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. 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
control unit 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 (only for CITY1-ECD)
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 encoder operation, when in the closed position, both gate
panels must rest against a mechanical stop. Each time the
controller is turned on the gate is closed until the gate panels
touch the mechanical stop in order to realign the encoders.
The limit switch input terminals are used for the encoder
connection. For this reason limit switches and encoders cannot be
connected at the same time.
Connect the encoder signal cables for Motor 1 on terminals
14
and
15
.
Connect the encoder signal cables for Motor 2 on terminals
12
and
13
.
Connect the negative power supply pole for both encoders to
terminal
16
.
Connect the positive power supply pole for both encoders to
terminal
17
.
STOP
For a better safety, you can fit a stop switch that will cause the
immediate gate stop when activated. This switch must have a
normally close contact that will get open in case of operation.
In case the stop switch is operated while the gate is open, the
automatic closing function will always be disabled. To close the
gate again, you will need a start command (if the start function
in pause is disabled, it will be temporarily enabled to allow the
gate release).
