You can use this menu to parameterize the analog outputs. This
input always refers equally to all components.
8411
You can set the following start-of-scale values for the analog
current range in the 3rd line:
4 / 20 mA
• 0 mA
• 2 mA
84111
• 4 mA
• NAMUR
You can switch suppression of negative measured values on or
off in the 4th line. The "ON" option is preset, and means that
negative measured values can also be output. With a setting of
2 or 4 mA as the lower limit, values below this down to 0 mA can
therefore be output, i.e. negative measured values can be dis‐
played (live zero).
If the output of negative measured values is switched off ("OFF"
position), the current output is limited to the start-of-scale value.
4 / 20 mA
If 2 or 4 mA is set as the lower limit, the output is now indeed
limited to 2 or 4 mA. In the adjacent display, the start-of-scale
84111a
value of the analog current range is set to 4 mA.
