Notes
All functions which are described here, may be assigned by the LogicsMan‐
ager to any relay that is available via the LogicsManager and not assigned to
another function.
2 0 to 999 s Prior to each start, the diesel engine is preheated for this time (if a "0" has
been configured here the engine will be started without preglow).
[5 s]
Notes
The display indicates "Preglow".
2 This parameter dictates if and under what conditions a diesel engine is pre‐
heated.
Off The diesel engine is never preheated before a start attempt.
[Always] Before a start attempt the "Preheating" relay is always energized for the pre‐
glow time (parameter

2 1 to 999 s With gas engines often a purging operation is desired before starting.
[5 s] With the engaging of the starter the ignition delay is started. The display indi‐
cates "Turning".
If the "Minimum speed for ignition" is reached after the expiration of this time,
the ignition is energized.
2 0 to 999 s By energizing the ignition relay the gas valve delay is started ("Ignition" is dis‐
played).
[5 s]
After the time set here has expired, and as long as the speed is higher than
the minimum speed for ignition, the gas valve is enabled for the time config‐
ured in parameter
Once the ignition speed has been reached, the gas valve remains opened. If
the speed falls below ignition speed, the gas valve will be closed and the
"Ignition" relay is de-energized 5 seconds later.
2 10 to 1,800 rpm After expiration of the ignition delay the number of revolutions set here must
be reached, so the "Ignition" relay will be energized.
