The amount of received light when the sensor head is mounted for the first time is
registered as the reference light amount.
Perform “reference light registration (gain adjustment)” when using the sensor for
the first time or each time the sensor head mounting position has been changed,
etc.
1
Adjust the beam axis.
2
Press the [MODE] and [SET] buttons on the main screen
simultaneously for 2 seconds.
[#.K)P] will display on the main display (upper level), and the reference light
amount will be registered. The main screen will reappear when the registration
is completed.
There are two types of tolerance setting values: HIGH (upper limit) and LOW (lower
limit). The value displayed will output its signal as one of the following 3 levels:
When the value exceeds the upper limit (HIGH); when the value is within the
tolerance range (GO); and when the value falls below the lower limit (LOW).
"4. Output mode [QWV]" (Page 8)
„ Automatic setting (Tolerance tuning)
When a reference workpiece (master workpiece) is available, HIGH tolerance value
(upper limit) and LOW tolerance value (lower limit) can be automatically set
symmetrically with respect to the measured value of the master workpiece.
1
Press the W/X button several times on the
main screen. Display the R.V. (internal
measurement value) on the sub display (lower
level). ([R.V.] will turn on.)
2
Measure the master workpiece, and then press the [SET] button.
The P.V. (judgment value) is imported as the tolerance setting reference value.
[5GV] and the tolerance setting value will alternately display on the sub display
(lower level).
3
Set the tolerance width with the S/T button,
and then press the [SET] button.
4
Press the [SET] button to complete the tolerance tuning.
[5GV] blinks on the main display (upper level), and the HIGH setting value and
LOW setting value are determined. Then, the display returns to the R.V. screen
automatically.
„ Automatic setting (2-point tuning)
If there are an acceptable target and a HIGH or LOW limit defective target, the
middle value between the acceptable and the HIGH or LOW limits can be set as the
tolerance value.
1
Press the W/X button several times on the
main screen. Display the HIGH setting value on
the sub display (lower level). ([R.V.] will turn
on.)
2
Measure an acceptable target, and press the [SET] button.
The R.V. (internal measurement value) will be imported.
[*K5'V] will appear on the main display (upper level).
3
Measure a HIGH limit defective target, and press the [SET]
button.
The R.V. (internal measurement value) will be imported.
After [5'V] blinks on the main display (upper level), the P.V. (judgment value) will
appear.
The middle value between the measurement value of the acceptable target
measured in Step 2 and the measurement value of the HIGH limit defective
target will appear on the sub display (lower level).
This completes setting the HIGH setting value (upper limit).
4
Press the X button once, and display the LOW
setting value on the sub display (lower level).
5
Measure the acceptable target again, and press
the [SET] button.
The R.V. (internal measurement value) will be imported.
[.Q5GV] will appear on the main display (upper level).
6
Measure a LOW limit defective target, and press the [SET] button.
The R.V. (internal measurement value) will be imported.
After [5GV] blinks on the main display (upper level), the P.V. (judgment value) will
appear.
The middle value between the measurement value of the acceptable target
measured in Step 5 and the measurement value of the LOW limit defective
target will appear on the sub display (lower level).
This completes setting the LOW setting value (upper limit), and completes
2-point tuning.
„ Manual setting
Set the HIGH setting value (upper limit) and LOW setting value (lower limit) to an
arbitrary value.
1
Press the W/X button several times on the
main screen. Then display the HIGH setting
value on the sub display (lower level).
2
Press S/T button to set the HIGH setting
value.
3
Press the X button once and display the LOW
setting value on the sub display (lower level).
4
Press the S/T button to set the LOW setting
value.
The tolerance settings are complete.
When the [ZERO SHIFT] button is pressed or the external zero shift input* has been
activated, the R.V. (internal measurement value) now becomes the newly shifted
target value.
* Zero shift via external input is provided by assigning zero shift input to the
external input 1 (pink wire).
„ Setting the shift target value
1
Use the W/X button on the main screen to display the shift target
value on the sub display (lower level).
2
Press the S/T button to change the shift target value.
The shift target value has now been set.
„ Performing the zero shift
Press the [ZERO SHIFT] button or assign zero shift input to an external input.
The zero shift indicator [ZERO SHIFT] will light up for approx. 0.5 seconds and the
current R.V. (internal measurement value) will now become the shifted target value.
„ Cancelling the zero shift
Press the zero shift button [ZERO SHIFT] for 2 seconds or more.
The sub display shows [T'5'V], indicating that the zero shift has been cancelled
and set back to the factory setting.
Reference Light Registration
(Gain Adjustment)
• Reference light registration (gain adjustment) cannot be
carried out with external inputs. It must be carried out
with the buttons on the main unit.
• If reference light registration (gain adjustment) is
attempted when the received light is low, an error will
appear and the registration will be canceled.
