KEYENCE FS-32C(P) - Manual (Page 3)

Area Detection Mode
This mode is suited to detecting the received light intensity only of a certain range.
To set this mode, select the area detection mode at Detection mode selection (page 4, No.4).
Set the value so that the upper limit setting value is
larger than the lower limit setting value.
The unit does not respond when the upper limit set-
ting value is less than or equal to the lower limit set-
ting value.
„ How to switch the upper limit setting value (HI) and the lower
limit setting value (LO)
When the button is pressed, “HI” or “LO” and the setting value alternately flash.
When the MODE button is pressed while the display alternately flashes, the “HI” or
“LO” display changes. How to configure the sensitivity setting is the same as
when in the normal detection mode.
Setting the Display Scaling
This is the function to adjust the current received light intensity to the ìscaling tar-
get value.
1
When selecting a display value correction function (page 5, No. 6), select the
display scaling function, and set the target value.
2
During the normal display, press the SET button while pressing the MODE button.
(Scaling is performed for the current light intensity at this time.)
The reference light intensity can be set in the following range in reference with the
currently received light intensity:
• No value can be set when the Edge detection mode is selected.
• The value is stored in memory even after the power is turned off.
• The value is not reflected to the analog output of the FS-V31M.
• When using FS-V31C(P)/32C(P), external inputs can be used.
Zero-shift Function
The Zero-shift function is used to forcibly set the current light intensity to zero.
1
At Display value correction function selection (page 5, No.6), select “Zero-shift function”.
2
When the SET button is pressed while the MODE button is pressed, the current
light intensity is forcibly set to zero.
• This function cannot be used when the Dynamic sensitivity correction (DSC) or
Edge detection mode is selected.
• The value is stored in memory even after the power is turned off.
• The value is not reflected to the analog output of the FS-V31M.
• When using FS-V31C(P)/32C(P), external inputs can be used.
External Input [Function only for FS-V31C(P)/V32C(P)]
1
Signals can be input externally by selecting an external input function (page 4, No. 4-C).
2
The signal can be accepted by short-circuiting the pin (2) for 2 ms or more as
shown below for each model (20 ms for OFF).
* For FS-V31C/31CP only.
• Setting using an external input is up to 1 million times.
• No inputs are accepted while setting each mode.
When external calibration is selected, the operation is the same as with the SET button.
„ Special Function
By performing the following operation, both sensitivity setting and scaling can be
performed using external input. Select external calibration (page 4, No. 4-C) and
display scaling. The following is the example when using the % calibration.
Display Selection
The factory default value is “1” only. Other items can be displayed only after being
selected at Display customization selection (page 5, No.8).
*1 When ULTRA/MEGA mode is selected, the current received light intensity can
be displayed up to 5 digits.
The setting value flashes when the
button is pressed once.
The setting can be changed by pressing the button while flashing.
*2 The excess gain is displayed in a 5% increment from 85 to 115%.
*3 The current light intensity for the setting value is displayed in percentage.
*4 Holds and displays the peak value and the bottom value.
How to reset the peak and bottom values (with the 5/6 display)
While pressing the MODE button, press the SET button for 3 seconds or longer to reset
the peak and bottom values. Turning the power off also resets the values.
With FS-V31C(P)/32C(P), the value can be reset externally by selecting Reset at
External input function selection (page 4, No.4-C).
„ User-friendly Functions (Direct Access Menu)
The hold display (5/6) can be set in detail by pressing the button for 2 seconds or longer.
The power mode and attenuation function for the power mode display (3) can be
set by pressing the
button for 2 seconds or longer.
Key Lock Function
The key lock function disables the operation of all keys.
1
While pressing the MODE button, press the ( ) button for at least three seconds.
The same steps can be taken to deactivate key lock.
For more information on the key lock levels and the PIN number key lock function,
refer to page 6.
Even when the above condition is satisfied, the unit
may not respond when the HI and LO values are close
to each other because of hysteresis. Be sure to oper-
ate the unit to check whether the values are valid.
Power mode Minimum value Maximum value
If the value exceeds the
range, 'TT is displayed
and scaling is performed
up to the possilbe range.
