the setting value as 100 P (%). CH

•Stable LIGHT status is obtained with 110 P (%) or more.

•Stable DARK status is obtained with 90 P (%) or less.

You can adjust the sensitivity in increments of 1%. ¨ Refer to P.2.

SETTING SENSITIVITY

Select the sensitivity setting procedure according to the target condition.

For sensitivity adjustment using a moving target

To detect a minute difference

z Two-point Calibration

1. With a target in place, press the SET button and release it. The calibration indicator (yellow LED) lights.

2.With the target removed, press the SET button and

release it. The calibration indicator (yellow LED) goes off.

For target positioning

z Positioning Calibration

1. With no target, press the SET button and release it. The calibration indicator (yellow LED) lights.

2. Place a target in the posi-

					tion where it is to be
					stopped.

CUE: When the sensitivity difference is insufficient

If sensitivity has no allowance after calibration, “------” flashes for 3 seconds on the LCD display monitor.

Note: Sensitivity is set and registered even when the sensitivity difference is insufficient. Be sure to confirm that detection is properly performed.

CUE: Locking the operation button (Key protect)

Hold down [MODE] and [UP] simultaneously for 3 seconds to lock the operation button. When the operation button is locked, “Loc” is displayed in flashing letters.

To unlock the operation button, repeat the procedure above. “vnL” (unlocked) is displayed in flashing letters.

Even when the operation button is locked, display data and channel can be changed.

CHANGE THE SETTING VALUE

You can change the setting value in “excess gain display” mode or “setting value display” mode.

Increase sensitivity (=Decrease the setting value)

z In excess gain display mode

The sensitivity increases by 1% each time you press [UP].

	MODE		MODE
CH	SET	CH	SET

z In setting value display mode

The setting value decreases by 1 each time you press [DOWN].

	MODE		MODE
CH	SET	CH	SET

Decrease sensitivity (=Increase the setting value)

The method for decreasing the sensitivity is the same as for increasing the sensitivity, except you must press [DOWN] instead.

	MODE
CH	SET

CUE: Holding down [UP] or [DOWN] changes the setting value rapidly.

For sensitivity adjustment using an external signal

z External Calibration Function

1.Hold down [MODE] and [UP] simultaneously for 3 seconds to display “Loc”. (If “vnL” appears, repeat the same procedure.)

2.Connect the pink cable to a switch or PLC.

NPN			PNP
Brown		+V	Brown	+V
Blue		0V	Blue	0V
Pink			Pink
	Contact or		Contact or solid state input
	solid-state input

The minimum input time is 20 ms.

3.The external calibration procedure is the same as using the SET button. Turn the input device on instead of pressing the SET button. Also, turn the input device off instead of releasing the SET button. (You can perform all the setting procedures described on the left.)

CUE: Calibration input during detection

You can re-adjust sensitivity during detection without stopping the operation.

The sensor continues operation with the previous sensitivity setting until sensitivity readjustment is completed.

CUE: External calibration with several units

When several units are connected, the sensitivity of all the FS-T2(P) expansion units can be simultaneously set using the external calibration input through the FS-V1(P).

You can select a unit to be externally calibrated by setting its key protection switch to the LOCK position.

External calibration is effective for all the units which are locked. Set the key protection switch to LOCK on the FS-T2(P) expansion unit to be externally calibrated.
