[RE-wrenches] GSCM-mini with Honda EM5000SX

Mon Mar 25 09:15:14 PDT 2013

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?

  You need the line and neutral from the generator connected to pin 9 & 10 or the GSCM does not know if the generator is running or not.

  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 at 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?
