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.
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 output 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 54 .
Reset Menu (
reset
)
The Reset menu is used to reset the maximum or
minimum reading (peak or valley) reached by the
process; both may be reset at the same time by
selecting “reset high & low” (
rst HL
). The tare value
used to zero the display may be reset by selecting
“reset tare” (
rst tr
).
Manual Control Menu (
Contrl
)
The Manual Control menu is used to control the
4-20 mA analog output 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.
