(e) When "Auto-setting at Input Range Change" is set to "0: Disable" on Switch Setting
Set values in the buffer memory (
Page 351, Appendix 2 (12) (d)) can be out of the setting range. (When
the setting range changes according to the change of the input range, the set value before the change can turn
out of the range.) In this case, a write data error (error code: 4H) occurs in the buffer memory area where
the value turns out of the setting range. Change the input range after setting each buffer memory area with
values within the setting range after the input range change.
(f) Enablement of set contents
Enable the set contents by turning Setting change instruction (YnB) OFF  ON  OFF during the setting
mode (Setting/operation mode status (Xn1): OFF).
(g) Precautions
Soon after the input range is changed, input temperature may be unstable. Do not start the control until
Temperature conversion completion flag (Un\G786) becomes First temperature conversion completed (1H).
