dPt Decimal Point Positioning: Select 0, 0.0, 0.00, 0.000, or .0000.
On temperature type inputs this will only effect the Process
Value, SP1, SP2, and InPC. For Current and Voltage Inputs all
Menu Items related to the Input will be affected.
0
No decimal Point is selected. This is available for all
Input Types.
0.0 One decimal place is available for Type J, K, E, T, L,
RTD’s, Current and Voltage Inputs.
0.00 Two decimal places is only available for Current and
Voltage Inputs.
0.000 Three decimal places is only available for Current and
Voltage inputs.
.0000 Four decimal places is only available for Current and
Voltage inputs.
diSP Home Display: Select Pro, SPt, or both.
Pro
The upper display of the HOME display shows the
current Process Variable. The lower display is blank.
SPt The upper display of the HOME display shows the
current Set Variable. The lower display is blank.
both The upper display of the HOME display shows the
current Process Variable. The lower display shows the
current Set Variable.
InPt Input Fault Timer: Select OFF, 0.1 to 540.0 minutes. Whenever an
Input is out of range (UFL or OFL displayed), shorted, or open the
timer will start. When the time has elapsed, the controller outputs
will be forced into their de-energized states. If OFF is selected, the
Input Fault Timer will not be recognized (time = infinite).
SEnC Sensor Rate of Change: Select OFF, 1 to 4000 °F, °C, or counts
per 1 second period. This value is usually set to be slightly greater
than the fastest process response expected during a 1 second
period, but measured for at least 2 seconds. If the process is faster
than this setting, the SEnC bAd error message will appear. The
outputs will then be turned off. This function can be used to detect
a runaway condition, or speed up detection of an open thermo-
couple. Use the INDEX & ENTER keys to reset.
SCAL Scale Low: Select 100 to 9999 counts below SCAH. The total span
between SCAL and SCAH must be within 11998 counts. Maximum
setting range is -1999 to +9999 counts. For Current and Voltage
inputs, this will set the low range end. Viewable only for Thermo-
couple and RTD ranges.
