1.2.2 SAFETY BEAMS WITH FUNCTIONING TEST
Through the safety beams’ test, the control unit can verify, before every operation, that there are no short circuits or wrong
activities dangerous for the functionality and safety of the system.
Hence this test grants the system’s safety even if a single damage occurs, as required by the norms EN13241-1 and EN12453. In
order to activate this test it is necessary to follow the procedure “ACTIVATION OF THE SAFETY BEAMS’ TEST” (see page 29), after
having connected the safety beams and the other devices.
1.2.3 SAFETY EDGE with normally closed contact or resistive 8,2 K contact.
SAFETY BEAMS TERMINALS
DESCRIPTION
CONNECTION TERMINALS
POWER SUPPLY
TRANSMITTERS
(refer to the instructions booklet of
the safety beams in use)
The power supply of the transmitting safety
beam is separated by that of the receiving one
and must be withdrawn from the output line
(TEST) of the control unit. It is not necessary to
follow the polarity of the two wires.
They must be connected to the termi-
nals 10 and 12 (TEST).
POWER SUPPLY RECEIVERS
(refer to the instructions booklet of
the safety beams in use)
The power supply of the receivers safety beam
is separated by that of the receiving one and
must be withdrawn from the output line
(24Vac) of the control unit. It is not necessary
to follow the polarity of the two wires.
They must be connected to the termi-
nals 10 and 11 (24Vac).
SAFETY BEAM CONTACT
Normally closed (Refer to the recei-
ving safety beam’s manual)
The contact NORMALLY CLOSED of
the receiving safety beam must be
connected to the terminals 8 (com)
and 9 (photo).
EDGE TYPE
DESCRIPTION
CONNECTION TERMINALS
EDGE WITH NORMALLY
CLOSED CONTACT
It works during the closure with an immediate
inversion of the opening movement for 2 sec.
During the opening it stops the movement.
It has to be connected to the terminals
7 (edge) and 8 (com).
Place the dip 4 in OFF position!
EDGE WITH 8,2K RESISTIVE
CONTACT

inversion of the opening movement for 2 sec.
During the opening it stops the movement.
- It has to be connected to the
terminals 7 (edge) and 8 (com).
- Safety beam power supply: terminals
11 et 12 [24Vac].
