DESCRIPTION OF THE CONTROL UNIT
The CITY11 control unit is an innovative V2 product guaranteeing
safety and reliability for swing gate automation.
The CITY11 design has been aimed at creating a product which
adapts to suit all needs, thus obtaining an extremely versatile
control unit satisfying all the necessary requirements for a
functional and efficient installation.
• 230V - 50Hz or 120V - 60Hz power supplies, depending on the
model, for 2 single phase motors (700W global).
• Output for 12V electric lock.
• Input for keyswitch or push-button.
• Input for safety photocell.
• Input for safety edge, capable of handling standard edges
with switch normally closed and conductive rubber edges with
nominal resistance of 8.2 kOhms.
• Pre-opening safety device testing.
• Dip-switch programmable operational logic.
• Adjustment of motor power and operation time by means of a
trimmer.
• Quick plug-in connector for inserting a MR series receiver.
• LED monitoring of inputs.
• Courtesy light output.
• IP55 casing
INSTALLATION
Installation of the control unit, the safety devices and accessories
must be performed with the power supply disconnected.
POWER SUPPLY
The control unit must be powered by means of a 230 V - 50 Hz
or 120 V - 60 Hz power line, depending on the model, protected
by a differential magnetothermal switch in compliance with legal
regulations.
Connect the power cables to the control unit
L
and
N
terminals.
MOTORS
The control unit can control one or two asynchronous AC motors.
If the control unit is used to control only one motor, then this
must be connected to the terminals relating to motor 1.
Connect the cables for motor 1 as follows:
• Opening cable to terminal
K3
• Closing cable to terminal
K5
• Common return cable to terminal
K4
• Start-up capacitor between terminals
K3
and
K5
Connect the cables for motor 2 (if present) as follows:
• Opening cable to terminal
K6
• Closing cable to terminal
K8
• Common return cable to terminal
K7
• Start-up capacitor between terminals
K6
and
K8
PHOTOCELLS
The control unit has a 24VAC power supply for photocells with
switch normally closed, and can perform an operational test
before to starting the gate opening procedure.
The photocell can be used with two settings:
1. Photocell always active:
Intervention of the photocell during opening or closing causes
the gate to stop. When the photocell restores, the gate re-
opens completely.
2. Photocell NOT active during opening:
Intervention of the photocell during opening is ignored.
Intervention of the photocell during closing causes the gate to
re-open completely.
Independently of the setting selected, when the gate is paused
while opening, the time count for any automatic re-closure will
only start after the photocell restores.
• Connect the photocell transmitter power cables between
terminals
L8
(GND) and
L9
(+) on the control unit.
• Connect the photocell receiver power cables between terminals
L8
(GND) and
L7
(+) on the control unit.
• Connect the photocell receiver output between terminals
L4
and
L6
on the control unit.
SAFETY EDGES
The control unit has an input for controlling safety edges; this
input is capable of controlling standard edges with switch
normally closed and conductive rubber edges with nominal
resistance of 8.2 kOhms.
Edges can be used with two settings:
1. Edge always active:
Intervention of the edge during opening or closing causes
inversion of the direction of movement in order to free the
body that caused the edge to intervene. The gate stops after
approx. 3 seconds.
2. Edge NOT active during opening:
Intervention of the edge during opening is ignored.
Intervention of the edge during closing causes the gate to
re-open completely.
Independently of the settings selected, any subsequent automatic
re-closure will be cancelled.
Standard edge with switch normally closed:
connect the edge
cables between terminals
L5
and
L6
on the control unit.
In order to satisfy the requirements of standard EN12978, it
is necessary to install safety edges with a control unit which
constantly monitors correct operation. If control units are used
with the option of running tests by means of interrupting the
power supply, connect the control unit power supply cables
between terminals L8 (GND) and L9 (+).
Conductive rubber edge:
connect the edge cables between
terminals
L5
and
L6
on the control unit.
m
PLEASE NOTE: operational testing on edges is
reserved for standard edges (only if equipped with suitable
control units).
DO NOT enable testing if conductive rubber edges are used
or standard edges used without a suitable control unit for
controlling function.
