PDM3700 Instruction Manual
Thermo Fisher Scientific
During instrument warm-up, the PDM3700 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 fault, press the A and B buttons, press ‘B’ to scroll until the
‘View Failures’ options is displayed. Press ‘A’ to view the failure(s).
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 along with the associated
WinPDM Instrument Diagnostic.
