Voltage Calibration
Calibrate the input to the expected usable range of the sensor driving the input. The Inputs response to the
application will be scaled between the Min and Max voltages and return 0% to 100% (0 – 1023) to the
application.
Min: The minimum voltage.
Range: 0 to 4.99v must be less than Center and/or Max Volts
Center: The center voltage.
Range: .01 to 4.99v must be between Min and Max Volts
Max: The maximum voltage.
Range: .01 to 5.00v must be greater than Center and/or Min Volts
Voltage Limits
These values are used by the system to sense an out of bounds voltage condition at the input. The Voltage
Limits may be used to detect an open or shorted input wire or overdrive condition. These conditions are
normally due to faulty wiring. The condition is communicated to the program using the Name.MinF and
Name.MaxF variable names where Name is the name you gave to the input like Ana_1.
Min: If the input voltage is less than this set point, Then “Name.MinF” is set to true.
Range: 0 to 4.99v
Note: If the voltage goes out of range, the user must reset Name.MinF variable through application code to
false.
Max: If the input voltage is more than this set point, Then “Name.MaxF” is set to true.
Range: .01 to 5.00v
Note: If the voltage goes out of range, the user must reset Name.MinF variable through application code to
false.
Max Current
These values are used by the Programming tool to keep track of the total current expected to be used by the
Reference Output. The user may enter the expected current draw for the sensor being used if the sensor is
driven by the Reference Output. If the sum total of all the entered currents from all the Analog and Universal
Inputs exceeds 500mA, a warning will be displayed.
Using Ref. Voltage: If selected, the Max Current entered will be added to the total expected load for the
Reference Output.
Range: Selected / De-Selected
Max Currnet: The amount of current that is expected to be drawn by the sensor used on this input.
Range: 0 - 500mA
Invert Output
When Invert Output is checked, the returned percentage values of the voltage range will be 0 for MAX Volts and
100% for MIN Volts.
Range: Checked/Unchecked
