F. SETTING GATE OPEN DIRECTION SWITCHES S2 AND S3

Figure 12. Gate Direction and UPS Low Battery Switch Locations.

NOTE: The Gate motion (left to right) is determined by looking at the gate from the gate operator side.

•Switch S2 sets gate opening direction (open to left or open to right). Sensed only on power up, it should be set when the power is off, or power should be cycled after setting the switch.

1.Set switch S2 to RIGHT for gate to open to right, or to LEFT for gate to open to left.

2.Set switch S3 to the direction you wish the gate to move (left or right) and remain when the LOW BATTERY input is activated by an Uninterruptable Power Supply (UPS).

G.POWER UP PROCEDURE

CAUTION

If gate is positioned at the ‘open’ limit, gate will automatically close if Relcose Timer is enabled and power is switched on. Position gate either at the closed limit or at no limit when preparing to switch power on. Always use extreme caution and follow all warnings in the Safety Summary.

1.Turn on 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.
