3 Electronic engine control Operation monitoring Operation z Colour scale Display of operating state by coloured areas: green = normal operating state red = critical operatng state Take suitable action. z Measured value scale Actual value can be read off directly. The nominal value should be taken from the Technical Data ( 72 ). © 2009 29 Display instrument Possible displays: 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. Additional control lamps, e.g. for lubricating oil pressure or lubricating oil temperature, are switched on if necessary.
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. The engine protection functions are released in co-operation with the equipment manufacturer and the DEUTZ installation consulting and may be designed individually. It is therefore absolute- ly essential to observe the operating instructions of the equipment manufacturer. The system monitors the condition of the engine and itself. 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. z Continuous light Error in the 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 pro- tect the engine. z Flashing Serious error in the system.
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- The statuses are displayed by the error lamp.
