Override; Starting The Override Function - Omron F3SP-U3P-TGR User Manual

F3SP-U3P-TGR
•
The TEST and START pushbuttons must be positioned in such a
way that the operator can see the protected area when he carries
out start, test or override operations.
•
The F39-A11 muting lamp must be positioned in a place where it
can be seen from any operative point.
•
If the muting sensors are installed very near the protection
photocells, it is necessary to install the sensor receivers on the
photocell sender side to avoid interference.
•
The system is anyway protected from possible failures due to the
cable damage; it is necessary to prepare the wiring of all
connections so as to avoid damage to the connection cables.
•
The control unit must be located in a cabinet with protection
degree of at least IP54.

OVERRIDE.

This function makes it possible to force a muting condition, if it is
necessary to start the machine despite one or more rays have been
interrupted by the material. The aim is that of removing from the protected
area the material which has possibly gathered before the photocells for
instance because of a failure of the machine cycle.
Let's suppose that a pallet has stopped before one or more used optical
devices; the conveyor belt cannot be started again because the control
unit - after having detected one or more interrupted rays - will not close the
safety outputs, thus making it impossible to free the controlled area.
By starting the override function, it will be possible to carry out this
operation.

STARTING THE OVERRIDE FUNCTION.

• Switch off the device.
• Make sure that the TEST e START buttons are connected. (N.C. for
the TEST button, N.O. for the START button).
• Switch on the device.
• Within 10 seconds, press together the test and reset buttons and
keep pressing. (At each switching on operation, a test is carried out
to check that the buttons are not locked).
• The override function has been activated. The muting lamp blinks to
signal the barrier disconnection.
• The maximum duration of the override function amounts to 60
seconds after that the unit is connected again even if the buttons
are pressed. Obviously, if the buttons are released before this time
has elapsed, the override function will be immediately stopped.
