Note: The navigation in the menu <Signal Output 1> and <Signal
Output 2> is equal. For reason of simplicity only the menu
numbers of Signal Output 1 are used in the following.
Signal Output 1 and 2: Assign process value, the current loop
range and a function to each signal output.
Parameter: Assign one of the process values to the signal output.
Available values: Phosphate, Sample Flow.
Current Loop: Select the current range of the signal output.
Make sure the connected device works with the same current range.
Available ranges: 0–20 mA or 4–20 mA
Function: Define if the signal output is used to transmit a process val-
ue or to drive a control unit. Available functions are:
 Linear, bilinear or logarithmic for process values.
See As process values, p. 72
 Control upwards or control downwards for controllers.
See As control output, p. 74
The process value can be represented in 3 ways: linear, bilinear or
logarithmic. See graphs below.
