CS SERIES
Fill Solenoid Cycles On and Off
CS SERIES Control System features a timer function whereby the valve open duration
is limited, allowed to shut for a short warm-up and then opened again. To confirm
or change the valve open duration:
• Select MENU, USER OPTIONS, CONTROL OPTIONS, FREEZE-GUARD
OPTIONS, VALVE OPEN DURATION.
If the controller Freeze-Guard function detects that the valve is stuck in the open
position (i.e., continues to fill after the valve is de-energized), it will attempt to De-
Ice the valve by causing a rapid cycling of the valve in an attempt to dislodge the
blockage.
• To activate or de-activate this feature: Select MENU, USER OPTIONS,
CONTROL OPTIONS, FREEZE-GUARD OPTIONS, VALVE DE-ICING.
Repeated cycling of the Solenoid Valve, caused by excessive turbulence, power/low
battery, bad connection, or circuit board corrosion, could be attributable to moisture
invasion on the controller circuit board.
To troubleshoot proper operation of the fill valve:
1. Check gasket seals.
2. Access control board and allow time to fully dry prior to reinstallation.
3. Confirm the pressure of the supply vessel is less than 22 psi (1.4 bar/138kPa).
4. Watch the interface panel on the controller to verify if the Start and Stop Fill
cycles are repeating. You should see and hear each cycle.
Fill Solenoid Makes Excessive Humming Noise
During normal operation, the fill solenoid valve will make a soft humming noise. If
the noise is excessively loud, turn the fill valve on and off using the control panel. If
a soft humming noise is heard, the valve should continue to operate reliably. If the
humming noise is excessive, replace solenoid valve. You should change the solenoid
valve every 3 years.
Display = “Check”
The word CHECK will flash during periods of Splash-Guard protection.
Lid Open Alarm
A lid switch is located near the front hinge. The proximity switch should actuate when
the hinge is opened and again when it is shut.
• Confirm that there is a ½ in. (12 mm) gap between the sensors.”
