F3SJ-A-TS
Quick Installation Manual
Depending on the unit's model and settings of floating blanking function, detection capability may vary.
Use a test rod with an appropriate diameter for inspection. The model name of test rod is as follows.
□
The sensor can detect a test rod wherever it is in the detection zone. In other words, when a test rod is
inserted into the detection zone, all 5 incident light level indicators turn OFF, and the OFF-state indicator
turns ON. When fixed blanking function is used, you must ensure that all blanked zones in the detection
zone are covered by construction and that there should be no zone that cannot detect the test rod in the
detection zone. To check detection, insert the test rod vertically to detection area and move the test rod
as shown in the diagram below.
□
When the external test function is used:
The OFF-state indicator turns ON when the test input line is short-circuited to 9V to Vs.
□
When the external device monitoring function is used:
When the F3SJ-A-TS is blocked and the external device monitoring input terminal is open, it enters a
lockout state.
-Checking that Hazardous Parts Stop While the Machine Operates
□
The hazardous parts stop immediately when a test rod is inserted into the detection zone at 3 positions:
"directly in front of the emitter", "directly in front of the receiver", and "between the emitter and receiver".
(Use the appropriate test rod.)
□
The hazardous parts remain stopped as long as the test rod is in the detection zone.
□
The hazardous parts stop when the power of the F3SJ-A-TS is turned OFF.
□
The actual response time of the whole machine is equal to or less than the calculated value.
Maintenance Checklists
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.

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 sepa-
rately), 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 9V to Vs.
□
When muting function is used, muting lamp must not be clear due to dirt or degradation.
□
The test rod is not deformed.
□
When the power of the F3SJ is turned ON while nothing is in the detection zone, power indicator and ON
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.
□
The test rod is detected when it is moved around in the detection zone as shown in the diagram of Pre-
Operation Checklists.
