Otolift Type 87 87 Stairlift Manual

The Otolift Type 87 is a stairlift system designed for use on staircases. It features a closed-loop control system for controlling the synchronous motor and DC brake. The lift is equipped with an on-board charging circuit for charging the batteries. This model includes a buzzer on the PCB and a LED in the armrest to report failures to the user, and a display on the PCB for reporting failures to the mechanic or installer.

Frequently asked questions

The chairlift has several safety features, including a swivelseat switch, an armrest switch, an overspeed governor, an endswitch, safety drive units, safety footrests, and a safety chairframe.

To program the chairlift, you will need to use a service box and follow the steps outlined in the manual. The chairlift must be programmed while moving to the right, seen from the user's position.

The display on the PCB shows various error codes that can indicate a problem with the chairlift. Refer to the manual for a detailed explanation of the error codes.

To reset the chairlift after an 8888X error, you must operate the lift left or right for 10 seconds. When the fast beep stops, the error is reset.

User questions

Q O

Robert Q.

How to install chairlift endpoints?

No votes
  1. Identify the chairlift's top and bottom stop locations. 2. Attach the safety-cap endswitches at these points. 3. Connect the endswitches to the PCB using the wiring diagram. 4. Verify the chairlift stops when the endswitches are activated.
U Z

Robert U.

Is it possible to program the Otolift Type 87 without the device box?

No votes

Programming the Otolift Type 87 typically requires the service box, as described in the manual. Alternative programming methods without it are not specified.

L B

Mary L.

What happens when the safety drive unit on the right side is controlled?

No votes

When the safety drive unit on the right side is controlled, the chairlift's movement is restricted to the left direction only.
