ALARM MENU
To enter ALARM menu and see the active alarms, press the enter key from the scrolling menu.
Then press the right arrow key to get past METER and then press ENTER once the ALARM
menu is visible. Once in the ALARM menu you may see an active alarm present if the heads up
LED lamp is illuminated. If no alarms are active, the display will read NO FAULTS. The following
alarms are available through the diagnostics within the Lite-Minder inverter.
Start Up Faults:
BACKFEED
This indicates that there is AC already at the output terminals
Most likely scenario is that the Lite-Minder was wired incorrectly
ROTATION
This indicates that there is a wiring fault on the transformer
Most likely scenario is that if a PCB was replaced, there was a mis-
wire when re-connecting the transformer.
OVERLOAD
This indicates that there is too much output or a short circuit load
connected.
MIS WIRE
This indicates there is lack of AC power at the input
BATT LOW
This indicates that the Batter Voltage is too low to start the unit up
Possible fault is that the battery is mis-wired, fuse is open or batteries are
dead
Faults While Lite-Minder is on Battery Charging:
AC FUSE
Indicates a blown fuse on the input AC. Fuse location is on the PCB
CHARGER
Indicates that the charger has malfunctioned
OVERLOAD
Indicates that there is too much load connected
OVERTEMP
Indicates that the FET’s Heatsink temperature has exceeded its limits
Faults While Lite-Minder is on Battery Power:
LOW VOUT
Indicates that the inverter could not produce enough voltage to
support the load
FET O C
Indicates that there was a severe overload that caused the crest factor
to be exceeded too many times and the inverter shut down to protect itself
from failure
LVD
The inverter ran on battery until the Low Voltage Disconnect point
OVERLOAD
There is too much load connected to the output
OVERTEMP
Indicates that the FET’s Heatsink temperature has exceeded its limits
