Omron F3SJ-A series User Manual page 125

A secondary sensor farthest from its power supply has either of the followings:
- Cap
- Key cap for muting
- Muting lamp (set of lamp and cable)
Neither connector, cap, or bracket must be loose.
Auxiliary outputs 1, and external indicator outputs 1 and 2 must not be used as safety output.
Power supply's 0V must be grounded.
Wiring must not be bent, cracked, nor damaged.
Operation Check While the Machine Is Stopped
The test rod is not deformed.
Depending on the unit's model, detection capability may vary. Use a test rod with an appropriate
diameter for inspection.
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.
To check detection, 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 9 to 24V.
When the external device monitoring function is used:
When the F3SJ 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 is turned OFF.
The actual response time of the whole machine is equal to or less than the calculated value.
