AC Input “High” red LED is
lit
AC input voltage is above 156 (or 299 for
230V nominal units, or 276 for 240V nominal
units, or 286V for 220V nominal units) VAC—
unit will be in Standby mode, running on bat-
tery
Measure AC input voltage with
a true RMS voltmeter. If above
156V (or 265, or 276), notify
local Power Company of the
significant overvoltage at the
power supply location. Operate
the CPR from an alternate AC
source (generator) until the
overvoltage is corrected.
AC Input “Low” red LED is
lit.
AC input voltage is below 96 (or 161 for 230v
nominal units, or 192 for 240V nominal units,
or 154V for 220V nominal units)VAC—unit
will be in Standby mode, running on battery
Measure AC input voltage with
a true RMS voltmeter. If below
96V (or 184, or192V), notify
local Power Company of the
significant undervoltage at the
power supply location. Operate
the CPR from an alternate AC
source (generator) until the
undervoltage is corrected.
Load “>100%” red LED is
lit.
CPR unit is loaded >100%. If the overload is
>110% The output will turn off after 30 sec-
onds, and then attempt to restart every 30
seconds for 3 hours. If the overload is not
removed after 3 hours, the module will shut
down and must be manually reset by press-
ing the “Output ON” button.
Reduce the overload in the
coax network.
“Inverter” red LED is lit Inverter is operating. This is normal if Utility
power has failed.
Measure AC input voltage with
a true RMS voltmeter. If power
is present, verify Utility voltage
and frequency is within the lim-
its shown above in this table.
Output voltage reads zero
or nearly zero at the front
panel test points
Coax network is shorted
Output has been disabled due to overload
timeout.
Measure AC output current
with a clamp-on probe. If it is >
rated output amps, check the
network for a short circuit, or
“bucking power” and correct.
Press “output ON” button. The
“Output Voltage” LED should
come on. Check network for
overloads.
