A positive limit will be compared to the totalizer value for the positive flow direction.
A negative limit will be compared to the totalizer value for the negative flow direction.
The comparison will also take place if the totalizer of the other flow direction is displayed.
21.6.3 Defining the Hysteresis
A hysteresis can be defined for the alarm output R1 to prevent a constant triggering of
the alarm due to small fluctuations of the measured values around the limit.
The hysteresis is a symmetrical range around the limit. The alarm will be activated if the
measured values exceed the upper limit and deactivated if the measured values fall be-
low the lower limit.
Note! The unit of measurement of the limit corresponds to the unit of mea-
surement of the selected physical quantity.
If the unit of measurement of the physical quantity is changed, the
limit has to be converted and entered again.
example 1: physical quantity: volumetric flow rate in m
3
/h
Quantity Limit:: 1 m

example 2: physical quantity. volumetric flow rate in m
3
/h
Low Limit::60 m

/h
The unit of measurement of the physical quantity is changed to m
3
/min.
The new limit to be entered is 1 m

/min.
example: High Limit:: 30 m
