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
transmitter, a commercial three-channel radio receiver
(with connections for OPEN/CLOSE/STOP) is
recommended.
2. Be sure to run all control wires through the conduit hole
in the electrical box enclosure marked with the label
shown below.
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.
