5 – PARAMETER DESCRIPTIONS

P51 Analog Output Span I/O 13

LCD Display

I/O: Aout Span

13 100 %

Range 0 – 125% (Default 100%)

Description The analog output signal can be scaled using the Analog Output Span parameter. For a 0-10V output

or 0-20mA output, a 100% scaling outputs the maximum voltage (10V) or current (20mA) when the

selected output function requests 100% output. A scale of 50% outputs 50% voltage/current when

the analog output function requests a 100% output.

NOTE: For a 4-20mA output, set the Analog Output Span to 80% and the Analog Output Offset to

20%.

NOTE: The output does not exceed 100% (10V or 20mA).

See Also Analog Output Offset parameter on page 75

Example: 0% output => 4mA, 100% output => 20ma

P52 Analog Output Offset I/O 14

LCD Display

I/O:Aout Offset

14 0 %

Range 0 – 99% (Default 0%)

Description The analog output signal can be offset using the Analog Output Offset parameter. A 50% offset

outputs a 50% output (5V in the 10V case) when 0% is commanded. If the selected variable requests

100% output, the span should be reduced to (100 minus offset) so that a 100% output request causes a

100% output voltage (x% offset + (100-x)%span)=100%.

NOTE: For a 4-20mA output, set the Analog Output Span to 80% and the Analog Output Offset to

20%.
