Starting
z Engine is controlled electronically, e.g. with
electronic engine control EMR3.
Engine is programmed and supplied with the
necessary function configurations.
z Separate engine from driven devices by dis-
connecting if possible.
Before starting make sure that there is
nobody in the engine / work machine
danger area! After repairs: Check that
all protective equipment is mounted
and all tools have been removed from
the engine! When starting with heating
plug/spark plug/heating flange do not
use any additional starting devices
(e.g. injection with start pilot). Danger
of accidents!
If the engine does not start and the
fault lamp flashes, the EMR3 system
has activated the start lock to protect
the engine.
The start lock is released by switching
off the system with the ignition key for
about 30 s.
Separate the engine if possible by dis-
engaging driven units.
Start the engine for a maximum of 20
seconds uninterrupted! If the engine
does not start up, wait for one minute
and then repeat the starting process.
If the engine does not start up after two
starting processes, determine the cau-
se as per fault table (see 7.1).
Do not run up the engine immediately
to high idling speed / full load operation
from cold.
z Do not run up the engine immediately to
high idling speed / full load operation from
cold.
z If the starter is connected by a relay on the
EMR3,
– the maximum starting time is limited by
the EMR3.
– the pause between two start attempts is
specified by the EMR3.
– If the touch start function is programmed,
a short start command with the ignition
key in position 2 suffices, or a start button
if available.
– The start is then continued automatically
by the EMR3.
– For special applications, the EMR3 can
be programmed by a data record so that
the control unit also carries out automatic
further start attempts if the engine does
not start.
