Start/Stop Connections (Terminals 1, 5, 6, 7, & 8)
This section details the control relays inside the AGS controller
and provides information on wiring these relays to the generator’s
start/stop circuit. You must identify the generator’s start and stop
wiring requirements to determine how many relays you require, the
amount of wires you connect, and in what combination.
If the generator is equipped with a remote control terminal or
connector, the connections to the AGS control relays are made much
easier if the generator‘s optional remote control panel is purchased.
Connecting to the generator’s remote panel also eliminates the need
to make connections inside the generator.
The AGS controller provides three control relays (RY1, RY2, and
RY3) to operate the autostart/autostop functions of your generator.
These relays are dry contacts (provides no voltage or current) and
operate only as switches that turn low amperage devices on/off.
They are not intended to directly provide power to starter motors or
ignition systems. Rather, they are used to send a signal to operate
the coil of another higher amperage device, which does the actual
switching of power.
CAUTION:
A fuse rated at 5 amps or less must be used to
protect each of the relays.
The warranty does not cover
damage to these relays.
Fuses should be located as close
as possible to the generator connection. A fuse must be
used even if the circuit is providing only a “dry contact” or
“ground” connection—it will prevent damage if the connection
is miswired or damaged.
Info:
To set the generator type—which determines the
operation of the AGS relays—see “GEN TYPE Setting” in the
Setup section.
Info:
Due to the different generator types and the various
starting/stopping wiring con
fi
gurations used by generator
manufacturers, detailed wiring instructions are not provided
in this manual. Please refer back to your generator’s
documentation for wiring details.
Info:
For more info and to view diagrams on connecting the
AGS to the start/stop circuit on many generators, refer to our
website at www.Magnum-Dimensions.com.
Depending on your generator’s start and stop wiring requirements,
you may only need to use one relay (RY1) for fully automatic two-
wire generators; two relays (RY1 & RY2) for 3-wire generators;
or all three relays (RY1, RY2, RY3) for generators that require an
independent bypass or preheat circuit.
