Danger warning

Warning
The light curtain should never be installed in the
elevator control in a manner which allows the doors
to be opened during an emergency stop caused by
an interruption of the protective field in the unlock-
ing zone. This results in a dangerous step. Please
read the instructions in section 3.2.7.
If a person leaves the elevator car at this holding
position without pressing the desired landing floor
button again, with hydraulically driven elevators,
there is still the danger that the elevator can slowly
fall away from the holding position due to leakage of
the elevator's hydraulic system. The next elevator
user could fall into the cabin or the elevator shaft
after the landing doors are opened.
This risk does not arise if the cegard/Lift is con-
nected correctly.
Please check your installation in accordance with
the specified criteria in section 9.

Application

The cegard/Lift light curtain serves to protect people
in cargo and passenger elevators without elevator
cage closure doors. The speed at which the elevator
cage travels should not exceed 0.85 m/s (max. 0.63
m/s in Switzerland). All valid national regulations
should be observed.
Important notices:
cegard/Lift is constructed exclusively for elevators,
and should not be used in areas where there is a
risk of explosion (EX-areas).
cegard/Lift carries out a self-test:
Before each journey,
Every time a person or object
interrupts the light curtain.
Every malfunction involving the opto edges, system
control rack or incorrect wiring leads to a shutdown
of the elevator system.
If an object causes an emergency stop by penetrat-
ing the protective field during the journey, it can be
signalled either audibly or visually.
A journey interrupted by the safety equipment can
only be continued after the protective zone is re-
enabled by a new drive / journey command from the
interior of the elevator cage.
Both entrances are simultaneously bridged in the
case of a through-loading elevator. This occurs re-
gardless of whether there are one or two entrances
to the elevator cabin on a floor.
cegard/Lift offers the following advantages:
Also ideal for controlling automatic doors
thanks to an additional output
Cost effective
Simple integration in practically all existing
elevator control systems without additional
suspended cables
Simple, space-saving installation
No setting or optical adjustment necessary
Short installation time, can be easily carried
out by just one single person
Inexpensive alternative to elevator cage clo-
sure doors
Monitoring of up to two elevator cabin en-
trances
Large range and dense protective field
Automatic start after power-up
8 isolated inputs for cabin call signals,
12 ... 265 VAC / DC
