Temperature Input Unit Functions
Section 11-6

tus Flag".
When an off-wire condition is detected, the value of AD conversion data is set
to 7FFF hex (7FFF FFFF when 1/100 Display Mode is being used). When the
input returns to a value within the range that can be converted, the Off-wire
Detection function will automatically be turned OFF, and normal data conver-
sion will resume.
