3.6.4 Registration period
The registration period is the period of time used to calculate demand val-
ues (and energy increment values). At the end of a registration period, the
current value of the maximum demand registers will be stored. Subse-
quently the maximum demand registers will be set to zero. Two independ-
ent registration periods can be defined:
•
Registration period Tm1:
"Billing registration period" programmable in steps of 1, 2, 3, 4, 5, 6, 10, 12,
15, 20, 30 and 60 minutes.
•
Registration period Tm2:
programmable in steps of 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60 minutes
as well as 2, 3, 6, 12 and 24 hours; if not required, this registration period
can be disabled;
registration period Tm2 can be programmed to the same value as Tm1.
Calculation of maximum demand values and billing data (see page 25) only
takes place for registration period Tm1.
