CONSERV-R
®
IDLE CONTROL
The automatic Conserv-R® idle control is a gas saving, solid state
system, designed to reduce engine speed whenever the electrical load
is removed from the generator. Without a slow down control, the engine
would run at full speed at all times, regardless of the electrical load.
With the automatic Conserv-R® control switch in the “ON” position, the
throttle control lever is electrically released when the load is turned on
so it in no way interferes with the normal governor operation. When
the load is turned off, the idle magnet energizes and reduces the
engine speed. It does not cause incorrect operation of the carburetor or
governor.
The automatic Conserv-R® control consists of a solid state module
mounted in the generator receptacle box, a switch, resistor, and an
electromagnet mounted on the engine near the throttle lever. The
automatic Conserv-R® control is only offered asfactory installed
feature. It is not available for field installation.
With the automatic Conserv-R® switch in the “ON” position, the system
operates as follows:
1. After the engine has been started, and no electrical load is
applied, the solid state module senses this condition and turns on the
electronmagnet. This will pull and hold the throttle lever, closing the
throttle to the carburetor and reducing the engine speed.
2. When a load is applied to the generator, the current flow to the load
is sensed by the solid state control module and the electromagnet is
turned off. This releases the throttle arm, allowing the governor to take
over and open the throttle. The engine will respond and come up to the
governed speed (3600 RPM)
3. When the electrical load is turned off, the control module will sense
that there is no longer any current flow and the automatic idle control
will once again energize the electromagnet, pulling and holding the
throttle. When the automatic Conserv-R® switch is in the “OFF”
position, the engine will run at full governed speed, regardless of the
generator load.
CAUTION: EQUIPMENT DAMAGE
When using these generators to power a home or construction trailer,
the Conserv-R® switch must be left in the “OFF” position. Some
appliances in home and construction trailers have such a low current
draw (less than 5 to 10 Watts) they will not turn the Conserv-R® off,
resulting in low voltage being supplied to them. This low voltage can do
permanent damage to these appliances.
BATTERY INSTALLATION
This engine generator set is shipped with a battery tie down kit for
customer installation. This kit consists of a battery tie down and
hardware for installation of the customer supplied battery on the unit.
If you intend to use the power plant’s electric start system, you will
need to purchase and install a battery to operate it.
A 12 Volt battery, group U1 rated at 275 CCA or larger is recommended
for this electric start engine-generator set. Follow the battery
manufacturers recommendations for servicing and charging prior to
use. Connect the battery to the electric start system using the cables
provided.
CAUTION: EQUIPMENT DAMAGE
These electric start engines are NEGATIVE GROUND. Use extreme
caution when connecting the battery. Connect the NEGATIVE battery
terminal to GROUND.
For your safety, always connect the positive battery cable to the “bat+”
terminal first. Then connect the negative battery cable to the “bat-”
terminal. Make sure all connections are clean an tight. Reverse the
sequence when disconnecting, disconnect the negative cable first.
These engines produce enough direct current to keep the battery
charged under normal operating conditions, but were not intended to
be used as a battery charger.
WARNING: PERSONAL INJURY
Lead acid batteries produce explosive hydrogen gas when charging.
Keep sparks, flames, and burning cigarettes away from the battery.
Ventilate the area when charging or using the battery in an enclosed
space. Lead acid batteries contain sulfuric acid, which causes severe
burns. If acid contacts eyes, skin, or clothing, flush well with water.
For
contact with the eyes, get immediate medical attention.
BATTERY CHARGING
Units have a small flywheel charger built into the engine flywheel
assembly for recharging the starting battery. This flywheel charger
generates a small AC current that passes through a diode assembly
to produce DC charging current of about 1 to 3 Amps. This circuit is
not designed to be used as a battery charging circuit to recharge dead
batteries.
OPTIONAL DOLLY KIT
An optional 2-wheel dolly kit is available for this generator. The dolly kit
comes with instructions and parts list.
CAUTION: EQUIPMENT DAMAGE
Be sure to check the wheels properly before operating the generator.
Ensure the brake has been applied. Allowing the unit to move will
cause damage to the unit, drop cords or loads.
