MANUAL RELEASE MECHANISM (fig.6)
Manual release should only be carried out when the motor has stopped
due to blackouts.
Releasing the mechanism externally (only with a release cable
installed). Rotate the handle "A" through 90°. Hold it in this position and
press on the door to open it. The release mechanism works immediately.
Rotating the handle frees the reduction motor gears.
Locking the mechanism externally
Move the door to the desired position and rotate the handle "A"
towards the closed position. The reduction motor gears may not lock
immediately but it can be locked manually by pressing on the door or
by reactivating the motor.
Releasing the mechanism internally
Operate the lever "L" (fig.6a) until it reaches the release position (fig.6c)
where it will remain thanks to an anti return mechanism.
Locking the mechanism internally
Lightly press, in the opposite direction, on the lever "L" (fig.6c) to over-
come the anti-return mechanism. The presence of the spring will make
the mechanism automatically return to the blocked position (fig. 6a). The
reduction motor gears may not lock immediately but they can be locked
manually by pressing on the door or by reactivating the motor.

ELECTRICAL CONNECTION

Before connecting the appliance make sure that the voltage and fre-
quency rated on the data plate conform to those of the mains supply.
• The appliance works off a 24V direct current power supply (see
electrical connection).
• Do not use cables with aluminium conductors; do not solder the ends
of cables which are to be inserted into the binding posts.
• During the installation make sure that cables do pass near the night
light (230V 40W).
• Pass the 24Vdc motor power cable and travel limit cable (4 x 1,5)
through the clamp ring before wiring it to the terminal board. Use the
second clamp ring for the 230Vac night light cable (2 x 1 + T). The
two cables and terminal boards have been separated so there can
be no accidental contact between the two.
• Use insulted channelling to run the cables along the garage door.
• User the lowest hole on the motor support bracket "A" (fig.9) to pass
the cable into the appliance.
• To connect the appliance follow the wiring diagram on page 8.
• The microswitch located on the an eventual second motor can be
used as a closing direction travel limit (see wiring diagram fig.8).
For the correct operation of the appliance you must use
a Cardin direct current electronic programmer from the series
PRG85CC (with batteries and a battery charger) or PRG850C
(without batteries and without a battery charger) suitable for driving
one motor or two motors in parallel.
