OPERATION
The following is a description of the status LED's locat ed on the front panel and the internal fan.
AC Present
When the AC Mains is present, the LED will illuminate. If a power failure was long in duration, or the
AC mains was disconnected by some other means (Circuit breaker open) the AC Present LED would
not be illuminated. When the control circuit senses that th e line has dropped below an acceptable
level (Black Out, Brown Out, or Transient), the inver ter will energize for at least one minute. So, if the
power failure was a momentary glitch, the AC present LED would be illuminated but the inverter
would be running.
System Ready
When the system has adequate battery voltage to transfer, the System Ready LED will illuminate.
This feature prevents damage from multiple deep dischar ges of the battery.
Battery Charging
When the AC Mains is connected to the line and the batter y is charging under normal conditions, the
Battery Charging LED will illuminate.
Battery Power
When the inverter is producing output power (battery is be ing discharged), the Battery Power LED will
be illuminated.
Fault
This is a summary Fault indication. When there is a fault condition present, the Fault LED will
illuminate. To view which fault is present, use the k eypad and LCD display feature.
The front panel display will provide the user with a variety of information. It has a full compliment of
Meter functions, Control functions and Program func tions.
Fan
The fan operates during emergency mode and only during nor mal mode when the batteries are being
charged. When the batteries reach float condition (trick le charge) the fan turns off.
