Operation: When the infrared beam is interrupted during the closing process,
the door stops and reverses completely. When the infrared beam is interrupted
during the opening process, the door stops. Any subsequent functions are
dependent on the type of controller used for the swing or sliding door.
Attention:
- Installations on slopes or slanted driveways require very precise work.
- Avoid cable lengths of more than 10 m.
- Low angle sunshine or under-sized cables can greatly reduce the range.
- If 2 photocells are installed close to each other with little distance between them
(e.g. for sliding doors), the receiver and transmitter should not be mounted on
the same side of the entrance, or else one transmitter (TX) can influence both
receiver lenses.

ASSEMBLY
Before installing the photocell, the power supply must be shut down.
1. Press in the latch with a suitable screwdriver and open the housing (Fig. 1).
This snap mechanism enables quick installation. Keep the housing open during
the installation so that the diagnosis of the LED can be seen.
2. Mount and align transmitter and receiver accordingly. Use at least 2 screws for
attaching the transmitter and receiver, and ensure that the cable routing is exe-
cuted properly (Fig. 6). Align the sensors in such a way that the lenses precise-
ly face each other parallel to the door. There is a bracket for the lens inside the
772E, which enables an optional alignment (Fig. 3b). After alignment, tighten
the two screws (8) (Fig. 7).
3. The connection cable must be laid in accordance with local building and electri-
cal regulations. High and low voltage lines are not to be laid together in a single
cable; it leads to malfunction.
4. Connect the cable (min. 2 x 0.5 mm2) to the terminals according to the
controller.
a. Garage door opener: Selection of the model based on the images (a-f).
The connection is done according to the wiring diagram.
b. Swing and sliding door operators: Selection of the model based on the
images (g-m). The connection is done according to the wiring diagram.
5. After connecting the photocells, operate the drive.
a. LED on both transmitter and receiver lights up, if the connection and
alignment were executed properly.
b. LED flashes on transmitter and receiver, if the infrared beam is interrupted,
or if the alignment is not correct. Remove obstruction or re-align until the
LEDs stop flashing.
6. Close the housing of the photocell.
