1 A wire breakage has been detected on the respective output. Check wiring!

Troubleshooting aids:

remove the connector and measure the resistance on respective terminals of the plug connector to check the individual valve coils. On-off valves typically have a 15 to 30 ohm coil resistance. If several outputs are reporting broken wires, an interrupted common return line is probably the cause. If the resistance measurement cannot detect a problem, the cross-section of the common return line may be too small.

3 A short circuit has been detected on the respective output. Check wiring. Troubleshooting aids: Remove the controller and measure the resistance and voltage on the respective terminals to determine the type of short circuit. Short circuits to earth or to +24 volts are possible. The voltage must not exceed 3V on the output terminals.

3 A wire breakage has been detected on the respective output. Check wiring!

Troubleshooting aids:

remove the connector and measure the resistance on respective terminals to check the individual valve coils. Proportional valves (9V coils) typically have a coil resistance of 2,0 to 3,5 Ohm. If several outputs are reporting broken wires, an interrupted common return line is probably the cause. If the resistance measurement cannot detect a problem, the cross-section of the common return line may be too small.

Troubleshooting aids:

the 5V reference supplies the angle transmitters and the pressure sensors. With the controller plugged in measure the voltage on terminal J10.4, it should be 5V. If the voltage is different, disconnect the angle transmitters and sensors briefl y in turn to locate the faulty connection. The screening of the connected sensors should also be checked.

40 Axle track1 angle transmitter 02 Wire breakage

05 Parameter prog 1 The loop voltage is in the wire breakage area. Check wiring on this angle transmitter.

Troubleshooting aid for potentiometer angle transmitters:

the angle transmitter may not be energised or has moved too far. A wire breakage on “5V-Ext.” or “5V-Ref.” is also possible. Use the PC service software to record the voltage on the corresponding analog input.

Voltage > 4,8 V: - Loop short circuit against +5Vref, +5Vext or 24 V. Angle transmitter moved too far? - Wire breakage on signal earth of angle transmitter on track 1? Voltage < 0,2 V: - Loop short circuit against signal earth or against truck earth - Wire breakage between loop and angle transmitter. - Wire breakage between +5Vref and angle transmitter - Angle transmitter moved too far?

For a more precise localisation, measure the following resistances with the controller unplugged.

Between the terminal +5Vref and signal earth. As at least 2 tracks are connected respectively, approx. 1000 Ohm (750 - 1250 Ohm) should be recorded. If there is a deviation from this, there is a wire breakage/ short circuit of the output “5V Ref.” or of “0V signal”. 0 Parameter P_64 incorrectly programmed.

17 Sumtrack 1/2 2/3 Sum of loop voltages implausible. The second angle transmitter track may have twisted power supply connections.

Error priority for setpoint device = 2, for axles = 3

Troubleshooting aids for potentiometer angle transmitters:

for trucks in use: Is the angle transmitter is damaged? Check the course of the angle transmitter voltages. Check the connection of the angle transmitter screening.

Using the truck for the fi rst time: Display the angle transmitter voltages with the PCS. When the main articulated joint is steered from the left to the right stop, the track1 voltage of the corresponding angle transmitter should rise. If the voltage is correct on track1 (increasing voltage for left turn), track2 of the angle transmitter is incorrectly energised. If the voltage is incorrect (decreasing voltage for left turn) track1 of the angle transmitter is incorrectly energised. On the corresponding track the wires to/from the supply pins must be replaced for the current track. 18 Difference track 1/2 2/3 The angles obtained between track 1/2 differ by more than the values entered in parameter P_65. Error priority for setpoint device = 2, for axles = 3

Troubleshooting aids:

If the angle transmitter or the controller has been replaced, the angle transmitters must be adjusted again.

For trucks in use:

Check the connection of the corresponding angle transmitter screening.

Using the truck for the fi rst time:

The angle transmitter must still be adjusted

1 The “5V external” power supply is out of range! Check the wiring by the connected angle transmitters and pressure sensors. There may be a short circuit.

Troubleshooting aids for potentiometer angle transmitters:

the 5V reference supplies the angle transmitters and the pressure sensors. With the controller plugged in measure the voltage on terminal J2.11, it should be 5V. If the voltage is different, disconnect the angle transmitters and sensors briefl y in turn to locate the faulty connection. The screening of the connected sensors should also be checked.
