AGS settings - a lot to know

Just got off the phone with Newmar and as usual they were very helpful. I was curious as to why my AutoGen did not kick in when my coach wasn't plugged in last time and the batteries went completely dead.

Here are the setting Newmar recommends (silverleaf)

Go to AutoGen tab on Silverleaf

Page 1
Safety lock - CLEAR (this is the most important step - more about this later)
Auto Charger - Enabled
Exerciser - Disabled (unless you want to run generator weekly)
Auto Temp - Enabled (if you want generator to kick on once coach gets to a certain temp)

Page 2
Autocharger start volts - 12.1
Autocharger Max Run Time - 240 min
Topoff volts - 12.6V
Topoff Run Time - 90 min

Page 3
Quiet time begin 8:00am
Quiet time end 8:00am (these are the same because you want the generator to kick in ANY time - you can change them, but it wont work during quiet hours)
Chassis start volts - 12.7V
Charge bridge duration - 60 min

Page 4 (only pertains if you have exerciser function enabled)
Exerciser day of week - any
Start time - any
Run time - at least 30 mins

Page 5
Auto temp set point (78 - can set at whatever you want)
Auto temp delay time - 1 min
Auto temp deadband 2F

These were recommended by Newmar. Your needs/wants may vary. I will say almost none of mine were set correctly.

Here's two very important points..

If you start the generator manually at any time AND/OR if you open the front generator compartment for any reason, the "safety lock" kicks in and MUST BE CLEARED in order for AGS to be active. If the safety lock is on, the AGS is not. This was my issue.

So, the rule of thumb that was suggested was every time you leave the coach, go to the "genset" button (the one in the left column, not the one in the middle column - that will start the generator), and hit the "clear AGS" button, verify that the AGS message is "Standing By", and you are good to go.

So glad I called on this. I was completely clueless.

This is very useful information. Thanks.

However, I do wonder about one of the settings. You show "Chassis Start Volts" as 12.7V. The manual says "Sets the DC Voltage Value that will automatically start the generator from low chassis battery voltage", which is what I would think it means. My interpretation is that it would start the generator when the chassis voltage is below this value, so 12.7V seems high? Mine was set at 12.3V, and during factory pickup we saw the AGS starting because of this (batteries were fine), so lowered to 12.0V.

I was wondering about that myself after I got off the phone with them. If it becomes a problem I will lower it.
