Echo Charger Operation
For the built-in Echo Charger to operate, both the Echo Charger and the main
charger must be set to Enabled. By default, the Echo Charger is enabled by the
MS2000 to charge an engine battery 10 seconds after the main
charger has entered
Bulk or Absorption mode, and the house battery voltage is at 13.2 volts DC or
higher. The Echo Charger’s maximum charge current is 10 amps.
The Echo Charger stops charging under the following conditions:
• the maximum charge time of 8 hours is up.
• the current to the engine battery is less than 1 amp for more than 3 minutes.
• the engine battery voltage is equal to or greater than the house battery voltage.
Operation of the Echo Charger is shut down when:
• the MS2000 exits Absorption mode. The Echo Charger does not operate when
the main charger is in Float or Equalize mode.
• you disable it from the System Control Panel.
• it reaches a fault condition. See “Fault Messages” on page 4–9.
See “Echo Charger Specifications” on page A–4 for more information.
