Description No/too few pulses from the height measurement
sensor when raising or lowering the forks
Error mode No corrective action
Error cause 1. Incorrectly adjusted RV1 potentiometer on A5
electronic card
2. Defective height sensor U10/cables.
3. Incorrect oil quality
4. Fork carriage too light (forks missing)
5. Defective electronic card A5
Comments
1. Turn the potentiometer RV1, on the A5 electronic card, anti-
clockwise and increase the flow on the valve until the correct
lowering speed is obtained.
2. Height sensor U10.
- Check whether the LeDs LD301 and LD302 flash when the forks
are raised or lowered. Flashing is irregular, as the pulses are
phase displacement by 90 degrees.
- If LD301 and LD302 are switched off the entire time, check that
the +15 V supply voltage is on U10. The red cable is positive and
the black cable is 0 V. If there is no voltage: check that the cables
are intact and that there is no play or oxidisation on the connector
pins on terminals X28, X16 and X14.
- If flashing only occurs sporadically, check that the wire does not
slip on the height sensor's roller.
