PHOTOCELLS - INSTRUCTIONS
•
The control unit powers the photocells at a nominal voltage
of 24 Vdc, with an electronic fuse that breaks the current in
the case of an overload.
•
If the transmitter power supply is connected to terminals
K8 and K9, the control unit can perform the photocell
operation test prior to starting gate opening.
•
The photocells on the interior side should be installed so as to
completely cover the gate opening area.
•
If several pairs of photocells are installed on the same side of
the gate, the receiver N.C. outputs should be connected in
series.
•
The photocells are not powered when the control unit is in
ENERGY SAVING mode.
4.4 - EXTERNAL PHOTOCELL CONNECTION
Photocells installed on the exterior side of the gate should be
connected as follows:
•
Connect the transmitter power supply to terminals
K8 (+Test) and K9 (-)
•
Connect the receiver power supply to terminals
K10 (+24 VDC) and K9 (-)
•
Connect the receiver N.C. output to terminals
J5 (PHOTO) and J4 (COM)
+
Photocells thus connected are active during closure.
In the case of tripping the photocell, the control unit immediately
TERY
re-opens the gate (without waiting for disengagement).
4.5 - INTERNAL PHOTOCELL CONNECTION
Photocells installed on the interior side of the gate should be
connected as follows:
•
Connect the transmitter power supply to terminals
K8 (+Test) and K9 (-)
•
Connect the receiver power supply to terminals
K10 (+24 VDC) and K9 (-)
•
Connect the receiver N.C. output to terminals
J6 (PHOTO) and J4 (COM)
+
Photocells thus connected are active both during opening and
during closing. In the case of the photocell tripping, the control
TERY
unit immediately stops the gate.
When the photocell is disengaged, the gate re-opens fully.

SAFETY RIBBONS - INSTRUCTIONS
•
If several edges, with normally closed contacts, are used, the
outputs should be connected in series.
•
If several conductive rubber edges are used, the outputs
should be connected in cascade, and only the final edge
should be terminated on the nominal resistance.
•
Active edges connected to the accessory power supply are
inactive when the control unit switches to ENERGY SAVING
mode.
•
To meet the requirements of EN12978, it is necessary to
install conductive rubber sensitive edges; contact normally
closed sensitive edges should have a control unit that
constantly verifies their correct operation. If control units
with the option to conduct testing by interrupting the power
are used, connect the control unit power cables between
terminals
K9 (-) and K8 (+Test) on the PD12.
Otherwise, connect them between terminals
K10 (+) and K9 (-).
Testing the edges should be activated by means of the
Co.tE
menu.
4.6 - CONNECTING SAFETY RIBBONS
The control unit considers two kinds of safety ribbons, depending
on the terminal to which they are connected:
•
Type 1 (fixed): they are mounted on walls or on other fixed
obstacles that are approached by the gate doors during the
opening phase. When type 1 safety ribbons operate during
the gate opening phase, the control unit will close the doors
for
3 seconds, then it stands still; when type 1 safety ribbons
operate during the gate closing phase, the control unit will
stand still immediately. The direction of the gate at next
command of START or PEDESTRIAN START depends upon the
parameter STOP (it inverts or continues the motion).
M2
If the input STOP is disabled, the command makes the motion
continue in the same direction.
24Vdc
•
Type 2 (mobile): they are mounted to the door ends.
When type 2 safety ribbons operate during the gate opening
phase, the control unit will stand still immediately; when type
2 safety ribbons operate during the gate closing, the control
unit will open the doors for 3 seconds, then it will stand still.
The direction of the gate at next command of START or
PEDESTRIAN START depends upon the parameter STOP (it
inverts or continues the motion). If the input STOP is disabled,
the command makes the motion continue in the same
direction.
M1
Both the input can manage the classic safety edge with n.c.
24Vdc
contact and the conductive rubber safety edge with 8,2 kohm
nominal resistance.
Connect type 1 safety ribbons cables between terminals
24 Vdc
J7 (EDGE1) and J9 (COM) of the control unit.
Connect type 2 safety ribbons cables between terminals
J8 (EDGE2) and J9 (COM) of the control unit.
