Liquiline CM44P Operation
Endress+Hauser 65
Menu/Setup/General settings
Function Options Info
Current output range Selection
• 0..20 mA
• 4..20 mA
Factory setting
4..20 mA
In accordance with Namur NE43, the linear
range is from 3.8 to 20.5 mA (4..20 mA) or
from 0 to 20.5 mA (0..20 mA). If the range is
exceeded or undershot, the current value stops
at the range limit and a diagnostic message (460
or 461) is output.
Failure current 0.0 to 23.0 mA
Factory setting
22.5 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 Failure current should be outside the measuring range. If you decided that your Current
output range = 0..20 mA you should set an error current between 20.1 and 23 mA. If the Current
output range = 4..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 any
effects this may have on your process.
Alarm delay 0 to 9999 s
Factory setting
0 s
The software displays only the errors that are
present longer than the set delay time. This
makes it possible to suppress messages that only
occur briefly and are caused by normal process-
specific fluctuations.
Device hold Selection
• Disabled
• Enabled
Factory setting
Disabled
You can enable an immediate, general hold (for
sensors) here. The function acts in the same way
as the HOLD soft key in the screens.
