Fuel solenoid is switched on with advance of 1s fixed before starter motor is switched on.
Note:
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.
9.4 AUT mode
The controller does not respond to
,
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) -
Regulator
setpoints group.
9.5 Engine without pickup operation
The RPM pickup input is ignored when
Engine params
: Gear teeth = 0. The engine running state is then
detected based on
Engine params
: Starting POil or
Engine params
: D+ function = ENABLED.
Starting Poil
signal can be analog or binary. Even the binary signal is to be connected to AIN1 input. In LiteEdit,

9.6 Engine timer
9.6.1 MAN mode
Set the
Engine params
:
Running Timer
. Start engine in MAN mode by START button. Engine stops itself after

is over. The STOP button cancels timer (forces cooling), the second STOP cancels cooling
(forces engine stop). Engine stays running when

= 0.
