…Input/Output / … …Analog Input 1 (4)
Filter Time
The input is averaged over the time set.
Fault Detect
Sets a tolerance level (in % of engineering range) to allow for deviation of the input signal
above or below the engineering range before an input failure is detected.
Zero Adjustment
Span Adjustment
The
Zero Adjustment
and
Span Adjustment
parameters enable fine tuning of the inputs to
eliminate system errors. Apply a known input value and adjust until the required input value
is displayed.
Normally,
Zero Adjustment
is used with input values close to
Eng Low
(adjustment is
performed by applying an offset to the reading) and
Span Adjustment
is used with values
close to
Eng High
(adjustment is performed by applying a multiplier to the reading).
Analog Outputs
The analog outputs can be configured to retransmit any analog value and have a
configurable range from 0 to 24 mA. Output 1 can also be configured to function as a digital
output.
Analog Output 1 (2)
Note
.
Analog Output 2
is available only if an option board is fitted – see pages 15 (CM10),
16 (CM30) and 17 (CM50).
Output Type
Selects the analog or digital output (applicable only to Analog Output 1).
Source
Selects the parameter to be assigned to the output – see Appendix A, page 116 for
description of sources.
