Do not block the ventilation ports, and ensure the equipment isoperated within the temperature and humidity ranges described in this manual.2

General Description3. General DescriptionThe Albér BVM-40 Battery Voltage Monitor helps ensure that jars used in battery backupsystems will perform when needed. The BVM continually reads the voltages of up to 40 jars thateach have a nominal voltage of 12VDC. An easily readable, backlit LCD (liquid crystal display)screen indicates each jar voltage, minimum, maximum and average jar voltage, and overall stringvoltage.Two front panel push buttons are used to light the LCD screen, view readings, set up the unit, andcalibrate the unit when necessary. The buttons are either pressed independently or together toenable the various functions. The light on the LCD goes off after about one minute. Pressing theup or down button turns the light back on.The power switch is on the rear panel. The BVM may be left powered on continuously with noadverse effects.3.1. DefinitionsJar – The container that holds a cell or group of cells. In this manual, the term jar refers toone 12 volt battery consisting of six cells.Cell – The basic electrochemical unit that delivers electrical energy. Common usage permitsthe use of the word battery when referring to a cell, although it is technically incorrect. Thenominal voltage of a cell is 2 volts.Battery – Two or more cells (or jars) connected together electrically.3

Installing the BVM5. Installing the BVMThis section describes how to mount the BVM, install the voltage sense leads, and terminate thewires at the BVM and jar ends. The BVM-40 system consists of the BVM-40 unit and cables thatconnect the unit to the jars being monitored. Refer to the system drawings and verify allcomponents are available before starting installation.WARNING: Do not energize the BVM or any component with 115VAC or battery voltage untilafter the installation is complete.The maximum length for each voltage sense lead is 100 feet (≈30.5 meters) from BVM to jar.Consider this length and locate the BVM reasonably close to the jars (batteries). Mount the BVMto allow for front and rear panel access. You will need the following tools (or equivalents) tomount and connect the BVM:• Panduit CT-260 crimper for terminals.• Flat blade and Phillips screwdrivers for BVM connectors and mounting hardware.• Drill and 7/32" (0.218") drill bit.5.1. Mounting the BVMNormally, mount the BVM directly to the outside top or inside top of the battery cabinet.Four threaded mounting holes on the BVM top and bottom allow mounting from either side.Refer to drawing BDS-363-A572 for typical installation.If you are securing the BVM to the inside top of the cabinet, use the four standoffs providedto ensure adequate ventilation through the top cover. A template drawing (included) identifieswhere to drill the holes in the battery cabinet. Using the template, drill the holes using a 7/32"(0.218") drill bit, remove any burrs from the drilled holes, and mount the unit with thesupplied screws (and standoffs if required).WARNING: The four mounting screws must not hit the internal components in the BVM-40.Do not substitute the four screws supplied (#10-32x3/8"). The screws must not go more than3/8" into the unit. The supplied screws will provide sufficient holding strength for mountingthe BVM-40 to surfaces up to 1/8" thick.After mounting, ensure the ventilation holes on the top of the BVM are not blocked.5

Installing the BVM5.2. Voltage Sense Lead Harness RoutingThe installer normally determines the wire routing. If the BVM is not located directly on or inthe battery cabinet, do not route the wires in the same conduit as other wires in the facility.Use a Panduit (or equivalent) insulated, slotted cable tray with cover to distribute wires to thejars. Suggested cable trays and covers are Panduit E1X1L66 with C1L66, or E5X5L66 withC5L66. When installing the tray along the length of each battery tier, make sure the tray doesnot interfere with jar replacement and the jars remain accessible for servicing afterinstallation.If the BVM is located on or in the battery cabinet, a cable tray is not needed. Neatly tie wrapthe wires in bundles, with appropriate service lengths available.5.3. Voltage Sense Lead ConnectionsThe supplied wiring harness is for batteries with up to 40 jars. Some batteries will have fewerthan 40 jars, and all the sense leads will not be needed. In this case, you should remove anddiscard the extra leads (see below).Route each sense lead from the BVM to the jar and cut to length. Before connecting to thejar, install a tab washer or "C" clamp on the battery for making connection; refer to drawingBDS-1165-A568 for details. Also, you must install a current limiting resistor (supplied) at theend of each lead nearest the battery; refer to BDS-120-A373. Use drawing BDS-2268-B946for identifying harness assemblies and locating sense leads.If the battery has fewer than 40 jars, connect the lead that would normally connect to thepositive post of the next jar to the negative post of the last jar. For example, if the battery has32 jars, connect the lead that normally connects to jar 33 positive to the negative post of jar32. Albér recommends you remove the connector cover and cut off and discard any unusedharness leads.6
