Threshold level for D+ input is 80% supply voltage; activation delay is 1s (to override short firings
during cranking
– for example in cold conditions).
Speed request:
Engine speed is constant or set manually using
Engine params
setpoints and Binary inputs.
6.4 AUT mode
The controller does not respond to START, STOP buttons. Engine start/stop request is given by
binary input REM START/STOP.
Engine speed request is sourced from PI loop (see below function 3) in AUT mode.
PI loop and Hysteresis comparator functions can be used both for Engine Load Limitation or any other
control function.
Speed request:
Engine speed is adjusted automatically by internal PID loops (when active) -
