Setting Various Functions
IL-E
When the zero shift is performed with the external input, make the setting for the nonvolatile
memory (EEPROM) to save the shifted status.
When the zero shift is performed with the sensor amplifier button operation, it is saved on
the nonvolatile memory (EEPROM) regardless of the setting.
“3-5 Zero Shift Function (Shifting the Internal Measurement Value (R.V.))” (page 3-18)
This function allows the amplifier to prevent the mutual interference caused by light
interaction between sensor heads.
If the "mutual-interference prevention function setting" is ON, the function is effective
between adjacent amplifiers.
When set to OFF, the laser emission timing is synchronized if the sampling rate is the same
within "(number of amplifiers - 1) x 5 μs".

Point
If the data is written in the nonvolatile memory (EEPROM) over 1
million times, the error message is displayed and the setting may not
be saved any more. (It is still possible to obtain a measurement value.)
"Error Displays and Corrective Actions" (page A-4)
For such cases as the zero shift occurring frequently from the PLC,
and, it is not necessary to store it in the nonvolatile memory
(EEPROM), it is recommended to set it as OFF.
