Refitting / Replacement
Refitting is a reversal of the removal process noting the following points:
•
When fixing the individual switches, fix the black and brown wire block to the back face of the portable
lift first (e-stop side)
•
Route the black and brown wire along the chassis side face underneath motor A.
•
Fix the black and red wire block to the front face of the portable lift (PCB side)
•
Attach the limit switches to the chassis with the four screws but do not tighten.
•
To set the switches, slide a switch inward until it activates against the roller (the switch will click). Once
it has activated, move the switch outward until it releases. (the switch will click again). Once it has
released, tighten the screws to set the limit switch.
•
Repeat these steps for the second limit switch.
•
Manually test the switches are working by pressing the rollers in and out. You should hear the switches
clicking when activated and released.
