Pulse output

4.4.6 Mean value over time window (Max. Demand)

Parameter No. 35 (max. demand) is configured here; any other parameter is 
assigned for this purpose. The selected value of this parameter is sampled at 
short time intervals within the time window, and the average value of the 
sampled values is calculated.

The mean value is a moving average formed only from the discrete values 
determined in the selected period. If, for example, a period of 60 minutes is 
selected, the mean value applies to the last 60 minutes.

Registers 1250 and 1251 define the behavior of the measuring device for the 
set value for Max. Demand: the code of the parameter to be monitored must 
be entered in register 1250. Register 1251 sets the window time in minutes.

Note:

If 31 or 48 is entered as a parameter code, the output 
will be used as a pulse output and the pulse frequency 
(Wh x pulse) will be entered in registers 1150 and 
1151.
The pulse duration for energy values is 100 ms.
