INSTALLATION

Installation of control unit and safety devices must be carried
out with power disconnected.

POWER SUPPLY AND MOTORS

The control unit must be powered by an electric wire protected
by a differential magnetothermic switch in compliance with
current legislation.
The power needed depends on the kind of motor used and can
be one of three kinds:
• 400V three phase
• 230V three phase
• 230V single phase
The following layouts show how the power and cables on the
motor should be connected and how the voltage selection
connector in each case should be set up.
IMPORTANT: before connecting the power supply, make
sure the voltage selection connector has been properly set
up. Incorrect setting could seriously damage the control unit.
400V three phase
230V three phase (compared to the previous layout, only the
voltage selection connector changes)
230V Single phase (in this case, you have to fit a starter
condenser)
Use the W4 and W5 clamps for the earth connection of the
motors to the system's earth.
If the directional movement of the gate is the opposite to the
one required, switch over the W2 and W3 connections.
IMPORTANT: the control unit provides no protection to the
motors. A motor protection device should be installed before
the motor.

BLINKER

900CT-380 control unit provides for a 230V 40W blinker
equipped with intermittence inside.
Connect blinker cables to terminals B1 and B2 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.
