C. RUNNING INPUT WIRING
1.
Remove the plastic control box cover.
2.
Run wires from input components and Master/Slave conduits into control box.
3.
For Master/Slave wiring, refer to Installation and Operation of the SL 1000, SW 2000, BG 3000, and
BG 3100-X1 Master/Slave Configurations, document number 6001376.
Route but do not connect input wires at this time. If inputs are connected now, the gate operator may
activate at random during installation, potentially injuring installation personnel.
D. SETTING GATE OPEN DIRECTION SWITCHES S1 AND S2
1.
Gate opening direction is set by switch S1, located on the control board. The switch is sensed only
on power up, so it should be set when the power is off.
2.
Ensuring power is off, set switch S1 to the left if the cabinet access door faces away from the
driveway (typical installation), or to the right if the access door faces the driveway (restricted
installation).
If the system was ordered with the Power Fail Operation option:
3.
The power failure gate opening direction is set by switch S2, located next to switch S1 on the
control board. Set switch S2 to the left to fully open (Fail Safe) or to the right to fully close (Fail
Secure) the gate during power outage (typical installation).
E. POWER UP PROCEDURE
1.
Turn on the circuit breaker that provides power to gate operator.
2.
Turn on gate operator power switch and verify that the seven-segment LED display above the
keypad sequentially spells out "HELLO". The only LEDs that should remain on are MAGLOCK and
CLOSE LIMIT or OPEN LIMIT, if one of the limit switches is 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.
