Checklists
Inspection at Startup and When Changing Operators
There is no approach route other than through the detection zone of the F3SJ.
Part of the operator's body always remains in the detection zone of the F3SJ when working around
the machine's hazardous part.
The actual safety distance is equal to or greater than the calculated value.
There must be no dirt on or damage to the optical surface, spatter protection cover (F39-HJ, sold
separately), or environment-resistant casing (F39-EJ, sold separately) of the F3SJ.
OFF output indicator must be turned ON when test input line is short-circuited to 9 to 24V.
When muting function is used, muting lamp must not be clear due to dirt or degradation.
The test rod is not deformed.
When the start interlock function is used:
After the F3SJ is turned ON, the OFF output indicator must remain turned ON, even if the F3SJ is
receiving light. The reset switch input must turn ON the ON output indicator.
When the restart interlock function is used:
While the ON output indicator is ON, the OFF output indicator must remain turned ON, even when
the F3SJ is blocked and then receives light again. The reset switch input must turn ON the ON output
indicator.
When the power of the F3SJ is turned ON while nothing is in the detection zone, it must operate as
follows:
If start interlock is not used: Power indicator and ON output indicator must turn ON within 2 seconds
(2.2 seconds in case of series connection).
If start interlock is used: Power indicator and OFF output indicator must turn ON within 2 seconds (2.2
seconds in case of series connection).
Nothing should exist in the detection zone and 5 incident light level indicators must turn ON at power on.
