1. Introduction Congratulations on your purchase of the Battery Monitor, CAN Bus Node, an intelligent plug-and-play module to decentralize and expand the functionality of your Smartpack based DC power supply system.

About this Guide This booklet provides you with the required information for installing the Battery Monitor, CAN Bus Node in your Smartpack based DC power supply system. The booklet also presents the Battery Monitors technical specifications. For more detailed description of the Battery Monitor, CAN Bus Node, read the Users Guide Smartpack Monitoring and Control Unit, Art. 350003.013. For description of how to activate and configure the Battery Monitor, CAN Bus Node using the PowerSuite PC program, refer to the PowerSuite online Help system. Refer also to Installation Guide Battery Monitor Symmetry Kit, document number 351497.033, which is included with the kit.

System Diagram CAN Bus Nodes The Battery Monitor, CAN Bus Node is used as a building block in Smartpack based power supply systems, see Figure 1. Other CAN bus nodes, like the Load Monitor and the I/O Monitor, may also be connected to the bus. The nodes are powered directly from the CAN bus, and have dedicated inputs and outputs that expand the system monitoring and control capability.

The Smartpack controller monitors and controls the whole system, and serves as the local user interface between you and the system. The PowerSuite application enables you to configure and operate the system from a personal computer.

2. Battery Monitor, CAN Bus Node The Battery Monitor CAN Bus Node enables you to decentralize and increase the number of battery symmetry measurements in your Smartpack based DC power supply system. Also, it monitors the battery compartment temperature using the built-in sensor the battery fuse with a fuse monitoring input and the battery current via a current sense input.

Key Features A wide range of features are implemented in the Battery Monitor CAN Bus Node, as mentioned below:

9 Powered via the CAN bus; no external power supply required 9 Firmware upgrade via the CAN bus (see required SW Upload tools on page 14) 9 4 battery symmetry inputs

for battery strings symmetry measurements

9 1 fuse monitoring input user configurable for fuse monitoring and other site equipment monitoring

9 1 battery current sense input for bi-directional current monitoring through external current shunts

9 1 battery temperature sense input via the built-in temperature sensor

9 Storage of calibration data and real time event log 9 Windows-based setup, configuration and calibration via PowerSuite 9 Flexible mounting using Velcroue adhesive tape on the bottom of the unit 9 Up to 14 the Battery Monitor modules may be connected the CAN bus 9 CAN bus addressing via DIP switches

Read also chapter Technical Specifications, page 14, for more details.

Typical Applications The Battery Monitor CAN Bus Node is employd in Smartpack-based DC power systems, to implement flexible expansion and distribution of system functionality.

The Battery Monitor CAN Bus Node is suitable for distributed monitoring of battery symmetry, fuse, current and temperature of local and remote located battery banks.


3. Installation of Battery Monitors You can install the Battery Monitor CAN Bus Node if your DC power system meets the following requirements:

1. The systems Smartpack controller has firmware version 2.03 or higher installed 2. You have a PC with PowerSuite application version 2.3 or higher installed

You need standard installation tools and equipment used by an authorized electrician. NOTE: All tools must be insulated.

Safety Precautions Follow these precautions during installation, commissioning and general handling of the Smartpack-based power supply system.

Basis Installation Steps Carry out these steps to install the Battery Monitor CAN Bus Node in your DC power system.

Refer also to Installation Guide Battery Monitor Symmetry Kit, document number 351497.033, which is included with the kit.

Power is ON! 1. Assign the Battery Monitors CAN bus address, by

setting the Battery Monitors DIP switches. Read to chapter CAN Bus Addressing, page 12

2. Terminate the CAN bus, by e.g. removing the CAN bus termination plug from the controller and plugging it on the last connected Battery Monitor or node. Read CAN Bus Termination, page 11

3. Attach the Battery Monitor to a battery block; Read chapter Fastening the Battery Monitors, page 7

4. Connect the required input cabling to the terminals; Read chapter Connection Drawing, page 8

5. Configure the Battery Monitor nodes operation, using the PowerSuite application, read chapter About PowerSuite Configuration, page 13

CAUTION: For safety reasons, the commissioning and configuration of the equipment is only to be performed by Eltek Valeres personnel or by authorized and qualified persons; otherwise the warranty may be invalidated. Please, read the user documentation carefully before installing and using the equipment, as installation and operation is to be performed as described in it.

Qualified personnel

WARNING: The batteries represent a major energy hazard. To avoid short-circuit of battery poles, you must always remove metallic objects uninsulated tools, rings, watches, etc. from the vicinity of the batteries. Electric shock

Version Sensitive


Fastening the Battery Monitors You mount the Battery Monitor CAN Bus Node on a battery block, using the Velcroue adhesive tape on the bottom of the module. Thus, the built-in temperature sensor will monitor the battery temperature accurately.

For more exact measurements, attach the monitor on the front of a battery block. If not possible, you can fix it on the side of the outer battery block, or on top, or on the cabinets inner side wall

CAN Bus Termination To ensure a correct bus communication and avoid data reflection, you must always terminate the CAN bus with two 120 resistors, one at each end of the line (60 bus impedance).

Smartpack based systems are shipped from factory with the CAN bus already terminated with 120 resistors. The CAN bus termination is implemented with a special RJ45 plug with built-in 120 end-of-line resistor.

Figure 7 Example of CAN bus addressing and termination in a Flatpack2 system with two

Battery Monitors connected the CAN bus

When connecting Battery Monitor nodes (max. 14 nodes) to the CAN bus, you have to remove the CAN bus termination plug from the Smartpack controllers rear CAN port, and plug it on one of the CAN ports on the last connected Battery Monitor node. See chapter Removing the Smartpack Controller, page 11.

Removing the Smartpack Controller To access the CAN bus termination plug from the Smartpack controllers rear CAN port, release (1) both handle springs see Figure 8, page 11 and use both handles to cautiously pull out the module. Be careful, as cables are connected to its rear.

Configuration When connecting Battery Monitor nodes to the CAN bus of the Smartpack based DC power system, you have to configure each of the Battery Monitors by:

1. Setting the DIP switches with the correct CAN bus address, to assign a unique ID number to the Battery Monitor, read chapter CAN Bus Addressing, on page 12

2. Configuring the Battery Monitor nodes operation, using the PowerSuite application, read chapter About PowerSuite Configuration, page 13

CAN Bus Addressing The Smartpack controller dynamically software-assigns ID numbers to rectifiers. The controller registers the rectifiers ID numbers or CAN bus address (01, 02) together with their Serial Numbers.

The ID numbers (1, 230) on Smartpack controllers and Smartnode units and Battery Monitors ID numbers (33, 3446) are assigned by DIP switches on the nodes side.

A maximum of 14 Battery Monitors and or 28 controllers and Smartnode units may be connected to the CAN bus. Note that if only one Battery Monitor is connected, you have to assign it with ID# 33.

About PowerSuite Configuration

You have to connect a PC to the systems Smartpack controller and start the PowerSuite application, version 2.3 or higher, to activate and configure the Battery Monitor nodes. Read the PowerSuite applications Online Help for information on how to configure the CAN Bus nodes.

In general, the connected Battery Monitor node(s) are displayed in the PowerSuites Power Explorer pane, under the Control System node and under the Battery node. For configuring the Battery Monitor specific settings such as its software alarm monitors for fuse monitoring and current sense inputs, symmetry measurementes inputs, etc open the Battery Monitors icon under the Battery node. Open the Battery Monitors icon under the Control System node to reas the status of the Battery Monitor.
