Automatic Generator Start (AGS)
The RELAY AUX terminals can most easily perform “two-wire” generator start. A two-wire-start
generator is the simplest type, where the cranking and starting routine is automated.
It usually has a
single switch with two positions that is turned ON to start, OFF to stop.
Two-Wire-Start (RELAY AUX Terminals)
The RELAY AUX terminals can be wired in place of the generator’s start switch as shown below. This
method is only advised if the generator’s starting circuit is triggered by continuity. (This circuit must
use fewer than 10 amps.)
CAUTION: Equipment Damage
This circuit has no overcurrent protection. A fuse of no larger than 10 amps must
be installed to protect the circuit. Since the internal circuitry of the RELAY AUX
terminals do not incorporate overcurrent protection, it is the responsibility of the
installer to ensure the circuit is protected.
Internal failure that results from lack of
protection is not covered by the Radian warranty.
In other cases, or in the case of a three-wire-start generator, the AGS function should use the 12V AUX
terminals instead, in conjunction with a three-to-two wire converter. (See pages 32 and 33.)
Either the MATE3 or the FLEXnet DC battery monitor can be programmed to perform automatic
generator start using these terminals. See the MATE3 or FLEXnet manuals for programming
instructions.
