As I understand it, the TM500 is in essence a "TM2020 Lite",
developed under license by Bogart Engineering for Trace. Schneider
will most likely not be able to provide support, but Ralph Heisey
probably can. You might call him with your questions. He's very
accessible, knowledgeable and helpful.<br>

<pre wrap="">Hi All,
In the past 2 months, I've had 2 separate clients with 48 volt SW systems
have their TM500 stop resetting amphours - even after there is no current
flowing into the bank for hours. The meter never goes below "0" amp hours
and always shows "Full" SOC. These are TM500s that have behaved properly
(at least in that way) for years. Anyone else ever seen this? Another
time bomb? Any fix other than replacing with a Trimetric 2020. I've seen
bizarre behavior from the TM500 before, in a 48 volt system setting up
some high frequencies which effectively shut down the C40 on the system,
but haven't seen this anomaly before these 2 systems...
Thanks,
Howie
