Troubleshooting
During instrument warm-up, the PDM 3600 continuously monitors the
operating status for unexpected conditions. If any fault conditions are
flagged the screen will flash ‘DIAGNOSTIC FAILURE’. To view the cause
of the error, press the A and B buttons, press ‘B’ to scroll until the ‘View
Failures’ options is displayed. Press ‘A’ to view the failure(s).
The flashing DIAGNOSTIC FAILURE’ alert will stop if the condition
causing the failure is corrected before the end of the warm-up period. For
instance, ‘TE Not Present’ is most likely caused by a missing mass
transducer. Installing a mass transducer will clear this error condition.
A Programmed Shift or Primary Sample Run WILL NOT start if a
DIAGNOSTIC FAILURE is present at the end of the warm-up period.
Press ‘A’ ‘Wake up’ then ‘B’ ‘Scroll’ to identify the diagnostic failure that
prevented the shift from starting.
Below is a list of the possible diagnostic failures. See the Troubleshooting
Section of this manual for a possible cause for the condition.
