2-14. Override
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/PG, 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.
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.
Install the switch to activate the Override function in a location that provides a clear view of the
entire hazardous zone and where it cannot be activated from within the hazardous zone. Make
sure that nobody is in the hazardous zone before activating the Override function.
Make sure to connect an override cancel switch to the RESET line when using the Override
function. Otherwise, the OVERRIDE state may not be released by the override cancel switch,
resulting in serious injury.
If a meeting error occurred while a workpiece blocks F3SG, you can use either of the following
ways to remove the workpiece:
1) manually (with additional safety measures), or
2) Override function (override under normal operation or on startup)
You must use either of the above ways. You MUST NOT use both ways.
Using both ways may activate the Override function at an unintended timing for a worker.
2-14-1. Overview
The Override function turns the safety outputs ON when the muting start condition is not satisfied. If a
workpiece stops while passing through the F3SG-SR/PG, as shown below, causing a muting error, the
normal state cannot be recovered unless the workpiece is removed from the muting sensors and the
detection field of the F3SG-SR/PG. However, the Override function will mute the safety outputs of the
