DIGITEL Newel 3 User manual

  • Hello! I've reviewed the user manual for the N43 Energy Meter. This document provides details on how to configure the meter, connect it to communication buses, and how to use it to measure network parameters and analyze energy consumption. It also covers the usage of an impulse counter. I'm ready to assist with any questions you may have about the device described in this document.
  • What communication parameters must be set for the N43 counter?
    What is the minimum impulse length for the impulse counter?
    What parameters of the network are measured by N43 Energy Meter?

11. ENERGY METERING
11.1. ENERGY COUNTER N43
Energy metering can be performed using the N43 meters. They must be connected to one of the
communication buses according to the diagram below. They measure all important parameters of the network.
These values, recorded in the central unit, allow a detailed analysis of the consumption, creation of statistics,
estimation of the operating costs etc ...
The communication parameters of the N43 counter must be programmed as follows:
[Adr] - 1 à 31 (address - value between 1 and 31 unique for each module)
[trb] - r8n1
[bAU] - 19.2k
