PHOTOCELLS (OPTIONAL) MODEL: 771E, 772E
The photocells are for safeguarding the gate and must be used. The fi tting location
depends on the gate's design. EN12453 specifi es that a pair of photocells must be in-
stalled at a height of 200 mm and activated to "Close". The photocells consist of a trans-
mitter and a receiver and must be opposite each other. The photocell is mounted on
the wall using small screws and wall plugs. To enable the "Automatic Closing" function,
the Chamberlain failsafe photocell must be installed. The Chamberlain failsafe system
(2-cable system) has small LEDs (light) that can be seen from the outside on both sides
to indicate the status of the photocell.
Programming of IR sensors:
- connect IR sensors
- program the travel of the gate.
Deletion of IR sensors:
Disconnecting already connected IR sensors will cause the control board to
block the functionality of the terminals it was connected to.
To delete IR sensors correctly:
- disconnect IR sensors
- cut control board from current shortly
- program the travel of the gate.
Diagnosis of the photocell
LED constant = OK
LED fl ashes = photocell disables control board
LED off = no current, incorrect connection or polarity
Diagnosis on the control board
LED off = OK no photocell connected
LED fl ashes = photocell disables control board
Connection between 1 & COM:
Active when gate is closing (reverses gate to open)
Connection between 2 & COM:
Active when gate is closing and opening
Connection between 3 & COM:
Active when gate is opening (holds gate in present position until photocell
is cleared; continues when cleared)

RADIO AND RADIO PROGRAMMING

PROGRAM / DELETE REMOTE CONTROLS
The receiver has two channels CH1 and CH2. Using the different channels
enables the opening of one wing resp. both wings. For example, if CH2=P2
receives the code from the remote control only one wing will open. Choosing
a different button on the remote control in combination with CH1=P1 will
cause both wings to open.
PROGRAMMING
1. Switch on DIP "RADIO"
2. Briefl y push button P1 (for CH1) or P2 (for CH2) and the
respective LED lights up.
3. Press and hold a selected button on your remote control until
LED goes out after 5 times fl ashing. Done!
Repeat for all remote controls (a maximum of 85 remote
controls can be programmed to each channel).
Important: To fi nish programming, Switch off DIP "RADIO"!
Note: Make sure not to program the same remote control button to
CH1 and CH2, otherwise the gate will work improperly.
DELETE
- Switch on DIP "RADIO".
- Press and hold learn-button P1 for approx. 10 seconds
until LED goes out again. All codes programmed are deleted.
To confi rm both LEDs CH1 and CH2 fl ash 8 times.
- Switch off DIP "RADIO".
