2.4.9.
Energy pulses
The terminal can be configured to send a pulse whenever
certain amount of energy has been imported or exported. The
basic idea is presented in Figure 2.4.9-1. Each time the energy
level reaches the pulse size, an output relay is activated and
the relay will be active as long as defined by a pulse duration
setting.
Figure 2.4.9-1. Principle of energy pulses
The manager 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
thirteen output relays. The connection is configured in the
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.
