CTH does not traverse

Print out version available here

In this scenario, the CTH has power and performs the usual lifting and lowering actions, but does not respond to traversing commands from the handset.

Are the CTH wheels slipping in the track?(Required)

Inspect the internal profile of the track to see if the wheels are spinning during traverse commands. Inspect the track for any swarf, debris or liquid which may be causing the slippage.

Inspect the track system to ensure it is level, the ceiling lift will struggle to traverse if the system is not horizontal.

If the track is not horizontal, then refer to the installation manual on how to set the track system correctly.

Is the handset damaged?(Required)

The handset traverse buttons or air tubes may be damaged/leaking.

Plug the drive/traverse motor cable back into the PCB

Is the drive motor cable damaged?(Required)

Inspect the full length of the drive motor cables and connection points.
