Seat swivel switch

Description

The stair lift has a safety feature so that when the seat is not in the correct position for traveling it will not move. This code indicates that the seat is not in the correct position to operate.

Solution

Check the seat is locked in the ride position (the back of the seat should be against the wall the lift runs up).

Note: Models with perch or stand on option require the arm to be in the fully down position before operating.

Seat in ride position
Sit on the lift, press the swivel lever and turn the seat a few degrees then twist the seat back into the correct position.

Seat not in ride position
Press the seat swivel lever and turn seat so it is in the ride position (as stated above).

If you have attempted the above and the code is still showing the micro switch which senses the position of the seat may be jammed or needing adjustment

Seat Swivel Switch Adjustment

If seat is locked in correct position (facing across the stairs) and the diagnostic lights on the armrest are showing a steady yellow light or the LED display is showing a '4', the seat swivel switch is showing an open circuit.

It is likely that the seat swivel switch (fig.1) needs to be adjusted.

The circuit needs to be closed (the switch depressed) to allow the lift to operate. With optimum adjustment the switch will be depressed by the seat cotter pin (fig2) when the seat is in the correct locked position.

When the seat is swiveled, the switch is released, thus disabling the lift (fig.3)

To adjust the switch, remove the seat assembly and plastic index plate cover, if fitted. Loosen the 15mm lock nuts on the barrel of the switch (one either side of the index plate) and reposition, so that 5 or maximum 6 threads are visible above the upper lock nut and tighten the lower lock nut.

Refit the plastic cover and seat. Check that the switch is depressed correctly when seat is locked in correct position.

This completes seat swivel switch adjustment procedure.
