General description

The opto edges are connected to the control unit
plug-in after installation. The plug with the blue
marking (receiver edge) is inserted into the "re-
ceiver" socket, the plug with the white marking (emit-
ter edge) being inserted into the "emitter" socket.
The plugs are coded and cannot be inserted incor-
rectly or in the wrong sockets. Ensure that both of
the plug's safety jacks engage correctly.
The plug can be removed again by pressing the two
safety clips. The final step is connecting the connec-
tors (K28...K34) (observe connection configuration).
It goes without saying that opto edges should al-
ways be connected in pairs to each of the control
unit plug-ins in cases of through-loading elevators.
The plug-in system controller and the control unit
plug-ins are controlled by their own microproces-
sors. These test the entire system after activation.
The following procedures occur during this:
The following symbols appear consecutively on the
plug-in system controller :
For elevators with one
entrance:
For through-loading
elevators:
A bar then circles around on the display until the
self-test is completed. An F or U appears if the test
is successful, depending on whether the light curtain
is bypassed or not.
The LED "Alarm T" and "Alarm R" flash alternately
with approx. 1 Hz for approx. 10 seconds on the
control unit plug-in while the self-test is in progress.

Both LEDs subsequently illuminate continuously for
approx. 2 seconds. The light curtain is calibrated
during this time period. The two LEDs "Alarm T"
and "Alarm R" are then extinguished. The relevant
control unit plug-in and associated opto edges are
now ready for operation. Both control unit plug-ins
undergo this procedure in the case of through-
loading elevators.

Installation check

Important safety notice:
The items listed in this section are relevant to safety
and must be checked when accepting an elevator.
Failure of the installation conducted to match the
points below should be adjusted immediately.
The distance between the sensors and the
front edge of the cabin is 100 mm (tolerance
±50 mm).
The lowest sensor is 30 mm from the cabin
floor.
The height monitored is at least 1500 mm.
The sensor grid is ≤ 250 mm.
The danger zones are marked with black and
yellow.
Both sensor connection cables are conveyed
upwards away from the cabin.
The system control rack is correctly grounded
≤ (10 Ω)

Function test

Correct integration of the cegard/Lift should now be
checked. These tests should be conducted during
the initial installation and after every elevator inspec-
tion. They help the elevator technician check the
wiring and correct operation of the unit.

7.3.1. Test procedure

Individual procedures are approached step by step
during the test. It is important that the sequence
described be adhered to, as the desired points may
on
otherwise not be tested in certain circumstances.
off
Any error resulting in the failure of a test point
on
should be remedied and the procedure should be
recommenced from the first test. A minimum of two
off
t
people are required to conduct these tests. (one
3
person in the cabin, one person outside (e.g. care-
taker)).
Notice:
No third person or any other object should be in the
elevator during commissioning or inspection!
