J7 Terminal board - Power supply (fig. 23)

POWER SUPPLY (terminals PE-N-L):

PE:

Earth connection

N :

Power supply ( Neutral )

L :

Power supply ( Line )

NB.:

For correct operation, the board must be connected to

the earth conductor in the system. Install an adequate
differential thermal breaker upstream of the system.

To install several partial opening pulse generators,
connect the N.O. contacts in parallel (fig.35).

FSW OP - Opening safety devices contact (terminal 3):

The

purpose of the opening safety devices is to protect the
leaf movement area during opening. During opening, in
the

A-AP-S-E-EP

logics the safety devices reverse the

movement of the gate, or stop and restart the movement
when it is released (see advanced programming in
Chpt. 5.5.2). During the opening cycle in logicsthe

B, C

and

B/C

, they interrupt movement. They never operate

during the closing cycle.
If the

Opening safety devices

are engaged when the

gate is closed, they prevent the opening movement.
To install several safety devices, connect the N.C.
contacts in series (fig.25).

NB.: If no opening safety devices are connected, jumper
connect inputs FSW OP and -TX FSW

(fig. 26).

FSW CL - Closing safety devices contact (terminal 4):

The

purpose of the closing safety devices is to protect the
gate movement area during closing. During closing, in
the

A-AP-S-E-EP

logics, the safety devices reverse the

movement of the gate, or stop and reverse the
movement when it is released (see advanced
programming in Chpt. 5.5.2). During the closing cycle in
logics

B, C

and

B/C

, they interrupt movement. They

never operate during the opening cycle. If the

Closing

safety devices

are engaged when the gate is open,

they prevent the closing movement.
To install several safety devices, connect the N.C.
contacts in series (fig.25).

NB.: If no closing safety devices are connected, jumper
connect terminals FSW CL and -TX FSW

(fig. 26).

STOP

- STOP contact (terminal 5):

any device (e.g. a push-

button) which, by opening a contact, stops gate
movement.
To install several STOP devices, connect the N.C.
contacts in series (fig. 25).

NB.:

If STOP devices are not connected, jumper

connect the

STOP

and

terminals.

SAFE -

EDGE safety device contact (terminal 6):

The purpose of

the "edge" safety device is to protect the leaf movement
area during opening/closing. In all logics, during opening
and closing, the safety device reverses gate movement
for 2 seconds. If the safety devices operate again during
the 2-seconds reversing time, it stops movement (STOP)
without any reversing.
If the

Edge safety device

is engaged while the gate is

closed or open, it prevents movement.
To install several safety devices, connect the N.C.
contacts in series (fig.25).

NB.: If edge safety devices are not connected, jumper
connect the SAFE and - inputs

(fig. 26).

Negative for power supply to accessories (terminals 7
and 8)

24 Vdc - Positive for power supply to accessories
(terminals 9 and 10)

Important:

Accessories max. load is 500 mA. To calculate

absorption values, refer to the instructions for individual
accessories.
