*1. Also used as Override input line.
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.
