Electric Lock; Photocell; Safety Ribbons; End Of Stroke - V2 SPA CITY4 Mode D'emploi

ELECTRIC 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 P13 and P14 of the control unit.

PHOTOCELL

City4 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.
The photocells are active only during the closing phase and, if
required, with standstill gate. In case intervention, the control
unit immediately opens the gate, not waiting for the release.
• Connect power supply cables of photocells transmitter
between terminals P11 and P12 of the control unit.
• Connect power supply cables of photocells receiver between
terminals P10 and P11 of the control unit.
• Connect receiver output between terminals P6 and P9 of the
control unit. Use outputs having normally closed contact.
WARNING:
• if several couples of photocells are mounted, their outputs
must be connected in series.
• In case of reflection photocells, power supply must be
connected to terminals P11 and P12 of the control unit to
carry out the operation test.

SAFETY RIBBONS

The control unit City4 is equipped with a specially provided input
to control safety ribbons; the intervention of the edge reverses
the motion for 3 seconds either during the opening or the
closing phase. This input can control either the classic edge with
N.C. contact, or the conductive rubber ones with nominal
resistance 8,2 kohm.
Connect the cables of the safety ribbons between terminals P5
and P9 of the control unit.
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.
ADDITIONAL PHOTOCELLS
The input dedicated to the safety edges can be used, as an
alternative, to manage additional photocells, active during
opening and closing.
If you choose to use the edge input to control the photocells,
proceed as follows:
• Connect the output of the receivers of the photocells
between the terminals P5 and P9 of the control unit
• Connect the power supply as the standard photocells
• In the Cost programming menu, select the entry Fot.i
NOTE: to enable the functional test on these devices you need
to enable the safety edge test.

END OF STROKE

City4 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 opening phase between terminal P7 and P9.
• end of stroke in closing phase between terminal P8 and P9.

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 P3 and P4 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).
