Set
mA Output Cutoff
in the measurement units used for the process variable. If you change the
measurement unit,
mA Output Cutoff
is adjusted automatically.
•
Default: 0
•
Range: 0 or any positive value
Tip
For most applications the default value of
mA Output Cutoff
should be used. Contact customer service
before changing
mA Output Cutoff
.
Interaction between mA Output Cutoff and process variable cutoffs
When
mA Output Process Variable
is set to a flow variable (for example, mass flow rate or volume flow rate),
mA Output Cutoff
interacts with
Mass Flow Cutoff
or
Volume Flow Cutoff
. The transmitter puts the cutoff
into effect at the highest flow rate at which a cutoff is applicable.
Cutoff interaction
Configuration:
•
mA Output Source
= Mass Flow Rate
•
Frequency Output Source
= Mass Flow Rate
•
mA Output Cutoff
=
10
g/sec
•
Mass Flow Cutoff
=
15
g/sec
Result: If the mass flow rate drops below 15 g/sec, all outputs representing mass flow will report zero flow.

•
Mass Flow Cutoff
=

Result:
•
If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
—
The mA Output will report zero flow.
—
The Frequency Output will report the actual flow rate.
•
If the mass flow rate drops below 10 g/sec, both outputs will report zero flow.
