Engine Shut-down is activated by Binary input “Oil press”.
ECU PwrRelay
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 VPIO 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 VPIO output. It is not enough to configure it as a
PLC input for example.
