3. Apply power to the operator. Press OPEN push button and
observe direction of door travel and then Press the STOP
button.
If door did not move in the correct direction, check for improper
wiring at the control station or between operator and control
station. NOTE: In "Diag" mode the 3-button control station can be
tested to verify correct wiring of Open, Close and Stop buttons
without moving the door.
If the door moves in the wrong direction and or the limits move
in the wrong direction, turn dial to programming mode. Remove
the Motor Direction Jumper. Press and release the MRT button to
set the jumper to switch the motor direction and the limits
(Default). Or press and release the MID button to set the jumper
to switch the motor ONLY. Reinstall the Motor Direction Jumper
to save the settings. In run mode, use the jumper to change
direction as programmed above.

MOUNTING INSTRUCTIONS

1. Mount Control Stations no further than (12") from each other.
2. Mount Control Stations (12") from the door enclosure.
3. Mount WARNING NOTICE beside or below the Control Station.
4. Mount MAINTENANCE ALERT label to either side of control
station.

EXTERNAL RADIO WIRING CONNECTIONS

On all models with B2 control wiring, a terminal bracket marked
R1 R2 R3 is located on the outside of the electrical enclosure.
Any commercial type LiftMaster brand receiver may be mounted
to this bracket. The operator will then open a fully closed door,
close a fully open door, stop an opening door, and reverse a
closing door from the radio transmitter. In TS control wiring the
operator will only open the door or reset the timer to close.
However, for additional door control from a 3-button remote, a
commercial three-channel radio receiver (with connections for
OPEN/CLOSE/STOP) is recommended.
