closes if the controller doesn’t “see” any other controllers on the CAN2 bus. The output activation
can be blocked by setpoint Basic settings:CAN2emptDetect
(So it should be DISABLED for single
applications.)
Binary outputs – Configurable prog. states
ECU
Indication of J1939 communication fail (configurable between Nop protection, Warning or Shutdown).
SHBinCfGErr
Shared Binary module configuration error – i.e. more than one source was configured (is on the CAN2 bus).
SHAinCfgErr
Shared Analog module configuration error – i.e. more than one source was configured (is on the CAN2 bus).
PLC State 1 .. 4
PLC state indication.
ECUDiagBlocked
Output is active when Basic setting: ECU diag = DISABLED..
WrongConfig
Wrong configuration indication.
Batt volt
Indication of battery voltage protection based on Analog protection: Batt >V, Batt <V, Batt V del.
EarthFaultCurr
Indication of Earth fault current protection based on Gener protect: EarthFaultCurr and EthFltCurr del.
Dongle incomp
Incompatible dongle indication.
