STB 67 Totalizer 1 ► Low cut Totalizer 1 ► Total 1 Lowcut
Specifies the low-cut value of
totalizer 1.
STB 76 Totalizer 2 ► Low cut Totalizer 2 ► Total 2 Lowcut
Specifies the low-cut value of
totalizer 2.
An actual value which makes low cutting effective has ± 0.5% hysteresis from the set low-
cut value. The hysteresis width on the negative side (going into the low cut when flow rate is
decreasing) and the positive side (going out of low cut when flow rate is increasing) are as
follows:
(1) Negative side
= Low-cut setpoint - (Minimum span set with multi range x 0.5%)
(2) Positive side
= Low-cut se (Minimum span set with multi range x 0.5%)
Example: When setting to span of volumetric flow rate = 10.0 m3/h,
Low-cut value = 1.0 m3/h
(1) Negative side
= 1.0 [m

/h] – (10.0 [m

/h] x 0.5 [%])
= 0.95 [m
