10.7.4 Mathematical functions
In addition to "true" process values provided by connected physical sensors or analog inputs, you
can have maximum 6 "virtual" process values calculated using mathematical functions.
The "virtual" process values can be:
• issued via a current output or fieldbus
• used as a control variable
• assigned as a measured variable to a limit contactor
• used as a measured variable to trigger cleaning
• displayed in user-defined measuring menus.
Difference
You can subtract the measured values of two sensors and use the result to detect incorrect
measurements, for example.
To calculate a difference, you must use two measured values with the same engineering unit.

Info
Start signal
Options
• Bus signals
• Signals of digital or ana-
log inputs
• None
Factory setting
None
In addition to cyclic cleaning, you can also use an input
signal to start event-controlled cleaning.
Choose the trigger for such a cleaning process here.
Interval programs and weekly programs are executed as
normal, i.e. conflicts can occur. Priority is given to the
cleaning program that was the first to be started.
Hold
Options
• On
• Off
Factory setting
On
Decide whether there should be a hold during the clea-
ning process. This hold affects the inputs to which this
cleaning process is assigned.
Start single
Action
Start an individual cleaning process with the selected
parameters.
If cyclical cleaning is enabled, there are times in which it
is not possible to manually start the process.
Manual mode
Action
You start the manual mode by acknowledging the war-
ning. You can now start each possible cleaning step
manually. If you want to return to cyclical cleaning, you
must set "Manual mode" to "Off".
Stop or Stop Failsafe
Action
End the cleaning process (cyclical or manual)
Output selection
Goes to the "Outputs" menu
You can assign the cleaning program directly to one or
more outputs.
