CONFIGURATION

4.3. DEMAND

To access the maximum demand control parameters conguration screen, position the cursor

over DEMAND and conrm by pressing SET.

Parameters that can be congured on this screen follow:

Period: Integration window minutes used calculating the maximum demand. Values can

be programmed from 1 up to a maximum of 60.

Win. type: It is possible to select between two window types to calculate the maximum

demand. These are:

• FIXED: Each period duration initializes the maximum demand value. If

programmed for 15 minutes, the measured values are integrated every

15 minutes, and the values for the next 15 minutes are set to zero.

• MOVING: The beginning and end of the integration period moves with each sample

collected. The calculation for maximum demand is made with the

values, in the integration time, each time a new sample is recorded.

To store the modied parameters in memory, press SET and conrm with OK (F4). To exit without

saving changes press ESC (F3).

Another example of event are showed in times period t1, t3 and t4. They are Sags. They are

congured usually unther 90% of the nominal voltage.

When the voltage goes down unther 10% it is stored as an interruption. That interruption is

showed in period t2.

Thre quality events has to be longer than 10ms. If the duration is less than 10ms, the event will

not be stored but will affect to the calculus of the average value for that period.
