Application example for an energy counter output
1. Connect the digital output to an external counter.
2. Configure the digital output using the display unit or PICUS to
Active energy export pulse 1
.
3. Configure the
Pulse every
parameter to the value where you would like to send a pulse. For example, 100 kWh.
4. Configure the
Pulse length
to the required length of the pulse for your external counter. For example, 1 second.
With the example setup the controller sends a 1 second pulse to the external counter for each 100 kWh the controller logs.
