Err
Code
Description Possible Cause Things to Check Correction
384 POST HVDC to
30V failed- supply
too low
The HVPS output is too
low during POST.
Cycle system power and deter-
mine if this error is repeated.
Watch LED2 on the HVPS dur-
ing POST and confirm that it
illuminates. If not, disconnect
the cable between the HVPS and
the RF Amplifier and cycle while
again watching LED2. If it is
now illuminated, a problem with
the RF Amplifier is likely.
Configure system for test mode
operation. Verify HVPS control
signals from the controller are
correct while activated.
Verify the HVPS is function-
ing correctly – see HVPS
Troubleshooting Guidelines
Verify that all cables
are properly con-
nected.
Replace the
Controller assembly.
Replace or repair the
HVPS.
Replace or repair the
RF Amplifier.
