Connecting Electrical Loads; Stopping The Engine - Craftsman 580.327060 Owner's Manual

OPERATION
CONNECTING ELECTRICAL LOADS
• Use this generator to operate 120_240 volts, single
phase, 60 Hz, a-c lighting, appliance, tool and motor
loads.
DO NOT connect 240 volts to the 120 volts duplex
receptacles.
DO NOT connect any 3-phase loads to panel recep-
tacles.
DO NOT connect any 50 Hz loads to the generator.
Add up the rated watts of all lights, tool, appliance and
motor loads you are powering at one time. This total
should NOT be greater than (a) the generator's rated
wattage capacity, or (b) the circuit breaker rating of the
receptacle supplying power. See "Don't Ovedoad the
Generator" on Page 7.
STOPPING THE ENGINE
ZDLE
CONTROL
SYSTEM
HG. 8
Unplug all electrical loads from the generator panel
receptacles. Never start or stop the engine with electri-
cal devices plugged in and turned on.
Let the engine run at no-load for several minutes to
stabilize the internal temperatures of engine and gen-
erator.
Push Stop Switch (Fig. 7) against spark plug and hold
until engine has come to complete stop.
AUTOMATIC IDLE CONTROL
An Automatic Idle Control system provides greatly im-
proved luel economy by operating the unit at its normal high
governed speed only when electrical loads are plugged in
and turned on. The system consists of (a) an Idle Control
Circuit Board, (b) a Sensing Transformer, (c) an
Electromagnet, and (d) an Idle Control Switch (Fig. 8).
Idle Control Switch ON: Engine-generator runs at high
governed speed only when an electrical toad is connected
to the generator and turned on. When the electrical load is
disconnected, an Electromagnet is energized to pull the
engine throttle control against its idle stop. Engine then
runs at reduced (idle) speed.
Idle Control Switch OFF: The Electromagnet cannot be
energized, since its power circuit is open. Engine runs at
high governed speed (about 3600 rpm) whether load (s) are
connected or not.
The Idle Control System may be briefly described as fol-
tows:
Power voltage for Electromagnet operation is available
to the Idle Control Circuit Board, via Wires 11D and 22.
When an electrical load is not plugged in to panel
receptacles, no current flows through the Sensing
Transformer primary winding and no current flow is
present in the Transformer secondary winding. The
Idle Control Circuit Board then completes the circuitto
the Electromagnet, which energizes to pull the engine
throttle back against its idle stop. The .engine-gener-
ator runs at idle speed.
When an electrical load is plugged in, current flows
through the primary windings of the Sensing Trans-
former, to induce a current flow into the Transformer's
secondary windings..This current flow to the load is
"sensed" by the Idle Control Circuit Board, via Wires
155 and 156. Circuit board action then opens the
power circuit to the Electromagnet, which de-ener-
gizes. The engine governor then maintains engine
speed at about 3600 rpm.
