Motor shuts off. Motor has been in use for more than two minutes
Motor is designed for short operations (lowering and retracting), continuous duty. Longer operation causes the motor to overheat and shutoff. This typically happens during installation when testing the screen.
Allow the motor to cool down. Complete cooling can take an hour or more. Heat gain is cumulative and takes time to dissipate. If the motor use is initiated before it has cooled completely, the motor will shut down again when it reaches maximum temperature.
