6. TROUBLESHOOTING
Check the following if the lift will not operate:-
•
Open and close the door. Ensure it is fully closed and locked.
•
There are no obstructions under the lift.
•
There are no obstructions on top of the aperture trap board.
•
Turn the key-switch if fitted.
(Please note there is no specific on or off position)
• The orange light on the power supply unit is illuminated.
(Refer to Section 6.1.)
6.1. Electrical Power Failure
The orange light on the right hand side of the power supply unit is illuminated when there is mains
power to the lift.
(Reference page 7)
If the orange light is not illuminated check the following:-
•
The lift isolator switch is on and the fuse is ok.
(This should be located near the lift)
•
The main distribution lift circuit breaker and RCD are both switched on.
In the event of a power failure the lift has a battery back-up feature that enables the following
features to operate: -
•
Lift lights
• Lift alarm
• Door operation
• Descent using the in-car emergency lowering button
• Lift safety edges.
Please note the self levelling device will not function
(refer to note below)
in the event of mains power
failure. A ‘Shoot Bolt’ safety device restricts the distance the lift can creep down when the lift is at
the first floor position. If the lift is left for a long period of time with no mains power, it will stop on
the shoot bolt and can NOT be lowered by either the battery backed emergency lowering, or the
manual emergency lowering. The lift can only be re-used when the mains power returns.
The lift is fitted with a self-levelling device. When the lift is left at the upper level it will gradually
creep down a maximum of 25mm, the lift will then automatically re-level to the upper level. If the
lift creeps up when at the upper level, it will automatically re-level down to the upper level.
