ME-AGS-N Manual

Installation

Two-wire control generator types: These generator types

integrate the control circuits for start-up, running, and stopping

(Figure 2-13). The generator starts and runs when two control wires

are connected, and then stops when they are disconnected.

Three-wire momentary control generator types: These

generator types use a 3-position momentary type switch that

controls their operation (Figures 2-14 & 2-16). To start the generator,

the switch is momentarily held in the START position. This energizes

the ignition system and cranks the starter motor. Once the engine

has started, the switch is released and returns to a center position

(i.e., “momentary” run control). To shut down the generator, hold

the switch in the STOP position until the engine dies. Once released,

it returns to the center position (i.e., “momentary” stop control).

Three-wire maintain control generator types: These generator

types use an automotive type starting circuit (Figure 2-15). To start

the generator, turn the operating switch to a RUN position and then

momentarily hold it in the START position. Once the engine starts,

release the switch and it returns to the RUN position (i.e., “maintain”

run control). To shut down the generator, move the switch to the

OFF position (i.e., “maintain” stop control).

2.7 Warning Label

It is unsafe to perform maintenance on the generator/electrical panel

if just the generator is turned off. The AGS system can automatically

turn on the generator and power the panel. See Figure 2-12.

The supplied warning label informs all that an automatic generator

starting device is installed in your electrical system. Place the label

in a clearly visible location at the generator (ensure it is visible

at the generator cabinet or at the enclosure that guards against

electrical shock or moving parts hazards).

WARNING: To protect servicing personnel, ensure the

generator and AGS are properly disabled (i.e., remove starting

battery from generator and remove all power to the AGS by

unplugging the AGS’s terminal block) prior to performing

maintenance on the generator or electrical panel.

WARNING

ELECTRICAL SHOCK HAZARD

PN: 62-0002 Rev B

This electrical system is equipped with an Automatic Generator

Starting (AGS) device and/or an inverter. Disconnect all AC and

DC power to the AGS and/or inverter before performing any

service to the electrical system. Failure to do so can result in

shock causing serious injury or death.
