Unauthorised manual operation is restricted by providing a cover (15) alongwith a padlock
arrangement on the door. For manual operation first the front door to be opened after removing the
padlock and then cover (15) can be removed for insertion of the manual handle. Ensure blocking
magnet (19) (if provided) is energised or pulled up manually. For safety ensure Local-Remote selector
switch is in Local mode.
2.2
Blocking Magnet
Optionally a blocking magnet (19) can be installed. The blocking magnet de-energised prevents the
motor-operated mechanism from being operated manually. In this case it is not possible to insert the
hand crank (18) into the auxiliary pin (8) for emergency operation. In the case of AC operation, a
rectifier (37) is installed upstream of the blocking magnet. An additionally interlock switch (51), directly
attached and actuated by the blocking magnet (19) allows electrical operation only when the blocking
magnet is energised.
