18 - SETTING THE LIMIT SWITCHES
When first powered on, the board will scan for any BlueBus photo eyes connected. If at least one eye is not detected, then one
of the auxiliary inputs must be programmed to either pulse open or pulse close, with an External Entrapment sensor connected
before learn mode is initiated.
NOTE: The control board is already in the "LEARN MODE" when shipped. You are in LEARN MODE if the word "ENTER"
is flashing below "LEARN".
If the board is not in "LEARN MODE", press:
FUNCTION  OK  SWING  OK  LIGHT  OK
You are in LEARN MODE if "ENTER" is flashing.
For dual gate installations - set one motor at a time.
