B. Wheelchair continuously drives slower than normal
Cause
Possible solution
Speed limit due to
microswitch signal from
seating function.
Check if all seating options are in neutral
position.
Measure resistance from the speed limit cable in
different seating positions. Bad cable connections
or a broken resistor influences the drive inhibit
signal.
Incorrect programming
Check for correct program. Re-program if
needed.
Parking brake partially
engaged
Check parking brake function. Clicking sound at
engaging/disengaging should be present. Check
temperature of parking brake after driving.
C. Wheelchair drives slower throughout the day (or after several hours)
Cause
Possible solution
Poor batteries
Check batteries and battery voltage.
Poor or incomplete battery
charging
Check battery charger.
Check charging duration with the user.
Thermal rollback
(overheating)
Check usage of wheelchair, extreme usage
can cause the power module to decrease the
maximum currents for protection.
Check wheelchair in freewheel mode for extreme
resistance on rolling or turning.
Check Gyro cabling and/or replace Gyro module.
D. Wheelchair only drives well for a short period of time
Cause
Possible solution
Current limit is set too
low or the controller is
underspecified
Check program settings and/or replace controller.
E. Wheelchair can be powered up, but does not drive
Cause
Possible solution
Parking brakes are in
freewheel mode (flash code
on remote)
Set parking brakes to Drive mode.
Drive inhibits active (flash
code on remote)
Check program which Drive inhibits are present.
Check cabling of Drive inhibits on wheelchair.
