earlier.

Warning! The two magnets are fitted on the bracket in a position that enables their recognition by the ECU.

GEAR MOTOR RELEASE AND LOCK PROCEDURE
These two operations are required only in the event of a fault or power failure, and the user or assigned personnel must be
trainedbytheinstaller, whoshould provide a copyoftheseinstructionsto bekeptwith care togetherwiththereleasekey.
1) insert the key and turn clockwise 2) pull the lever through approx. 90° 3) the motor is released and the leaf can
bemovedmanually.To keepthe leafblocked,proceed asfollows.
3) close the lever 4) turn the safety key anti-clockwise; the gearmotor is then locked and the leaf can only be moved
electrically.
Before performing either of these procedures, ensure that the power supply is disconnected from the entire
automation,evenin theeventofa powerfailure.
