J. Wheelchair wobbles overall or moves up and down when driving
Cause

Possible solution

Drive wheels have radial

misaligned tyres. Can be

caused by long (weeks)

inactive periods

Check for misalignment of tyres. If misaligned,

reduce tyre pressure to 1 bar, drive for several

minutes at moderate speed and increase

pressure again to advised value.

Misalignment can be reduced this way. If not

sufficient replace wheel.

K. Seating actuator does not function
Cause

Possible solution

Current setting is not correct

Check programming and make corrections

if needed. Contact manufacturer for correct

settings.

Cables not connected or

cables damaged

Check cables and replace if needed.

Wheelchair goes into fault

status when actuator is

operated

Actuator has a short circuit that becomes active

when the actuator is operated.

Replace actuator.

Actuator inhibit is active

Check program to see what actuator inhibit is

present.

Check if inhibit signal is functioning correctly

(example: with lift and tilt to maximum, recline

will no longer move backwards).

Actuator module (output)

fault

Try actuators on different output channel to

check what output channel has a fault.

L. Seating actuator only functions for a short time
Cause

Possible solution

Maximum current setting is

too low

Check programming and make corrections

if needed. Contact manufacturer for correct

settings.

Actuator time out setting is

too short (or actuator speed is

too low)

Check programming and make corrections

if needed. Contact manufacturer for correct

settings.

Actuator is internally not

functioning properly

Check actuator temperature after operation and/

or check for excessive noise when operated.

Replace actuator.

Seating mechanism is moving

poorly or with extreme

friction

Check mechanisme on loose bolts, cracked or

bent parts. Replace parts or modules.

M. Seating actuator moves in wrong direction (after replacement)
Cause

Possible solution

Wiring connections possibly

twisted in cable or motor

Change actuator direction in driving program or

replace cable or part.
