Safety Ribbons; End Of Stroke; Stop - V2 ELETTRONICA City1 Manual De Instrucciones

WARNING:
• if several couples of same kind photocells are mounted,
their outputs must be connected in series.
• In case of reflection photocells, power supply must be
connected to terminals 19 and 18 of the control unit to
carry out the operation test.

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.

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:
• end of stroke in door 1 opening phase between terminal 12
and 16.
• end of stroke in door 1 closing phase between terminal 13
and 16.
• end of stroke in door 2 opening phase between terminal 14
and 16.
• end of stroke in door 2 closing phase between terminal 15
and 16.

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).
Connect the stop switch cables between terminal 5 and 6 of
the control unit.
The stop switch function can be activated by means of a
remote control stored on channel 3 (see relevant instructions
of MR1 receiver). The command STOP from remote is operative
also if the input STOP of the terminal board is disabled.
