NV5/NV3.5 Troubleshooting Manual Responding to alarms
Issue 3.2 2014-12-10 Page 1-25
2. Attempt to reset the alarm by resetting one of the defaulted parameters to its desired value or
state. Even if no parameter requires resetting, it is necessary to re-write at least one
parameter. Press Apply in the applicable AUI screen.
3. Cycle the ac power (switch off ac power, then switch back on).
4. If the Controller: EEP Fail alarm persists, suspect the control/interface PWB (A1) and if
necessary, replace it (see “Control/interface PWB replacement” on page 1-39).
RF Power Module faults
There are many alarms on the AUI, prefixed by the text Module, that indicate faults related to one or
more of the RF power modules. The number that appears after Module (1-2) 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 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 1-
26.
2. If the forward power reading in Step 1 is normal press the Transmitter Status button on the
AUI to check for other alarms that may have triggered the RF power module alarm.
3. From the AUI’s System Review page, click the i (information) button to view the RF
Modules status screen (see Figure 1.2 on page 1-26). This screen displays critical parameters
for both2 RF power modules. As an aid in troubleshooting, compare parameters to isolate
possible module faults.
