1-2 Phase - Neutral = Mains power supply
3-4 Flashing light = 24 Vdc max 25W flashing light output
5-6 Electric lock/Suction
cup
= 24Vdc max 250 mA electric lock/suction cup output
7-8 Phototest = Phototest output
9-10 24 Vdc = 24 Vdc max. 200mA services power supply
11 Common = Common for all inputs
12 Sca = Barrier open output (LED on = barrier open; LED off = barrier closed; high
frequency flashing = closing phase; low frequency flashing = opening phase)
13 Cor = Courtesy light output (activated at the start of a cycle and remains active for
60 seconds after the cycle is concluded)
14 Man = Maintenance LED output
15 Sync = Barriers synchronism
16 Stop = STOP input (Emergency, trip, or extreme safety), normally closed type (NC)
or constant 8.2K
Ω
resistance type (heading 0)
17 Foto = NC type input for safety devices (Photocells, pneumatic safety edges)
operational during the closing phase
18 Step-by-Step = Input for cyclic Open – Stop – Close – Stop operation
19 Open = Input for opening movement with cyclic Open – Stop – Open – Stop
operation
20 Close = Input for closing movement with cyclic Close – Stop – Close – Stop
operation
Aerial = Input for radio receiver aerial
Battery = Connection of plug-in card for battery charger

To ensure the safety of the operator and prevent damage to components, while making connections or plugging
in the radio receiver the control unit must be disconnected from the mains power supply and the back-up
batteries (if present).

•
The control unit must be powered via a 3 x 1.5mm
2
cable (phase, neutral and earth); if the distance
between the control unit and earthing system is greater than 30 m an earth electrode must be installed
in the immediate vicinity of the control unit
•
To connect the flashing light and electric lock we recommend using a cable with minimum wire
section of 1 mm
2
•
For connections of the safety low voltage part of the safety circuit use wires with a minimum section of
0.25 mm

; (use shielded cables if the length exceeds 30 m, connecting the shield to ground only on the
control unit side).
•
Pay attention to devices with obliged polarity (flashing light, electric lock, phototest, services, etc.).
•
NC (normally closed) type inputs, when unused, must be jumpered with the "24 Vdc Common"; NO
(normally open) type inputs, when unused, must be left open.
•
Contacts must be strictly mechanical and free of any type of electrical potential; "PNP, "NPN", "Open
Collector" etc. type switching inputs are not permitted.

The control unit can be programmed to operate with two types of STOP input:
•
NC type STOP input: for connection of devices with a normal closed output (factory setting).
•
Constant resistance STOP: for connection of devices with a constant resistance output of 8.2K
Ω
(e.g.
safety edges). In this latter case the control unit measures the resistance connected across the STOP
input and the services common terminal and disables the manoeuvre when the measured value moves
outside the range defined by 8.2K
Ω
+/- 50%.
