A TRUE RMS voltmeter is required for accurate AC output voltage readings on
quasi-sine inverters. Other voltmeters that use averaging circuitry will give a
false reading.
•
The LCD Remote Control/Status Panel “Read Panel” Red LED warning indicator will
light to indicate a problem either with the inverter or battery charger. Press the
“Panel – On/Off” button to turn the display ON.
•
A problem with the transfer relay is indicated when it fails to switch between battery
power “inverter mode” and “external power mode” or when appliances do not
operate when the inverter is in “external power mode”.
•
Unplug all loads and connect a 100-watt light bulb to the inverter output. Observe
the LCD Remote Control/Status Panel then check the troubleshooting table.

MESSAGE
PROBLEM
POSSIBLE CAUSE
1
The SPS is not connected to
the batteries or the battery
voltage is below 9 volts DC.
Check the in-line fuses for continuity.
Make sure the DC wires are clean
and tight. Check the DC voltage at
the inverter DC input.
2
Indicates immediately that the
SPS is operating in a low
battery voltage condition.
Fault in the battery wiring, battery
capacity and voltage or the in-line
fuse. This message will automatically
clear or the screen will go to
message 3.
3
Indicates that the inverter has
shut off due to a low battery
condition. Press the
“inverter &
reset – On/Off”
button three
times to turn the inverter back
ON.
The same screen message coming
on again indicates a fault in the
battery wiring, battery capacity and
voltage or the in-line fuse. If the
condition persists, call Dimensions.
4
Indicates immediately that the
SPS is operating in an overload
condition.
SPS output wiring is shorting or
loads that exceed rating. This
message will automatically clear or
the screen will go to message 5.
