RF Power Module Faults
There are many alarms on the AUI (local or remote) or controller UI, prefixed by the text
RF Module
,
that indicate faults related to one or more of the RF power modules. The number that appears after
RF Module
(1-4) identifies the position of the affected module. Numbers correspond to modules in a
left to right, top to bottom sequence, as viewed from the front of the transmitter.
1. Check the forward power reading on the UI or AUI. If it is less than the preset level, one or more RF
power modules are defective. Proceed to
“RF Power Module Fault Validation” on page 4.1.36 .
2. If the forward power reading in Step 1 is normal, go to the controller UI’s
Alarms
screen or select
the AUI’s (local or remote)
Status
button on the remote AUI to check for other alarms that may
have triggered the RF power module alarm.
3. From the remote AUI’s
Meter List View
page (see Figure 4.1.7 ), click the
i
(information) button
next to the RF Modules # folder in the Transmitter Layout section to view the status screen for all
modules or click the right-hand arrow to expand the RF Modules folder to allow clicking on the
i
button for an individual RF Module (e.g., RF Module 1, see Figure 4.1.8 on page 4.1.35 ). This screen
displays critical parameters for all four RF power modules. As an aid in troubleshooting, compare
parameters to isolate possible module faults.
