2. Configure the Formula mathematical function: Source A = input signal phosphate
and Source B = input signal volume flow.
 Formula:
A*B*x
(where x is an application-specific proportionality factor)
3. Select this formula as the source e.g. of the current output or of a modulated binary
output.
4. Connect the valve or pump.
10.7.6 Diagnostic modules
Here you can configure a maximum of 8 individual diagnostic messages.
A diagnostic module has the following properties:
• The feed source can be configured like a binary output (relay, digital output).
• You can choose whether the diagnostic message should be output at a high level or low
level.
• You decide which error category (Namur class) should be assigned to the message.
• You can define a customized text to be output as the diagnostic message text.
In addition you can switch off the factory diagnostic code for limit switches. This allows
you to:
• Use the limit switch on a purely functional basis (without a message)
• Configure application-specific message texts
• Control diagnostic modules directly by a digital signal or via a limit switch output
(enables the use of switch-on/switch-off delay, for example).
