2002 with AGS

Is the AGS wired to the AC on my 2002 Alpine? While i sort out the other AC issues, i might as well make sure that works.

I assume you have the old Xantrex AGS ... it should work with the AC. You simply set the "AGS" on the Duo-Therm Control to "On". The "AGS" is like a 3rd zone on the control. If the AC needs to come on it will start the generator and as soon as the generator takes the load the AC should come on.

The only time I tested this function I could not determine a "graceful" means of shutting it down. I turned off the AC but the generator kept running. I shut the generator off manually and then had a red error light come on. I called Xantrex who explained how to pull the large connector off the AGS system (in a cabinet) , wait about 30 - seconds, and then plugged it back on. OF course, the time reference for setting "Quiet Time" is off but that's another story.

can anyone tell me how the AGS is wired to A/C? I'm not getting it to start when the a/c's call for power. It works fine with the battery...

my usage for the generator would be greatly reduced if the AGS worked with the a/c.

Assume you are talking 5-button t-stat--if so, then Bob Bs. explanation is pretty close. AGS, ACs and t-stat are all connected via phone cable. T-stat needs to have the AGS "zone" set to on, and the AGS control panel has to be set to the correct time of day and the quiet-time option set accordingly. You didnt mention either of these in your 2 nd request for help??????

Aaron,

If you pull out the large plug from the AGS System (typically located in the cabinet next to the monitor/control cabinet) you'll find that the cable is actually quite long. If you have problems pulling the cable out, temporarily pull off the monitor panel to reach in to help guide the cable out thru the opening.

There is a flexible sleeve on the cable that can be temporarily removed to expose the wires. The wires are actually labeled via printing for their function. The leads you're looking for are "Thermostat #1 (+)" and Thermostat #1,3 (Common)". These leads show up on pins #6 (Orange) & #14 (White) respectively. The "Thermostat" function on the AGS is a "Normally Open" situation. The "+" lead will have 12V (or close to it) and the "Common" lead will have ground when the thermostat requires the generator to run. Refer to the AGS manual for a pin configuration and orientation of this cable

Make sure you have 12V to the tank monitor panel (same power source). Make sure you don't have any "Quiet" settings enabled on the AGS control. Make sure the AC will come on when shore power is applied. Make sure that the AGS "Zone" in the DuoTherm is set to "On". Remove or disconnect shore power. Remember, that there is approximately 2 - minute delay before the AC unit(s) actually come on after the DuoTherm control has been turned on and set.

I recently converted my old AGS to the Xanbus AGS product which is why I know about the leads. I did NOT trace the "Thermostat" leads back to the DuoTherm because it wasn't necessary once all functions were successfully tested. I would imagine you could remove the DuoTherm control to test the AGS related leads.

I guess what i'm looking at. Neither A/C has the gen/start switch toggled (which assuming is correct), but i don't see the AGS zone on the CCC, which leads me to believe that there is some issue with what's connected to the AGS.

Where does the connection from the AGS system to the A/C occur, from the rear phone line hook ups? There are two phone lines to the rear A/C, neither are hooked up. there is one at the front a/c, which appears to be a second cable from teh front to the back.

I will look into the cabinet behind the panels and see what's there and go through Bob's list

Aaron,

Yes, there is a telephone cable involved. Inside the monitor/control cabinet you'll find what appears to be a metal junction box. The telephone cable plugs into that metal box. In fact, I had problems when converting to the new Zanbus AGS and discovered that the cable had come disconnected from the box.

I believe the junction box serves to help separate the house battery voltage from the chassis battery voltage where the AGS remote control is concerned. I know that without that phone cable connected, the AGS remote control does not work. This is evident by the fact that "Off" light isn't even on.

thanks guys! Found it. one of the telephone wires in the back that wasn't hooked up was for the AGS. I found it reset the CCC and the AGS zone came up and worked perfect!!!!
