Motor Adjustment Instructions 50 Series Motor
Limit Settings and Torque Settings
General
Important Information
These motors are equipped with
permanent overheating protection. When the motor
"runs hot", followed by a cooling down
phase, the motor will only switch on again if the
operation switch has been switched to the neutral
position for at least 20 seconds and the motor is
sufficiently cooled. |
Important
Information
The position of the Studio Star shutter axle
determines the shut-off in either direction via the
crown. If the motor is not installed inside the axle,
the crown does not move and the shut-off devices inside
the motor do not function. These adjustment instructions
picture an outside left motorized Studio Star; however,
the same information applies to an outside right
motorized shutter only the direction of adjustment for
the buttons is reversed. A rule of thumb to remember
when adjusting a Studio Star shutter is that the limit
switch closest to you (the front of the housing) is the
up adjustment; the switch towards the back of the
housing is the down adjustment.

Adjusting
the endpoints
Lower shut off point:
Press in the adjusting switch all the way for
the axle direction "down" and let it go
when the lower position is reached.
If
the motor runs further than desired at the lower
position, return the Studio Star to the desired
position and switch off your test cable. Push in
the adjusting switch all the way for the axle
direction "down" and check the lower
position.
Upper
shut-off point:
Switch your test cable into the "up"
position and press in the adjusting switch all the
way on the motor for the axle direction
"Up" and maintain the switch. This will
allow the Studio Star Shutter to go up. ! Note: If
the housing cover is off, ensure that the curtain
is received by the guiderails correctly.
By
switching off at the test cable , stop the shutter
at the desired position. (You can also tap the
"up" on your test cable to get the
desired position).When the motor is switched off,
press in the adjusting switch once more all the
way for the axle direction "up".
Move
the shutter approx. 2 feet down and then up again
in order to check the set position. If you missed
the correct position in the "up"
direction, let the shutter go to the correct
position and press in the adjustment switch for
the axle direction "Up". Now the exact
position is set. |
The
limit switch adjustment can also be done in the opposite
sequence, because the upper and lower positions are
independent from each other.
Important
for Re-adjustment!!
ONLY press the switch of the axle rotational
direction that is to be corrected! If the other switch
is also pressed, then this point must also be
re-adjusted!
Studio
Star Motor Adjustment - Torque Settings for 50 Motors
All
Studio Star shutters are pre-adjusted from the factory
by a technician. Under proper operation, the shutter
motor should switch off in the up-direction set position
or if the shutter is blocked by on obstruction. In the
down direction, the motor switches off in the down set
position or will spin freely if obstructed. If it is
necessary to change the torque settings, please note the
placement of the torque screws and adjustment switches.

Torque
Adjustment
First,
run the Studio Star shutter up until it stops.
Assuming that it does not go up all the way, keep
the test switch in the up direction and maintain
the "up" limit switch on the motor. The
motor should now continue to move the shutter up.
If possible, set the position for the
"up" direction using the limit switch.
At
this point, if the shutter still will not move all
the way up, you will need to adjust the torque
settings. |
While
maintaining the "up" direction on the test
switch, hold in the limit switch in the direction of
adjustment and turn the torque screw clockwise (use a
3mm allen wrench). Make sure that you are turning the
torque screw corresponding to the direction of
adjustment. When the shutter is at the proper height,
release the limit switch to set its position. After you
have satisfactorily set the "up" limit, run
the shutter down several inches using the test switch
and then back up to ensure that is has set. At this
point, you have already set the limit switch - do not
change that. Check that the curtain will stop moving if
obstructed by holding the top of the curtain while it
runs up.
| NOTE:
Both the limit switch and toque settings are
capable of stopping the shutter in the
"up" position. It is very important that
the LIMIT switch stops the motor from running and
NOT the TORQUE setting. If the torque setting
stops the curtain at it's top position and NOT the
limit switch, the shutter can be seriously
damaged. |
In
the down direction, the torque adjustment is
pre-adjusted from the factory also. In the case of an
obstruction in the "down" direction, the motor
will not shut off but the shutter will go into a
"free spin". However, in the case of a shutter
that makes excessive noise while going down, it is
possible that the torque switch should be adjusted. Turn
the appropriate torque screw clock-wise until the
"clicking" noise stops.
