cause the data to be invalid. The Purge Nozzle Assemblies need not be
removed during each maintenance; however, Teledyne Monitor Labs
recommends that the transducers be visually inspected approximately

9.2 TROUBLESHOOTING GUIDE
One of the design features of the Ultraflow 150 system is that all of the
information necessary to troubleshoot the system to a subassembly level
can be obtained from the Enhanced Remote Panel. The Status Codes
together with the Service Data Values will define almost any system
problem.
If a Fault is indicated or you suspect a problem:

Go to the Enhanced Remote Panel and write down the status word and
Service Data values.

Decode the status word according to the help screen or tables of
section four. This alone may point to the problem.

Compare the Service Data readings to the readings from your last
maintenance check sheet.
If at this point the problem is not apparent:

Go through the maintenance check sheet procedure (Appendix B).

Review this data for the proper ranges and compare it to those of
previous maintenance.
If at this point you have not been able to determine the problem:

Call the Teledyne Monitor Labs tech support line (800) 846-6062. A
factory trained technician with years of experience will handle your
call. Please have available:
