Code
Meaning
No Display
No power
1. Check the battery isolator switch is in the ‘I’ position.
2. Check batteries are correctly connected and in good order.
3. Check 7.5 Amp data line fuse and 20 Amp fuse.
Platinum
OK
The stairlift is on charge and everything is OK, lift should operate normally.
Safety Circuit / Final Limit
Final Limit Fault/Safety Circuit short to 0v (ground)
1. Check key switch is on connected and working.
2. Check seat swivel switch is connected and working.
3. Check if the stairlift has over-run and switch is connected and working.
4. Check if OSG and safety gear has actioned and switch is connected and working.
Low Battery
Batteries Need Charging
Stairlift batteries are down to 21V.
1. Check transformer is plugged in to mains socket and turned on.
2. Check charging point voltage is present unloaded and loaded.
3. Check charge voltage is present on white charge connector on main PCB.
Off Charge
Lift is off Charge
Stairlift batteries are not charging (the stairlift may still work). To charge them:
1. Move the stairlift to a charging point.
2. Check transformer is plugged in to mains socket and turned on.
3. Check charging point voltage is present unloaded and loaded.
4. Check charge voltage is present on white charge connector on main PCB.
5. Check 7.5 amp fuse on PCB
End Stop
End Stop Activated
Ensure that both track and staircase are clear of obstructions.
Safety Edge
Lift stopped by safety edge in direction of travel (footplate or side cover)
Ensure that both track and staircase are clear of obstructions.
Move Right
Lift travel direction
Right.
Move Left
Lift travel direction
Left.
Seat Swivel
Seat in Swivelled position
Lift cannot move until powered swivel seat is returned to travel position.
1. Check powered swivel option is selected in menu (if you have a powered seat).
2. Check lift is set as correct hand in menu.
3. Check lift is at top of track and bottom skate end stop is activated.
4. Check transformer is plugged in to mains socket and turned on.
5. Check charging point voltage is present unloaded and loaded.
6. Check charge voltage is present on white charge connector on main PCB.
Thermal Cut Out
Motor and motor drive are running too hot, overloaded lift or excessive use.
Switch lift off and allow motor to cool.
Call Conflict
More than one conflicting call received.
Direction toggle or wall control direction button stuck on.
Release Joystick
Conflicting call received.
User needs to release joystick and re-input call.
Brake Fault
Motor brake inoperable.
Reset lift. Check brake connection on main PCB and reset lift.
Relay Fault
Power relay did not close
Check battery charge level. Reset lift. Tap Relay. If problem persists, renew PCB.
There are also 3 thermal fuses on the PCB. If any of these fuses are activated, a red LED located nearby
will light.
This generally indicates a wiring fault on one of the circuits connected to the PCB in the surrounding
area to that LED.
Hinge
Hinge arm is not fully down
Check hinge arm is fully down. Run lift upwards to intermediate or top charge point and allow hinge to
lower on downwards call.
Check Hinge interlock circuit for operation.
