[RE-wrenches] GSCM-mini with Honda EM5000SX

Mon Mar 25 10:16:34 PDT 2013

when i have seen this (battery post melting) in the past it was from a faulty (high resistance) battery connection... usually a poorly crimped lug.

Larry,

Thanks for your reply. For some reason the  schematic I received from the tech at Atkinson did not show any wires being  connected to pins 9 & 10 and as I'm a literalist I did not make those  connections. After I received your (and other) feedback I connected gen power to  those pins and the AGS seemed to function fine. Within 2 days the customer  called me back saying his genny was shutting off after 20 mins of runtime. I  told him to disconnect or reprogram one system component at a time to find the  fault source. Before a fault source was determined, he observed that two  batteries in his bank were experiencing the "battery terminals melting into the  battery casing" (as was texted to me by the customer). I have no idea how a GSCM  interface would cause or allow an overcurrent fault at the batteries but the  timing of the installation seems to indicate that the AGS is at fault. Ever  heard of this before?

I've    installed a GSCM-mini (interfaced with a Honda EM500SX w/manual remote    start box) according to the attached schematic provided by Mr. Kendall of    Atkinson. The unit is not functioning properly. It seems that the GSCM-mini is    not recognizing that the generator is running.

Here are the results of    my troubleshooting:

Start LED (yellow) on GSCM-mini blinks once every 5    seconds to indicate it is ready.

When starting the generator using the    MATE3 from either the manual Generator Status Menu, or using the auto 2    minute Voltage Start - 
Generator starts OK, MATE enters    RUN mode, no faults listed on MATE, AC IN shows USE AGS, i.e., everything    looks OK. But when I press the OFF button on the Gen Status screen the STATUS    goes to OFF but the generator will not shut off...until...

At the time    of manual start the GSCM begins going through the cycle of trying to start the    genny then goes into a Lockout Fault Condition:
Start LED goes to solid    yellow, K1 light comes on, generator starts, K1 light goes off for 40 seconds,    yellow Start light is solid, K1 comes back on for 20 seconds, cycle repeats 3    times, K2 light comes on for 5 seconds, Gen Hz LED Fault blinks twice    repeatedly, Fault LED (terminal 12) comes on solid, GSCM enters (Max Crank)    Lockout Fault, ...then the generator shuts off.

Seems the GSCM is not    registering a Valid Run Condition. So, either the schematic for the 4000SX is    not applicable for the 5000SX or the red wire I connected to terminal 8 (as    shown in the schematic, needs to actually go to terminals 9&10, or I need    to run a wire from the Pilot LED on the manual remote start box to terminal 8    on the GSCM...

Any    experience with this scenario?

Thanksalot,

We install solar pool pumps quite frequently here in the      Caribbean. We use Sunpumps - excellent company, great support. Email Joe      Lines joe@[mailto:joe at sunpumps.com] sunpumps.com for design assistance, he is very      helpful.

A few questions. 

I have a customer who        really wants a solar-direct pool pump for his home. Medium size in-ground        pool and I'd like the pump to be strong enough to lift to the solar pool        panels (12 ft lift above pool level). I'd like to offer him hardware that        is at least one notch above experimental beta-test. I remember the        SunCentric from several years ago, but not sure how durable that turned        out, and I was having trouble a vendor for it now. Any suggestions for        today with some favorable track record? Or suggestions on what to        avoid?
