Advanced Energy

Error E081 Fault Vector

The Master/Slave fault vector associated with error code E081 E81 contains three hex bytes,
separated into one two-byte word and a one-byte word (see Command 135 of the AE Bus
command list). The two-byte word is a bit-wise "or" of all the slave unit errors; thus if a bit is
set, the error exists in one or more slaves.
Note: If your Pinnacle master unit features an active panel, you can view error code
information for each slave by turning the MODIFY knob.)
The one-byte word describes the faults in the communication bus between the master and
slaves.
The three hex bytes are displayed in this order from left to right: slave status high byte, slave
status low byte, personality card status byte. The bit definitions of these bytes are as follows:
