Preliminary work for measurement 10
Release and disconnect 12-volt connection for power electronics.
12-volt connection for power electronics
Perform measurement 10.
Measurement 10
Measure resistance at pin 55 and pin 80 of the 12-volt connection for power electronics.
Refer to the wiring diagram for the pin assignment of the connectors
Setpoint value < 0.5 Ohm
Evaluate measured result
If the measured value is within the tolerance range, repeat measurements for pilot line fault finding. Contact Technical Support.
If the measured value is outside of the tolerance range, visually inspect connectors and repair them if necessary. After carrying out repairs, repeat measurement 10.
