Radio And Radio Programming - Chamberlain LiftMaster CB202EV Instructions

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 installed outside at a
height of 200 mm and activated to "Close". The photocells consist of
a transmitter and a receiver and must be opposite each other. The
photocell is mounted on the wall using small screws and wall plugs.
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:
- switch off control board
- disconnect IR sensors
- switch on control board
- program travel distance
Diagnosis of the photocell
LED on = OK
LED fl ashes = photocell disables control board
LED off = no current, incorrect connection or polarity
Diagnosis on the control board LED PHO1 / PHO2
LED constant = OK
LED off = A (no photocell connected)
B (photocell interrupted and diagnostic LED is fl ashing.
See page 13)
Connection between 1 & COM:
Active when gate is closing (reverses gate to open)
Connection between 2 & COM:
adjustable:
DIP "PHO 2 MODE" is off >> active when gate is closing
DIP "PHO 2 MODE" is on >> active when gate is opening

RADIO AND RADIO PROGRAMMING

PROGRAM / DELETE REMOTE CONTROLS
The receiver has two channels CH1 and CH2.
The respective LEDs CH1 and CH2 are assigned to these two
channels. Receiving a signal from a programmed remote control
button, CH1 fully opens the gate.
Receiving a signal from another programmed remote control
button, CH2 partially opens the gate (pedestrian mode).
PROGRAMMING
1. Switch on DIP "RADIO PROGRAM"
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 PROGRAM"!
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 PROGRAM".
- 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 PROGRAM".
