2 Yes The control unit automatically clears the alarm if the fault condition is no
longer detected.
[No] The control unit does not automatically reset the alarm when the fault condi‐
tion is no longer detected.
The alarm must be acknowledged and reset by manually pressing the appro‐
priate buttons or by activating the LogicsManager output "External acknowl‐
edgement" (via a discrete input or via an interface).
If an engine stop has been detected without a stop command being
issued, an alarm will be initiated.

cates "Eng. stop malfunct." and the logical command
variable "05.06" will be enabled.
We recommend to assign this monitoring function to a
discrete output to be able to shutdown the engine with
an external device to provide a shutdown redundancy.
