2.5.3 Gen 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 (and possibly violating the generator’s warranty).
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 (does not provide any voltage or current) and operate only as
switches that turn on and off low amperage devices. 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 confi 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 information and to view diagrams on connecting
the AGS to the start/stop circuit on many generators, refer to the
“Generator Wiring Diagrams” section at www.magnumenergy.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 and RY2) for 3-wire generators; or all three relays (RY1, RY2,
RY3) for generators that require an independent bypass or preheat circuit.
The connection points to each relay is as follows (see Figure 2-7):
• Relay 1 (RY1) and Relay 2 (RY2)
Terminal #5: This is the Normally Open (N.O.) position of the RY1 relay.
Terminal #6: This is the Common (COM) position of both Relay 1 (RY1) and
Relay 2 (RY2).
Terminal #7: This is the Normally Open (N.O.) position of Relay 2 (RY2).
• Relay 3 (RY3)
Terminal #1: This is the Normally Open (N.O.) position of Relay 3 (RY3).
Terminal #8: This is the Common (COM) position of Relay 3 (RY3).
