The Environmental Module Environment Screen
Select on the Environmental Module Specific Screen, as shown in
Figure 3-28, to access the Environmental Module Environment Screen, as shown
in Figure 3-29. This screen displays voltage, temperature, and non-condensing
humidity readings for the Environmental Module.
Line 1 displays the measured values for the 48 volt DC power bus and the 3.3 volt
bus for the Internal Network Bus (INB) terminator modules. The MMAC-Plus
power supply system provides these voltages as input to the Environmental
Module. The acceptable limits for the 48 volt line are between 40 and 59 volts. The
acceptable limits for the 3.3 volt line are between 3.1 and 5 volts.
Line 2 displays the temperature of the Environmental Module in Fahrenheit and
Celsius. The temperature is qualified as either COLD, COOL, NORM (normal),
WARM, or HOT based on system parameters.
Line 3 displays the Environmental Module’s non-condensing humidity level as
STATIC RISK, NORM (normal) or MOIST, based on system parameters.
