6.3 - ACTIVATION INPUTS

CITY2+ control unit is equipped with two activation inputs
(START and START P.), whose operation depends on the
programmed operation modes (see Strtitem of programming
menu)
Standard mode
START = START (a command will cause the complete
opening of the gate)
START P. = PEDESTRIAN START (a command will cause the
partial opening of the gate)
Open/Close command
START = OPENING (always controls the gate opening)
START P. = CLOSING (always controls the gate closing)
This is an impulse command, that is to say that an impulse
will cause the complete gate opening or closing.
Dead man operation
START = OPENING (always controls the gate opening)
START P. = CLOSING (always controls the gate closing)
This is a monostable command, that is to say, the gate will
be opened or closed as long as the contact is closed and it
will immediately stop as the contact is open
Timer mode
This function allows programming the gate opening time during
the day, by making use of an external timer.
START = START (a command will cause the complete opening of
the gate)
START P. = PEDESTRIAN START (a command will cause the partial
opening of the gate)
The gate stays open (completely or partially) while the contact is
closed on input; as soon as the contact is open the pause time
count down will start, after which the gate will be closed again.
m
ATTENTION: Automatic closing must be enabled.
NOTE: in all modes, inputs must be connected to devices
having normally open contacts.
Connect cables of device controlling the first input between
terminals L3 (START) and L6 (COM) of the control unit.
Connect cables of device controlling the second input between
terminals L4 (START P.) and L6 (COM) of the control unit.
The first input function can also be activated by pressing UP key
outside the programming menu or by means of a remote control
stored on channel 1 (see relevant instructions of MR receiver).
The second input function can also be activated by pressing
DOWN key outside the programming menu or by means of a
remote control stored on channel 2.

6.4 - 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 L5 (STOP) and
L6 (COM) 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 MR
receiver).
The command STOP from remote is operative also if the input
STOP of the terminal board is disabled.

6.5 - PHOTOCELLS

The control unit considers two kinds of photocells, depending on
the terminal to which they are connected:
Photocell 1
Photocells installed on the gate inner side, which are active both
during the opening and the closing phase. When photocells 1
operate, the control unit stops the gate; as soon as the photocell
beam is free, the control unit will open the gate completely.
m
WARNING: Type 1 photocells must be installed so that
they completely cover the opening area of the gate.
Photocell 2
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.
CITY2+ control unit supplies a 24Vdc 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.
m
PLEASE NOTE: it is recommended that the cable ducts
used for the motor cables NOT BE USED for the cables
connecting the photocells.
• Connect power supply cables of photocells transmitter
between terminals K7 (-) and K8 (+Test) of the control unit.
• Connect power supply cables of photocells receiver between
terminals K6 (+) and K7 (-) of the control unit.
• Connect receiver output of photocells 1 between terminals
L7 (PHOTO1) and L11 (COM) of the control unit and receiver
output of photocells 2 between terminals L8 (PHOTO2) and
L11 (COM) of the control unit.
Use outputs having normally closed contact.
m
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 K7 (-) and K8 (+Test) of the control
unit to carry out the operation test.
