The Environmental Module Environment Screen
Select <ENV> 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.
