2 Information about the engine electronics Electrics/Electronics Engine description DEUTZ control units are equipped with self-diagnos- tics. Active and passive error entries are saved in the error memory. Active errors are displayed on error lamps/diagnostics lamps ( 66 ). The DEUTZ AG installation regulations should be adhered to. In particular, the plug contact must be crimped with the appropriate standard tools. If it is necessary to do so, plugged-in contacts may only be removed from the plug housing with the proper tools. © 2009 23 A diagnosis can be made with:
z Error lamp (flash code) z CAN bus z DEUTZ electronics display z Diagnostic socket (SERIDA) Equipment-side wiring Diagnostics It should be ensured that the battery is sufficiently charged. If the supply voltage is interrupted while the engine is running, this can lead to damage to the electrics/electronics. If the supply voltage fails, the engine shuts down. It is strictly prohibited: a) to make changes or connections to the wiring of the electrical control devices and the data transmission cable (CAN lines). b) to switch control units. Otherwise guarantee rights will be lost! Diagnostic and maintenance work may only be carried out by authorised personnel using equipment approved by DEUTZ.
The control units are calibrated to the respective en- gine and identified by the engine number. Every en- gine may only be operated with the appropriate control unit. Setpoint transmitters (pedal value transmitters) nec- essary for vehicle operation must be connected to the vehicle side cable harness and calibrated with the DEUTZ diagnostic program SERDIA (SERvice DIAgnosis). Wiring and cable assignment of the ve- hicle side cable harness must be taken from the con- nection diagram of the DEUTZ installation consulting. Voltages above 32 Volt will destroy the control unit. Installation instructions Supply voltage 12 Volt 24 Volt This engine is equipped with an electric control unit.
The equipping of the respective system depends on the desired scope of function and the planned type of engine application. The resultant wiring with pin assignment can be seen in the appropriate wiring diagram. The installation regulations of the DEUTZ AG must also be taken into account. The connections of the control units are only dust and water proof when the mating plugs are plugged (protection class IP69K)! The control units must be protected against spray water and moisture until plugging in the mating plugs! Reverse polarity can lead to failure of the control unit.
To avoid damaging the control units, all the connections on the control unit must be dis- connected before electric welding work. Interventions in the electrical system con- trary to the DEUTZ regulations or by un- qualified personnel can permamently damage the engine electronics and have serious consequences which are not cov- ered by the manufacturer's guarantee.
