F. POWER UP PROCEDURECAUTION

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 warning 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.

G. USING MANUAL CONTROLSFigure 6. Manual Controls, Location and Use.

If necessary, use the manual controls on Manual Input Terminal TB2 (OPEN, CLOSE, and STOP, as shown in Figure 6), to move the gate arm during system installation.

•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 to the COMMON terminal.

IMPORTANT NOTE

If the STOP terminal is disconnected from the COMMON terminal, the gate is prevented from moving and no command will affect the gate.
