(1) After the power is turned ON, the I/O Settings (NPN or PNP and N.O. or N.C.) will be determined.
“Operation for initial startup of the sensor” (Page 3-12)
“Polarity” (Page 7-11)
“Output Settings” (Page 7-11)
(2) The program number will be determined. If [Switch Program by External Input] (Page 7-14) is set to [External Input], the program
number is determined according to the condition of the input lines.
(3) BUSY output turns ON.

In case of N.O. output, the transistor turns from OFF to ON.

In case of N.C. output, the transistor turns from OFF to OFF, so no changes occur.
(4) The BUSY output turns OFF and the system starts to operate.

In case of N.O. output, the transistor turns from ON to OFF.

In case of N.C. output, the transistor turns from OFF to ON.
By checking the activation of the BUSY output, operation in N.O./N.C. can be checked.
(5) If the startup error has occurred, the error output turns ON during the BUSY status.
(6) The RUN output turns ON when the sensor is running with no system error occurring.


The “SD card save stop” input is valid only during operation.
Do not turn o󰀨 the system power while the SD card is being accessed. Otherwise, all or part of the setting data
may be lost or the memory may be damaged.

The ON status of each output is as follows.
When Output Settings (Page 7-11) are [N.O.]: Status with NPN or PNP open collector ON.
When Output Settings (Page 7-11) are [N.C.]: Status with NPN or PNP open collector OFF.

The RUN output, BUSY output and error output will be output from the output line assigned in output assignment (Page 4-149) for
program numbers determined after the power is turned ON. If the outputs are not being assigned, it will not be output.
