Ready/Fault relay
The Ready/Fault relay is a potential free relay toggle for READY or FAULT indication. This
allows the amplifier to notify an external device or indicator that the amplifier status is either
"RDY" (all is ok) or "FLT" (fault) and may not be functioning correctly. The next table explains
the relay setting for the different operation and error modes.
