Intellitec EMS Problem

I have an Intellitec Model 800 EMS in my 50 amp coach. Lately it has been doing strange things. When plugged into 120v power the display indicates 50 amp service. When running on the genset, the display alternates between 30 amp and 50 amp and the rear AC will not run. It does not show Genset as it should.

If I pull the 5 amp fuse in the control module will it disable the system and give me full capability back?

Secondly, Intellitec does not appear to support this product well.. Is there a better EMS out there and do I really need one. The vast majority of the time I am on 50A shore power or the genset and the Ems does not load shed.

    Better: Progressive of course.. But Intelletec is usually good.

    Sometimes the computers in these computer controlled things needs a re-boot.. The manual linked to above should tell you how to do that.. Generally it is "Kill all power, 120 and 12 volt, count to five, or ten, restore power" but.. Not always.

    NO, on Intellitec, if you go to the control panel at the breaker box, and have someone connect shore or gen set, you will hear the relays CLOSE as the system powers up. If it malfunctions the system does not close the relay's. PCS systems they ARE closed and will operate shed appliances if it malfunctions. Doug

    1. Genset not reading out means that the 12 volt signal from the genset hourmeter is not being seen at the Intellitec module. Check the REMOTE quick connect at the genset for corrosion.
    2. The BAD thing about an Intellitec, IF it malfunctions, NONE of the shed relay's will close and allow those appliances to have 120 power. so, NO, pulling the fuse will not allow the Power to the Shed controlled appliances.
    3. This link will get you to the Intellitec manual and troubleshooting. Doug

    We had a similar problem with our EMS about 4 years ago on our trip to Alaska - turned out it was caused by a loose connection in the breaker panel. Once Dave checked and tightened all the breakers, the EMS has worked fine again. Intellitec tech folks pointed us in this direction when we described our phantom problem.
