MANUAL RELEASE (fig. 12-13)
The self-locking automation is fitted with a manual release mechanism that
allows you to move the garage door manually during blackouts.
To release the motor (for both the master and slave units) move the lever "A"
(fig. 12) that is built into the carter.
The lever is connected to a special transmission transfer mechanism (force
multiplier) which makes the manoeuvre fluid and easy to operate.
- Lever horizontal "A" (fig. 12), automatic operation (gears active).
- Lever vertical "B" (fig. 13), manual operation (gears released).
MOUNTING THE TRANSMISSION COMPONENTS (fig. 14-17)
The transmission transfer mechanism connected to the lever allows the motor
to be released from a remote position (without using the lever on the motor).
The second activation point is located on the base of the frame (both to the left
and to the right of the motor body) and this permits the use of different manual
release systems:
1) Using an 8 mm hexagonal key, operating from outside the garage, you pass
the key through a hole drilled into the garage door panel (fig. 14).
2) Using a steel manual release cord (with sheath) attached to the door handle
(optional kit, see paragraph "Manual release cord").
Note: The two-sided release activation mechanism allows garage door manu-
facturers to build the release transmission mechanism into the door itself using
rigid bars.
Operations to carry out before installing the motor on the door panel.
To use the remote transmission mechanism (for the different systems) you must
first install the alloy transmission component "C" fig. 14 supplied with the kit.
• According to the characteristics of the system work out the best position for
the transmission component "dx" right or "Sx" left.
• Remove the protective carter "d" fig. 14.
• Insert the alloy component "E" fig. 15 in the chosen position and fasten it to
the rotating pin "F" fig. 16 (internal hexagon) using the supplied self-tapping
screw, then tighten down "G" fig. 17.
• Make sure the component is correctly fitted and rotates freely by rotating the
manual manoeuvring lever integrated into the motor's carter.
OPTIONAL MANUAL RELEASE CORd (fig. 18-25)
Mounting the manual release cord
• According to the characteristics of the system work out the best position for
the manual release cord dx right or Sx left.
• Remove the protective carter "H" fig. 19.
• Insert the plastic travel limit component "I" fig. 19 into its seat and fasten
down using the supplied self-tapping screw "L" fig. 20.
Note: The travel limit component is indispensable if you need to relock the
door externally using a door handle attached to a manual release cord.
Once the travel limit component has been inserted the manual release lever
integrated into the motor's carter can only rotate partially (about 45°).
• Insert the sheath holding cylinder "N" into its seat on the alloy transmis-
sion component "M" fig. 21.
• Insert the round head of the cable "O" fig. 21 into its relative seat.
• Pass the cable through the eye hole on the sheath holding cylinder "P"
fig. 22.
• Slide the ferrule "Q" fig. 23 on to the steel cable.
Note: The use of the ferrules is fundamental for the correct working order
of the cord operated release system.
• Lubricate the cable to improve the sliding effect, pass the sheath "R" fig.
24 over the steel cable until it reaches the cylinder.
• Position the sheath in the holding slots "S" fig. 25 on the side of the mo-
tor.
• Fasten the cord holding plate "T" fig. 25 near to the fixed part of the inter-
nal door handle making sure that the setting elements are positioned in
such a way so as to allow to adjust the tension of the cord afterwards.
• Choose the route for the cord and fasten it to the door panel.
• Make sure the steel ferrules have been inserted and then pass the cord
through the setting nuts and fasten it to the cord holding plate, pull the
cable tight until it reaches the mobile part of the door handle. Fasten the
cable to the handle.
• Tighten the cable by rotating the setting nuts.
• Carry out several trials releasing and blocking the motor from inside and
outside the garage door.
• If your installation requires a double motor, fit the second manual release
cord by following the instructions in the same sequence.
