Operating Display - Trace Engineering RC7 Manual

Transformer Temperature
This meter displays the internal temperature of the inverter/charger's transformer. The
scale is divided into counts, which do not directly correspond to the Fahrenheit or Celsius
temperature scale. A higher reading indicates a lower temperature. This meter is useful to
service technicians only.
FET Temperature
Displays the relative temperature of the Field Effect Transistors, which regulate the output
waveform of the inverter. A higher reading indicates cooler temperatures. This meter is
useful to factory technicians only.
Estimated Battery Capacity
This meter reports the estimated battery amp-hour capacity based upon the average amp-
hours used, and the rate and duration of the charging cycles. Multiply the reading by eight
to arrive at the approximate battery capacity. This is only an approximation, and it will
become more accurate as the number of charge/discharge cycles increase.

Operating Display

Upon installation of the RC7 or RC7GS, the LCD screen will display general-purpose
system-status messages. This is the screen that you return to upon exiting the Setup,
Settings, or Meters menu. These operating messages monitor the battery state-of charge
(SOC), time remaining to run, and time left to charge. It also provides the Gen Start/Stop
switch. B y pressing the Down arrow key, y
sequence in which they are discussed below .
Battery State of Charge
This meter displays the estimated State-of-Charge (SOC) of the battery or battery bank.
The state of charge is based upon the estimated battery capacity. Because it is damaging
to most batteries to discharge them to less than half of their capacity, this meter estimates
the battery SOC at 0% when the battery amphours remaining has reached half of the
estimated battery capacity. This prevents over-discharging and potential damage to the
batteries.
