6.6 - 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. If the STOP input is disabled, the
control restarts motion in the same direction it was travelling prior
to the intervention of the edge.
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.
If the STOP input is disabled, the control restarts motion in the
same direction it was travelling prior to the intervention of the
edge.
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.
6.7 - LOW VOLTAGE LIGHT (24V)
The CITY2+ controller has a 24 V DC output that allows
connections to a load up to 15 W.
This output can be used to connect a signal light that indicates
that status of the gate, or for a low voltage flashing light.
Connect the low voltage signal light or flashing light wires to
terminals Z1 (+) and Z2 (-).
m
CAUTION: Pay attention to the polarity of the
connected device if necessary.
6.8 - 230V COURTESY LIGHT OR
FLASHING LIGHT
Thanks to the output COURTESY LIGHT the control unit 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 courtesy light terminals can be alternatively used for a 230V
flashing light with integrated flasher.
CAUTION: When the controller is operating on battery
power, the 230 V flashing light will not work.
The output COURTESY LIGHT is a simple N.O. contact with no
power supply (the maximum rating of the relay is 5A - 230V).
Connect the cables to terminals B1 and B2.
6.9 - 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.
