Setting the Installation Distance
■
AUTO mode
Enter the current distance "d" between the workpiece and the Sensor Head.
Enter the sensor distance value again when the relationship between the static electric
sensor and the displacement sensor changes.
■
FIX mode
Fix the static electricity sensor (ZJ-SD) and the laser sensor (ZX-LD__) or static
electricity sensor (ZJ-SD) and the ultrasonic sensor (ZX-UD__) to the exclusive
mounting bracket (ZJ-XBU1). Simply setting the FIX mode frees you from the need to
input the distance value.

Amplifier automatically recognizes distance B
(A-d) between displacement sensor and static
electricity sensor by input of "d".
Change in distance with workpiece is sensed
based on this value, and electric potential
value is corrected.
