7-3-6 Front End Controller (FEC) Diagnostic Tests (for RFT Configuration)
The FEC diagnostic tests include the following:
• Board Test: General board test which activates the remaining tests sequentially. Each of these
tests can also be performed individually.
• Self Test: An FEC self test generated by the DSP on the FEC board.
• BF Cache Test: Checks the access to the BF cache memory that stores the data for the focuser.
• TEE Temp Test: Checks the TEE probe temperature sensor.
• Thr Temp Test: Diagnoses the temperature threshold for TEE probes.
• Pencil ID Test: Checks the pencil ID circuit in the FEC.
Note: Before performing any of the FEC tests, perform the IMP, VME Bus and RFT tests, as
described beginning on page
7-13. If an FEC test is performed without first performing these
tests, and errors are identified, you must perform the RFT test, and then the VME Bus test and
the IMP test, to ensure that the FEC board is the source of the error.
