<Muting zone range>
You can specify a detection zone to be muted within the detection zone of the F3SG-SR.
2-13-2. Standard Muting Mode
2-13-2-1. Overview
The factory default setting is set to this mode.
Turning the muting inputs A and B ON with time difference enables the Muting state.
Start Conditions
If both of the following two conditions are satisfied, the MUTING state is enalbed.
1. No blocking object is found in the F3SG-SR's detection zone, and safety outputs are ON.
2. After the muting input A is turned ON*, the muting input B is turned ON* within the range between
the muting input time limit values T1min (0.1 s) and T1max (4 s).
*PNP setting: Vs-3V to Vs, NPN setting: 0 to 3V
The MUTING state can be enabled in up to 80 ms after the condition No.2 is satisfied.
When the condition No.1 is satisfied but the time requirement of the condition No.2 is not, a muting
sequence error occurs and the SEQ indicator on the receiver blinks. However, when there is a muting
sequence error, the F3SG-SR does not enter the MUTING state but it continues the normal operation
with the safety function enabled.
For muting error indication, see 8-1-3-3. Muting Sequence Error Indication.
The Muting error state can be released by any of following conditions:
1. Correct initial muting condition continues for 0.1 s or longer. *
2. Power cycle when the muting inputs A and B are in the OFF state.
* The correct initial muting condition is the state where the following two conditions are satisfied.
• Safety outputs of the F3SG-SR are turned ON.
• Muting input A and B are turned OFF.
Muting zone range Description
Full zone muted
(factory default setting)
Full area of the detection zone is muted.
This allows the safety function to be disabled in the full detection zone. This is a typical usage.
Partial zone muted A specified area in the detection zone configured by the SD Manager 3 is muted.
This can be used if you want to disable the safety function only in a specific area of the detection zone.
Setting the full detection zone for the muting zone allows the full zone to be muted.
Dynamic Muting This can be used by enabling the Dynamic Muting function.
The full detection zone is muted for a certain time period from the start of the muting, then a partial
zone is muted depending on the detected workpiece size.
