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, 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 that activates the Override and that uses hold-to-run device, such as spring
return key switch, 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.
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, 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. However, the Override function will mute the safety outputs of the
F3SG-SR so that the conveyor only can be restarted to move the workpiece out of the muting sensors
and detection zone.
The Override function can be enabled for up to 600 s.
The Area Beam Indicator (ABI) *1 or TOP/BTM Indicator *2 blinks during the Override state.
*1 F3SG-SRA is applicable.
*2 F3SG-SRB is applicable.
