System Operation and Functions
When Position Detection Muting and External Device Monitoring Disabled
2-13-2. 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. F3SG-RA is interrupted
2. An input signal of a special sequence is entered three times to the reset input within 2 to 5 s after
power-on. 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.)
 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-R is unblocked
3. The following signal to cancel the override state is entered:
• When the external device monitoring function is enabled, the reset input 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 input is turned OFF.
Override state can be also released when the F3SG-RA enters the Lockout state.
