Disabling the full auto preset function

When the PST indicator is lit, press and hold the [PRESET] button.

• The PST indicator turns off, indicating that the full auto preset function has been

disabled.

Each preset function cannot be used when the following functions
are set. Disable the function or change the setting before executing
the preset function.
• Zero shift function -> "Zero Shift Function" (page 3-17)
• Zero shift calibration ->

"Adjusting the Sensitivity" (page 3-5)

• Zero shift input ->

"External Input" (page 4-17)

• DATUM 1/2 mode -> "Restrictions for Sensitivity Settings in Each

Detection Mode" (page 6-8)

• Rising/falling edge detection mode" -> "Restrictions for Sensitivity

Settings in Each Detection Mode" (page 6-8)

• The preset function is not suited for transparent workpieces such

as thrubeam/retro-reflective models and other cases of detection
with low light intensity differences.

• After changing any of the following settings, disable each preset

function once and then execute again.

"Power Modes" (page 4-4)
"Preset Saturation Function" (page 4-27)
"Display Gain" (page 4-30)
"Sensitivity" (page 4-32)

• If the received light intensity raw value is 50 or less (200 or less

when the light intensity is set to FuLL), the display will be "100.0" or
less when the preset function is executed.

• If the [PRESET] button is pressed when the preset function is enabled

(PST indicator is lit), the current received light intensity changes to
"100.0" and the setting value does not change.

• Expansion units can be preset with operations from the main unit.

"Common Key-Operations Function" (page 4-32)

• Periodic presetting is possible with signals input from an external source.

"External Input" (page 4-17)

• With the preset function, a process is carried out to ignore minute

received light intensity changes which do not affect the detection. The
change amount to be ignored can be adjusted randomly.

"Preset Saturation Function" (page 4-27)

If the sub-display is changed to "Extension", the original received light
intensity can be confirmed even when using the preset function.
