System Operation and Functions

Using muting function
<Muting sensor>
The muting sensor is the sensor to trigger a signal to temporarily disable the safety functions of the
F3SG-SR. You can use a photoelectric sensor 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-SR, or NO type
contact. Two-wire type sensor must not be used.
The Intelligent Tap is necessary when using the Muting with the F3SG-SR in the Wiring
Synchronization.
The Intelligent Tap cannot be used when using the Muting with the F3SG-SR in the Optical
Synchronization.
When the F3SG-SR is in PNP settings, use the muting sensor of the PNP transistor type.
When the F3SG-SR 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-SR is used and make sure of full compliance with them. For the muting lamp,
use a commercially available external indicator.
The external indicator can be connected to the auxiliary output.
For settings of the auxiliary output, see 2-12. Auxiliary Output.
<LED indicator statuses>
*1 F3SG-SRA is applicable.
*2 F3SG-SRB is applicable.
For muting error indication, see 8-1-3-3. Muting Sequence Error Indication.
For dynamic muting, see 2-13-5. Dynamic Muting.
For the use in conjunction with other functions, see 2-1. Combination of Functions.
Area beam indicator (ABI) *1 Blinks under the MUTING or OVERRIDE state.
TOP/BTM indicator *2
SEQ indicator Blinks during a muting sequence error.
CFG indicator If the Dynamic Muting function is enabled, the indicator blinks while measuring the
workpiece height.
If the Dynamic Muting function is enabled, the indicator turns on after the new
muting zone is determined.
