Unit
Select F, C, or nonE.
F
°F descriptor is On and temperature inputs will be
displayed in actual degrees Fahrenheit.
C
°C descriptor is On and temperature inputs will be
displayed in actual degrees Celsius.
nonE
°F and °C descriptors will be Off. This is only available
with Current and Voltage Inputs.
dPt
Decimal Point Positioning: Select 0, 0.0, 0.00, or 0.000. On
temperature type inputs this will only effect the Process Value,
SP1, SP2, ALLo, ALHi, 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.
InPt
Input Fault Timer: Select OFF, 0.1 to 540.0 minutes. Whenever
an Input is out of range, shorted, or open the timer will start. When
the time has elapsed, the controller will revert to a safe condition
(Outputs Off, Flashing Displays). 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
Thermocouples and RTD’s.
SCAH
Scale High: Select 100 to 9999 counts above SCAL. The total
span between SCAL and SCAH must be within 11998 counts.
Maximum setting range is -1999 to +9999 counts. For Current and
