System Operation and Functions
All muting lamps that indicate state of muting function must be installed where workers can see
them from all the operating positions.
Use 2 independent input devices for muting input. A muting state may occur due to a single
failure of the muting sensor.
You must install F3SG-RA, muting sensor, and physical barrier, and configure time settings for
muting so that an operator should not enter hazardous zone.
The Dynamic Muting function can configure a new muting zone after muting is enabled based on
a result of workpiece height measurement for a certain period of time. The function must be used
after careful verification by a qualified person with sufficient training. Apply additional safety
measures if required.
 Using muting function
<Muting sensor>
The muting sensor is the sensor to trigger a signal to temporarily disable the safety functions of the
F3SG-R. You can use a photoelectric switch of through-beam type or reflective type proximity switch,
or limit switch. (Recommended: OMRON E3Z series, E2E series (3-wire type), D4N series)
Use a 3-wire type transistor output, which is the same as the output type of the F3SG-RA, or N.O. type
contact. Two-wire type sensor must not be used.
When the F3SG-RA is in PNP settings, use the muting sensor of the PNP transistor type.
When the F3SG-RA is in NPN settings, use the muting sensor of the NPN transistor type.
<Muting lamp>
You may need a muting lamp depending on your application or as a result of a risk assessment
analysis. Before determining the use of the muting lamp, check laws and regulations of the country or
region where the F3SG-RA is used and make sure of full compliance with them. For the muting lamp,
use a Lamp (F39-LP and F39-BTLP, sold separately) or a commercially available external indicator.
The external indicator can be connected to the auxiliary output.
For settings of the auxiliary output, see 2-11. Auxiliary Output.
For settings of the optional Lamp (F39-LP and F39-BTLP, sold separately), see 2-21. Lamp

Blinks during muting/override.
Blinks during a muting sequence error.
If the Dynamic Muting function is enabled, the indicator flashes while measuring
the workpiece height.
If the Dynamic Muting function is enabled, the indicator turns on after the new
muting zone is reflected.
