2-12-1.Standard Muting Mode - Omron F3SG series User Manual

<Muting range>
You can specify a detection zone to be muted within the detection zone of the F3SG-RA.
Muting Range
Full Zone Muted State Full area of the detection zone is muted.
(factory default This disables the full detection zone and is used typically.
setting)
Partial Zone Muted A specified area in the detection zone configured by the Configuration Tool is muted.
State This can be used if you want to disable only a specific area of the detection zone.
Specifying the full zone results in the Full Zone Setting State.
Dynamic Muting This can be used by enabling the Dynamic Muting function.
The full detection zone is disabled for a certain time period from the start of the muting, then a partial
zone is muted depending on the detected workpiece size.
2-12-1. Standard Muting Mode
The factory default setting is set to this mode.
Turning muting inputs A and B ON with time difference enables muting state.
 Start Conditions
If both of the following two conditions are satisfied, the muting state is enalbed.
1. No interrupting object is found in the F3SG-RA's detection zone, and safety outputs are ON.
2. After muting input A is turned ON*, 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
Muting state can be enabled in up to 80ms 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 Sequence error indicator on the receiver blinks. However, when there is
a muting sequence error, the F3SG-RA does not enter the Muting state but it continues the normal
operation with the safety function enabled.
For muting error indication, see 7-1-2-3. Muting Sequence Error Indication.
Muting error can be released by any of following conditions:
1. Correct muting initial condition continues for 0.1 s or longer. *
2. Power cycle when 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-RA are turned ON.
• Muting input A and B are turned OFF.
 End conditions
If either of the following conditions is satisfied, the muting state is released.
• Muting input A or B turns OFF for the maximum allowable muting signal interruption of T3 (at least
0.1 s: configurable) or longer.
• The duration of the muting state exceeds the muting time limit of T2 (at least 60 s: configurable).
Muting state is also released when the F3SG-RA enters the Lockout state.
