Motor wiring and limit
5. LIMIT SWITCH SETTING
SOMFY strongly recommends using a Tester Cable
(T.C.) Cat. No. 6020086 to set the motor limits, and to ensure the system
is operating correctly before the final electrical connection is made.
Refer to Step 6 "Trouble Sooting Guide" for any problems encountered.
Two positions have to be set" the UP & DOWN positions, this
is where the rolling shutter or awning will stop automatically.
- Ensure the tester cable switch is in the center
"OFF" position, and connect T.C. to motor leads by matching
- Remove the protective cap covering the limit setting
buttons on motor head, and replace when finished.
- Depress fully both limit switch push buttons. They
will automatically lock in the down position. Operate the T.C. switch
and check that the system operates correctly. Identify the UP limit
switch push button(refer to figure used for step 1). Press the T.C.
switch in the UP direction until the required position is reached.
Set the switch to the center "OFF" position.
- Unlock the UP limit switch push button by depressing
and releasing it.
- Repeat the above operation to set the lower limit.
Check with the switch that the motor stops at the up & down positions
- Always remember to affix the protective cap over
the limit switch buttons.
NOTE: Tubular motors are not continuously rated.
They have a built-in thermal overload device which limits their operation
to approximately 5 minutes.
6. WIRING/INSTALLATION RECOMMENDATIONS
All wiring must conform to NEC (National Electrical
Code) and local codes.
Do not wire two or more motors to one SPDT
(single pole double throw switch-NO PARALLEL WIRING).
Do not use light switches.
Do not wire two or more switches to one motor,
without using SOMFY's Multi-Switch Command (Cat. No. 6300427).
NOTE: SOMFY motors conform to IP44 requirements and
as such must be protected against direct weather elements such as rain,
SOMFY reserves the right to void the motor warranty if the wiring recommendations
are not followed.
**The motor cable should not act as a direct conduit
for the water to enter the head of the motor (form drip loops).
* Reverse the Brown and Red wire if the UP and DOWN
movement does not correspond to the UP and DOWN movement of the switch.
7. TROUBLESHOOTING GUIDE
SYSTEMS DOES NOT RESPOND
Is the power supply switched on? - check any
fuses in the system.
Is control switch wired correctly? Refer to
Are limit switches set properly? Review limit
The thermal protective device may have shut
the motor off.
Wait for cool down.
Check the wiring between the motor & the
Disconnect the switch & test the motor
with a tester cable.
THE SYSTEM IS NOT STOPPING
Is the limit switch crown wheel being driven by the tube (has
the tube profile been properly notched)?
Is the motor drive wheel securely fastened
to the tube?
NOTE: if the motor is tested outside the tube,
the crown wheel has to be manually turned in order to stop the rotation
of the output shaft.
