7-2. Maintenance Checklists
Perform daily and 6-month inspections for all F3SG-SR. When using the F3SG-SR in cascade
connection, perform inspections for every connected F3SG-SR. Otherwise, the system may fail
to work properly, resulting in serious injury.
Do not try to disassemble, repair, or modify the product. Doing so may cause the safety functions
to stop working properly.
To ensure safety, keep a record of the inspection results.
When the user is a different person from those who installed or designed the system, he/she must be properly
trained for maintenance.

7-2-1-1. Inspection at Startup and When Changing Operators
There is no approach route other than through the detection zone of the F3SG-SR.
Part of the operator's body always remains in the detection zone of the F3SG-SR 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 front window or Spatter Protection Cover (F39-HSG, sold
separately) of the F3SG-SR.
When PNP is selected, the OSSD indicator turns red when the TEST line is short-circuited to 9 V to Vs.
When NPN is selected, the OSSD indicator turns red when the TEST line is short-circuited to 0 to 3 V.
When the 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:
When the F3SG-SR is turned ON and the F3SG-SR is unblocked, the OSSD indicator remains red.
The reset input turns the OSSD indicator to green.
When the Restart Interlock function is used:
When the OSSD indicator is green and the F3SG-SR is blocked and then returned to unblocked
state, the OSSD indicator remains red. The reset input turns the OSSD indicator to green.
When the power of the F3SG-SR is turned ON while nothing is in the detection zone, it must operate
as follows:
If Start Interlock is not used: The OSSD indicator turns green within 3 s after the F3SG-SR is turned ON.
If Start Interlock is used: The SEQ indicator turns yellow and the OSSD indicator turns red within 3 s
after the F3SG-SR is turned ON.
Nothing should exist in the detection zone and the OSSD indicator must turn ON (red or green) at
