Service Procedure #10 - Replacement of Vertical Motor

Disconnect the main connector from the circuit board.
3)
With an extracting tool (#005.00374), remove the
two vertical motor wires from the main connector,
position numbers 11 and 12 (see Fig. 40).
4)
Put a mark on the back of the motor housing to

Remove the 2 screws on the back of the motor using
a M8 hex socket and pull the motor assembly out
(see Fig. 41).

Position the motor plate into the side grooves. It is very important to position the motor housing in the same
orientation as it was prior to disassembling, i.e. that the mark is positioned upward (see Fig. 41), and making
sure that the contact point of the wires inside the motor are placed above the shaft (see Fig. 42).
•
Plug the motor wires into the main connector making sure to place the red wire into position #11 and the blue
wire into position #12.
Note: If any of those three directives are not respected, this could result in an inversion of the Up/Down commands.

m) to secure the motor in place.
8)
Reassemble the lift by performing service procedure #9.
9)
Before putting the lift back in service, perform a weight load test: Attach a weight equivalent to the ceiling lift’s SWL
to the spreader bar, refer to the specifications sheet of the ceiling lift user’s manual or the label on the lift to determine
the SWL rating. Press the UP button to verify if the unit can lift the load up until the strap is fully wound. Lower the
weight and remove it from the spreader bar.
