  If the Serai Gate Opener gearmotor is not working, check the motor power supply input terminals to see if they are live. Check F4 mains fuse efficiency. Check the 24V presence at the motor power supply clamps 5 and 6. Check that the power supply cable is not cut or broken (cable replacement must be carried out by an authorised technician). Also, check and replace the fuse if it's faulty.

  If the Serai Gate Opener gate is jammed against the mechanical end stop, remove the lower casing from the motor. Unscrew the nuts fastening the base plate bolts. Remove the motor from its position by releasing the pinion from the tooth rack. By hand, move the gate right away from the mechanical end stop. Release the motor manually. Reposition the motor on the base plate. Set the end stop sliding plates properly. Replace the lower casing and secure the motor. If necessary, repeat the work times and impact force setting programming.

Note that the impact control can be switched off by positioning the SW1 microswitch 1 to ON; in this case, other safety systems compliant with regulations in force (e.g. sensitive edges) must be adopted. If there was a power cut during operation, the first opening manoeuvre takes place during deceleration (if the gate is in an intermediate position) and can take up to 300 s; if it does not occur within this time, the gate must be moved to the fully open or fully closed position by hand. Also, check and adjust the position of the end stop slidin...
