9C300-1 Environmental Module Operation

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.
