Faults Engine management Switch off prompt for the operator. Attention: Failure to do so will lead to loss of guaran- tee! The engine has reached switch-off condition. Engine forced to run at low idle speed to cool the engine, with automatic shutdown if nec- essary. The switch-off process has been accom- plished. There may be a start lock after engine stop. The start lock is deactivated by turning off the system with the ignition key for approx. 30s. The power reduction can be bypassed, the automatic switch-off delayed or a start lock bypassed with the override key on the instru- ment panel to avoid critical situations.
This brief deactivation of the engine protection functions is logged in the control unit. Please contact your DEUTZ-partner in case of malfunctions and sare parts inquiries. Our spe- cially trained personnel will ensure fast, profes- sional repairs using original DEUTZ spare parts in case of damage. 66 © 2009 Depending on the seriousness of a recognised fault, the engine can continue to operate with limitations, during which the error lamp lights up continuously or indicates a serious system error by flashing. In this case, the engine should be switched off as soon as safely possible. z Function test Ignition on, error lamp lights up for approx. 2 seconds and then goes out.
Check the error lamp if there is no reaction after switching on the ignition. z The lamp does not light After the lamp test an extinguished lamp indi- cates an error-free and trouble-free operat- ing state within the scope of the control possibility. The error lamp is located in the vehicle drive stand. The error lamp can release the following signals: z Continuous light Error in system. Operation continued with restrictions. The engine must be checked by a DEUTZ partner. If a lamp lights steadily a monitored measur- ing variable (e.g. coolant temperature, lubri- cating oil pressure) has left the permissible value range.
Depending on the fault, the engine power may be reduced by the electronic engine control to protect the engine. z Flashing Serious error in system. Error lamp Engine protection function of the electronic en- gine control The error lamp goes out when all the errors have been eliminated. For some errors, it is necessary to switch off the ignition, wait 30 s and only then switch back on the ignition. The appropriate monitoring functions are switched off when a sensor fails. Only the sensor failure is documented in the error memory.
Depending on the design of the monitoring functions, the electronic engine control can protect the engine in certain problematical situations by monitoring im- portant limit values during operation and checking the correct function of the system components.
