Watlow F4T • 209 • Chapter 5 Function Reference
TC Linearization
Select the Thermocouple type.
Options: B, K, C, N, D, R, E, S, F, T, J
Display Precision
Set how many decimal places are displayed for the process value and associated parameters
such as set points.
Options: Whole, Tenths, Hundredths, Thousandths
Calibration Offset
Set a value to add to the measured input value to compensate for sensor placement, lead
wire resistance or other factors that cause the input to vary from the actual process value
Range: -99,999.000 to 99,999.000°F or units
-55,555 to 55,555°C
Filter
Set the amount of filtering to apply to the input.
Filtering smooths signal fluctuations. Increase the
time to increase filtering. Excessive filtering slows
the input’s response.
Range: 0.0 to 60.0 second
Input Error Latching
Set whether an input error persists until it is cleared or clears automatically when the sensor
signal returns to a normal level.
Options:
• Off: error clears automatically once the input returns to normal.
• On: error remains active until the input returns to normal and the error is cleared by
the Clear Error parameter.
Clear Error
Set this parameter to Clear to reset the input error after correcting the condition that caused
it.
Options: Ignore, Clear
Milliamps
These FBs are found on the canvas of the FB diagram. The number of these FBs that are avail-
able depends on the number of flex modules with Universal Inputs installed and configured for
milliamps.
The module number shown on the FB is the number of the controller’s slot that houses the
flex module with the Universal Input. The Universal Input number indicates the specific input
on the flex module.
