6.3.3.4 Celsius / Fahrenheit
0_> Celsius
1 Fahrenheit
Figure 6.3.3.4/1: “Celsius / Fahrenheit“
You can select the temperature unit that will be used for all displays and entries here.
Conversion occurs automatically.
6.3.3.5 Sensor selection
0_> PT100
1 NI120
Figure 6.3.3.5/1: “Sensor selection“
Select the type of the temperature sensors used in the hoses and manual units here.
Please note that mixed operation of hoses with PT100 and NI120 sensors is not possible.
Attention!
Choosing the wrong sensor may lead to damage of the heatable hose or the manual
units.
6.3.3.6 Control parameters
_ Tank
P: 100
I: 10
D: 10
Figure 6.3.3.6/1: “Control parameters”
The control parameters (proportional, integral, and differential ratio of controller behavior)
for the individual components are displayed and can be changed here as necessary.
Only
implement changes to the parameters if the components of the system (hoses, manual
application units) have been replaced by units with strongly deviating temperature behav-
iors.
Use the integrated optimization method (see next chapter) to determine and set the pa-
rameters.
Attention!
The controller parameters affect the entire operating behavior of the tank system. Only
implement manual parameter changes in justified cases and with knowledge of how a
PID controller functions. Inappropriate settings can endanger the operability of the tank
system.
