TROUBLESHOOTING
WHAT TO DO WHEN ...
... the motor does not run?
•
Mains voltage is missing.
•
Check correct connection of the control (switch or timer).
... the motor is running in the wrong direction?
•
Swap the two wires for the direction of rotation (brown + black).
... the motor does not switch off at the set point?
•
Check fit of limit switch adapter (must be flush with motor head and shutter shaft).
•
Roller capsule is not fixed or roller shutter shaft is too short.
•
Set limit switch screw correctly (see instructions):
MINUS turning during travel shortens the travel distance; PLUS turning after switch-off extends the travel distance.
... the motor does not switch off at all?
•
Engine was run in removed state (limit switches only work in installed state).
•
Check fit of limit switch adapter (must be flush with motor head and shutter shaft).
•
Limit switches are too far apart:
•
Determine limit switch screws according to explanation on page 11.
•
Do not fasten roller shutter armor!
•
Only allow the shutter shaft to be rotated by the motor.
•
While driving, turn the relevant limit switch screw in the MINUS direction (up to 100 turns depending on the motor type) until the motor switches off.
•
Then allow the roller shutter shaft to rotate in the opposite direction and turn the other limit switch screw in the MINUS direction until the motor switches off.
•
Repeat the entire process (Drive up turn MINUS / Drive down turn MINUS) until the motor switches off in both directions after 2 - 3 rotations.
•
Then allow the roller shutter shaft to rotate downwards until the limit switch is switched off. After switching off, if necessary, continue to move the motor by
turning the relevant limit switch screw PLUS to position the holes for the suspension springs.
... the motor stops running after continuous operation?
•
The thermal protection switch of the motor has tripped. After a cooling phase (min. 10 min.), the motor is ready for operation again.
... the motor turns in only one direction?
•
Check correct connection of the control (switch or timer).
•
Check the setting of the limit switches.
... the motor does not operate at the specified speed?
•
Check roller shutter weight; if necessary, correct inclined installation of roller shutter shaft or Eliminate mechanical friction in the roller shutter box or rail guide.
