4 - CONTROL UNIT
PD12 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:
• Power supply protected from short circuits within the
controller, on the motors and on the connected accessories.
• Adjustment of the power by partializing the current.
• Detecting obstacles by monitoring the current on the motors
(current sensing probe)
• Automatic learning of the operation time
• Obstacle sensor: a system allowing detection of whether
movement of the gate is impeded by an obstacle.
This system is based on measurement of the current absorbed
by the motor: an unexpected increase in current absorption
indicates the presence of an obstacle.
• Tests for safety devices (photocells and safety ribbons) 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.
• The device can operate without mains power, by using the
optional battery pack (code 161212).
• Low voltage output that can be used for a signal light or a
24V flashing light.
• Auxiliary relay with programmable logic for courtesy light,
flashing light or other use.
• ENERGY SAVING function
4.1 - ENERGY SAVING FUNCTION
This function is useful for reducing the energy consumption of
the automation device while in stand-by mode.
If the function is enabled, the control unit will enter ENERGY
SAVING mode under the following conditions:
• 5 seconds after completion of an operational cycle
• 5 seconds after an opening (if automatic closure is not
enabled)
• 30 seconds after exiting the programming menu
In ENERGY SAVING mode, power to the accessories, display and
flashing lights is deactivated.
ENERGY SAVING mode is exited:
• If an operational cycle is activated
• If one of the menus is accessed
4.2 - INSTALLATION
Installation of control unit and safety devices must be carried out
with power disconnected.
4.3 - CONNECTION OF THE MOTOR
The control unit is supplied already connected to the MASTER
motor.
The SLAVE motor (if used) should be connected to terminals
K1 - K2 - K3, following the polarity indicated on the labels
attached to the control unit and the Slave motor itself.
