DESCRIPTION OF THE CONTROL
UNIT
The digital control unit Pd8 is an innovative V2 S.p.A. product
that guarantees a safe and reliable automation of sliding gates.
The Pd8 has been designed to realize a product that meets all
kind of requirements, with a highly versatile control unit that
satisfies all the necessary requirements for a functional and
efficient installation.
Pd8 is provided with a display that, not only makes
programming simple, but also allows a continuous monitoring of
the input statuses; in addition, thanks to a menu structure, the
working schedule and the operation logic can be set easily.
In compliance with the European standards concerning electrical
safety and electromagnetic compatibility (EN 60335-1,
EN 50081-1 and EN 50082-1) it has been equipped with the low
voltage circuit total electric insulation (motors included) from the
network voltage.
Other characteristics:
• Automatic control for the null current relay switch.
• Power adjustment with wave shutting.
• Obstacle detection by means of monitoring start condenser
voltage.
• Automatic learning of the operation time.
• Tests for safety devices (photocells and triacs) before each
opening.
• Deactivation of safety inputs through the configuration
menu: no jumper is required for terminals concerning safety
devices that have not been installed, yet. You will only need
to disable this function from its relevant menu.
INSTALLATION
Installation of control unit and safety devices must be carried out
with power disconnected.
POWER SUPPLY
The control unit must be fed by a 230V - 50Hz (120V - 50/60Hz
for the model Pd8-120V) electric line, protected by a differential
magnetothermal switch complying with the law provisions in force.
Connect power supply cables to terminals 18 and 19 of Pd8
control unit.
MOTOR
Pd8 control unit drives an asynchronous alternate current motor.
Max. available power is 700W.
The motor comes connected already to terminals 15, 16 and 17
by means of a polarized connector.
m
CAUTION: Never reverse the connector.
BLINKER
Pd8 control unit provides for a 230V 40W (120V - 40W for
model Pd8-120V) blinker equipped with intermittence inside.
Connect blinker cables to terminals 13 and 14 of the control
unit.
PHOTOCELLS
The control unit considers two kinds of photocells, depending on
the terminal to which they are connected:
• Photocell 1: that is to say, photocells installed on the gate
inner side, which are active both during the opening and the
closing phase. When photocells 1 operate, the control unit
stops the gate; as soon as the photocell beam is free, the
control unit will open the gate completely.
m
WARNING: Type 1 photocells must be installed so that
they completely cover the opening area of the gate.
• Photocell 2: that is to say, photocells installed on the
external gate side and which are active during the closing
phase only. When photocells 2 operate, the control unit
opens the gate immediately, without waiting for release.
Pd8 control unit supplies a 24VAC power supply to photocells
and it can perform a photocell operation test before starting the
gate opening phase. Photocell power terminals are protected by
an electronic fuse that stops current in case of overload.
• Connect power supply cables of photocells transmitter
between terminals 11 and 12 of the control unit.
• Connect power supply cables of photocells receiver
between terminals 10 and 11 of the control unit.
• Connect receiver output of photocells 1 between terminals 5
and 9 of the control unit and receiver output of photocells
2 between terminals 6 and 9 of the control unit.
Use outputs having normally closed contact.
m
WARNING:
• if several couples of same kind photocells are mounted,
their outputs must be connected in series.
• In case of reflection photocells, power supply must be
connected to terminals 11 and 12 of the control unit to
carry out the operation test.
