Operations when Power of the Sensor is Turned on

Operations when Power of the Sensor is Turned on

Operations when the power is turned ON are as follows. Check activation of the BUSY output when
starting operation.

(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 3-11)
“Polarity” (Page 6-28)
“Output Settings” (Page 6-27)

(2) The program number will be determined. If the program switching condition (Page 6-42) is set to

[External IN], the program number is determined according to the inputting condition of the input line.

(3) BUSY output function turns ON.

y

In case of N.O. output, the transistor turns from OFF to ON.

y

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.

y

In case of N.O. output, the transistor turns from ON to OFF.

y

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 is 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.

y

The ON status of each output is as follows.
When Output Settings (Page 6-27) are [N.O.] : Status with NPN or PNP open collector ON.
When Output Settings (Page 6-27) are [N.C.] : Status with NPN or PNP open collector OFF.

y

The RUN output, BUSY output and error output will be output from the output line assigned in output
assignment for program numbers (Page 4-60) determined after the power is turned ON. If the outputs
are not being assigned, it will not be output.
