As process
values
A-96.250.791 / 040219
NOTICE: 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:
 Hydrogen
 Temperature
 Sample Flow (if a flow sensor is selected)
 Saturation
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
value or to drive a control unit. Available functions are:
 Linear, bilinear or logarithmic for process values.
See As process values, p. 61
 Control upwards or control downwards for controllers.
See As control output, p. 63
The process value can be represented in 3 ways: linear, bilinear or
logarithmic. See graphs below.
