996PSP PIPE SIMULATOR CHART (Metric)
NOTE: When using a 996PS-4 Simulator, you must access the [Application Data] menu,
select [Liquid Type] - [Other], then program the [Estimated Vs] for a value of
2100 m/s.
6. Access the [Pick/Install Xdcr] menu. Access the [Transducer Model] menu cell. Enter the
Transducer Model option list. Select [991 Universal].
7. Check the [Transducer Size] menu cell. If necessary, enter the Transducer Size option
list and pick the actual transducer under test.
8. Check the [Xdcr Mount Mode] menu cell. Adjust as necessary to match the simulator
chart above.
9. Move the highlight down to [Install Completed?]. Access the option list. Move the cursor
to [Install]. Press <ENT> to start the transducer install routine.
10. Check to make sure that the flow computer returns the Number Index listed in the chart
above. Next, review and verify the Diagnostics data items as described previously. If the
computer, cables and transducers are operating properly, then review all site conditions
to locate the operating problem.
If a Pipe Simulator/Test- Block Test Fails:
1. Replace the transducer cables. If this allows you to complete the test as described above,
then the cables were defective.
2. If the cables are proven to be good, replace the transducers on the pipe simulator with a
“known good” set. If the system functions properly, then the original transducers under
test are defective. Please return any defective transducers to Controlotron for repair.
3. If you replace the transducers and cables, and the system still fails to function correctly,
then it is likely that the computer has a malfunctioning circuit module. If you have spare
modules you may try module substitution to identify the defective module. Otherwise,
please call Controlotron’s Technical Service Department for further instructions.
