The page breaks & formatting, as well as start & end sections, of this online variant of the ATevo Communications Module Instructions may differ slightly compared to the paper hard copy included in your battery charger manual pocket. For an Adobe PDF digital copy of that manual, access the following link (JA0102-54).

BEFORE YOU START

  • Familiarize yourself with ALL SAFETY Instructions.

1.1 Overview

ATevo Communications provides users remote access to battery charger controls (user input) and charger status (ATevo output) normally accessed at the battery charger’s front panel display.

This can be done in 2 ways:

  1. By using either DNP3 Level 2 or Modbus SCADA communication protocols with either a Serial Communications Adapter or Ethernet Communications Adapter installed, all charger controls and charger status can be accessed.
    • Serial Communications Adapters (A12), supporting BAUD rates from 9600 to 115.2K for:
      • 3-wire or 5-wire RS-232 connections
      • 2-wire or 4-wire RS-485 connections
    • Ethernet Communications Adapter (A22), supporting standard RJ-45 10/100 Mbps copper Ethernet connections
  1. By using the Web Server remote graphical interface option available starting with Firmware v3.3.0 with an Ethernet Communications Adapter installed, current charger parameter settings can be seen and adjusted. Charger status, such as current Float Voltage output is not available.
    • Ethernet Communications Adapter (A22), supporting standard RJ-45 10/100 Mbps copper Ethernet connections

1.2 Forced Load Sharing

The ATevo Forced Load Sharing option similarly utilizes a Serial Communications Adapter (A13). For detailed information on Forced Load Sharing, refer to instructions (JA5054-50), or Section 13 of the main ATevo ‘battery charger’ Operating & Service Instructions manuals (JA0102-51, JA0102-52, or JA0102-53).

1.3 ATevo Set Points & Firmware Defaults

Certain entries in the DNP (Section 5) & Modbus (Section 6) points tables are dependent on ATevo battery charger model. Ranges differ, depending on nominal output voltage (24, 48, 130, or 260 Vdc).
For a complete listing of these settings, download the latest revision of the ATevo Set Points & Firmware Defaults (JA5124-02).
