Integral deadband supervision
The deadband value used in the integral calculation is configured with the
X deadband
setting. The value represents the percentage of the difference between the maximum and
minimum limit in the units of 0.001 percent x seconds.
The reporting delay of the integral algorithms in seconds is calculated with the formula:
