The PCS100 AVC-20 has experienced a fault condition, the bypass
circuit will shunt the inverter side of the injection transformer,
bypassing the inverter and effectively providing a direct utility
supply to the output, without interruption to the load.
This is a latched condition and the PCS100 AVC-20 will remain in
FAULT with the bypass closed until reset by the operator.
Refer to Section 9 for a description of the fault codes.
The control electronics are on. The power electronics are off.
Examples of Auto Bypass conditions include low utility voltage and
over-temperature or over-current conditions.
Status "FAULT" will show on the display, along with the current
fault code. The fault will also be reported as an event in the
system event log.
Examples of Fault conditions include inverter transistor de-
saturation, sustained over-temperature or over-current conditions,
communications lost between modules in the system.
Some Fault conditions such as de-saturation conditions cannot be
reset until after a cooling period has expired.
The PCS100 AVC-20 is transitioning from BYPASS or AUTO BYPASS
to RUN i.e. as the result of user start command or recovery from
some AUTO BYPASS conditions.
STARTING for a period of time until all conditions have cleared and
then complete the transition to RUN.
The PCS100 AVC-20 is transitioning from RUN to BYPASS or AUTO
BYPASS i.e., as the result of user stop command, or an external
event causing some auto bypass condition.
