Installation of Opto Edges

When installing the opto edges the following has to
be observed:
 The emitter and receiver should not be rotated
180° when mounting. That means, the
connection cable of the door edge must come
out of the top (figure 5).
Figure 5: Arrangement emitter / receiver
 The opto edge must be min. 5 cm away from
the shaft wall.
 No strain to be put on the connection cable and
it may not be crimped or pinched.
 The connection cables should be well fastened
and guided. They may not move or rub for any
length of time.
 Avoid dirt and scratches.
 The opto edge should be well screwed down
with the screws supplied. In case of emergency
the screws are secured against loosening with
the usual methods.
 When using multiple light curtain systems near
one another, no emitter beams can be emitted
in the direction of another system's receiver.
The light curtain systems could interact with
one another. For elevators with door openings
at both ends of the cabin, the emitter and
receiver door edges of the two doorways
should therefore be arranged alternately to one
another (figure 6).
The opto edges come with sections of double-sided
adhesive tape, which can be used as a mounting aid
and as a damper to reduce vibration, both for
recessed mounting or surface mounting. For the
mounting we recommend the CEDES mounting kits
and drilling template, which considerably simplifies
the installation of the door edges and helps to reduce
reflections.

4.2. Mounting of the control unit light
curtain
The control unit light curtain is mounted anywhere on
the roof of the elevator cabin using the screws.
Please note that:
 when mounting the housing of the control unit
light curtain is electrically connected to the
elevator cabin (earthed).
 vibrations are reduced as much as possible
and a stable mounting is ensured.
 The opto edges and connection plug are not to
be connected and disconnected to the control
unit light curtain while it is receiving power.
Otherwise the control unit light curtain could be
destroyed.

Mounting kit 'Recessed mounting'

In this type of mounting, the door edges are installed
behind the walls of the elevator cabin. The drilling into
the cabin walls is performed using the drill and the
drilling template provided. Afterwards, the drilling
template serves as a fastening plate for the infrared
permeable cover. The mounting of the opto edges is
also carried out through the elevator cabin wall from
the inside of the cabin.

Mounting kit 'surface mounting'

The guard plate is made out of stainless steel V2A, is
painted yellow and black and comes with all
necessary mounting parts.
