WARNING
Non-compliance with the checking and adjustment requirements for the safety reverse system can result in a
closing door causing serious, life-threatening injuries. An appropriate test should be carried out and repeated on a
monthly basis. If necessary, the sensors need to be readjusted.
INSTALLATION - GARAGE DOORS
The CB3 control unit permits the connection of two pairs of light barriers (opening & closing). In such cases, one pair of
sensors can be installed at the sides of the door on both the inside and outside (fig. 3). However, the sensors must be
mounted and connected in such a way that the transmitter and receiver lens are located exactly opposite each other as
shown in (fig. 3). The sensors must be mounted securely to a solid surface, such as the posts or wall on both sides of the
door. The invisible beam of light may not be interrupted. No part of the garage door (e.g. door rails, springs, hinges, rollers,
other hardware, etc.) may interrupt the beam during the closing process. If this is not possible, an upright column element
(accessory) has to be ordered. For the protection of infants and small children, the safety light barrier should not be
installed higher than 150mm-200mm above the garage floor.
INSTALLATION - SWINGING DOORS - SLIDING DOORS
The control units permit the connection of several pairs of light barriers. The sensors must be mounted securely to a solid
surface and be located exactly opposite each other. Very important to note in this connection is that the slope or inclination
of entrances be given due consideration. Cable lengths in excess of 10m should be avoided. Light from a low sun or exces-
sively thin cable can seriously restrict the range available. If two pairs of light barriers are mounted closely together (sliding
door), the receiver/transmitter may not be located on the same side of the entrance as otherwise one transmitter lens would
influence the two receiver lens. For the protection of infants and small children, the safety light barrier should not be
installed higher than 200mm-250mm above the garage floor.
ASSEMBLY/MOUNTING
The power supply must be disconnected prior to assembling/mounting the safety light barrier.
1. Open housing as shown in fig. 1.
2. Align sensor such that the lens are located laterally to the door and point exactly at each other.
3. Fasten sensors in place with screws / plugs.
4. Inside the garage, use insulated staples to fasten the cable to the wall and ceiling. Outdoors, only use cable approved for
such applications and, if necessary, run it through an empty tube. High voltage and low voltage may not be run together
through one cable as this may disrupt the sensors. Ensure that the sensors are sufficiently watertight and that the rubber
gasket is used for cable connections.
5. Connect the cable (min. 2 x 0.25mm²) to the terminals as shown depending on the given control unit (figs a-g).
a. Garage door openers: Select the model of your choice from the figs (a-b). The cable from the plus terminal on the
sensor should be connected to terminal 3 (black). The other one should be connected to terminal 2 (white).
b. Openers for swinging doors and sliding doors: Select the model of your choice from the figs (c-f) and connect the cable
as shown. Connect plus/plus - minus/minus
6. Connect power supply to opener.
a. The two indicators, both in the transmitter lens and the receiver lens should light up if the terminal connections and
alignment are correct.
b. Should the light indicators flash (if the invisible light beam is blocked), the sensors need to be aligned. Loosen the
receiver lens housing such that the sensor can be moved slightly. Adjust the sensor vertically and/or horizontally until the
red indicator lights up and stops flashing. Washers or the like may have to be fitted.
7. CHECKING THE SAFETY LIGHT BARRIER
• Press the key on the remote control or the switch for opening the door.
• Place a sufficiently large obstacle under the door (see fig. 2 as an example) such that the sensor beam in the doorway
is interrupted.
• Press the key on the remote control or the switch for closing the door. The garage door opener/door does not close
when activated via the remote control if the light indicator in one of the sensors is flashing (which means that the sensor
is incorrectly aligned or blocked by anobstacle).
Consult a specialist in cases where the opener closes the door despite its path being blocked by an obstacle.
Our electrical and electronic equipment may not be disposed of with household waste and must be disposed of
after use properly in accordance with WEEE Directive EU: 2012/19/EU; GB UK(NI): SI 2012 nr. 19 on waste elect-
rical and electronic equipment in order to ensure that materials are recycled. Collecting waste electrical equipment
separately means environmentally-friendly disposal and is completely free of charge for the consumer.
WEEE reg. no. in Germany: DE66256568.
Any waste packaging left over with the end consumer must be collected separately from mixed waste, in accordance with
the Directive. Packaging may not be disposed of with household waste, organic waste or in nature. Packaging material
must be separated according to its material and disposed of in the recycling containers provided and in certain council
recycling bins.
!
You must ensure that the signal from the light barrier recognises the presence of persons or objects (vehicle).
Without additional safety precautions, the sensors do not guarantee total safety.
