9.4 - 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 PD21 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 K9 and K10 of the control unit.
• Connect the feeder cables of the photocells receiver between
terminals K8 and K9 of the control unit.
• Connect the Common and the N.C. (Normally Closed) contact
of the photocells receiver on terminals K5 (PHOTO) and
K7 (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 K9 and K10 of the control
unit to carry out the functional test.
On the cabinet sides there are holes for installing SENSIVA
photocells:

9.5 - 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 K6 and K7 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
K9 and K10 of the control unit. Otherwise, connect them
between terminals K8 and K9.
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.

9.6 - COURTESY LIGHT

This output can be used for the connection of the cover with
integrated flashing light (accessory) or for an external courtesy
light. The output is automatically activated when the barrier is
functioning; it is manually activated when transmitting a code
stored on channel 4 on the receiver MR.
The operating logic depends on the settings of the parameter
LUCi
The courtesy light terminals can be used as an alternative for a
230V flashing light with integrated intermittence.
m
ATTENTION: 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 B3 and B4.

9.7 - EXTERNAL FLASHING LIGHT

PD21 control unit provides for a 230V - 40W external flashing
light equipped with intermittence inside.
Connect the cables to terminals B1 and B2.
m
WARNING: DO NOT use this output to connect the
cover with integrated flashing (optional)
