▶ EU, EUS are used to explain the interior parameter of controller.
☞ EU( ) : Engineering unit value according to instrument range.
☞ EUS( ) : Engineering range according to instrument span.
▶ Range of EU( ), EUS( )
RANGE CENTER POINT
EUS -100 ~ 100% RL ~ RH | RH – RL | / 2 + RL
EUS -100 ~ 100% - ( | RH – RL | + | RL | ) ~ RH RL
EUS -100 ~ 100% 0 ~ | RH – RL | | RH – RL | / 2
EUS -100 ~ 100% - | RH – RL | ~ | RH – RL | 0
▶ INPUT = T C(TC-T)
▶ RANGE = -200.0℃(RL) ~ 400.0℃(RH)
RANGE CENTER POINT
EUS -100 ~ 100% - 200.0 ~ 400.0℃ 100.0℃
EUS -100 ~ 100% - 800.0 ~ 400.0℃ - 200.0℃
EUS -100 ~ 100% 0 ~ 600.0℃ 300.0℃
EUS -100 ~ 100% - 600.0 ~ 600.0℃ 0.0℃
☞ ABS doesn’t change along input of absolute value.
