4.4 Configure mA outputs
mA outputs
There is 1 mA output provided on the standard analyzer configuration. An additional
mA output is available if the analyzer
is supplied with an ‘options PCB’. Supervisor
level is required to configure mA output.
Each output can be assigned to one of 4 measurement properties (e.g. gas
measurement 1 or gas measurement 2, or pressure or temperature [mA input]) or
the transmission.
The mA output provides a constantly updated output, in which the current
represents the value of the measurement.
The analyzer allows you to specify two separate range configurations for the mA
outputs, range 1 and range 2.
The mA output can be selected as:
0
–
20 mA 0 mA represents the lowest sample measurement and 20 mA
represents the highest sample measurement in the range
specified
4
–
20 mA 4 mA represents the lowest sample measurement and 20 mA
represents the highest sample measurement in the range
specified
You can also specify how the mA output operates during calibration, a fault
condition and under-range conditions.
Note: For applications where the fault relay is not being used, configure the mA output
to 4 -20 mA and jam low (default setting) for safety and to prevent any analyzer
faults going undiagnosed. This is the safest mode of operation.
