Mechanical
Pre-Set Overrun
▪ Solenoid blocked and cannot close or has a damaged piston.
▪ Solenoid coil wired incorrectly. Check solenoid orientation.
▪ P-cut setting too low. Adjust P-Cut setting.
▪ Check that configuration is correct for calibration method - i.e., temperature
compensation on or off.
▪ Check that filter is not dirty.
Solenoid Valve Not Opening
▪ Check the output LEDs on the K-Factor board.
▪ Check the electrical supply to the coil. Check the C5000 output triac is switched on.
There should be 220 – 240 volts across the solenoid coil.
▪ Put power on the solenoid and hold a screwdriver above the coil to feel the magnetic
field pull. Because of the construction of the coil a resistance reading cannot be
obtained.
