6.1.3. F
AlsAFe
Terminal “
4
”. Connect to this terminal, the negative terminal of the photocell transmitters. By making this
connection, the control unit, before every manoeuvre, runs a test on the photocells, controlling correct operation. If
you use photocells, this terminal
must be
connected to ensure the control unit operates correctly.
6.1.4. p

supply
For
Accessories
Terminals “
5
&
6
”. 24 Vdc output max. 500 mA for feeding the external accessories.
• Maximum load of this output is 500 mA.
• Observe the power supply polarity.

lights
Terminals “
7
&
10
”. Output 24 Vdc max.15 W. The wires feeding the luminous strip should be connected to these
terminals. The operation of the luminous strip is defined by using dip-switch 5 - see paragraph 7.
Terminal “0” is the negative polarity output.
6.2.2. i
ndicAtor
light
Terminals “
8
&
10
”. Output 24 Vdc max. 5 W. An indicator light, if any, should be connected to these terminals. The
indicator light makes it possible to see the beam status from a remote position, e.g. a porter’s lodge - details:
Beam opening is identified by fast flashing.
When the beam is open, the indicator light stays lighted on a steady light-beam.
Beam closing is identified by slow flashing.
When the beam is closed, the indicator light stays OFF.
• 24 Vdc max. 5 W lamps can be connected to this output.
• Terminal “0” is the negative polarity output.
6.2.3. F
lAshing
light
Terminals “
9
&
10
”. Output 24 Vdc max.15 W. A steady beam flashing light is connected to these terminals - flashing
is controlled by the control unit. The flashing light is active while the beam is moving, whereas when the beam is idle,
whether open or closed, it stays OFF. Pre-flashing of 0.5 sec was inserted before the beam opening manoeuvre, to
signal that the beam is about to move. In addition to signalling beam movement, the flashing light signals - by a
series of flashes - that the beam is being powered by the buffer battery (optional).
Terminal “0” is the negative polarity output.
6.2.4. c
lose
Terminals “
10
&
11
”. Normally open contact. Connect, between these 2 terminals, any pulse generator (e.g.
push-button, key selector, etc..) which, by closing the contact, commands beam closure only. The status of this
input is signalled by LED “
DL1
”.
• The
CLOSE
command is not active during programming.
• If there are several pulse generators, they must be connected in parallel.
6.2.5. o
pen
Terminals “
10
&
12
”. Normally open contact. Connect, between these 2 terminals, any pulse generator (e.g.
push-button, key selector, etc..) which, by closing the contact, commands beam opening only. The status of this
input is signalled by LED “
DL2
”.
• The
OPEN
command is not active during programming.
• If there are several pulse generators, they must be connected in parallel.
6.2.6. o

Terminals “
10
&
13
”. Normally open contact. Connect, between these 2 terminals, any pulse generator (e.g.
push-button, key selector, etc..) which, by closing the contact, commands beam opening and/or closing. The
behaviour of this input is defined by dip-switch 2, see paragraph 7. The status of this input is signalled by LED “
DL3”
.
• If there are several pulse generators, they must be connected in parallel.
6.2.7. s
top
Terminals “
10
&
14
”. Normally closed contact. Connect, between these 2 terminals, any pulse generator (e.g.
push-button, key selector, etc..) which, by opening the contact, must command immediate stop of the beam and
the de-activation of any automatic re-closure. To resume the normal programmed cycle after this contact has been
activated, use any pulse generator which commands the opening and/or closing of the beam. The status of this
input is signalled by LED “
DL4
”.
• If there are several pulse generators, they must be connected in series.
