844R Reversible AUTOMATED SYSTEM
Read the instructions carefully before using the product and
store them for future use.
GENERAL SAFETY REGULATIONS
If correctly installed and used, the 844R Reversible automated
system will ensure a high degree of safety.
Some simple rules on behaviour can prevent accidental trouble:
-
Do not stand near the automated system, and do not allow
children, persons or things to do so, especially when it is
operating.
-
Keep radio-controls, or any other pulse generators that could
involuntarily activate the automated system, well away from
children.
-
Do not allow children to play with the automated system.
-
Do not willingly obstruct gate movement.
-
Prevent any branches or shrubs from interfering with gate
movement.
-
Keep warning-lights efficient and easy to see.
-
Activate the gate manually only in the event of a power cut.
-
In the event of malfunctions, release the gate to allow access
and wait for qualified technical personnel to do the necessary
work.
-
When you have set manual operation mode, cut power to
the system before restoring normal operation.
-
Do not in any way modify the components of the automated
system.
-
Do not attempt any kind of repair or direct action whatever
and contact qualified FAAC personnel only.
-
At least every six months: arrange a check by qualified
personnel of the automated system, safety devices and earth
connection.
DESCRIPTION
The 844R Reversible automated system is ideal for controlling
vehicle access areas of medium transit frequency.
The 844 R Reversible automated system for sliding gates is an
electro-mechanical operator which transmits movement to the
sliding gate via a rack and pinion appropriately coupled to the
leaf.
The operation of the sliding gate is controlled by an electronic
control unit which can be built-in on board (462DF) or
connected in a remote position (578D or 462DF).
When, with the gate closed, the unit receives an opening
command by a radio-control or from another suitable device, it
activates the motor until the opening position is reached.
If automatic operating mode was set, the gate re-closes
automatically after the selected pause time has elapsed.
If the semi-automatic mode was set, a second pulse must be
sent for re-closing.
An opening pulse during re-closing, always causes movement
to be reversed.
A stop pulse (if supplied) always stops movement.
For details on sliding gate behaviour in different function logics,
consult the installation technician.
The automated systems include accessories and safety devices
(photocells, edges) that prevent the gate from closing when
there is an obstacle in the area they protect.
Manual opening is always possible, except in case of a fault. In
this case, the release system must be remedied.
The gearmotor has an adjustable mechanical clutch which,
when coupled to an electronic device, provides the necessary
anti-crushing safety, guaranteeing motion reversing for 2 sec.
both during closing and opening.
A magnetic sensor detects transit of the markers on the rack,
which correspond to the travel limit positions.
The warning-light indicates that the gate is currently moving. A
handy manual release facility makes it possible to move the
gate in the event of a fault.
MANUAL OPERATION
If the gate has to be moved manually, due to a power-cut, it is
sufficient to push or pull it, because the reversible motor enables
the gate to be moved manually.
If the gate has to be moved manually due to a fault in the
automated system, use the release device as follows:
1)
Open the electric lock with the key, checking if the gate is
free to move.
2)
Open the protective door and fit the supplied key in the
lock as shown in Fig. 1.
3)
Turn the key clockwise and pull the release lever as shown in
Fig. 2.
4)
Open and close the gate manually.
RESTORING NORMAL OPERATION MODE
To prevent an involuntary pulse from activating the gate during
the manoeuvre, cut power to the system before re-locking the
operator.
1)
Re-close the release lever.
2)
Turn the key counter-clockwise.
3)
Remove the key and close the lock protection door.
4)
Move the gate until the release device meshes.
