Depar
4. If there is NO audible click from the solenoid, check the
voltage to Pin #s 14, 15, 16 and 17 of terminal block J13.
While still in RUN mode, use a reliable multimeter to measure
the following DC voltages on the circuit board. Use J8 pin
#38 as a groun
TERMINAL # VOLTAGE
J13 #14 12.0VDC ±1.5VDC
J13 #15 1.0VDC ± 0.5VDC
J13 #17 12.0VDC ±1.5VDC
J13 #18 1.0VDC ±0.5VDC
5. If the above voltages are correct, this may be an indication of
a problem with the valve or its associated components.
Contact your local Liquid Controls Service Center or the
Liquid Controls Service Department for assistance.
6. If the above voltage are NOT correct, replace the following
components with known working units until the problem is
resolved:
Solenoids* Varies depending on system.
