4.6.9.1 Electronic engine control's (EEC)
engine protection function
The EEC protects the diesel engine against
damage by monitoring compliance with im-
portant limit values during operation.
Depending on the severity of an error that has
been detected, the diesel engine can continue
to run with some limitations (possibly at re-
duced output, in which case the indicator
(62/68) will light up and remain lit) or the die-
sel engine is turned off, in which case the in-
dicator (62/68) will flash. As soon as the error
is no longer present, the indicator (62/68)
goes out.
If the EEC has switched over to emergency
speed, the diesel engine must be turned off
with the ignition key (62/60) for at least 30
seconds to allow the indicator (62/68) to go
out.
Errors that have been corrected or are no
longer current still remain stored in the error
memory of the control unit.They can be read
or deleted with the DEUTZ diagnostics soft-
ware program SERDIA.
To avoid damage to the control de-
vice, the three plug connections
(63/1) on the engine controller as
well as the positive cable of the bat-
tery must be disconnected before
performing welding jobs on the ma-
chine! The positive cable of the bat-
tery must be connected to the adja-
cent grounding bolts. The battery
isolator switch should be switched
off.
In the event of malfunctions affecting the sys-
tem, please contact customer service.
