Scaling the 4-20 mA Analog
Output (
Aout
)
The 4-20 mA analog output can be scaled to provide
a 4-20 mA signal for any display range selected. To
select the channel and source assignments the
analog output is assigned to, see
Analog Output
Source on page 58 .
No equipment is needed to scale the analog output;
simply program the display values to the
corresponding mA output signal.
The
Analog Output menu is used to program the
4-20 mA outputs based on display values.
For further details, see Setting Numeric Values
on page 34 , Analog Output Value for Loss of
4-20 mA Input (Loop Break) on page 58.
Reset Menu (
reset
)
The Reset menu is used to reset the maximum (peak)
value of Ch-A and Ch-B rate (
rst Hi
), minimum
(valley) reading of Ch-A and Ch-B rate (
rst Lo
), both
high and low value of Ch-A and Ch-B rate (
rst HL
),
Ch-A total (
tot A
) or Ch-B total (
tot B
), Ch-A grand
total (
Gtot A
) or Ch-B grand total (
Gtot B
), both
Ch-A and Ch-B totals (
tot AB
), or both Ch-A and
Ch-B grand totals (
Gt AB
).
Manual Control Menu (
Contrl
)
The Manual Control menu is used to control the
4-20 mA analog output (Aout 1 only) and the relays
manually, ignoring the input. Each relay and analog
output can be programmed independently for manual
control. Selecting automatic control sets all relays and
analog output for automatic operation.
