2. Mount the emitter and the receiver
The emitter and the receiver edge can be mounted
either to the door wings, to the door wing and the
slam post, or to a frame that is attached to the car.
The black "eyes" in the aluminum profile are the
optical elements which is the front of the edge. This
side has to "look" at its companion piece, which is
mounted on the opposite side of the cab door or slam
post.
Please note that the receiver (the one with the blue
connector) can be sensitive to "foreign" light. No
other source of external light, including the emitter of
any other light barrier system, should be directed
towards the receiver edge. Although cegard/Mini is
very tolerant of bright sunlight, it is better to mount
the receiver edge so that no sunlight shines directly
into the receiver lens. It is similar to human eyesight:
while you may have visibility even if looking directly
into the sun, it is harder to see clearly. Therefore, it is
always better to have the sun at your back!
Please note that objects smaller than the sensor
spacing may not be detected! In the USA and
Canada or for dynamic
recommended to use cegard/Mini with 32 elements.
Please observe
guidelines:
1. Never scratch or paint the optical lenses be-
cause they form the light path! Do not drill addi-
tional holes into the profile. Unpack them just
before installation in order to avoid damage!
2. Do not bend or twist the edges!
3. Oil may damage the cable. Contamination must
therefore be avoided at all times!
4. Avoid external light from other infrared light
sources like photo eyes, light barriers or direct
sunlight!

Installation and Operation Manual
5. For installation of opto edges please note:
• Exit both cables, emitter and receiver, the
same direction
• Do not bend the cables or expose them to
tension
• Ensure cables are kept as far as possible
away from AC mains or high voltages
• Do not force, stretch or squeeze the cables
• Ensure that the cable is well fastened and
routed
• Avoid soiling of opto edges
• Avoid contamination by oil or greasy liquids
• Avoid obstruction from door wings, cables
etc. in the protective area
3. Guide the cables properly to prevent
damage
Guide the
mounting material, e.g. cable protection tubes,
neoprene cable ties, cable guide wires (depending
on the type of mounting kit used).
If the cables are not properly fixed and guided,
their lifetime could be reduced drastically. They can
also be damaged due to possible swing and snag in
it is
the hoistway! Always follow the cable guide
instructions carefully, which can be found in the
appropriate mounting kit installation and operation
manual.
4. Connect the emitter and the receiver
cables
Make sure that the power supply voltage available for
cegardMini is between 14 and 30 Volts DC. The
power supply has to provide at least 100 mA for
proper operation.
cegard/Mini meets all standards for resistance to
electromagnetic interference (EMI). However, it is
prudent to guard against interference.
Therefore, do not guide cegard/Mini connection
cables close to cables carrying high voltage and/or
high current. The cegard/Mini cables should also be
mounted as far away as possible from the door drive
motor or motor inverter (VVVF-drives) to avoid EMI
problems.
