Do not bend or warp the opto edges. The opto edges
should never be subject to torsion forces.
The opto edges should be at least 5 cm from the front
edge of the elevator cabin.
The connection cable should not be under tension and
should not be crushed.
The connection cable should be well laid and secured.
It should not be in continuous motion or rub against
other objects.
Avoid dirt and scratches.
Fasten the opto edges securely with the screws
provided. If need be, the screws can be secured against
loosening using the usual methods.
Ensure that the emitted light beams of one system are
not directed at the receiver edge of another when using
several light curtains close together. Light curtains
can influence each other under certain circumstances.
The emitter and receiver edges must be arranged on
alternating sides in through-loading elevators for this
reason.

Alignment of multiple light curtains
The opto edges are provided with double-sided adhesive
tape to aid installation and fixing for both flush mounting
and surface installations. These should be used in
conjunction with screws.
For installation purposes, we recommend either the
CEDES
flush mounting kit
or or its
surface mounting
counterpart
. These make installing the opto-edges quick
and easy and their side covers help prevent reflection (see
also Chapter 6.3 and 6.4).
6.2 Installation system control rack
The system is located in a control cabinet and is fixed to
the cabin roof with the 4 screws provided or the 2 support
strips included in the delivery.
It is imperative that the following be observed:
Connections K18, K20, K22 and K24 should be
actuated with the positive signal pole (with direct
voltage), connects K19, K21, K23 and K25 with
the negative pole (see Chapter 7, Connection
configuration).
The latch solenoid / motor is operated by the controller.
The vibration should be reduced as much as possible
and the installation should be stable and rigid.
The cable inlet sleeves should be used correctly for
IP54 density. The four rubber packing glands on the
right side are for the connection cables for the opto
edges, the four cable screw fittings on the left being for
the elevator control system connection cables.
Do not plug in or unplug any energized connection
plugs into the control unit plug-in. The device or the
opto edges can be destroyed.
The elevator control system can not be capable of
generating or influencing internal call signals.
No external call signals should be linked to internal call
signals.
The system must be grounded. The “earth” connection
should form a low-resistance connection ≤(10 Ω)
with the ground. Correct grounding of opto edges is
achieved automatically during installation.
6.3 Flush mounting kit
A guard plate is mounted on the inside of the cabin. The
opto edges are mounted on the outside of the cabin
(CEDES Part No.: 100 847).
6.4 Surface mounting kit
If there is not enough space on the outside of the cabin
for the opto edges to be mounted there, they can also
be installed on the inside of the cabin using the surface
mounting kit. There is a loss of approximately 10 cm from
the elevator cabin opening (CEDES part no.: 100 848).
Each mounting kit comes with a detailed manual
