Introduction
The ME-PT1 (Pigtail one-wire) adapter is designed to be connected to the
Magnum Energy Auto Generator Start (AGS) controller to allow the connected
generator to be started when an external +12 volt DC supply is applied. This
is useful in applications where there is a requirement to conveniently and au-
tomatically turn the generator on/off externally through a manually controlled
switch or from an automatically controlled switching device.
This adapter provides one pigtail wire and when +12 volts is supplied to this
pigtail wire, causes the Magnum Auto Generator Start controller to start and
run the connected generator.
Info: The high temperature start feature on the ME-AGS is not avail-
able when using the ME-PT1. However, the low battery voltage start
feature is still available.
Installation/Setup - ME-AGS-N (Network Version)
The following pertains to the ME-PT1 when connected to the ME-AGS.
Info: Refer to the ME-AGS-N Operators Manual (64-0005) for installa-
tion, setup and operation of the ME-AGS-N; and the ME-RC Operation
Manual (64-0003) on information to select/adjust settings.
Installation
Refer to figure 2 for the following steps to install the
ME-PT1 :
1. Connect the red wire on the adapter to a +12 volt DC external switching
device (i.e. switch).
2. Plug the ME-PT1 adapter into the REMOTE (purple) port on the ME-AGS-N.
Info: The remote temperature sensor that comes with the ME-AGS-N
and is normally plugged into the REMOTE (purple) port is not used
when the ME-PT1 is connected.
Setup
When using the ME-PT1 with the ME-AGS-N, configure the ME-RC to allow the
ME-AGS-N to accept the external input from the ME-PT1 (see figure 1):
1. Press the AGS button and rotate the SELECT knob to the ‘04 Start Temp F’
menu. 2. Press the SELECT knob and rotate the SELECT knob to choose the
‘Start=Ext Input’ setting. 3. Press the SELECT knob to save this setting.

ME-PT1 Operation
The type of external switch (i.e. “maintain” or “momentary”) connected to
the ME-PT1 adapter determines how long the generator can run.
A. Using a “maintain” type switch: If the switch is off, the generator will stay
off. If the switch is on, the generator will continue to run until the switch is
turned off. After the switch is turned off, the generator will stop after the
current RUN TIME HOURS period has finished.
B. Using a “momentary” type switch: Pressing the switch will allow the gen-
erator to only run once for the RUN TIME HOURS period.
Installation/Setup - ME-AGS-S (Standalone Version)
The following pertains to the ME-PT1 when connected to the ME-AGS-S
(Standalone Version) controller.
Info: Other than the specific installation and setup instructions
listed below, refer to the ME-AGS-S Operators Manual (64-0004) for
installation, setup and operation of the ME-AGS-S.
Installation
Prepare the ME-AGS-S remote switch:
1. Find the Temperature Sensor behind the remote switch front plate; it is a
small reddish looking device close to the metal front plate (see figure 3).
2. Use a pair of small wire cutters and clip open one side the temperature
sensor (see figure 4). Ensure the cut ends are not able to touch.
Refer to figure 5 for the following steps to install the
ME-PT1 :
1. Plug a 6-conductor phone splitter into the REMOTE (purple) port on the
ME-AGS-S controller.
2. Plug the ME-PT1 pigtail into one port of the phone splitter and plug the
remote switch using its communications cable into the other port of the
phone splitter.
3. Connect the red wire on the adapter to a +12 volt DC external switching
device (i.e. switch).
