5.7.9 Door stop switch
5.7.9.1 Sliding door:
The sliding door is closed by pushing the actuator into
the door guard locking switch (Fig. 10). The switch is
unlocked by pushing the green button if the cabin is
located at a height corresponding to a platform. In
case of an emergency evacuation between platforms,
the interlock is unlocked by pushing its emergency
release red button from outside the cabin as well as
using an M5 triangular key from inside the cabin.
5.7.10 Trapped-key interlock system (optional):
Control is interrupted by turning the trapped-key
switch to OFF. The key can then be removed. The key
allows the user to open the platform fence doors. See
the Trapped-Key Interlock System Manual for further
information.

At the top of the cabin frame a top obstruction
detection device switch (works as a top limit stop
switch) will stop upward travel when activated (Fig. 11).
Downward travel will still be possible. A top stop bar
which activates the top obstruction detection device
switch is installed below the traction wire rope
attachment.

5.7.12.2 EMERGENCY top limit switch
Deactivates control if the top obstruction detection
device switch fails (Fig. 11). Manual downward travel is
possible.
CAUTION!
Do not use the service lift until the top
limit stop switch fault has been rectified.
5.7.11.3 Bottom obstruction detection device
The bottom obstruction detection device switch (Fig.
12) stops downward travel if the service lift
encounters an obstacle or t o uches the ground.
Upward travel will be possible, for instance to remove
the obstacle. In order to put the service lift on the
ground, the contact plate's operation can be bypassed
with the key switch in the control box.

5.7.11.4 Top obstruction detection device
The top obstruction detection device switch stops
upward travel in case the service lift:
- Type 1: encounters an obstacle.
- Type 2: the switch also works as a top limit stop
switch. A top stop end bar is installed bellow the
guiding wire rope attachment and activates the top
obstruction detection device switch.
Downward travel will be possible, for example, to
remove the obstacle.
5.8 Safety devices for fences with
doors (optional)
Safety devices for fences include devices to prevent
people from accessing the service lift area, unless the
service lift is safe to be accessed. The device also
guarantees that the service lift does not when the
protective fence doors are open. There are two types
of safety devices for fences:
5.8.1 Guard Locking System
The Guard Locking System uses a system of security
locking switches installed on the fences. Another
position switch detects the correct position of the
service lift on the protected platform. The service lift
cannot operate until all the protected fences are
closed and locked.
