System Operation and Functions
2-14-3. Override upon Startup
You can enable the OVERRIDE state by entering a special sequence when the power is turned on.
This function is dedicated to Exit-Only Muting mode.
Under the Standard Muting mode or the Position Detection Muting mode, a workpiece can be ejected using the Override
function under the normal operation as any of muting inputs always turns on even if the power is restarted while muting
failed.

Override start conditions
When all of the following conditions are satisfied, the OVERRIDE state is enabled. The OVERRIDE
state can be achieved even when there is a muting error.
1. The F3SG-SR is blocked
2. An input signal of a special sequence is entered three times to the RESET line within 3 to 6 s after
power-on. The signal must be entered within a range from 0.2 s to the override input time limit T1
(initial value: 1 s). (See the timing chart below.)

Override end conditions
When any one of the following conditions is satisfied, the OVERRIDE state is released.
1. A period of 600 s (configurable) passes in the OVERRIDE state
2. The F3SG-SR is unblocked
3. 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.
