DE
DEVIATION (Process Variable minus Setpoint)—
Represents –100 % to +100 % of the selected PV span in
engineering units. FOR EXAMPLE:
Type “T” Thermocouple
PV range = –300 °F to +700 °F
PV span = 1000 °F
Deviation range = –1000 °F to +1000 °F
If PV = 500 °F
and SP = 650 °F
then Deviation Display = –150 °F
Auxiliary Output = 42.5 %
NOTE: A deviation of 0°F yields an auxiliary output of
50 %.
4mA VA
Low Scale Value within the
range of the selected variable
to represent 4 mA
[factory setting = 0]
AUXILIARY OUTPUT LOW SCALING FACTOR—Use a
value in engineering units for all selections above except
Output.
Use value in percent (%) for Output. (Output can be
between –5 % and +105 %.)
20mA V
High Scale Value within the
range of the selected variable
to represent 20 mA
[factory setting = 100]
AUXILIARY OUTPUT HIGH SCALING FACTOR—Use a
value in engineering units for all selections above except
Output.
Use a value in percent (%) for Output. (Output can be
between –5 % and +105 %.)
*When Deviation is selected, only one operating
parameter will be entered. This value represents the
deviation level that will produce 20 mA output. Zero
deviation will produce a center scale (12 mA) output. A
negative deviation equal in magnitude to the Auxiliary
Output High Value will provide a low end (4 mA) output.
