Override; Starting The Override Function - Omron F3SP-U4P-TGR User Manual

F3SP-U4P-TGR
7.3

OVERRIDE.

This function makes it possible to force a muting condition, if necessary by
starting the machine despite one or both safety light curtains having been
interrupted by the object. Thus enabling removal of the material from the
protected area, when it has been stuck in the beam of the safety light
curtains due to a failure.
Suppose that a pallet has stopped before the light curtains; the conveyor
belt cannot be started again because the control unit - after having
detected one or more interrupted light curtains- 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 control unit.
• Make sure that the TEST and RESET buttons are connected. (N.C.
for the TEST button, N.O. for the RESET button).
• Switch on the control unit.
• 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 light curtain disconnection.
• The maximum duration of the override function amounts to 60
seconds after that the light curtain is connected again even if the
buttons are pressed. If the buttons are released before this time has
elapsed, the override function will be immediately stopped.
