Appendix A: Generator Auto Start Requirements and Types
Three-Wire Automotive
The third generator starting type that is supported by the AGS is similar to
an automotive-style ignition. In this style, the generator uses a run circuit
that is normally closed, which then receives a momentary start signal. The
run circuit remains active throughout the run and then is opened in order for
the generator to stop.
Identification
Generators of this type are controlled by a key or rotary switch that acts
exactly as an automotive ignition. The switch is first turned to an “on” (or
run) position, then further to a start position. After starting, the switch
returns to the “on” (or run) position. Other variations are a toggle switch
that gets turned on with a separate switch or push button for start. If glow
plugs are used, you would turn the key or rotary switch to the left prior to
starting. A separate momentary switch or button may be used for this
purpose.
Connection
This generator starting type uses the most wires. The common wire from
the generator should connect to the common connections of both Relay 1
and Relay 2 (wires 16 and 18 respectively). You may need an additional two
wires if glow plugs are used. The start wire from the generator connects to
the normally open contact of Relay 2 and the generator stop wire connects
to the normally open contact of Relay 1.
