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.
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).
ACTIVATION INPUTS
City4
control unit is equipped with two activation inputs, whose
operation depends on the programmed operation modes (see
Strt
item of programming menu):
•
Standard mode:
a command being on the first input will
cause the complete opening of both leaves (start); a
command being on the second input will cause the partial
opening of leaf 1 only (pedestrian start).
•
Open/Close command and manned operation:
a command
on the first input always controls the gate opening, while a
command on the second input always controls the gate closing.
In Open/Close mode, there is an impulse command, that is
to say that an impulse will cause the complete gate opening
or closing.
In manned operation, there 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:
it is similar to the standard mode but 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. This function allows programming the gate
opening time during the day, by making use of an external
timer. Automatic closing must be enabled.
In all modes, inputs must be connected to devices having
normally open contacts.
Connect cables of device controlling the first input between
terminals
P1
and
P4
of the control unit.
Connect cables of device controlling the second input between
terminals
P2
and
P4
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 MR1
receiver).
