The
can be programmed in
order to operate in 4 different integration
modes:
1 - Synchronised with the utility
maximeter, through synchronism pulses
that are given in each period initiation
(
).
2 - Synchronised with the utility
maximeter, by means of synchronism
pulse. (
). From this
pulse, the equipment calculates the starts
and ends of each period based in an
internal clock. When a new pulse is
received, it will be re-adjusted and it will be
synchronised again.( It is recommended
to receive one synchronism pulse each 24
hours.)
3 - Without synchronism with the utility
maximeter, using a sliding window
(
).
4 - Without synchronism with the
maximeter, using a sliding window and
simulating the response of the thermal
exponential function of the mechanical
meters (
).

Following the graph you can observe
the behaviour of the device in the 4
operation modes, for an integration period
of 5 minutes.
For synchronised operation mode (
block demand pulse and block demand
time ) and Rolling (sliding window) the
device will reach up to the maximum value
of the demand, in this case 36 kW, at the
end of the integration period (5 minutes).
For
operation mode, the
will get up to 90% of the
maximum demand value at the 5 minutes,
and up to 99,9 % at 10 minutes.
