Safety Ribbons; End Of Stroke - V2 CITY6 Mode D'emploi

• Photocell 2: that is to say, photocells installed on the
external gate side and which are active during the closing
phase only. When photocells 2 operate, the control unit
opens the gate immediately, without waiting for release.
City6 control unit supplies a 24VAC power supply to photocells
and it can perform a photocell operation test before starting the
gate opening phase. Photocell power terminals are protected by
an electronic fuse that stops current in case of overload.
• Connect power supply cables of photocells transmitter
between terminals P13 and P14 of the control unit.
• Connect power supply cables of photocells receiver between
terminals P12 and P14 of the control unit.
• Connect receiver output of photocells 1 between terminals
P4 and P5 of the control unit and receiver output of
photocells 2 between terminals P4 and P6 of the control
unit. Use outputs having normally closed contact.
The led displays above the P5 and P6 contacts respectively show
the entry status for type 1 and 2 photocells. If the led
display is on, the contact is shut, if it is off, the contact is open.
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 P13 and P14 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 during the
opening phase. When type 1 safety ribbons operate during
the gate opening phase, the control unit will close the gate
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).
• Type 2 (mobile): they are mounted to the gate 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 gate 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).
Both entries can handle the classic edge with a contact normally
shut and the conductive rubber edge with nominal
8.2 kOhm resistance.
Connect type 1 safety ribbons cables between terminals P7 and
P9 of the control unit.
Connect type 2 safety ribbons cables between terminals P8 and
P9 of the control unit.
In order to meet standard EN12978 requirements, edges must be
installed that are sensitive to conductive rubber; the sensitive
edges with a contact normally shut, must be fitted with a power
unit that constantly checks that everything is running smoothly. If
using control units suited to the test by power outage, connect
the power supply cables of the control unit between terminals
P13 and P14 of the City6. Otherwise, connect them between
terminals P12 and P14.
WARNING:
• When using more ribbons with N.C. contact, the inputs have
to be series connected.
• If using more conductive rubbers, the outputs have to be
cascade connected and only the last one has to be
terminated on the nominal resistance.
The led displays above the P7 and P8 contacts respectively
indicate the entry status for type 1 and 2 sensitive edge. See the
following table to establish the status according to the kind of
edge installed.

END OF STROKE

City6 control unit supports the end of stroke equipped with a
normally close switch that will be opened as soon as the gate
reaches its position desired.
Ends of strokes must be connected to the control unit terminal
board as follows:
• end of stroke in opening phase between terminal P10 and P9.
• end of stroke in closing phase between terminal P11 and P9.
The led displays above the P10 and P11 contacts respectively
show the end of strokes status. If the led display is on, the
contact is shut, if it is off, the contact is open.
