The LCD displays two lines of twenty characters. Two types
of messages are displayed: system status or measurement.
A system status message is the default at turn-on, after a
system failure or stop sequence.
Each line consists of three columns that identify: 1) power
source, 2) source mode, 3) source status.
Power source
definitions are as follows: "INV." refers to the inverter module.
"BYP" refers to the bypass mechanism, either maintenance
bypass relay or static transfer switch.
For definitions of source mode and source status messages,
as well as corresponding LED status indicator colors, refer to
Table 1-2 .
