4-3 Override function
Muting and Override function can disable the safety functions of a machine. The
proper installation, checkout and operation of a machine and muting system in
accordance with all applicable laws and standards, is critical to the safe operation
of the machine.
Failure to comply with these instructions may result in severe injury to personnel.
The muting lamp for indication "active muting" or "active override" must be
positioned in a place where it can be seen from any operative point.
The TEST and RESET buttons must be positioned in such a way
- that the operator can see the protected area when he carries out reset, test, or
override operations.
- that it can not be activated from inside the hazardous area.
4-3-1 Override operations
(1) Switch off the F3SP.
(2) Switch on the F3SP
(3) During the countdown displayed, press together the TEST and RESET
buttons and keep pressing. (Do not press the buttons before the
countdown. Otherwise a failure occurs, because a self-test is carried out to
check that the buttons are not locked).

character '≡' which indicates override active. The muting lamp blinks to
signal the light curtain is not active.
(5) The minimum duration of the override function amounts to 60 seconds. If
the buttons are released before this time has elapsed, the override
