TEMPERATURE SCALE
F
Fahrenheit
C
Celsius
Select either degrees Fahrenheit or Celsius. If changed, check related
parameter values.
Temperature Input Type only.
DECIMAL RESOLUTION
0
to
0.0
for temperature inputs
0
to
0.000
for process inputs
Select whole degrees, or tenths of degrees for Temperature display,
Setpoint values, and related parameters. For thermocouple types R, S,
and B, only whole degrees of resolution is available. For process inputs
up to three decimal point resolution is available.
INPUT FILTER BAND
1
to
100
display units
The filter will adapt to variations in the input signal. When the variation
exceeds the input filter band value, the digital filter disengages and a
noise discrimination filter engages that rejects noise bursts. When the
variation becomes less than the band value, the digital filter engages
again. The value of the band is in display units.
SETPOINT LOW LIMIT
-999
to
9999
input range dependent
The controller has a programmable low setpoint limit value to restrict
the range of the setpoint. Set the limit so that the setpoint value cannot
be set below the safe operating area of the process.
DIGITAL FILTERING
0
= least to
50
= most
The filter is an adaptive digital filter that discriminates between
measurement noise and actual process changes. The equation for
digital filtering is:
PV =
Where:
n = Digital Filtering selection
If the signal is varying greatly due to measurement noise, increase the
filter value. Decrease the filter value for quicker controller response.

DISPLAY VALUE SCALING POINT 1
-999
to
9999
Enter the first coordinate zero scale Display Value associated with the
lower range (0V/mA, 4mA) of the input signal, by using the arrow keys.
Process Input Type only.
DISPLAY VALUE SCALING POINT 2
-999
to
9999
Enter the second coordinate full scale Display Value associated with
the upper range (5V, 10V, etc) of the input signal, by using the arrow
keys.
Process Input Type only.
SHIFT/OFFSET
-99
to
999
display units
This value offsets the controller’s display value by the entered
amount. This is useful in applications in which the sensor does not
provide an accurate signal.

SETPOINT HIGH LIMIT
-999

input range dependent
The controller has a programmable high setpoint limit value to restrict
the range of the setpoint. Set the limit so that the setpoint value cannot
be set above the safe operating area of the process.
