1.0 Introduction
The Automatic Generator Start - Standalone version (ME-AGS-S) from
Magnum Energy is designed as a standalone device. It will automatically
start your generator based on low battery voltage and/or a high temperature
condition.
Info: This manual is for the ME-AGS-S with revision 5.0 or higher;
see Figure 3-1 on page 17 for information on where to locate your
revision level.
Info: If you are using a Magnum Inverter/Charger (provided with a
network port) and a ME-RC or ME-ARC remote, use the ME-AGS-N (AGS
- Network version) for full network capability of the AGS system.
This AGS is used to continuously monitor your battery system and/or the
surrounding area temperature, and to automatically start the generator when
the battery requires charging and/or power is needed to run an air conditioner
to cool down the surrounding area.
The temperature turn-on feature is useful in many applications. For example;
if you have an RV (Recreational Vehicle) coach in a hot environment, the AGS
monitors the coach temperature and turns on the generator to power the air
conditioner. This allows you to leave pets and precious items in your coach
while you enjoy a day away golfi ng, touring, or just sightseeing - all the while
knowing your coach will stay cool and comfortable. Even if you don’t have pets,
there’s nothing better than returning to a nice cool coach while dry camping
in hot weather. Plus, no more worrying about dead batteries.
The AGS System includes a controller with on-board adjustments and inter-
faces with a user-friendly remote control switch. The controller provides the
wiring interface for the battery bank and generator start/stop circuits. It has
adjustments for setting the generator’s run time, high temperature start, and
low battery voltage start; and if needed, the “Clock” and “Quiet Time” adjust-
ments can be set to comply with RV park and rest area nighttime low noise
requirements. The remote switch allows testing and activating the AGS system
and provides a LED indicator to display AGS system status information.
This AGS is compatible with most AC or DC generators with either two-wire or
three-wire start controls; such as Onan, Power Tech, Generac, Martin, Kohler,
Honda, Westerbeke, Yamaha, and many others. A list of generators that have
been successfully used with the AGS along with their respective wiring dia-
grams can be found at www.magnumenergy.com/GenWiringDiagrams.htm
