Possible causes:
• Power supply faulty
• Power supply board defective
• Control PCB defective
- Check voltage on type plate.
- Check voltage on power supply board
at terminals 0.0 - 0.1 - 0.2.
- Check 24 VDC voltage on control
PCB at terminals 1.0 - 1.1
(without load up to 36 VDC may be
measured)
- Check plug connection/ribbon cable
Possible causes:
• Feed and/or outlet line shut off or
blocked
• Wear
• Control PCB defective
• Solenoid valve defective
- Check feed line and outlet line
- Replace worn parts
- Check if valve opens audibly
(press test button several times)
- Check 24 VDC voltage on control PCB
at terminals 3.0 - 3.1 - 3.2
(without load up to 36 VDC may be
measured)
Possible causes:
• Feed line with insufficient slope
• Excessive condensate quantities
• Sensor tube extremely dirty
• Dropping below necessary minimum
pressure
- Lay feed line with adequate slope
- Install venting line
- Clean sensor tube
- Ensure minimum pressure, otherwise
install low-pressure or vacuum conden-
