Section6-The controller box failure.
1.The engine can not change speed. The step motor no control.
Method:
IIf adjust have no effect Please change a new one.
Adjust controller (120V / 60Hz)

Why need adjust the controller box?
The machine can normally for running, but the noise is not smooth or output voltage is not steady,
under this circumstance, the machine need to adjust the control box.
A
B
is ECON=OFF adjust knob, when ECON=OFF,
the three -phase voltage reading is AC 210V± 5V,
in clockwise to increase the voltage, in
counter-clockwise to reduce the voltage.
is ECON=ON adjust knob, when engine at low
speed idle the three-phase voltage reading
AC 170V±5V, in clockwise to increase the voltage, in
counter-clockwise to reduce the voltage.
1. When need to adjust knob?
When the machine is with 100% load, and then shift the ECON switch from ECON=ON to ECON=OFF,
if you feel that the engine speed and the three -phase voltage reading figure have big difference ,
need to adjust the knob.
Adjusting method:
When the generator is with 100% load, please take the ECON=ON as the base normal three -phase
voltage 150V-155V, and then swift to ECON=OFF, if the three-phase voltage is not in the range of
150V-155V, please turn the knob in clockwise to increase the voltage, or turn the A knob in
counter-clockwise to reduce the voltage.
In one word, in the normal condition do not need adjust the knob.

2. How to adjust knob? (Mainly for adjust B knob)
1)Runing the machine.
2)Measure blue wire connector:
The three -phase voltage reading need 170V(0% load ECON=ON). When ECON=OFF The the
three -phase voltage reading will about 200V.
The three -phase voltage reading need 150~155V (100% load ECON=ON, ECON=OFF are
the same reading) .
B
1-2, 1-3, 2-3 the voltage reading about 5V error.
The three -phase voltage so low or error large can cause the output voltage low.
3) Adjust method:
In the Step motor control module have knob, That can change the three -phase voltage.
Clockwise is to low & counter-clockwise is to high.
Three -phase voltage, please according as follow:
1) When on: 0% load the voltage about 170V. (ECON=ON)
2) When on: 100% load the voltage about 150~155 V. (ECON=ON, ECON=OFF)
