2. When changes in voltage cannot be accepted.
3. When charging batteries.
Economy switch ON: 2800 rpm (with no load)
Economy switch OFF: 3550 rpm
The engine will run at 2800 rpm with economy
switch turned on, if the electrical consumption is
below 1/4 of its rated output.
When a light and electric motor are connected to the
generator at the same time, turning one of the
devices on and off causes a change in voltage and
could have an adverse effect on the other device.
In these kinds of cases, first turn the economy
switch off before use.
Throttle valve operation:
■
The throttle valve is fully opened when the
engine is not running.
■
When the engine is started with no load, the
throttle valve will be set in an almost completely
closed position as soon as the engine is started.
(When the economy switch is “ON,” it will be in
a position to maintain 2800 rpm.)
■
The engine speed will be adjusted according to
the requirements of the load on the system.
■
The throttle stops at the fully opened position
when the engine is turned off in order to prepare
for the next attempt to start the engine.
In temperatures of 0° or below, the engine will auto-
matically run at 3550 rpm for three minutes for
warming up purposes, even when the economy
control switch is turned ON.
Throttle Motor
Caution during resistance measurement:
Do not allow the lead wire of the tester to touch the
next terminal when measuring the resistance
between terminals.
Caution during assembly:
To prevent damage to the throttle valve when reas-
sembling the carburetor,
re-install the carburetor
with the throttle valve fully opened .
If the engine is difficult to start after the carbure-
tor is installed, fully open the throttle valve by
hand and then start the engine .
Economy Control Operation and Features
Because output frequency of an inverter generator
is unrelated to the engine speed, it is possible to use
a wide range of engine speed.
It also becomes possible to use low engine speed to
meet a low electrical consumption.
The control unit commands the throttle motor built
into the carburetor to control the throttle valve, which
gives it the ability to continuously control the engine
speed, which in turn makes the economy control
system possible.
However, the economy control switch
should be
turned off
in case of the following occasions:
1. When operating an electric motor, such as
water pump, which requires a large starting cur-
rent.
