2.5.3 Gen Start/Stop Connections (Terminals 1, 5, 6, 7, & 8)
This section covers the control relays inside the AGS module, and provides
information about wiring these relays to the generator’s start/stop circuit.
You must identify the generator’s start and stop wiring requirements in
order to determine: how many relays you require, the number of wires you
connect, and in what combination.
When the generator is equipped with a remote control terminal or connector,
it is much easier to make the connections to the AGS control relays if
the generator‘s optional remote control is purchased. Connecting to the
generator’s remote also eliminates the need to make connections inside the
generator (and possibly violating the generator’s warranty).
The AGS module provides three control relays (RY1, RY2, and RY3) to
operate the autostart/autostop functions of your generator. These relays are
dry contacts (they do not provide any voltage or current), and operate only
as switches that turn low amperage devices (≤5 amps) on and off. They
are not intended to directly provide power to starter motors or to ignition
systems. Rather, the relays 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 the Gen Type setting info in Section 3.1.
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 to your generator’s documentation for wiring details.
Info: For more information, and to view diagrams on connect-
ing the AGS to the start/stop circuit on many generators, go to

Depending on your generator’s start and stop wiring requirements, you may
only need to use one relay (RY1) for fully automatic 2-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 are as follows (see Figure 2-11):
• Relay 1 (RY1) and Relay 2 (RY2)
Terminal #5: the Normally Open (N.O.) position of the RY1 relay
Terminal #6: the Common (COM) position of both Relay 1 (RY1) and
Relay 2 (RY2)
Terminal #7: the Normally Open (N.O.) position of Relay 2 (RY2)
• Relay 3 (RY3)
Terminal #1: the Common (COM) position of Relay 3 (RY3)
Terminal #8: the Normally Open (N.O.) position of Relay 3 (RY3)
