CTH does not raise and lower – No Limit Switch

Print out version available here
In this scenario, the ceiling hoist LCD displays “No Lim_Sw!” and the audible alarm will continuously beep while the ceiling lift has power
If the switch has become detatched from the PCB port, the LCD will dispay “No Lim_Sw!”
Plug the limit switch cable back into the PCB

Has this resolved your issue?(Required)
Inspect the full length of the limit switch cables and connection points.
The limit switches must be removed to fully inspect the wire condition.
Replace the limit switch assembly.
Has this resolved your issue?(Required)
Test the limit switch rollers by pressing them in and out.
Place your ear close to the switches while testing – if the rollers are working, you will hear the switches click “ON” and “OFF”.
Make sure to test both rollers individually, if you dont hear both switches click “ON” and “OFF”, the rollers are jammed/damaged.
Replace the limit switch assembly
Has this resolved your issue?(Required)
