Operational
Output closes with binary output Prestart and opens with binary output Cooling pump (see setpoint Engine
params: AfterCoolTime).
Timer Active
Binary output Timer Active is closed and opened according to Timer setpoints setting. Engine starts and
stops when this output is connected (configured) to Binary input Rem Start/Stop. Timer is active in all
controller modes include OFF mode.
Alarm BlinkAct
It follows the panel Red LED. Starts blink after any (Wrn, Sd) Alarm is activated, light after Fault reset,
disappear after Fault reset when no alarm is active.
Common SdO
Indicates any active protection configured as Shut down Override.
Derating Alarm
Power derating indication, information received from J1587 communication bus.
RdyForRemStart
Indicates Ready state for Remote engine start.
ECU PowerRelay
The output closes at the beginning of prestart and opens if the engine shall be stopped.
This output can be used to indicate when the ECU should be powered up i.e. only while the engine is
running.
This output also influences evaluation of communication failure with ECU and related FLS alarms from
analog inputs read from the ECU. If the output is configured (which means configured on physical binary
output or VBOUT output), the issuing of communication error is blocked during Prestart and Stopping
procedure as shown in the picture.
Hint:
The input must be configured on physical binary output or VBOUT output. It is not enough to configure it as a
PLC input for example.
