Stop; Connecting Photocells; Connecting Safety Ribbons - V2 ALFARISS Mode D'emploi

4.3 - 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 (NC) 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 J3 (STOP) and
J4 (COM) 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
MRx receiver).
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
E3 (+) and E2 (-), 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 - CONNECTING PHOTOCELLS

The control unit considers two kinds of photocells, depending on
the terminal to which they are connected:
• Photocell 1: that is to say, photocells installed on the gate
inner side, which are active both during the opening and the
closing phase. When photocells 1 operate, the control unit
stops the gate; as soon as the photocell beam is free, the
control unit will open the gate completely.
• Photocell 2: that is to say, photocells installed on the
external gate side and which are active during the closing
phase only. When photocells 2 operate, the control unit
opens the gate immediately, without waiting for release.
• Connect power supply cables of photocells transmitter
between terminals E3 (+) and E2 (-) of the control unit.
• Connect power supply cables of photocells receiver
between terminals E1 (+) and E2 (-) of the control unit.
• Connect receiver output of photocells 1 between terminals
J5 (PHOTO1) and J9 (COM) of the control unit and receiver
output of photocells 2 between terminals J6 (PHOTO2) and
J9 (COM) of the control unit.
Use outputs having normally closed contact.
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 E3 (+) and
E2 (-) on the PD13.
Otherwise, connect them between terminals
E1 (+) and E2 (-).
Testing the edges should be activated by means of the
Co.tE
menu.

4.5 - 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).
If the input STOP is disabled, the command makes the motion
continue in the same direction.
• 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.
Both the input can manage the classic safety edge with n.c.
contact and the conductive rubber safety edge with 8,2 kohm
nominal resistance.
Connect type 1 safety ribbons cables between terminals
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.
