SAFETY RIBBONS

The control unit considers two kinds of safety ribbons,
depending on the terminal to which they are connected:
• Type 1 (fixed): they are mounted on walls or on other fixed
obstacles that are approached by the gate doors during the
opening phase. When type 1 safety ribbons operate during
the gate opening phase, the control unit will close the doors
for 3 seconds, then it stands still; when type 1 safety ribbons
operate during the gate closing phase, the control unit will
stand still immediately. The direction of the gate at next
command of START or PEDESTRIAN START depends upon the
parameter STOP (it inverts or continues the motion).
If the input STOP is disabled, the command makes the motion
continue in the same direction.
• Type 2 (mobile): they are mounted to the door ends.
When type 2 safety ribbons operate during the gate opening
phase, the control unit will stand still immediately; when
type 2 safety ribbons operate during the gate closing, the
control unit will open the doors for 3 seconds, then it will
stand still. The direction of the gate at next command of
START or PEDESTRIAN START depends upon the parameter
STOP (it inverts or continues the motion). If the input STOP
is disabled, the command makes the motion continue in the
same direction.
Both the input can manage the classic safety edge with n.c.
contact and the conductive rubber safety edge with 8,2 kohm
nominal resistance.
Connect type 1 safety ribbons cables between terminals
L9 (EDGE1) and L11 (COM) of the control unit.
Connect type 2 safety ribbons cables between terminals
L10 (EDGE2) and L11 (COM) of the control unit.
In order to meet the requirements of the EN12978 rules, it is
necessary to install safety edges controlled by a control unit
continuously checking the proper working. If using control units
suited to the test by power outage, connect the power supply
cables of the control unit between terminals K7 (-) and
K8 (+Test) of the control unit.
Otherwise, connect them between terminals K6 (+) and K7 (-).
WARNING:
• Make use of safety ribbons having outputs with normally
close contact.
• Outputs of same kind safety ribbons must be connected in
series.

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 K9 and K10 of the control unit.

LIMIT SWITCH AND ENCODER

The CITY2+ controller can control the gate's travel using a limit
switch and/or an encoder.
CAUTION: The use of these devices is strongly
recommended to ensure that the gate opens and closes
correctly.
The speed of operation of the DC motors can be conditioned by
variations in mains power, atmospheric conditions, and friction of
the gate.
Furthermore, encoders also allow the controller to determine if
the gate stops in an irregular position due to an obstacle.
For encoder operation, it is required that the closure position for
each section of the gate be detectable using a limit switch sensor
or a mechanical stop.
Each time the controller is turned on, to realign the encoders, the
gate is closed until it reaches the limit switch or the mechanical
stop.
GATES WITH TWO PANELS
For gates with two panels, limit switches and encoders share the
same terminals so it is not possible to install both of these devices
at the same time.
PLEASE NOTE: refer to the motor manual
Installation of limit switch
• Connect the open limit switch to motor 1 using terminals
K1 (FCA1) and K5 (COM)
• Connect the close limit switch to motor 1 using terminals
K2 (FCC1) and K5 (COM)
• Connect the open limit switch to motor 2 using terminals
K3 (FCA2) and K5 (COM)
• Connect the close limit switch to motor 2 using terminals
K4 (FCC2) and K5 (COM)
Installation of encoders
• Connect the power source for both encoders to terminals
K5 (COM) and K6 (+)
• Connect the encoder outputs to motor 1 using terminals
K3 (FCA2) and K4 (FCC2)
• Connect the encoder outputs to motor 2 using terminals
K1 (FCA1) and K2 (FCC1)
Check that the two pairs of wires have been correctly
connected and after installation proceed as follows:
1. Disable encoder operation (Enco menu)
2. Set a meaningful open delay (r.AP menu)
NOTE: The default settings in the controller satisfy points
1 and 2.
3. Give a START command:
- If both gate panels move, the wires are connected correctly
- If Err7 appears on the display once panel 1 starts to move,
invert the wires connected to terminals K3 (FCA2) and
K4 (FCC2)
- If Err7 appears on the display once panel 2 starts to move,
invert the wires connected to terminals K1 (FCA1) and
K2 (FCC1)
