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.
9.1.
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.
9.2.
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.
9.3.
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).
9.4.
Reflectivity
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 (4.3), using a matt
black paint, by sandblasting or by applying a lens
aperture or by increasing the distance to the shaft
wall.
9.5.
Cleaning of opto edges
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.
9.6.
Protective circuit
The safety circuit of cegard/Lift LI must fulfill the
following requirements:
R
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).
R
The system must be bypassed for running-in and
readjustment purposes.
R
Stored journey commands do not need to be
deleted at a reaction of the safety device.
R
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.
R
An impairment of the safety directive by a
failure in accordance with TRA 262.12, SIA
370/10 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.
Important safety information:
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 11).
