Sensitivity Adjustment

■ PZ-V (Digital type)

● To detect a moving target (Fully-automatic calibration)

Operation	Procedure	Adjustment
	1	Pass a target through the optical axis while
		pressing the SET button.
	2	Confirm that "SEt" flashes on the monitor.
		Release the SET button. The preset value flashes

3several times before the normal display appears.

●To detect a stationary target (Two-point calibration)

		Operation	Procedure	Adjustment
	1	2	1	With no target, press the SET button and release
				it. "SEt" and the current distance flash alternately.

With the target in place, press and release the 2 SET button. The preset value flashes several

times before the normal display appears.

● To obtain maximum sensitivity (Maximum sensitivity setting)

Operation	Procedure	Adjustment
	1	With no target, press the SET button for three
		seconds or more.

	2	Confirm that "SEt" flashes on the monitor.
	3	Release the SET button. The preset value flashes
		several times before the normal display appears.

Note: If the green LED turns off or " - - - " flashes after the calibration, the sensitivity has no allowance. In such a case, adjust the sensor head position, and calibrate again.

● Fine sensitivity adjustment

•When the or button is pressed and released, the numerical value flashes (approx. 2 seconds). This is the preset value. If the or button is pressed again while the preset value flashes, the preset value can be increased or decreased.

•When the or button is held down for 3 seconds or more, the preset value increases/decreases continuously.

● Distance display

•The greater the distance between the target and the sensor head, the larger the displayed value becomes.

•If the target or background is out of the detectable range, is displayed.

Note 1: The distance value indicates a reference value only. It is not an absolute distance.

Note 2: If the target approaches the sensor head closer than the specified range, the displayed value may increase.

* The adjustment for the retroreflective type is the same as for the thrubeam type.

Mutual Interference

•The alternate-frequency type allows mutual interference suppression up to two sensors.

•The alternate-frequency type is not available for the thrubeam type.

•To suppress the mutual interference with the thrubeam type or with three or more sensors, contact KEYENCE.

Sensor Head Orientation

To detect a moving target, consider orientation of the sensor head according to the direction of the movement.
