MOUNTING INSTRUCTIONS FOR 3T-MOTORS MINI-TUBE RADIO MOTORS
MOTOR TYPE 3T35-R
Use proper suspension springs:
•
To fasten the roller shutter curtain to the roller shutter shaft, please be sure to use
suitable suspension springs for motor operation. These special mini suspension springs only protrude
approx. 1 mm into the shaft. This allows the shaft to rotate freely. When commercially
springs are used, there will be grinding marks on the motor housing because the suspension pin
protudes too far into the roller shutter shaft, which leads to damage and destruction of the motor.
In case of any kind of grinding marks on the motor housing, the warranty claim is void.
•
Matching mini suspension springs can be found in our store under mounting accessories.
Use correct roller shutter shaft with external fold:
•
For steel shafts with a width across flats of 40 mm (SW40), only use shafts with
an external fold. Steel shafts with an internal fold will damage and destroy the motor.
Explanation:
•
Avoid overstressing and resulting premature aging of the motor by using the correct suspension springs and the correct roller shutter shaft with external fold!
•
Keep in mind that the motor housing has a diameter of 35 mm and the roller shutter shaft SW40 has an outer diameter of 40 mm. When using commercially
available springs or roller shutter shafts with internal fold, the motor housing will be left with grinding marks, since the suspension pin or the fold protrude too far
into the roller shutter shaft. Contrary to its intended use, the motor runs permanently against an overload and outside its characteristic data.

Suspension spring
•
If the shaft has to be turned a little to hook in the suspension springs, use the adjustment pin on the
limit switch screw for the lower end position in the PLUS direction. This causes the motor to turn the shaft
stepwise. The rectangular openings in the shaft for hooking in the suspension springs should point forward
and be easily accessible.
•
Hang the roller shutter curtain on the roller shutter shaft using the suspension springs.
2. Setting the upper end position
•
Allow the motor + roller shutter to move upwards until the motor stops automatically at the previously set upper end position.
•
To set the upper end position, turn the adjustment pin on the limit switch screw for the upper end position in the PLUS direction
to raise the motor + roller shutter further. The upper end position should be that the roller shutter stops approx. 3 cm before
the roller shutter box. Reason is the expansion of the roller shutter due to the temperature difference in summer and winter.
•
After setting the end positions, lower and raise the motor + shutter to check the set end positions.
