7.2.6.6
Density limit MIN
The MIN limiting value for density can be evaluated via the status output and thus triggers an external alarm.
This value is entered as an absolute value in the unit defined using the Density unit function.
After selecting the Density limit MIN function, press “
” to display the following selection field:
Density limit
MIN = 0000.0 g/l
The current MIN limiting value will be displayed and can be changed by toggling the arrow keys.
Pressing the “
” key confirms the entry.
7.2.6.7
Density limit MAX
The MAX limiting value for density can be evaluated via the status output. This value is entered as an absolute
value in the unit defined using the Density unit function.
After selecting the Density limit MAX function, press “
” to display the following selection field:
Density limit
MAX = 0000.0 g/l
The current MAX limiting value will be displayed and can be changed by toggling the arrow keys.
Pressing the “
” key confirms the entry.
7.2.6.8
Density limit hysteresis
The hysteresis of the density limiting values indicates the absolute density value in the unit defined using
Density unit function. The measured density must fall below or surpass the set limiting values by the set
hysteresis value in order to activate or deactivate the function.
After selecting the Density limit hysteresis function, press “
” to display the following selection field:
Density limit
Hysteresis 000.0 g/l
The current limit hysteresis value will be displayed and can be changed by toggling the arrow keys.
Pressing the “
” key confirms the entry.
