Troubleshooting:
Operation of the Hallco LIVE FLOOR
TM
depends on a functional and adequate hydraulic
supply system, a working hydraulic module, intact and correct external plumbing, and a
correctly operating control valve. This document covers the potential failure modes of the
electric solenoid control valve only. Refer to the floor owner’s manual for additional
troubleshooting information. Contact Hallco if the troubleshooting techniques do not resolve
the floor malfunction.
The table below shows all the possible control valve combinations, and the expected floor
movement associated. Three of the combinations produce standard operational floor
movement and three produce incorrect movement. Compare the configuration of the desired
floor movement with the configuration of the actual floor movement to identify a suspect
solenoid valve.
Each cartridge valve has a manual override option. For normal mode make sure that the
manual overrides of SV-1 and SV-3 are not locked in the override position (out). Operate the
floor with the manual controls to check whether the problem is electrical or hydraulic.
If the floor operates correctly when the valve is controlled manually, then the problem is not in
the solenoid valves. A valve coil may be malfunctioning or not energized correctly. Coils may
be swapped between valves to verify which one is malfunctioning.
If the floor does not operate correctly when it is manually controlled, the problem is likely not
electrical. SV-1 and SV-3 valves may be swapped to verify which one is malfunctioning.
