The extremely compact rotary drive generates the rotating movement
for the opening and closing of the door panel. Also available
is a rotary drive which lifts the door when it is closed. Using
this lifting movement in the closing phase, the door panel goes
automatically to the "blocked" position using four wedges
so guaranteeing a perfect and safe closure of the door panel under
all conditions.
Electric rotary drives may be supplied to operate at 12 V or at
24 V.
All rotary drives have an emergency mechanical ignition control
in case of electricity blackout.
Door kits
can be supplied with two different types of rotary drives :
-
Ref.
8422.01.D/S rotary drives (12 V) or ref. 8479.01.D/S rotary
drives (24 V) only generate a rotation movement, opening-closing
the door.
-
Ref.
8423.00.D/S rotary drives (12 V) ref. 8480.00.D/S rotary drives
(24 V), as well as the rotation movement opening-closing the
door, also lift the door itself.
Type A and B motor control door rotation by means of an electronic
card that receives door opening-closing signals through micro-switches
mounted on the motor.
