2.3 Corner position sensor
The angular position sensor is mounted coaxially with the
rotor of the angular motor. The sensor is a linear, non-contact
angular position sensor. Its power supply voltage is 5VDC. The
feedback voltage is approximately: 1.6VDC at 0 ° corner,
3.3VDC at 75 ° corner (refer to 0V voltage measurement).
三 installation
Use caution when unpacking the position control valve. If
you find that the casing is deformed, scratched, or damaged,
please contact the supplier immediately.
3.1 power supply
The power output should be low-resistance (for example,
directly from the battery). The power connection wire uses
two-core insulated sheathed wires, and the ground wire uses a
single-core insulated sheathed wire. Neither the power or
ground wires need to be shielded.
If the power source is a battery, make sure the system has
an alternator or other battery charging device.
When the engine is stopped, the ESC will control the
corner motor to maintain the minimum position. At this time, if
the battery charging system is turned off, it may cause the
battery to run out of energy. To prevent this, the control system
should be closed with a switch or relay. The switch or relay
should be interlocked with the engine start switch to prevent
the engine from starting when the power to the ESC system is
cut off.
3.2 Warning-speeding
Do not use the power off method to stop the engine. Do
not turn off the power on the controller during shutdown
operation. Because closing the control valve plate will be in a
free state, all control valve position commands come from the
controller, through the drive circuit, and finally to the corner
motor. Turning off the power to the controller while the engine
is running may cause the engine to overspeed.
3.3 Position speed control valve installation
The KZ55 position speed regulating valve is suitable for
installation on the gas line of an engine or the intake pipe of an
engine below 150KW for gas or mixer air intake control. When
the position regulating valve is working normally, the current is
≤
0.5A, and the heat generation is very small. Only under the
conditions of blocked rotor or other conditions that require the
maximum torque output, large heat will be generated. The main
heat of the speed control valve comes from the heat transferred
by the engine.
The installer should consider the thermal conductivity of
the mounting bracket and the engine body temperature at the
installation location. If the engine body temperature at the
installation location is too high, appropriate insulation
measures should be taken. Under normal circumstances,
aluminum and low carbon steel materials with higher thermal
conductivity should be selected as the mounting bracket, and
the installation location should be selected in a place with good
air circulation.
If there is a problem with the operating temperature,
please contact the manufacturer's engineer.
The installation method is shown in Figure 3-1. The
connection flanges are installed on both sides of the valve body,
and the contact surfaces are sealed with rubber rings. The
connection pipe can be connected to the flange.
Manual detection: The scale corresponding to the pointer
of the position control valve is the opening angle of the valve
disc. Before starting, pull the handle to confirm that the valve
disc rotates without jamming.

skills requirement
：
1. The position control valve harness motor wire uses
more than 1.5 strands of plastic copper wire, and the sensor
wire uses 0.5 shielded wire. The length of the used wire is
≤
20m.
2. To connect the position control valve, just connect the
aviation plug of the corresponding wiring harness with the
aviation socket on the position control valve, and connect the
other end of the wiring harness to the corresponding terminal of
3120A as shown in Figure 3-4.
