SAFETY RIBBONS
The control unit makes it possible to use standard edges with
normally closed contacts or wireless edges (see the instructions
provided with the device).
The control unit considers two kinds of safety ribbons,
depending on the terminal to which they are connected:
•
Type 1 safety ribbons:
they are installed in the locations
that become dangerous during the opening phase.
When type 1 safety ribbons operate during the gate opening
phase, the control unit will close the gate 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. Next Start or Pedestrian Start command will
restore the gate motion towards the same interrupted
direction.
•
Type 2 safety ribbons:
they are installed in the locations
that become dangerous during the closing phase.
When type 2 safety ribbons operate during the gate closing,
the control unit will open the gate for 3 seconds, then it will
stand still; when type 2 safety ribbons operate during the
gate opening phase, the control unit will stand still
immediately.
Next Start or Pedestrian Start command will restore the gate
motion towards the same interrupted direction.
PLEASE NOTE: WIRELESS edges (type 2) are
inactive during opening
Connect type 1 safety ribbons cables between terminals
7
and
9
of the control unit.
Connect type 2 safety ribbons cables between terminals
8
and
9
of the control unit.
WARNING: Make use of safety ribbons having
outputs with normally close contact. Outputs of same kind
safety ribbons must be connected in series.
END OF STROKE
Limit sensors come connected already to terminals
22
,
23
,
24
and
25
by means of a polarized connector.
CAUTION: Never reverse the connector.
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 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
3
and
4
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
MR1 receiver).
ACTIVATION INPUTS
Pd8
control unit is equipped with two activation inputs, whose
operation depends on the programmed operation modes (see
Strt
item of programming menu):
•
Standard mode:
a command being on the first input will
cause the complete opening of the gate (start); a command
being on the second input will cause the partial opening of
the gate (pedestrian start).
•
Open/Close command and manned operation:
a command on the first input always controls the gate
opening, while a command on the second input always
controls the gate closing.
In Open/Close mode, there is an impulse command, that is
to say that an impulse will cause the complete gate opening
or closing.
In manned operation, there is a monostable command, that
is to say, the gate will be opened or closed as long as the
contact is closed and it will immediately stop as the contact
is open.
