Light Sequence Circuit board Problem Action
* * * All 120 boards Controller Powered Down Battery is disconnected or completely drained.
* * * All 120 boards NORMAL OPERATION Batteries fully charged, lift in correct travelling position all power connected ready for use. Unless one of the following has occurred.
Toggle fault Try moving lift using remote control, if lift responds toggle is faulty. If lift does not respond, check safety edges and, finally limit switches. Caution: not all customers are able to perform these checks, if they cannot, ask if there is anyone who can help them.
Safety edges These are safety features that stop the lift if it hits any object. There are three on the footrest and two on the carriage itself. The lift’s location determines which edges have been activated.
Lift at top
To check down safety edges, depress footrest safety edge furthest from stair nose with the heel of the hand then fold the footrest up and depress the center of the underside. Next, run hand up the track until it touches the carriage and depress safety edge found at this point. All safety edges are spring loaded and should move freely.
Lift at bottom
To check up safety edges, depress footrest safety edge closest to stair with the heel of the hand, then run hand down the track until it touches the carriage and depress the safety edge found at this point. All safety edges are spring loaded and should move freely.
Lift mid track
Check all safety edges
Limit switches (up/down/final) These switches ensure the lift stops steadily without a jolt, by making contact with stops at each end of the track.If the switch fails the final limit will be activated. The switches are located under the carriage just above the rail and are made of brass with a small wheel on each of them.
Lift at top
Look down the track from above the lift. If the left hand switch is raised the lift will think it is at the bottom hence it will not travel down the track. Push the left hand switch down with a screwdriver, so it is level with the middle switch.
Lift at bottom
Look down the track from above the lift. If the right hand switch is raised the lift will think it is at the top hence it will not travel up the track. Push the right hand switch down level with the middle switch as suggested above.
Lift mid track
All limit switches should be level (fully extended). If any of the switches are raised push switches level as suggested above.
* * * All 120 boards STANDBY MODE The green LED will only flash if the lift is left off-charge or on its charge point not receiving any mains power. The lift is in standby mode to save battery power.
Lift mid track
Send the lift to a charge point. If it does not respond, follow procedure for constant green LED.
Lift on either charge point
All LEDs will flash and the lift will bleep for 40 sec before the green led flashes on it’s own. Ask customer to check the transformer is plugged in and switched on. If so, request they check the socket with another electrical appliance. This will ensure the lift is receiving a charge.
* * * All 120 boards OPEN CIRCUIT Ascertain type of board in lift in order to follow correct procedure, as infra red boards have different software to radio boards. Look at the remote controls for three small bulbs in the end, this will determine if the board is infra red. If there are no bulbs the board is radio.
V5 Infra-red Key switch Check the lift is switched on at key under the control arm. Try and pull the key out of lock. If it does not pull out the lift is switched on. If it pulls out, place the key back in the lock and turn it clockwise. If the red LED does not go out, it requires a visit by an engineer.
V4 & V5 Radio OPEN CIRCUIT The red LED will light up if either the lift is switched off, the seat is not in the ride position, the seat swivel micro switch is not connected correctly, the over speed governor (OSG) has been activated or the lift has over ridden the top/bottom stops. Check the following in the order below.
Key switch Check lift is switched on at the key.
Seat swivel Check the seat is locked in the ride position (the back of the seat should be against the wall the lift runs up).
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).
OSG / Final Limit Check position of footrest against the level of the upper floor. If it is below, follow procedure for OSG and if it is above follow procedure for final limit.
Over Speed Governor
Locate the hand-winding wheel (gray mushroom shaped object approx. 5" in diameter, generally left under the rail on one of the stair treads). Prise out white disk on the carriage next to the red plug (a blunt knife or screwdriver may be required). Place hand-winding wheel into the hole and turn the wheel clockwise maximum of ten turns until the red LED goes out and the green one comes on. Take the hand-winding wheel out of the hole and send the lift to the top of the rail and run it back down again just to check everything is ok.
Final Limit
You will need the hand-winding wheel for this also, but instead of winding the lift up the track, wind the lift down the track (turn the hand winding wheel anti clockwise). Take the hand-winding wheel out and run the lift down the track and back up to check the lift is ok.
* * * All 120 boards OPEN CIRCUIT, STANDBY MODE The red LED will only flash if the lift is broken down and not receiving a charge. If lift was on charge point when red LED flashed, ensure transformer is plugged in and switched on. Follow procedures for red constant LED.
* * * V5 Infra-red,
V4 & V5 radio		 Lift not receiving charge All lights will flash and the lift will bleep for 40 sec then stop. If the lift is moved, the sequence occurs again. Ascertain location of lift
Lift not on charge point
Send lift to either charge point
Lift on charge point
Check transformer is switched on and plugged in. Check socket with another electrical appliance. If all is ok, send lift to other charge point in order to check it is not just a fault with one of the charge points. If still flashing and bleeping it requires a visit by an engineer.
* * * V4 & V5 radio Seat swivel Seat not in ride position or micro switch is jammed. Check the seat is locked in the ride position (the back of the seat should be against the wall the lift runs up).
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).
* * * V4 & V5 radio Batteries isolated Check that the red plug is fixed into the carriage correctly. If not insert. If connected correctly ask customer to pull out and replace. If it will still not go, requires visit by an engineer.
V5 Infra-red OSG OverSpeed Governor has been activated. Locate the hand-winding wheel (gray mushroom shaped object approx. 5" in diameter, generally left under the rail on one of the stair treads). Prise out white disk on the carriage next to the red plug (a blunt knife or screwdriver may be required). Place hand-winding wheel into the hole and turn the wheel clockwise maximum of ten turns until the red LED goes out and the green one comes on. Take the hand-winding wheel out of the hole and send the lift to the top of the rail and run it back down again just to check everything is ok.
* * * V5 Infra-red,
V4 & V5 radio		 Batteries flat Lift has been run until battery is flat. Lift will attempt to reach charge point at half speed and then charge for 40 minutes before moving again
* * * V5 Infra-red Batteries low Charge in batteries is less than 30 percent. This will only occur when the lift is toggled. Park lift on charge point and leave for a minimum of 40 minutes.

The following fault codes give an indication of what is wrong with the lift. The LEDs flash red/yellow four times then the following fault codes four times then red/yellow again. All version 5 boards including infrared should reset themselves once the lift is toggled.
