Reset of Billing Maximum Demands
A demand reset signals an end of the present billing period
and causes the following automatic actions:
• increments the number of the recorded billing periods.
This number will roll over to zero after 99 demand
resets;
• copies the present billing period data - maximum
demand, cumulative maximum demand and energy
values, and the number of days since last demand
reset, - to the previous billing period registers;
• adds the present maximum demand values to the
cumulative maximum demands;
• clears the number of days since last demand reset;
• clears the present maximum demand values;
• records the new previous billing period data -
maximum demand, cumulative maximum demand and
energy values, - to the monthly profile data log.
NOTE
You will not be allowed to reset the billing maximum
demands twice within one calendar day. The EM920 uses a
one-day protection lockout time to avoid subsequent demand
resets.
