TAC 20 Strange Issue - 05/27/20 08:14 PM
Hello all,
I'm the System Administrator for an elevator service company.
We've taken on a job with a TAC 20, which seems to have a few problems. There was a bit of a frayed traveling cable which has since recently been replaced. However, the elevator cab continues to stop sporadically upon reaching the fourth floor. The technician has checked and ensured there are no problems with the placement of the encoder strip, as well as the hoistway magnets.
From IMS we can see that a 1086 and 1030 error are being thrown. The technician has already reset the CPU as well as having downloaded the backup copy of NV memory via IMS. Here’s where my, as well as the technician’s thinking, comes into play. If there is corrupt memory then wouldn’t IMS have downloaded a corrupted “backup” copy of that memory, only to re-download that back to the CPU when using the Service>Transfer>Download from IMS option?
We have obtained the files from a floppy disk that we were hoping would have files we could put into a folder in IMS and perform that same Download from IMS option, but it looks to no avail. The floppy disk contains 5 files with the following file names.
The files located on the floppy don’t appear to correlate with any backup files which are currently located on our IMS laptop under the IMS directory, even looking in the directory that houses the most recently modified files pertaining to this particular job don’t have any sort of match either by file name or file size.
My sincerest apologies for the long-winded nature of this post, however, I’m at somewhat of a loss as of what to suggest to my technician and this one has him scratching his head. A bit of added background, every time this elevator has stopped, which was a lot more frequently before the traveling cable was recently replaced, the owner (this is located at a hotel) would simply reset the main power in order to get the elevator back into operation. So turning everything off and on again seemed to limp it back into service, however coming from a technical background and looking at this from that standpoint, my postulation is that if you want corrupted memory, that’s a great way to get corrupted files/memory, cut power to a thing while it’s thinking and then turn it back on again.
Anyhoo if anyone has any ideas or suggestions as to where to go from here please drop a comment below, it would be much appreciated! Thanks all!
