Opt 61 getting daily minor alarms - code is NPR 0504 and this relates to incorrect use of Conf should use Ld 34 or Ld 46. Conf Loops seem ok, but any advice would be useful
NPR0504 is normal response on Conf loops when you STAT in LD 32. You will also receive NPR0301 on the digital loops. This is not an error on your equipment. Just information directing you to LD 34 for more conference loop information and LD 60 for digital loops.
The good thing about LD 32 STAT is a quick check on all loops.
just general system status.
and the NPR0504 is one of the constant reports the system generates. Do I need to do anything about it ?
there are others and I know that they relate to old extns with vm but the extns have either been ceased or the number of vm messages exceeds the current max.
Just doing a STAT in LD 32 doesn't prove much or give a real look at what is happening. Unless I think I have a LOOP down and I'm not sure which LOOP is is, that is the only time I would do a STAT. If you really look at the STAT you will see somethings that don't actually exist in the switch, and it's been that way for 20 years. If you STAT the individual LOOPS you would get better info.
Why change the engine if all you need is to change the spark plugs.
