Explanation of the limit switch screws
There are 2 limit switch screws on the motor head. One limit switch screw is responsible for the upper end position, the other for the lower end position.
The end positions can be adjusted by turning the limit switch screws with the adjustment pin.
The arrows with PLUS and MINUS apply to both limit switch screws and show you in which direction you must turn the adjusting pin to switch
off the motor sooner or later. Turning the limit switch screw in the PLUS direction after switching off allows the motor to continue moving step
by step in the corresponding direction. Turning the limit switch screw in the MINUS direction during travel causes the motor to switch off earlier.
For motor type 3T45/12V / power cable to the front, the PLUS and MINUS directions change (see marking on the motor head).
Motor type 3T45/12V / Power cable to rear
Motor type 3T35/12V / Power cable to rear
Motor type 3T45/12V / Power cable to front
The straight up and down arrows indicate the direction of rotation
of the motor and shaft and thus show you for which end position
the limit switch screw next to it is responsible. Depending on
whether the direction of rotation leads to unrolling or rolling up of
the roller shutter, the limit switch screw is responsible for the lower
or upper end position (unrolling > lower end position, rolling up >
upper end position).
Adjustment pin
On motor type 3T35/12V, the limit
switch screws are located on one
side of the motor head only.
