8) SAFETY SYSTEMS
a) Safety nut screw
This is a second nut screw that only comes into op-
eration if the main one is no longer engaged with the
lifting worm screw. If the safety nut screw is engaged,
an electrical failure detection system will prevent the
platform from being used until it is repaired.
b) Locks
Use of the platform is only enabled with the correct lock
status; the unit cannot be used if the gates are open or
the locks have been tampered with.
c) Guard board
The platform can be tted with a guard board (Fig.
15/a) which has the dual function of acting as an ac-
cess ramp at the oors (when lowered) and holding
the wheelchair in place while the lift is in motion. The
guard board automatically moves to the safety position
once the platform has risen a few centimetres above
the bottom oor.
The guard board only opens at the bottom oor.
8.1) Other Safety Devices
a) Limit switches and limit stops
The limit switches stop the lift automatically in the lan-
ding positions at oor stops.
b) Anti-shearing/anti-crushing guard
The platform can be tted with a bellows guard on the
open sides.
c) Power Supply
The unit is supplied at 230 V VAC single-phase (50 Hz),
the auxiliary circuit and buzzer are supplied at 24 VDC.
d) Controls
All the controls are of hold-to-run type (the lift stops as
soon as the nger is removed from the button).
A remov¬able key enables the control boards at the
oors. The platform is not accessible until the gates
have been opened (no one can use the unit unless the
key is inserted).
e) Operation by hand
The lift can always be raised/lowered by hand to bring
the passenger to the oor in the event of a system failure
or power blackout. (See point 7.10).
FIG.15
f) Emergency stop button
There is a red emergency STOP button on board the
platform. When pressed, the emergency STOP button
cuts out all lift movements and triggers the alarm sy-
stem.
To restore the lift to operating mode, turn the STOP
button clockwise through 45°.
WARNING: Check operation of the
emer¬gency STOP button every month. If the STOP
button does not cut out all lift movements, DO NOT
USE the lift!!
Call in an authorised VIMEC technician at once.
g) Movement cut-out in the event of obstacles
The platform is tted with a sensor that automatically
cuts out downward movement in the event of obstacles
interfering with the moving parts underneath it.
h) Anti-shearing/anti-crushing photocell barrier
(option)
They detect the presence of an obstacle on the sides
of the platform not equipped with walls, and on the side
between the rail side guard and the column, stopping
its movements.
