if CAN communication is interrupted, the fol-
lowing emergency operation option is provided:
A CAN fault or throttle opening fault in an all-
speed engine (both signal and idling switch):
• The throttle opening value is 0% and the en-
gine is running at normal idling speed.
• The throttle opening value is 0% and the en-
gine is running at raised idling speed (750
rpm) if this function is activated.
Throttle opening fault, but the idling switch is
working:
• The throttle opening value can be increased
slowly between 0 and 50% by using the idling
switch.
CAN fault:
• The engine is switched off if the shutdown
function is activated.

ment system.
Low idling up to 2,300 rpm The engine operating speed range, depending on power class.
2,300-2,600 rpm Unsuitable operating speed, but a slightly higher engine speed
than the normal maximum operating speed may occur when
load is low or negative.
