8.3) Other safety devices
a) Electrical and mechanical limit stops
The electrical limit switches (Fig. 18/a) fitted to the lift
allow it to be stopped automatically in the correct posi-
tions at each end of the stair.
In case of problems, a safety overlimits stop device halts
the lift - Fig. 18/b.
CAUTION: in this case the lift remains locked
out of use and an authorised VIMEC technician must
be called in to put it back into service.
b) Power supply
The stairlift is supplied at 230 V A.C. single-phase, while
the auxiliary circuit is supplied at 24 V D.C.
c) Controls
All controls are of the “dead man” type (the lift stops if
the finger is taken off the button).
All the control stations (on the lift and at the floors) are
enabled by a removable key (no-one can use the lift if
the key is not inserted).
CAUTION: Pressing two buttons simulta-
neously, whether on the board on the lift or the
board at the floor, is strictly prohibited.
CAUTION: Never use the lift if the controls do
not work in the “dead man” mode.
d) Operation by hand.
The lift can always be operated by hand to bring the
person being transported to a floor in case of a power
black-out or a failure of the system (See point 7.5, it is
advisable to operate towards the lower floor).
e) Irreversible drive
The worm gear and spiral gear wheel ensure that the
stairlift cannot descend under its own weight and allow
smooth stopping.
f) Motor brake
The electric brake fitted on the motor ensures quick
stopping and stability.
g) Emergency stop button
The lift is fitted with a red mushroom-head emergency
STOP button (Fig. 2/e) which stops all stairlift move-
ments when pressed.
Lift operation is restored by turning the same button
through 45°.
CAUTION: Check monthly that the emergency
STOP button is working properly. If the STOP but-
ton does not halt lift movements, DO NOT USE the
lift! Call in an authorised VIMEC technician imme-
diately.
9) MAINTENANCE
The stairlift has undergone rigorous testing, but VIMEC
advises you to have it checked by technicians regu-
larly.
To ensure optimum service and safety, the system must
be inspected regularly by our specialist technicians, who
will carry out all the procedures described below.
CAUTION: In all cases, call in only staff au-
thorised by VIMEC for servicing and repairs; use
only original spare parts.
CAUTION: The recommended maintenance
frequencies must be complied with.
9.1) Parts requiring regular inspection
Skill level: OS - Specialist operator authorised by
VIMEC.
CAUTION: Disconnect the power supply be-
fore starting maintenance, by turning the Master
Switch to OFF.
Then padlock the box containing the Master Switch.
Six-monthly checks:
a) Safety devices
Check that on contact with an obstacle, the anti-impact
and anti-shearing sensors stop the lift and allow it to be
started in the opposite travel direction.
Check that the stopping positions at the floors provided
by the limit switches are to requirements.
b) Electromagnetic brake
The electromagnetic brake on the motor must stop the
lift when fully loaded before the overlimits stop device
is tripped. If necessary, replace the whole brake.
c) Drive mechanics
Check that the teeth of the drive sprocket and the nylon
wheels on which the lift runs are not worn or damaged.
There must be no grooves or flattening on the wheels.
Check the chain and its stretcher device for wear.
d) Safety gear
Check that the hook device is free to operate without
friction or excessive backlashes and that it trips the
safety microswitch correctly.
To check operation of the safety gear, proceed as fol-
lows:
- Move the stairlift 1-2 metres from the floor.
- Disconnect the power supply by turning the master
switch to OFF.
- Remove the protective panel (Fig. 1/b).
- Press the safety ear hook with a wooden/plastic rod.
CAUTION: Keep well away from all un- pro-
tected moving parts.
- Restore the power supply and press the down button
until the hook engages. The stairlift will stop when the
safety microswitch is pressed by the hook.
- Reset the safety gear by moving the stairlift upward in
manual mode (see point 7.5).
e) Stability of the rail
Check all the fixing screws o the connections to the
mounts and all expansion plugs present.
