5.6 - SAFETY RIBBONS
They can be installed located on the anti-shock rubber bumper strip,
which normally comes provided with the boom kit.
In case of intervention during the closing, reopening and disabling of
the automatic closing occurs.
The control unit is able to carry out either the classic safety ribbons
with normally closed contact, or conductive rubber safety ribbons
with 8,2 kohm nominal resistance.
Connect the cables between terminals J8 and J9 of the control unit.
m
ATTENTION: In order to meet the requirements of the
EN12978 rules, it is necessary to install safety ribbons controlled by a
control unit continuously checking the proper working.
If using control units suited to the test by power outage, connect the
power supply cables of the control unit between terminals Z3 (+) and
Z2 (-) of the control unit.
Otherwise, connect them between terminals Z1 (+) and Z2 (-).
m
ATTENTION:
• If more safety ribbons with normally closed contact are used, their
outputs must be connected in series.
• If more safety ribbons with pressure conductive rubber are used,
their outputs must be connected in cascade style and only the
last one must be ended on the nominal resistance.
• The active edges, connected to the accessory power supply, are
not active when the control unit switches to ENERGY SAVING
mode
5.7 - COURTESY LIGHT
The COURTESY LIGHT output consists of a simple N.O. contact
(Normally Open Circuit) and does not provide any power supply.
Thanks to the COURTESY LIGHT output, the control unit KB24
allows the connection of a utility light (a courtesy light or a garden
light, for example), which is programmed automatically, or by
arming channel 4 of the MR receiver.
The COURTESY LIGHT output consists of a simple N.O. contact
and does not provide any power supply. The maximum output of the
contact is of 230V - 5A
Connect the cables to terminals B1 and B2.
5.8 - LOW VOLTAGE LIGHT OUTPUT
The control unit has a 24 VDC output that allows connection of a
maximum load of 12 W.
This output can be used to connect a warning light, indicating the
status of the barrier, or for a low voltage flashing light.
Connect the low voltage signal light or flashing light wires to
terminals Z5 (+) and Z4 (-).
m
CAUTION: Pay attention to the polarity of the connected
device if necessary.
5.9 - ANTENNA
We suggest to use the external aerial (model: ANS433) in order to
guarantee the maximal range.
Connect the antenna hot pole to terminal A2 of the control unit and
the braiding to terminal A1.
5.10 - HOLDING MAGNET
The control unit KB24 is equipped with an output for feeding an
holding magnet. Through a dedicated menu it is possible to regulate
the output voltage up to a maximum value of 24Vdc.
The power supply to the holding magnet is interrupted at the
beginning of every opening (with adjustable anticipation from the
menu) and restored at the end of the closing (with adjustable delay
from the menu).
Connect the power supply to the holding magnet between
terminals Z5 (+) and Z6 (-).
PLEASE NOTE: The locking electromagnet is connected to the
accessory power supply. Hence, it is essential to deactivate
the energy saving function to use it.
5.11 - MAGNETIC COIL OR PRESENCE
SENSOR
NOTE: if the ENERGY SAVING function is enabled, this function is
not available
The ST.NC input can be used for the connection of a presence
detection device for vehicles (magnetic coil) or people (presence
sensor) in the barrier area, using opening of a normally closed
contact.
When presence is detected, the bar is raised and it is not possible to
lower it until the area is freed.
When the sensor indicates the area is free again, the count starts for
automatic closure time, if enabled.
The same input can be used for the fire-prevention sensor. In this
case, the bar is not lowered automatically when contact is reset.
Connect the cables to terminals J5 and J9.
