What to do if Walther Systemtechnik WDV-01 sensor gives a permanent signal?

  Penny BaileyAug 11, 2025
  If the sensor of your Walther Systemtechnik Control Unit is giving a permanent signal, it could be due to several reasons. First, the sensor might be defective and needs replacement. Another cause could be that the dosing volume is too small, requiring you to check the dosing valve, adjust the dosing volume to a higher setting if necessary, and verify the sensor positions. Finally, excessive grease feed pressure could be the problem. In this case, reduce the pump pressure to the dosing valve's maximum operating pressure, and consider using a material pressure regulator.

  If the valve of your Walther Systemtechnik Control Unit is actuated but no lubricant is ejected, it may be caused by the feed pump not feeding lubricant. Check the feed pump and its venting screw, referring to the feed pump's operating manual for guidance. Another possible cause is leakage in the dosing valve, which should be inspected.

  If the Walther Systemtechnik Control Unit sensor has no signal, there are a few potential causes. It could be due to a broken cable, in which case you should replace the cable. Alternatively, the sensor itself might be defective and need replacing. Another possibility is that the dosing piston is in the starting position. To resolve this, check the pump pressure and inspect the grease supply bore hole for any contaminants.

  To address air pockets in the Walther Systemtechnik Control Unit grease system, which may be due to air in the grease container or tubing, disconnect the tubing to the dosing valve. Drain a quantity of grease and restart the system with the dosage adjustment screw set to maximum.
