DESCRIPTION OF THE CONTROL UNIT
The digital control unit Pd8 is an innovative V2 ELETTRONICA
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 700 W. The motor comes
connected already to terminals 15, 16 and 17 by means of a
polarized connector.
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.
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.
