<div dir="ltr"><div>Hey Allan,</div><div>I don't know about the wiring of the on/off switch - I'm not sure it is simple logic. I do believe it worked for the trace SW, not sure about the DR.</div><div>I wouldn't recommend using the TM500 - I ran into a significant problem with it when used with an SW and a C40 back some 17 years ago, which eventually led me to stop using Xantrex equipment due to the either ignorance or withholding of info by their tech support about this issue. I remember talking to Ralph who said he had strongly recommended to Xantrex to not split his logic board the way they did, putting part of it onto the shunt, because he thought it might cause communication issues, which in my case it did. Long story which I believe I posted here many years ago, but it was a major pain. I have used TM500s many times successfully, although they seemed vulnerable to surge damage. I don't think I've heard any equipment conflicts with it and non-Xantrex equipment, I just have a visceral reaction to using them. Sorry for the diversion...<br></div><div>Howie<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, May 10, 2020 at 8:25 PM Sindelar Solar <<a href="mailto:Allan@sindelarsolar.com">Allan@sindelarsolar.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>Esteemed Wrenches, graybeard (used here as a gender-neutral term)
contingent:</p>
<p> I am putting together a low-cost off grid upgrade package for my
nearest neighbor out here, who has lived with a most basic system
with little upgrade since the 80s. She needs a sinewave inverter
to run a modern washing machine. I'm using good older equipment
left over from other upgrades: an early narrow FX E-Panel, Outback
VFX3524, ProStar 30, circuit breakers (!), etc. <br>
</p>
<p>I have a 'Trace Meter Battery Monitoring System' that I'd like to
include for her. It's basically a TriMetric variant that Trace
purchased the rights to modify and private label from Ralph at
Bogart Engineering about 15-20 years ago. I can easily find the
installation and operations manual online. But unlike the
TriMetric, Trace removed the terminal screw strip on the monitor
PCB, replacing it with two RJ6 connectors and a plug-in phone
cable. A matching connector was included with the meter that
mounted to the kelvin terminals on the 500A/50mv shunt.<br>
</p>
<p>I have a (believed to be) working monitor and a bunch of 6-pole
RJ6 cables (they were also used to parallel DRs for 120/240, and
maybe other tasks as well) but not the matching shunt board. Does
anyone know, or can tell me how to determine, which RJ6 terminals
are which? The TM2020 on which this meter was based had 4: G1, G2,
SIG and +. Also, the monitor also has a second RJ6 terminal for
serving as an on/off switch for (probably) the DR. Do you know
which terminals are used for this remote switch function, and
whether it could also serve as an on/off switch on the inverter by
connecting to the remote switch terminals on the VFX (this works
with a standard on/off switch in place of the Mate, so it oughtta
also work with this switch function, no?).</p>
<p>Thank you for any assistance you may provide.</p>
