NOTE:
The three-stage standby battery charger is always “On”. Whenever AC power is
present at the AC Input Hot 1 terminal, the charger will charge the batteries
connected to the battery positive and battery negative terminals. The On/Off
switch has no effect upon the charger.
2. LED Indicator
All Legend Series II inverter/chargers feature a tri-color LED on the front panel that will light green,
orange, or red to indicate the operating mode, battery or charger status, or an error condition.
Green:
Solid: inverter is providing AC power from the batteries
Slow Flashing: (once each second) inverter is in search mode
Fast Flashing: (four times each second) charger is charging in Float mode at 13.5 volts,
the factory setting for gel cell batteries. Float mode for liquid lead-acid batteries is 13.4 volts,
configured using the RC7 remote control. See the Three-Stage Battery Charger section on
Page 52 for a complete description of three-stage battery charging, and on Page 62, The
RC7 Remote Control section.
Orange
Solid: charger is in Bulk mode, the initial charging mode. Bulk mode for gel cell batteries is
set at the factory at 14.1 volts. Bulk mode voltage for liquid lead-acid batteries is set at 14.5
volts. Use the RC7 remote control to configure the inverter for liquid lead-acid batteries.
Flashing: charger is in Absorption charge. In Absorption stage, the charger maintains the
Bulk voltage at up to the maximum charge rate for 90 minutes.
Red
Solid: an over-current event has occurred. An over-current condition is caused by too
many loads on the unit (excessive current demand). When this occurs, the inverter/charger
instantaneously detaches from the loads. If, after a ten-second delay, the current demand
on the unit is not excessive, the unit will automatically resume inverting. If the current
demand remains excessive, the unit will shut itself off and must be manually restarted by
turning the unit Off, then On again.
