SETTING SENSITIVITY
Select the sensitivity setting procedure according to the target condi-
tion.
For sensitivity adjustment using a moving target
z Fully-automatic Calibration
To detect a minute difference
z Two-point Calibration
For target positioning
z Positioning Calibration
For stable detection unaffected by dust
z Maximum Sensitivity Setting
CHANGE THE SETTING VALUE
You can change the setting value in “excess gain display” mode or “set-
ting 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].
z In setting value display mode
The setting value decreases by 1 each time you press [DOWN].
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.
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.
The minimum input time is 20 ms.
3. The external calibration procedure is the same as using the SET but-
ton. 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.)
1. Pass a target through the
optical axis while press-
ing the SET button.
2. Confirm that the calibra-
tion indicator (yellow LED)
flashes.
3. Release the SET button.
The calibration indicator
(yellow LED) goes off.
1. With a target in place, press
the SET button and release it.
The calibration indicator (yel-
low LED) lights.
2. With the target removed,
press the SET button and
release it. The calibration
indicator (yellow LED) goes
off.
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.
3. Press the SET button until
the calibration indicator
flashes.
4. Release the SET button.
1. Under the following con-
ditions press the SET
button until the calibration
indicator (yellow LED)
flashes.
2. Release the SET button.
The calibration indicator
(yellow LED) goes off.
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 differ-
ence is insufficient. Be sure to confirm that detection is properly per-
formed.
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 dis-
played 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.

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 calibra-
tion input through the FS-V1(P).
You can select a unit to be externally calibrated by setting its key pro-
tection 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.
