System Operation and Functions
• External Device Monitoring not used and in Manual Reset mode
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 on startup
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. Under exit-only muting mode
2. F3SG-SR/PG is blocked
3. Under the state of 2 and 5, a special sequence is entered to the reset input three (3) times. The
signal must be entered within a range from 0.1 s to the override input time limit T1 (1 s)(can be
changed). (See the timing chart below.)

Override end condition on startup
Override is canceled when either one of the following conditions is met.
1. When 600s (can be changed) passes under the override state
2. When F3SG-SR/PG is unblocked
3. The following override cancel signal is provided
• When the external device monitoring function is enabled, reset input is ON (PNP: Connected to Vs-
3V to Vs, NPN: Connected to 0V to 3V)
