All stop switches must work correctly. All stop switches are positioned within the safety chain and when operated
will remove all calls and prevent the lift from moving. The four stop switches in question are in the cabin, the pit, the
test control (landing control panel) and the landing control panel itself.
•
Required action
It is unsafe to leave a lift with no form of emergency communication. If the alarm device cannot be made to work,
then consult customer and report to supervisor that lift may have to be removed from service, with details of
suggested remedial work.
If any of the stop switches are not operational perform any remedial work necessary. If still not operational inform
the customer and supplier that the lift must be taken out of service.
9.9 Safety edges
•
Required standard
A mechanical safety edge is installed on the XL Plus; these are situated at the top and bottom of each door
aperture on the cabin. Activation of all mechanical edges must bring the lift to an immediate stop and drop the lift
call.
•
Required action
Safety edge failure requires the lift to be taken out of service immediately and the requirement to report to
customer and supervisor with recommendations for remedial action.
9.10 Light Curtains
•
Required standard
The light curtains are situated at the sides of each door aperture on the cabin. Operation of the light curtain must
bring the lift to a controlled stop and remove the lift call. The voice enunciator should inform the user ‘Light ray
activated, please keep clear of the entrances’.
•
Required action
Light curtain failure requires the lift to be taken out of service immediately and report to the customer and
supervisor with recommendations for remedial action. If an error is detected within the voice enunciator, inform the
customer and supervisor of any remedial work required and the recommendation of the lift to be taken out of
service.
9.11 Control panels
•
Required Standard
There are two areas to be checked, both the control unit behind the COP (
4.2 Cabin operating panel (COP)
removed, pg 4
) and the controls at the upper floor (
4.3 Upper floor landing controls, pg 4
). Contactors and relays
when energised should not buzz or be excessively noisy. There must be no indications of excess contact wear,
dust underneath relay or flash markings around contactors. Fuse holders must be intact with no damage. Check
fuse rating and remove any discarded/used components or shorting wires. All PCB connections must be of sound
nature and there must be no visible damage to the board.
•
Required action
If a new contactor, PCB or relay is required, record manufacturer, type number, coil voltage, contact arrangement
and inform supervisor immediately. If new fuses required, record rating and physical dimension.
If it is not possible to leave the lift in a safe working order, inform the customer and supervisor and advise the lift
should be taken out of service.
