Problem Loads
Very Small Loads If the power consumed by a device is less
than the 25-watt threshold of the power save
mode circuitry, and power save mode is
enabled, the Freedom XC will not run. Most
likely the solution will be to disable power
save mode.
Fluorescent
Lights and Power
Supplies Some devices cannot be detected when load
sensing. 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 25 W
must be used to bring the Freedom XC out of
power save mode, or the Freedom XC may
be programmed to remain on by disabling
power save mode.
Clocks You may notice that your clocks are not
accurate. Some of the clocks on your
appliances may reset when the Freedom XC
is in power save mode.
When the Freedom XC is in power save mode, it may fail to start
some loads even though the rated wattage on the load is more
than 25 W. If these kinds of loads are in the system, follow the
suggestions given to eliminate the problem.
If the problem loads cannot be eliminated, there are two work-
around solutions:
1. Disable power save mode from Settings on page 56 ,
causing the Freedom XC to always remain at full output
voltage.
2. Use a search-friendly companion load whose only purpose
is to be switched on to wake up the Freedom XC to power
the load that is unable to bring the Freedom XC out of power
save mode.
NOTES :
n
Power save mode, by function, cannot work with clocks
and timers or devices that need power 24 hours a day.
Examples of devices with timers include cable TV boxes,
coffee makers with brew timers, refrigerators, and freezers
with defrost timers. Examples of devices that need power
24 hours a day include telephone answering machines,
alarm systems, motion detection lights, and some
thermostats.
n
When the Freedom XC is load sensing the output for loads,
lights that have a wattage lower than 25-watt threshold,
may flash momentarily.
