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.
Connect type 1 safety ribbons cables between terminals 9 and 11
of the control unit.
Connect type 2 safety ribbons cables between terminals 10 and
11 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 19 and 18 of the
CITY1-ECD.
Otherwise, connect them between terminals 17 and 18.
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 20 and 21 of the control unit.

END OF STROKE

CITY1-ECD supports the two following kinds of end of stroke:
• end of stroke in series of motor winding.
• end of stroke equipped with a normally close switch that will
be opened as soon as the door reaches its position desired.
The control unit automatically recognizes ends of stroke in-series
of the motor windings so no connection or programming is
required.
Ends of strokes equipped with a normally close switch must be
connected to the control unit terminal board as follows:
• opening end of stroke in door 1 between terminal 12 and 16.
• closing end of stroke in door 1 between terminal 13 and 16.
• opening end of stroke in door 2 between terminal 14 and 16.
• closing end of stroke in door 2 between terminal 15 and 16.

ENCODER

With CITY1-ECD, you can use encoder-equipped motors to
control the exact position of the gates. Furthermore, the encoders
allow you to detect if the gate panels jam in an improper position
due to obstacles.
For correct operation of the encoders, it is essential
that both gate leaves rest against a mechanical stop when
in the closed position. In order to realign the encoders,
each time the control unit is turned on, the gate is closed
until the gate leaves come to a stop on the mechanical
stop.
Connect the encoders using the limit switch input terminals.
Hence, it is not possible to connect 2 motors with limit switches
and encoders at the same time.
WARNING: the encoders must be connected as
indicated below. Improper connection of the black cable
may damage the device.
DUAL LEAF GATES
• Connect the negative feeds (BLACK cable) for both encoders
to terminal 16 (COM)
• Connect the positive feeds (RED cable) for both encoders to
terminal 17 (24VAC)
• Connect the motor 1 encoder signal cables (BLUE / WHITE)
to terminals 14 (FCA2) and 15 (FCC2)
• Connect the motor 2 encoder signal cables (BLUE / WHITE)
to terminals 12 (FAC1) and 13 (FCC1)
