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
City4-120V
) electric line, protected by a
differential magnetothermal switch complying with the law
provisions in force.
Connect power supply cables to terminals
L
and
N
of
City4
control unit.
MOTOR
City4
control unit can control one alternate current
asynchronous motor. Max. total power is 700W.
Connect motor cables as follows:
• opening cable to terminal
G3
• closing cable to terminal
G5
• common return cable to terminal
G4
m
WARNING:
• In case it has not yet fitted, a start capacitor is required;
connect the start capacitor between terminals
G3
and
G5
.

WARNING (USING HYDRAULIC MOTORS):
• If using hydraulic motor, the following function could not
work properly: Soft start, Slowing down and Obstacle sensor.
In this case, such functions should be disabled from menu.
• Read carefully the working times self-learning procedure,
described in the paragraph “QUICK CONFIGURATION”, paying
particular attention to the points where the procedure to be
followed in case of disabled obstacle sensor is described.
BLINKER
City4
control unit provides for a 230V 40W (120V – 40W for
model
City4-120V
) blinker equipped with intermittence inside.
Connect blinker cables to terminals
G6
and
G7
of the control
unit.
COURTESY LIGHTS
Thanks to the output COURTESY LIGHT the control unit
City4
allows the connection of an electric appliance (e.g. courtesy
light or garden lights), controlled automatically or by means of
the special transmitter key.
The output COURTESY LIGHT is a simple N.O. contact with no
power supply.
Connect the cables to terminals
G1
and
G2
.
ELECTRIC LOCK
An electric lock can be assembled on the gate, to ensure a
good closing of doors. Make use of a 12V lock. Connect lock
cables to terminals
P13
and
P14
of the control unit.
PHOTOCELL
City4
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.
The photocells are active only during the closing phase and, if
required, with standstill gate. In case intervention, the control
unit immediately opens the gate, not waiting for the release.
• Connect power supply cables of photocells transmitter
between terminals
P11
and
P12
of the control unit.
• Connect power supply cables of photocells receiver between
terminals
P10
and
P11
of the control unit.
• Connect receiver output between terminals
P6
and
P9
of the
control unit. Use outputs having normally closed contact.
