!
ATTENTION: Do not use the RPI input on the SB3000 Rectifier’s
Resolver & Drive I/O module as a method of shutting off the Rectifier.
Turning this input off stops the Rectifier’s power devices from firing.
However, the emitter-collector diodes in these power devices will still
conduct and will continue to feed the load inverter if input power is on.
Failure to observe this precaution could result in damage to, or
destruction of, the equipment.
115 VAC Auxiliary Input 1 Bit 1
The Auxiliary Input 1 bit reflects the status of
the 115 VAC auxiliary input 1 on the
Resolver & Drive I/O module in the
Rectifier’s PMI rack. When the input signal is
present, this bit is set. Hex Value: 0002H
