2-13. Muting
The Muting and Override functions disable the safety functions of the device. Especially
setting the Muting Time Limit parameter to infinite may cause the safety functions to be
disabled for a long time. Install the F3SG-SR, muting sensor and physical barrier and
configure time settings for Muting and Override so that an operator should not enter
hazardous zone when the Muting and Override are active.
Install muting sensors so that they can distinguish between the object that is being
allowed to pass through the detection zone and a person. If the Muting function is
activated by the detection of a person, the machine may not stop operating, resulting in
serious injury.
Muting lamps that indicate the state of the Muting and Override functions must be
installed where they are clearly visible to workers from all the operating positions.
Use two independent input devices for muting inputs. Failure to do so may cause the
MUTING state due to a single muting sensor's failure.
2-13-1. Overview
Muting function temporarily disables safety function of the F3SG-SR, keeping safety outputs ON even
if beams are blocked. This makes it possible to install safety light curtains for AGV passage, enabling
both safety and productivity. When muting is active, the area beam indicator (ABI) *1 or the TOP/BTM
indicator blinks to notify people around the sensor that the safety functions are disabled.
The following three operation modes are available for the Muting function.
1. Standard Muting mode (factory default setting)
2. Exit-Only Muting mode
3. Position Detection Muting mode
*1 F3SG-SRA is applicable.
*2 F3SG-SRB is applicable.
Refer to 2-1. Combination of Functions for more information on the use in conjunction with other functions.
The following settings are available for a beam range to be muted.
• Full zone muted (factory default setting)
• Partial zone muted
