3.9.
Energy pulse outputs
The device can be configured to send a pulse whenever certain
amount of energy has been imported or exported. The principle
is presented in Figure 3.9-1. Each time the energy level reaches
the pulse size, an output relay is activated and it will stay
active as long as defined by a pulse duration setting.
Figure 3.9-1. Principle of energy pulses
The device has four energy pulse outputs. The output channels
are:
Active exported energy
Reactive exported energy
Active imported energy
Reactive imported energy
Each channel can be connected to any combination of the
output relays using output matrix. The parameters for the
energy pulses can be found in the E menu under the submenus
E-PULSE SIZES and E-PULSE DURATION.
