cegard/Lift LI

11. Regulations

Constant and safer operation can only be
guaranteed, if the following points as well
as the connection and limit values in this
operation manual are observed by those
carrying out installation, the maintenance
company and the operator. If this is not
achieved, operation of the system is not allowed.

11.1 Legislations and directives

The installation company, the service company and
the operator have to take into account the national and
local legislations as well as the directives of the elevator
manufacturer, so that cegard/Lift LI fulfills and constantly
maintains its safety function for the operator.

11.2 Qualified technical personnel

The mounting, implementation and maintenance of cegard/
Lift LI may only be carried out by specialists, who can prove
an appropriate education in safety methods in elevator
equipment. The control unit light curtain has to be installed
so that unauthorized individuals do not have the possibility
to alter the wiring. This is carried out by mounting it on the
elevator cabin roof.
Before the elevator is put into operation, it is important to
check whether the light curtain corresponds to the entire
area needing to be monitored. For this, the built-in buzzer
in the control unit plug-in can be turned on which signals
the interruption of each of the light beams.
For the testing, for example a black plastic tube with a cross
section that corresponds to the resolution of the opto edge
and a length of at least 200 mm can be used.

11.3 Regular testing

cegard/Lift LI has to be checked for correct function at
every elevator service. The service technician must test
whether the light curtain covers the whole monitored
area using the corresponding testing piece (e.g. using the
integrated buzzer).

11.4 Reflection

Even a very precise calibration, as which takes place in
the control unit light curtain, cannot always prevent every
reflection. Extremely reflective shaft walls (tiled or metal
plated) which run parallel to the monitored area or also
too short a distance between the emitter and receiver
edges could cause reflections. If a is not possible, the
reflection has to be reduced by appropriate means. This
can be carried out e.g. by using the recessed mounting kit
(Chapter 6.3), using a matt black paint, by sandblasting or
by applying a lens aperture or by increasing the distance
to the shaft wall.

11.5 Cleaning the opto edges

The cegard/Lift LI is an optical device. Therefore the opto
edges should be cleaned with a soft cloth and with soapy
water if very dirty. Under no circumstances may solvents be
used. This could lead to the opto edges being damaged or
operating range being lost.

11.6 Protective circuit

The safety circu it of cegard/Lift LI must fulfill the following
requirements:
 It must prevent a journey, respectively the equipment
must be completely stopped, if an invalid intrusion
into the protected zone is detected by the light curtain
(opening of the safety circuit).
 The system must be bypassed for running-in and
readjustment purposes.
 Stored journey commands do not need to be deleted at
a reaction of the safety device.
 If the safety device has interrupted a journey, once the
protective area is no longer interrupted, the journey
may only be continued after a renewed travel command
from inside the cabin (pressing of the desired floor
button) has been given.
 An impairment of the safety directive by a failure
in accordance with EN 81, DAFA 74B:2018, SIA
370.001/A1 [2005], SIA 370.001/A2 [2006] or other
national regulations must be automatically recognized
before the start of every journey except for running-in
and readjustments. If an error exists, the journey is not
allowed to begin. The light curtain self test before every
journey ensures this.
SAFETY ADVICE
Under no circumstances may the output relays
(terminals WK, RK and AK) be connected
directly into the safety circuit of the elevator or
be connected with supply voltage (imperative to
also pay attention to Chapter 13).
12. Decommissioning, repair and
disposal

12.1 Decommissioning

cegard/Lift LI may only be removed from operation if
equivalent or better accident prevention means are put
into place e.g. a cabin door. For decommissioning, the
mounting kits, opto edges, control unit light curtain and
passenger instructions need to be removed.

12.2 Repair

Every repair is exclusively carried out by CEDES service
personnel or by technical service personnel approved by
CEDES in writing.
SAFETY ADVICE
Any other repairs can effect the safety and be
dangerous for the elevator users.
12.3 Disposal
Please recycle the packaging. Large quantities of packaging
can also be returned to CEDES subsidiaries.
CEDES subsidiaries or CEDES representatives accept
packaging and the disused device so that they can be
dismantled and the components can be reintroduced into
the material cycle.
