5.3 - INGRESSI DI ATTIVAZIONE
The control unit KB24 has two activation inputs available, whose
functions depend on the programmed mode of operation (See
Strt
voice
on the programming menu):
Standard mode: first input (START1) controls the opening, the
closing and the arrest depending on the programming mode set.
The second input (START2) causes the opening of the barrier
MASTER when it is activated the synchronized operation of two
barriers.
Open/Close and Dead Man mode: an input command on
push-button START1 always commands the opening and an input
command on push-button START2 always commands the closing.
• In the Open/Close mode the command is of impulsive type, that
is, an impulse causes the total opening or closing of the barrier.
• In the Dead Man mode, the command is of the monostable type,
that is the barrier opens or closes as long as the contact is closed
and arrests immediately if the contact becomes open.
Input/Output Mode: this function must be set when a traffic light is
connected for an alternating one-way.
The command is impulsive, that is, a pulse causes the bar to open
completely; if the command arrives on the input START1 the green
switches on in the entry direction, if it arrives on the input START2 the
green switches on in the exit direction.
Clock mode: it is analogous to the standard mode, but the barrier
remains opened as long as the contact remains closed on the
input START1; when the contact comes opened begins the pause
countdown, which upon expiring the barrier recloses.
This function allows programming throughout the day the opening
hour cycles of the barrier, using for this an external timer.
It is indispensable to enable automatic reclosing.
m
ATTENTION: in all modes, the input commands must be
connected to devices with normally opened contacts.
Connect the cables of the device that commands the START1
input between terminals J1 and J4 of the control unit.
Connect the cables of the device that commands the START2
input between terminals J2 and J4 of the control unit.
The function associated to the START1 input command can also be
activated by pressing push-button
menu, or by means of a remote control command memorized on
channel 1 (see the instructions of receiver MR).
The function associated to the START2 input command can also be
activated by pressing push-button
menu, or by means of a remote control command memorized on
channel 2 (see the instructions of receiver MR).

5.4 - STOP
For greater safety it is possible to install a push-button that when
pressed causes immediate stop of the barrier. The switch must have
a normally closed contact that opens in case of set in action.
If the stop switch is set in action while the barrier is opened, the
automatic reclosing function becomes disabled; in order to reclose
the barrier it is necessary to give a start command (if the start function
in pause is disabled, it becomes temporarily reenabled in order to
allow the lock release of the barrier).
Connect the stop switch cables between cables J3 and J4 of
the control unit.
5.5 - PHOTOCELLS
Photocells can be activated in two ways:
1. Only during closing: in which case the passage in front of the
beam would cause the immediate reopening.
2. During the opening and closing: in which case the interruption of
the beam causes the immediate arrest. When the beam is freed,
a complete reopening of the barrier occurs.
m
ATTENTION: install the photocells to cover the entire
opening / closing surface of the boom.
The control unit KB24 provides 24VDC power supply for the
photocells and it can test their performance before beginning the
opening of the boom. An electronic fuse that shuts down the power
supply in case of an overload protects the power supply terminals of
the photocells.
• Connect the feeder cables of the photocells transmitter between
terminals Z3 (+) and Z2 (-) of the control unit.
• Connect the feeder cables of the photocells receiver between
terminals Z1 (+) and Z2 (-) of the control unit.
• Connect the Common and the N.C. (Normally Closed) contact of
the photocells receiver on terminals J6 (PHOTO) and J9 (COM)
of the control unit. Use the exits with normally closed contact.
m
ATTENTION:
• if more photocells copies of the same kind are to be installed,
their outputs must be connected in series.
• if reflection photocells are to be installed, the power supply must
be connected to terminals Z3 (+) and Z2 (-) of the control unit to
carry out the functional test.
• The photocells are not powered when the control unit switches to
ENERGY SAVING mode
