2.5.3 Generator Start/Stop Connections (Terminals 1, 5, 6, 7, and 8)
This section details the control relays inside the AGS controller and 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 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 auto-start/stop function 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 genera-
tor 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 the 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 ‘Gen-
erator 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).
