Blackout Start (AUX, EME, CMB-EME, CMB-HRB)
External “edge sensitive” request for engine start. Input is inactive in LOC (Local) mode. Adjustable number
of attempts (see setpoints Engine params: Crank Attempts, MaxCrank Time and Cranking Pause).

Hint:
The setpoint Crank Attempts is not followed if Sd Override is active, crank attempts number is then
unlimited in case of Blackout Start.
Back Up Speed (PRP only)
If input is active and Logical Analog input Requested RPM is not valid (out of range, sensor fail),
Loadsharing: ThrottlePos is set to Load sharing: Back Up Speed value. Loadsharing: ThrottlePos = 0,0%
when analog request is out of range and Binary input Back Up Speed is not active.
Fire Speed (PRP only)
If active, clutch is disconnected and Loadsharing: ThrottlePos is set to Engine params: FireAlarmSpeed,
the ThrottlePos value change is influenced by ramp specified by Loadsharing: RQSP Ramp.
Rem Clutch (PRP only)
If active closes binary output Clutch Connect – see Clutch Connect (PRP only).
StartBlocking1 .. StartBlocking5
OR logical function of all StartBlocking Logical Binary inputs forces controller NotReady state ( i.e. disables
engine start). It is active in LOC (Local) mode as well.
