Initial Operation / Basic Setting - Chamberlain LiftMaster CB202 Instructions

INITIAL OPERATION / BASIC SETTING

Proceed step by step. When in doubt, start again at the beginning. Take sufficient time to make these settings.
1. Are all components required for operation connected? Motor, photocells, safety safety edge, stop switch.
2. Limit switches are fixed to the rack?
3. Setting of jumpers => all removed (settings can be done later on)
4. Make sure nobody is present in the gate area.
Note:
When connecting the control board for the first time (no basic setting has been done) the Diagnosis-LED will indicate
the status of the photocell terminals and, depending on the configuration, blink between 4 and 7 times. This indication
is regular and can be ignored until Basic Setting (also see page 12 "Diagnosis-LED").
Now connect control board to power
BASIC SETTING:
1. Move the gate manually to a position between the two
limit switches OPEN - CLOSE and lock drive.
2. Press buttons P1, P2 and P3 at the same time for about
2-3 sec. LED "LEARN" starts to flash.
3. Now watch the gate. The gate can be moved in both
directions using the button P1. Press the button P1 several
times (1-2 seconds each time) to understand the function of
the button. If none of the buttons are pressed for about 15
seconds, the control switches back to normal operation.
Repeat step 2 in this section.
4. Fully open the gate with the button P1.
Keep P1 pressed until the controller turns off by itself at
the limit switch OPEN. (Do not release beforehand).
Control: The LED "OPEN LIM" (yellow) = limit switch
OPEN should now light up and the gate can be opened
as required. Otherwise, change the limit switch position
before further settings are made.
5. Close the gate with the button P1 till it is turned off at the
limit switch CLOSED. (Do not release beforehand).
Control: The LED "CLOSE LIM" (yellow) = limit switch
CLOSED should now light up and the door can be closed
as desired.
Basic setting is completed.
