Energy pulse outputs
Figure 12: Energy impulse outputs
The type of energy impulses is selected in section “6.5.1.- ENERGY ACCUMULATION MODE”.
If option 4q is selected, the device generates:
Impulse output 1 (terminals 47 and 48): Active energy impulses consumed (positive).
Impulse output 2 (terminals 49 and 50): Active energy impulses generated (negative).
If option 2tis selected, the device generates:
Impulse output 1 (terminals 47 and 48): Active energy impulses consumed (positive) in tariff 1.
Impulse output 2 (terminals 49 and 50): Active energy impulses consumed (positive) in tariff 2.
The impulse output ratio is set to 5000 imp /kWh, that is, when the device accumulates an energy of
1 kWh, 5000 impulses exit the impulse output.
We have to consider that in relation to this ratio the energy is calculated by the device, taking into
account the programmed voltage and current transformation ratios.
Thus, the actual energy can be calculated as:
