E. POWER UP PROCEDURE
1. Turn on circuit breaker that provides power to gate operator.
2. On Manual Input Terminal TB2, connect the STOP terminal to the COMMON terminal (see
Figure 13).
3. Turn on gate operator power switch and verify that the row of LEDs on the right side of the
controller board all turn on, then turn off sequentially, starting from the bottom. The only LEDs
that should remain on are Power ON, MAGLOCK, and CLOSE LIMIT or OPEN LIMIT, if one of
the limit switches are engaged.
NOTE:
If the LEDs do not follow this pattern, the controller board may not be working
correctly. Stop installation and call LiftMaster Technical Support for assistance.
On Manual Input Terminal TB2, disconnect the STOP terminal from the COMMON terminal.

F. USING MANUAL CONTROLS
Use the manual controls on Manual Input Terminal TB2 (OPEN, CLOSE, and STOP, as shown in
Figure 13), to move the gate for limit cam adjustments.
•
To open the gate: connect the OPEN and STOP terminals to the COMMON terminal.
•
To close the gate: connect the CLOSE and STOP terminals to the COMMON terminal.
•
To stop the gate: disconnect the STOP terminal from the COMMON terminal.
If the STOP terminal is disconnected from the COMMON terminal, the gate is prevented
from moving and no command will affect the gate.
