System Operation and Functions
2-14-2. Override at Normal Operation
You can enable the Override function under the normal operation.
 Override start conditions
If all of the following conditions are satisfied, the OVERRIDE state is enabled. The OVERRIDE state
can be enabled even when there is a muting error.
1. Either muting input A or B is in the ON state. (One or more muting sensors are turned ON by a
workpiece)
This does not apply to Exit-Only Muting mode.
2. The F3SG-SR is blocked and the safety outputs are in the OFF state.
3. An input signal of a special sequence is entered three times to the RESET line when the conditions
No. 1 and 2 above are satisfied. The signal must be entered within a range from 0.1 s to the override
input time limit T1 (1 s). (See the timing chart below.)
The F3SG-SR does not enter the OVERRIDE state when the sensor is in LOCKOUT state.
 Override end conditions
When any of the following conditions is satisfied, the OVERRIDE state is released.
1. A period of 600 s (configurable) passes in the OVERRIDE state.
2. All muting sensors are turned OFF.
3. The F3SG-SR is unblocked (during exit-only muting mode).
4. The following signal to cancel the OVERRIDE state is entered:
• When the external device monitoring function is enabled, the RESET line is turned ON. (PNP:
Connected to Vs-3 V~Vs; NPN: Connected to 0 V~3 V)
• When the external device monitoring function is disabled, the RESET line is turned OFF.
The OVERRIDE state can be also released when the F3SG-SR enters the LOCKOUT state.
