System Start-up Check
To test the charging and inverting functions from the MS2000 front panel:
1. Disconnect AC power from MS2000 AC input by opening the breaker or
disconnect. Press the Inverter Enable button on the MS2000. The Inverter On
light illuminates.
2. Place a load on the inverter. For example, plug a 100 watt light bulb into an
outlet that the inverter is powering and make sure it works. The inverter
should run the load using battery power.
3. To test the charger, recon nect the AC input power to the AC input. The
Charger On light should illuminate after a brief delay. Any AC loads
previously powered by the inverter will also work at this time.
4. Remove the AC input power. The inverter/charger should transfer to invert
mode immediately. (The transfer relay will make a clicking sound and the
Inverter On light will illuminate.) Loads should continue to operate
uninterrupted.
To test the transfer switch:
1. If the inverter is enabled, press the Inverter Enable button on the unit to
disable the inverter function. The Inverter On light is not illuminated.
2. Apply qualified AC power to the MS2000 input. After a brief delay, the
External AC light should illuminate and AC loads on the output should
operate.
If any part of this procedure fails, determine the cause before using the
inverter/charger. Consult the “Troubleshooting” chapter starting on page4–1.
To test the Echo Charger:
1. Check the System screen on the System Control Panel and ensure the
MS2000 is in the Bulk or Absorption charge cycle.
2. From the MS2000 advanced menu on the System Control Panel, verify that
the Echo Charger is enabled.
3. If the Echo Charger is enabled, verify that the MS2000 advanced menu is
displaying the Echo Charger current and voltage.
The current displayed will depend on the voltage level of the house bank and the
voltage difference between the house battery bank and the engine battery.
