INTRODUCING THE TRACE BATTERY STATUS MONITOR
The Trace Meter battery status monitor features six data-monitoring functions and three
indicators including:
State of Charge/Amp-hour content: full or percent of capacity
State of Charge/Voltage: real-time voltage level, historical high & low system
voltage
Amps: real-time amps, total charging amps, total load amps
Amp-hours removed
Days since fully charged
Cumulative amp-hours
Recharge indicator
Low voltage indicator
Full charge indicator
The Trace Meter works with 12-volt, 24-volt, and 48-volt battery systems (optional TM48
shunt board required for 48-volt systems).

  • Page 2: Basic Operating Functions

    BASIC OPERATING FUNCTIONS The Trace Meter enables you to monitor battery state-of-charge, voltage, amps, and amp- hours used. You can configure the reporting functions of the Trace Meter to your specific application by setting the fully-charged criteria, battery capacity, charging efficiency, low- battery warning conditions, and recharge reminder.
  • Page 3: Hookup Procedure

    Hookup Procedure Mount the Deltec shunt on or near the battery box near the negative (-) battery terminal or DC supply. The shunt is installed in the negative DC supply circuit. Disconnect the negative battery cable at the battery or battery bank and attach it to the side of the shunt labeled ‘Inverter’.
  • Page 4: Basic Meters

    To complete the installation, insert the shunt communications cable into the RJ6 telephone- type connector on the back of the Trace Meter printed circuit board (PCB). There are two RJ6 connectors on the back of the PCB. The one near the top left of the board is the shunt connector.

    % (Percent State of Charge) When this indicator is lighted, the LED screen will display the battery state-of-charge based upon the amp-hour capacity. Range is LO setting(<27.5%), 30% to 90% in 5% increments, and ‘FULL’ when over 92.5% of capacity. V (Volts) When this indicator is lighted, the LED screen will display the real time voltage from 08.0 to 35.0 volts (12 and 24 volt system) with...
  • Page 6 Reminders and Other Indicators The Trace Meter features a programmable recharge reminder, low-voltage indicator, and a charged indicator. Recharge Reminder You can configure the Ah lamp to flash at a specified interval following recharge as a reminder that it is time to charge the batteries. The range is from one to 99 days, or you can turn it Off.
  • Page 7: Setting Parameters

    SETUP The TraceMeter is factory-configured for monitoring a 12-volt DC system. You can configure the Trace Meter for your specific application. Reset to Factory Default Values You can reset program values instantly by pressing and holding the Reset button when the Trace Meter is in Power Saving mode.
  • Page 8 Setting the efficiency factor: If you do not know what efficiency factor to use, if you have lead-acid batteries start with 94%. If you find that after discharging and recharging your batteries that the amp-hours reading is somewhat below 000 (negative) when the Charged LED flashes (charge settings reached), then increase the efficiency factor.
  • Page 9 RESET RESET SELECT SELECT SELECT Voltage Alone: To specify voltage as the sole criterion, set the fully-charged voltage value first and then turn the amps criterion Off. Press Select to select the amps (A) indicator and enter the Setup menu by pressing the Reset button while holding the Select button down.
  • Page 10: Limited 2 Year Warranty

    RESET RESET SELECT SELECT SELECT Other considerations: The type of charger (relay, taper, or three-stage) may also influence these criteria. A relay type charger charges up to a set voltage and shuts Off, using only voltage as the criterion. Adjust the voltage-only criterion slightly below your charger turn-off voltage and disable the other criteria.
  • Page 11: Warranty Procedure

    WarrantyProcedure Complete the warranty card and mail it to Trace Engineering within ten (10) days from the date of purchase. Keep your bill of sale as proof of purchase, should any difficulties arise concerning the registration of the warranty card. Warranty registration is tracked by model and serial numbers only, not by owner's name.

  • Page 14 TechNote 5: Battery Voltage and Current Why does the voltage on a discharged battery measure the same as a fully charged battery, until loads are applied? The simple answer to this might go as follows: A battery creates electrical power by converting energy from a chemical reaction into electrical energy.
  • Page 15 Measuring Battery Condition with the Battery At Rest. A good estimate of a battery's state of charge can be made by measuring the voltage across the battery terminals with the battery at rest (No energy input, no energy output) for at least three hours.
