On all models with B2 control wiring, a terminal bracket
marked R1 R2 R3 is located on the outside of the electri-
cal 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 oper-
ator 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 recom-
mended.
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.
