IMPORTANT SAFETY INSTRUCTIONS

This manual contains important safety instructions that should be followed during the installation and maintenance of this product.

To reduce the risk of electrical shock, and to ensure the safe installation and operation of this product, the following safety symbols have been placed throughout this manual to indicate dangerous conditions and important safety instructions.

WARNING - A dangerous voltage or condition exists in this area.

Use extreme caution when performing these tasks.

AVERTISSEMENT - Une tension ou condition dangereuse existe dans

cette zone. Faire preuve dextrême prudence lors de la réalisation de

ces tâches.

CAUTION - This procedure is critical to the safe installation or

operation of the unit. Follow these instructions closely.

ATTENTION - Cette procédure est essentielle à linstallation ou

lutilisation de lunité en toute sécurité. Suivre ces instructions de

près.

NOTE - This statement is important. Follow instructions closely.

NOTE - Cette déclaration est importante. Suivre les instructions de

près.

 All electrical work must be done in accordance with local, national,

and/or international electrical codes.

 Before installing or using this device, read all instructions and cautionary

markings located in (or on) the VO-DPM, the manual, the batteries, the inverter, etc.

 Do not expose this unit to rain, snow or liquids of any type. This product is

designed only for indoor mounting.

 To reduce the chance of short-circuits when installing or working with the

inverter or the batteries, use insulated tools.

 Remove all jewelry such as rings, bracelets, necklaces, etc., while

installing this system. This will greatly reduce the chance of accidental exposure to live circuits.

 The inverter contains more than one live circuit (batteries and AC). Power

may be present at more than one source.

 This product contains no user-serviceable parts. Do not attempt to repair

this unit.

BATTERY SAFETY INFORMATION

 Always wear eye protection, such as safety glasses, when working with

batteries.

 Remove all loose jewelry before working with batteries.

 Never work alone. Have someone assist you with the installation or be

close enough to come to your aid when working with batteries.

 NEVER smoke in the vicinity of a battery or generator.

 Always connect the batteries first, then connect the cables to the inverter

via a DC disconnect switched OFF. This will greatly reduce the chance of spark in the vicinity of the batteries.

 Use insulated tools when working with batteries.

 When connecting batteries, always verify proper voltage and polarity.

 Do not short-circuit battery cables. Fire or explosion can occur.

 In the event of exposure to battery electrolyte, wash the area with soap

and water. If acid enters the eyes, flood them with running cold water for at least 15 minutes and get immediate medical attention.

1.0 INTRODUCTION

The VO-DMP Features

The Vesta Online-Digital Power Monitor (VO-DPM) features six data

monitoring functions and two indicators including:

 State of charge/amp-hour content (full or percent of capacity)

 State of charge/voltage (real-time voltage level, historical high and low

system voltage)

 Low Battery indicator

 Full-charge indicator

 Real-time power meter of load and charge

The unit is configurable for specific system or application functions such as setting the CHARGED indication parameters, battery capacity, charging efficiency, low-battery warning conditions. The VO-DPM can monitor any battery supply from approximately 8 to 65volts, track energy consumption and estimate remaining battery life.

In addition to its status monitoring features, the unit can act as a remote control, switching the inverter OFF or ON (only on DR inverters).

The VO-DPM operates on 12-, 24-, or 48-volt battery systems.

NOTE: If the remote control feature is desired in the PDC, the RC8 remote in the Power Module must be disconnected. This feature is only applicable of DR inverters.

The VO-DPM

2.0 CONFIGURATION

Setup

The VO-DPM is configured at the factory for monitoring a 24 VDC system. These settings can be changed to meet specific system parameters.

The default settings are:

Charge Efficiency 94 %

Voltage (full-charge) 28.8 volts DC

Amperage DC 35 amps

Amp Hours 400 Hours

Low-Voltage Indicator 22.0 volts DC

Restoring the Factory Defaults

The factory defaults can be restored to their original settings if desired. The default values will return to those listed above and are for a 24 VDC system.

To restore the factory defaults:

1. Set the VO-DPM into the power saving mode by repeatedly pressing

the SELECT button until the LED display goes blank.

2. Press and hold the RESET button. The display will indicate ALL

flashing in the display. Continue to hold the RESET button until the LED display remains blank.

The factory defaults are now restored.

Step 2 = ALL then blank

2.0 CONFIGURATION

Setting Parameters

Individual system parameters can be set by the following procedure:

1. Press the SELECT button until the mode selection indicator to be set is

illuminated.

2. Press the SELECT and RESET buttons simulataniously. Release both

buttons when the LED display flashes.

3. Press and release the RESET button to scroll through the selections (or

values) slowly, or hold the RESET button to scroll rapidly.

4. When the desired value is shown in the LED display, press the SELECT

button to accept it.

Charge Efficiency

Since batteries are not 100 percent efficient, more energy is required to charge them than can be extracted. Some of this energy is lost in the form of heat and gassing. An efficiency factor of 94 to 98% is typical for lead-acid batteries. Consult the battery manufacturers specifications for other batterytypes.

Set this value to 96% for new batteries and 94% (or lower) for batteries already in service. The default setting is 94%. Changing this setting affects the % State-of-Charge meter. The setting range is from 60 to 100%.

Setting the Charge Efficiency Factor

If the charge efficiency factor is not known and lead-acid batteries are used in the system, set the charge efficiency factor to 94%. After the batteries have been discharged and then fully recharged, the battery level reading should be approximately full. If this reading is less than full when the CHARGED LED ( ) flashes, increase the efficiency factor. If the battery level is full before the CHARGED LED flashes, decrease the efficiency factor. The setting is correct when the CHARGED LED flashes and the battery level% is full.

1. Press the SELECT button until the BATTERY LEVEL LED (%) is

illuminated.

2. Press the SELECT and RESET buttons simulataniously until the LED

display flashes.

3. Press the RESET button to change the displayed efficiency factor.

4. Press the SELECT button to accept the value.
