Activate Rectifier Modules

Activate TMA Channels (2 per Sector)

CAUTION: This parameter sources +12 V at 500 mA maximum to antenna ports. Caution should be used

if antenna ports are connected to test equipment with 0 VDC tolerance.

To prevent a short circuit and alarm situation, all antenna port connections must be complete prior to

enabling TMA DC supplies.

NOTE: These configurations enable DC voltage at antenna ports and enable RX fault monitoring.

Each Rx channel sources +12 V at 500 mA maximum. Any current less than 40mA will generate a LO

CURRENT fault. Any current greater than 150mA will generate a HI Current fault. Any current greater than

500 mA will disable the DC source for that channel and generate a HI CURRENT fault.

A HI CURRENT condition attempts to auto-recover every five minutes by enabling the DC to Rx channel. If

fault condition is cured, alarm clears and source remains on. If fault is present, there is no change in sta-

tus.

Table 3-4 Activate Rectifier Modules

Step Action

1 Select the System/Configuration Page. See Figure 3-15.

2 Using the pull-down menus in the Rectifier/Installed section, choose YES to activate the

Rectifier Modules. Reference the rectifier positions detailed on the front rack ears of the

power system. Default is NO.

3 Choose SUBMIT to accept and apply the changes. To abort changes choose another page

without applying submit.

Table 3-5 Activate TMA Channels

Step Action

1 Select the System/Configuration Page. See Figure 3-15.

2 Using the pull-down menus in the TMA Main/Diversity sections choose ENABLE for the

TMAs to be utilized. Default is DISABLED

3 Choose SUBMIT to accept and apply the changes. To abort changes choose another page

without applying submit.

4 Navigate to the Status / Dynamic page. See Figure 3-17.

5 Verify the correct TMA channels have the correct current draw per the specifications of the

TMA. Currents less than 40mA or greater than 150mA will assert a fault. Currents greater

than 450mA will crowbar the power source. The system will retry every 5-minutes to enable

the channel in the event the short is remedied. A crowbar can also be reset by configuring

the channel disabled and then enabled.

OS-1933-E3-003 Troubleshooting Troubleshooting Status of each individual module can be determined by the status of the LED (MCPAs, Rectifier, Controller represents system and RFCUs). All LEDs should illuminate a solid green; any other indication requires access to the Status / Alarm page. Some common alarms and there remedies are detailed in the following sections.

Troubleshooting OS-1933-E3-003 Rectifier Module with a Red LED or Individual Faults – Any rectifier module fault is remedied by replacing a known good module with the suspected unit. Refer to the Status/Alarm page for exact details. Reference the Rectifier Module section in Chapter 2 for the procedure on Rectifier Module replacement. RECT ALL COMM Fault Could to the result of a bad RJ45 interface cable at the rear of the system linking the controller with the power system.
