In the MKV IODOS computer, the auto calibrate page is not displaying the voltage feedbacks from the LVDTs of IGV, and in the SRV and GCV calibration pages the LVDT2 of the SRV is coming to the LVDT1 of the GCV.

When checked in the DiagC the LVDT's feedbacks are showing correctly, it looks like there is only some problems in the configuration in the display pages of IGV and GCV.

Is there any way to correct this anomaly in the display screens of the autocalibrate page?

Thanks in advance,

Brian

 

<p>The file F:\UNIT1\ACALIB.DAT is the file that defines how the AutoCalibrate displays are configured; it sounds as if some "editing" has been done.

<p>Here is an *EXAMPLE* of SRV, GCV, and IGV sections from a working ACALIB.DAT file.

<p>Be careful when editing any file; and again, make a backup before editing any file, to be able to easily get back to a known state (even if it's known to be an undesirable state; sometimes it's better than nothing!).

Let us know if this is helpful. It's *NOT* recommended to copy these sections to ACALIB.DAT; they are just provided as examples to compare
against the existing file to see if there are any glaring discrepancies. Any information on a line after a semicolon ( ; ) is treated as a comment and is ignored.

 

Thanks once again for your prompt reply, will come back after testing the above procedure.

Thanks,

Brian
