Motor Cable Positioning
Depending on the application, the motor cable can pass
through the center or side of the motor head. In the
LT50/60 versions simply raise the yellow cover plate
slightly, reposition the cable and then press the cover plate
into place.
Mounting the Motorized Tube
LS40 and LT50 RH
The motor brackets for the LS40 and LT50 RH are screwed
directly into the head of the motor as illustrated at left.
LT50/60
The motor brackets for the LT50/60 are equipped with a
spring ring. This spring ring must be used and does not
have to be removed for installation. You can press the
motor axially into the motor bracket in any of 6 positions,
so that the limit switch adjustment buttons are always
easily accessible. When the motor engages the motor
bracket, the spring ring makes a click sound. The spring
ring keeps the motor head securely seated in the bracket
for even torque distribution. For higher torque applications
a locking spring ring with screw must be used in place of
the standard spring ring.
Testing the Motor - Test Run 1

NOTE: It is important to note that SOMFY motors are
weatherproof, but NOT WATERPROOF and therefore the
motor head should not be exposed to direct rainfall.
Test Run 2
Allow the motor to run in both directions, until it shuts off in the
stop positions. Because of the built-in thermal protection
feature, the motor may shut off automatically after running
without interruption for an extended period of time. Please wait
until the motor has cooled off and is ready for operation again
(approximately 10-15 minutes).
Changing a Set Stop Position...
- Press the limit switch adjustment button that lies in the
direction of rotation.
- Bring the end product into the desired stop positon.
- Release the limit switch adjustment button by pressing it
down again.
Adjustment of Upper and Lower P ositions for the
LS40 Motor
- Connect the motor tester cable (Cat. No. 6020086) to the
motor cable, match the wire colors and connect to power.
- 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.
- 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.
- 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 off and turn the UP screw to "-". Repeat
this until correct setting is achieved.
NOTE: 7 T urns of Hex Screws equals 1 turn of roller tube.
- Flip the tester cable switch in DOWN direction. If the system
stops before its DOWN limit, turn the DOWN limit screw to
"+". If not, flip the tester cable switch off and turn the DOWN
limit screw to "-". Repeat this until correct setting is achieved.
NOTE: Recessed thumbscrews can accomodate a flat
head screwdriver, SOMFY’s Allen wrench or Flexible limit
switch adjuster.
