CAUTION
Do not modify Parameters P5 to P18 during power calculations. Improper
power calculations may result.
Using the Sliding Window algorithm, parameter modifications are introduced into the
calculations when a sample occurs (every tenth of Parameter P10). Using the other
two algorithms, Ideal Curve and Extrapolation, the parameter modifications are
introduced into the calculation at the beginning of a measurement interval (after
receiving a synchronization pulse).
After one or more parameters (P5 to P18) have been modified, Parameter P8
must be set to 1. This tells the calculation algorithm that parameters have been
modified to include them in a coordinated manner. When the time arrives to include
the modifications, the calculation algorithm writes the value 2 to Parameter P8,
registers the modifications and resets P8 to 0 to show that the modified parameter
values are now in use.
Parameter P8 can be used as a Test Board parameter by setting it to 3. In this
operating mode, the maximum switch-on power value P5 is transmitted to the loads
every calculation interval (sample) until all loads are switched on. To return to the
normal operating mode, the user must reset the Parameter P8 to 0.
The following table lists the parameters used for the parameter modification at run-
time function.
