OPERATING MANUAL HPC & UMC4
14.5.3 Mass flow QM range
This function allows the operator to set the upper-range value for mass flow. The upper-range value takes
on the unit defined using the
Mass flow unit
function. The upper-range value will scale the current and
frequency outputs assigned to mass flow. After choosing the
Mass flow QM range
function and pressing
„Enter“, the following selection field will be displayed:
QM range=100%
XXXXX.XX kg/h
The current upper-range value for mass flow will be displayed. According to the description in section
13.4.3.2 Input window/modify a value, the current value can be changed.
14.5.4 Mass flow QM limit MIN
The MIN limiting value for mass flow can be evaluated via the status output. You enter the value as a
percentage of the set upper-range value. If the mass flow is lower than that limit value, the status output
will be set in case the corresponding assignment has been made. If the alarm function has also been
activated for the assigned current output, the applied current will change to < 3.2 mA or > 20.5 mA /
22 mA. After choosing the
Mass flow QM limit MIN
function and pressing
„Enter“, the following selection
field will be displayed:
Mass flow limit
MIN = 10 %
The current MIN upper-range value for mass flow will be displayed. According to the description in Sec-
tion 13.4.3.2 Input window/modify a value, the current value can be changed.
14.5.5 Mass flow QM limit MAX
The MAX limiting value for mass flow can be evaluated via the status output. You enter the value as a
percentage of the set upper-range value. If the mass flow surpasses this limit value, the status output will
be set in case the corresponding assignment has been made. If the alarm function has also been activat-
ed for the assigned current output, the applied current will change to < 3.2 mA or > 20.5 mA / 22 mA.
After choosing the
Mass flow QM limit MAX
function and pressing
„Enter“, the following selection field will
be displayed:
Mass flow limit
MAX = 90 %
The current MAX upper-range value for mass flow will be displayed. According to the description in Sec-
tion 13.4.3.2 Input window/modify a value, the current value can be changed.
