Fluorescent Lights & Power Supplies
Some devices cannot be detected when scanned by Load Sense circuitry.
Small fluorescent lights are the most common example. Some computers
and sophisticated electronics have power supplies that do not present a
load until line voltage is available. When this occurs, each unit waits for
the other to begin. To drive these loads, either a small companion load
like a light bulb rated for more than the load sense setting must be used to
bring the inverter out of its search mode, or the inverter may be
programmed to remain on by disabling the Load Sense feature. (See
“Load Sense” on page 3–19.)
Clocks
You may notice that your clocks may not be accurate. Some of the clocks
on your appliances may reset when the inverter/charger is in load sense
mode.
Searching
When the inverter is in Load Sense (search) mode, it may fail to start
some loads even though the rated wattage on the load is more than the
load sense setting. Apply an additional load (companion load) to make the
inverter exit Load Sense mode.
