sure safety devices is to protect the gate movement
area during closing.
If the safety devices are tripped during closure, gate
movement is reversed, while they have no effect dur-
ing opening. If tripped when the gate is open or paus-
ing, closing safety devices prevent its closing.
To install several safety devices, connect the N.C. con-
tacts in series.
Ü
If closing safety devices are not connected, link
this input to the common contact (terminal 5) via a
jumper.
5 =
Common contact for commands
6 =

Max load of accessories is 500 mA.
To calculate absorption values, refer to the instruc-
tions for individual accessories.
9 =
Warning light output (24 Vac)
The maximum load of the warning light is 5 W.
For instructions on operation of the warning light, con-
sult microswitches programming.
Ü
If you cut out jumper LK1, you obtain a voltage free
contact between terminals 8 and 9 (see fig.24).

Install by fitting the accessory cards so that their components side
faces the inside of the 844 T electronic appliance.
Insert and remove the cards after cutting power.
5.2.2. TERMINAL BLOCK J2 (low voltage)
1 = OPEN A (N.O.) – Total opening
This is any pulse generator with N.O. contact which,
when activated, produces a gate opening movement.
In A, E and S logics, it commands both opening and
closing.
To install several Open A devices, connect N.O. con-
tacts in parallel.
2 =
OPEN B (N.O.) – Pedestrians Opening / Closing
This is any pulse generator with N.O. contact which,
when activated in logics A, E and S, produces a gate
opening movement for pedestrians. In B and C logics,
it commands a closing movement.
To install several Open B devices, connect N.O. con-
tacts in parallel.
3 =
STOP command (N.C.)
This is any device (e.g. a push-button) which, by open-
ing a contact, stops gate movement.
To install several stop devices, connect the N.C. con-
tacts in series.
Ü
If Stop devices are not connected, link the input to
the common contact (terminal 5) via a jumper.
4 =
FSW closure safety devices contact (N.C.)
Safety devices are all devices (photocells, sensitive
edges, magnetic coils) with N.C. contact, which, if
there is an obstacle in the area they protect, operate
to interrupt gate movement. The purpose of the clo-

12 = Opening limit switch (N.O.)
13 = Closing limit switch (N.O.)
N.B.: terminals 10-11-12-13 should be connected to the 844
INTERFACE card (supplied with gearmotor), observing
the diagram in Fig.20.
