System Operation and Functions
2-13. Override
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-RA, 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-RA. However, the override function will mute the safety outputs of the F3SG-RA 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.
Receiver's top-beam-state indicator and bottom-beam-state indicator blink during override.
The Override is not available for the F3SG-RE.
The muting and override functions disable the safety function of the device. You must ensure
safety using other method when these functions are operating.
Install the switch that uses hold-to-run device such as a spring-return key switch. Install the
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.
Override time must be properly configured for its application by a sufficiently trained and qualified
person.
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.
