The battery symbol is normally white with associated lines in white. The
battery becomes green when emergency power is on. Battery voltage with the
current load is shown in white next to the battery. The voltage turns amber
and boxed, when out of limits. When emergency power is on, the battery load
(amps) is shown next to the battery in white. If no valid data is available, the
data will be removed and replaced with an amber X.
10. Transformer Rectifiers (TR)
Transformer rectifiers are normally shown in green but become amber when
the TR fails. TR voltage and load digits are shown next to the TR symbol in
white. If no valid voltage or load data is available, the associated data will be
removed from the screen and replaced with an amber X.
