Current output range
Options
• 0 to 20 mA
• 4 to 20 mA
Factory setting
4 to 20 mA
In accordance with Namur NE43, the linear range
extends from 3.8 to 20.5 mA (Current output
range="4 to 20 mA") or from 0 to 20.5 mA (Current
output range="0 to 20 mA"). If the range is exceeded or
undershot, the current value stops at the range limit and
a diagnostics message (460 or 461) is output.
Error current
0.0 to 23.0 mA
Factory setting
21.5 mA
The function meets NAMUR NE43.
Set the current value that should be output at the
current outputs in the event of an error.
The value for "Error current" should be outside the measuring range. If you decided that your Current output range
= "
0 to 20 mA", you should set an error current between 20.1 and 23 mA. If the Current output range
= "4 to 20 mA" you could also define a value < 4 mA as the error current.
The device allows an error current within the measuring range. In such instances pay attention to possible affects
this may have on your process.
Alarm delay
0 to 9999 s
Factory setting
0 s
The system only displays the errors that are present
longer than the set delay time. This makes it possible to
suppress error messages that only occur briefly and are
caused by normal process-specific fluctuations.
Device Hold
Options
• Disabled
• Enabled
Factory setting
Disabled
You can enable an immediate, general hold (for sensors)
here. The function has the same effect as the "HOLD" soft
key in the measuring screens.
