Standard Splitter Output (STD SPLITTER)

This function can be used for heat/cool applications. It is a deadband-based splitter that divides a Split
loop’s output (-100% to +100%) into two outputs CVn A1 and CVn A2, both of which are zero when the
loop output is zero (Figure 4-14). A deadband provides a range of loop output within which both split
outputs remain at zero. For overlapped outputs, use Advanced Splitter. Note: A third output CVnA3 is
displayed Online and should be ignored.

Prompt

Range/Selections

Definition

RANGE LOW

RANGE HIGH

OFF or number

Enter the output’s display limits. Output is not clamped or
flashed when it exceeds these limits.

INPUT

OFF, analog parameter,
number

Input source. Typically, this is the output value (OV) of a
Split Output type of loop.

FEEDBACK #1

AOn BC, LPn BC, CVn BC

Enter an AO, LP or CV for the back calculation value (BC)
of the analog output assigned to the A1 output.

FEEDBACK #2

AOn BC, LPn BC, CVn BC

Enter an AO, LP or CV for the back calculation value (BC)
of the analog output assigned to the A2 output.

OUTPUT

DEADBAND

OFF or number

Deadband up to 10% of the input span. In this range, both
split outputs will remain at zero.
