Parameter values 9, 10 and 14...17 use the formula in the following table.
Value setting
C + B
C value + (B value - 50% of reference value)
C * B
C value · (B value / 50% of reference value)
C - B
(C value + 50% of reference value) - B value
C / B
(C value · 50% of reference value) / B value
Where:
• C = Main reference value
( =

Example:
The figure shows the reference source curves for value
settings 9, 10 and 14...17, where:
• C = 25%.
• P 4012
SETPOINT MIN
• P 4013
SETPOINT MAX
• B varies along the horizontal axis.
