Adjustment of Upper and Lower Positions for the LS40
1
Ensure the tester cable switch is in the center "OFF" position,
and connect T.C. to motor leads by matching color codes.
2
Identify the UP recessed limit screw by finding the arrow on
the motor head which points in the direction that retracts (rolls
up) the system.
3
Turn the power on to ensure that the switch is operating
properly (UP-raises, DOWN-lowers). If not, turn the power off
and simply reverse the black and red motor leads.
4
Flip the tester cable switch in the UP direction. If the system
stops before its UP limit, turn the UP screw to " " until
necessary. If the system does not stop at its UP limit, flip the
tester cable switch in the DOWN direction and turn the UP
-
screw to " ". Repeat this until the correct setting is achieved.
NOTE: 7 turns of Hex Screws equals 1 turn of roller tube.
5
Flip the tester cable switch in the DOWN direction. If the
system stops before its DOWN limit, turn the DOWN limit
+
screw to " ". If not, flip the tester cable switch in the UP
direction and turn the DOWN limit screw to " ". Repeat this until
the correct setting is achieved.

NOTE: Tubular motors are not continuously rated. They
have a built-in thermal overload device which limits their
operation to approximately 5 minutes. A maximum 15
minute cool down period is required if the motor reaches
thermal overload.
