PHOTOCELL2 and STOP, are always on while those on the com-
mand inputs, STEP-BY-STEP, OPEN-TIMER and CLOSE, are usually
off.
Since the current absorbed by a DC motor is in proportion to the
force it is subject to, developing an obstacle detection system is very
easy. During movement, the current absorbed by the motor is meas-
ured; when it exceeds a certain limit (adjustable with the trimmer) the
safety system is activated which causes movement to stop with the
aid of the brake (removing the residual part of accumulated kinetic
energy); then, if one of the automatic functioning modes is active,
a movement in the opposite direction starts. To increase the level
of safety still further, if the STOP_AMPERE system comes into play
three consecutive times without ever reaching any of the natural ends
of the movement, a final STOP is carried out.

Installation
When installing the road boom gate, all the instructions given in the
enclosed instruction manual must be followed.
It is necessary to underline that there are standards, laws and regula-
tions that establish limits and ways to make systems: please comply
strictly with all the applicable standards.
CAUTION! - Do not install the boom gate unless all the
standards regarding the automatic gate category have been
complied with!!
Install all the control (key selector switch or push button panel) and
safety devices (emergency stop, photoelectric cells, sensitive edges
and flashing lights) after which do the wiring following the diagram:
Then make the electrical connections per the following diagram.

Electrical
connections
Here is a brief description of the possible connections on the unit to
the outside:
1-2
230 V AC = 230 V AC 50/60 Hz power
3-4
Flashing light = Output for connection to the 24 V DC
flashing light, maximum lamp power: 25 W
5-6
24 V DC = 24 V DC output for supplying accessories
(Photocell, Radio, etc.) maximum 200 mA
7
Common = Common for all inputs (terminal 6 can also be
used as the Common)
8
Courtesy light = 24 V DC output for the courtesy light,
maximum output power 10 W
9
Bar open indicator = 24 V DC output for bar open
indicator light, maximum indicator power 10 W
10
STOP = Input with STOP function (Emergency, shutdown
or extreme safety)
11
Photocell = Input for safety devices (Photocells,
pneumatic edges)
12
Photocell 2 = Input for safety devices with triggering in
the opening phase (Photocells, pneumatic edges)
13
Step by step = Input for cyclic functioning (OPEN STOP
CLOSE STOP)
14
Open-Timer = Input for opening (which can be timer
controlled)
15
Close = Input for closing
41-42
2° Radio channel = Second radio receiver channel input
(as applicable)
43-44
Antenna = Input for the radio receiver antenna
The remaining connections are done in the factory but for the sake
of completeness here is the list:
TRANSFORMER PRIMARY = Primary of the power transformer
TRANSFORMER SECONDARY = Secondary of the power transformer
MOTOR = Output for 24 V DC motor connection
There are an additional two slots for optional cards:
RADIO = Slot for Nice radio receivers
CHARGE = Slot for battery charge card
3.1 -
Electrical hookup
CAUTION! - To safeguard the operator and to prevent damag-
ing components when carrying out the connections, whether in low
voltage (230 V) or extra low voltage (24 V), or when plugging in the
cards: the unit must, under no circumstances, be electrically
powered
We recommend waiting until installation is complete to plug in the
optional cards RADIO or CHARGE and only after having checked
that the system is working properly. The optional cards are not nec-
essary for the working of the system and if they are used they make
troubleshooting more complex.
We would also like to remind you that if the inputs of the NC (Nor-
mally Closed) contacts are not used, they should be jumpered; if
there is more than one then they should be placed in SERIES with
one another; if the inputs of the NO (Normally Open) contacts are
not used they should be left free and if there is more than one then
they should be placed in PARALLEL with one another. As for the
contacts, they must only be the mechanical type and free from any
