Suggestion
The Status LED is flashing.

document.
The Status LED is lit, but the
generator is stopped.
The AVR is powered by the DSE815 interface. This
allows configuration of the AVR when the generator is not
running.
Loss of Feedback alarm.
Check Voltage sensing connections on L1 and N(L2)
terminals.
Startup Trip alarm.
Check Voltage sensing connections on L1 and N(L2)
terminals.
Unstable voltage levels.
Check
Integral
and
Proportional
settings.
Voltage drops when load is applied.
This may be normal depending upon the settings of the
Droop
function and/or
Under Frequency Roll Off
function.
Voltage fails when load is applied.
This may be normal depending upon the settings of the
Under Frequency
alarm.
Voltage fails to reach set point.
Follow the Setup Procedure elsewhere in this manual.
Instability occurs in the voltage
output.
