Watlow F4T • 210 • Chapter 5 Function Reference
Signals
Direction Label Type Function
Transmitter - - - - Analog
The scaled electrical signal or process value with filter
and offset applied
Name
Uniquely identify this FB using up to 20 alphanumeric characters.
Sensor Type
To detect and condition a input current for use with other FBs, set Sensor Type to Milliamps.
Units
Set the units for the function’s output.
Options:
• Power: the output is a percentage with 100% representing full power and 0% represent-
ing no power.
• Process: the output is in units of measure other than degrees Fahrenheit, degrees Cel-
sius or relative humidity.
• Relative Humidity: the output is a measurement of percent relative humidity (%RH).
• Absolute Temperature: the output is a temperature on the Celsius or Fahrenheit scale.
Scale Low
Set the electrical signal level at which the Range Low setting is the desired indicated process
value. Scale Low and Range Low are the coordinates of a point on the line that relates the
electrical signal to the conditioned process value produced by this block. Consult the hard-
ware specifications for the signal range supported by the specific hardware.
Use to set the minimum value of the process range in electrical units.
Range: -100.0 to 1000.0 VDC
-100.0 to 1000.0 mVDC
Scale High
Set the electrical signal level at which the Range High setting is the desired indicated process
value. Scale High and Range High are the coordinates of a point on the line that relates the
electrical signal to the conditioned process value produced by this block. Consult the hard-
ware specifications for the signal range supported by the specific hardware.
Use to set maximum value of the process range in electrical units.
Range: -100.0 to 1000.0 VDC
-100.0 to 1000.0 mVDC
