Chapter2 Product Introduction

Product Features

Name: The injector valve is an electric injector valve independently developed by RUNZE Fluid Control Equipment Co., Ltd., also known as electric rotary valve;
Control: By receiving instructions from the host computer to control the operation of the stepper motor to make the rotor turn to the specified port position to achieve the switching of the flow path. Serial communication protocol supports RS232/RS485/CAN bus.
Corrosion Resistance: This type of injector valve adopts sapphire valve core, which can be applied to various corrosive liquids. The valve head are made of PCTFE (polychlorotrifluoroethylene) and PPS, maintenance-free;
Valve Core Structure: The valve core adopts a multi-directional self-adaptive plane fitting method, which can extend the service life of the product effectively. (This structure has been applied for utility patent, patent number: CN204852471U)
Motive power: The rotation of the valve body adopts the imported NMB planetary gearbox motor as the power plant, which is extremely reliable.
Orientation: The valve hole is oriented by optical encoder, which can effectively solve the problem of inaccurate positioning after the gearbox is worn down.
Driver: The two-phase bipolar stepper drive module is a constant current drive chip, which can control the motor current with high efficiency. It has a built-in error detection circuit and error detection (TSD/ISD) signal output function;
Control Unit Interface: XH terminal with 2.54mm pitch
Mechanical Interface: 1/4-28UNF internal thread
Usage: Widely used in the collection and distribution of fluid samples
Application: Environmental testing devices, experimental analysis instruments, medical analyzers, chromatographic instruments, etc. Before using the injector valve, please read the “Instruction Manual” carefully and follow the provisions in it.

Example: Use the 0x50/51/52/53 command to set the multicast address (only uses 0x50/51/52 three commands in this example)
Use three sets of SV04B injector valves with the same software version. In the RS485 communication mode, set their addresses to 00, 01, 02 and make a mark. Firstly, Set parameter 0x81 of SV04B multicast channel 1 address marked as 00 to 81 by the command 0x50, set parameter 0x81 of multicast channel 2 address to 81 by command 0x51; Set parameter 0x82 of the multicast channel 1 address of SV04B marked as 01 to 82 by command 0x51, and the parameter 0x82 of multicast channel 2 address is set to 82 by command 0x52. Set parameter 0x83 of the multicast channel 1 address of SV04B marked as 00 to 83 by command 0x50, and the parameter 0x83 of multicast channel 3 address to 83 by command 0x52 (See the table below for details)

Device Item| Devicel (address 0)| Device2 (address 1)| Device3 (address 2)
---|---|---|---
Multicast address| 81(2)| 81(2)|
Broadcast address| FF(1)| FF(1)| FF(1)
Multicast address| | 82(2)| 82(2)
Broadcast address| FF(1)| FF(1)| FF(1)
Multicast address| 83(2)| | 83(2)

After the setting is completed, connect the three devices in parallel to the serial debugging tool, and use our debugging tool MotorTest V0.8 for debugging. In MotorTest V0.8, set the address to 0x81, the command to 0x44 and the parameter to 0x02, click to send and then the device 1 and device 2 will have port switching action; Set the address to 0xFF ,the command to 0x44 and the parameter to 0x01, click to send and then the device1.2 3 will all have port switching action; Set the address to 0x82, the command to 0x44, and the parameter to 0x02, click send and then the device 2 and device 3 will have port switching action; Set the address to 0xFF, the command to 0x44, and the parameter to 0x01 , click to send and then the device1.2 3 will all have port switching action; Set the address to 0x83, the command to 0x44, and the parameter to 0x02 , click to send and then the device1 and device 3 will have port switching action;
The newly added command to set the multicast address greatly meets the needs of customer groups, making it easier and more convenient for customers. You can choose the device you want to control so that you can complete your work more efficiently and quickly during usage.

Note: After version V1.8, the software sub-version and the main version are merged into one

c: Valve action command (common command) (B2~B4)

Command Code B2| Command Instruction| Parameter Instructions (B3, B4)
---|---|---
0x44| The motor rotates through the code disc, and select the best path automatically| According to the actual number of ports of the injector
valve, such as a 10-port injector valve, B3=0xXX
B4=0x00,the value range of XX is 01～0A，
Note: 6-port State1 1-6 connected
8-port State1 1-2 connected

0x00| Normal state| B3=0x00 B4=0x00
Example: When using the query command
“0x3e”, the response command
Of B3 B4 =0x01 0x00 ~ 0x0a 0x00
0x01| Frame error| B3=0x00 B4=0x00
0x02| Parameter error| B3=0x00 B4=0x00

0x06| Unknown position| B3=0x00 B4=0x00
0xFE| Task is being executed| B3=0x00 B4=0x00
0xFF| unknown error| B3=0x00 B4=0x00

Note: In RS485 communication, when sending an action command, when code B2 received FE byte means the command is received and is being executed
Note: ⑴ The code B2 in the response command indicates the current running state of the motor. Only when B2=0x00, the motor is in normal operation, other parameters are as shown in the above table, corresponding to different abnormal states respectively. In principle, the motor should be sent the 0X4A command to query the motor status at the end of the motor operation. Only when the B2 parameter in the response command is 00, other commands can be executed correctly.

Note: The code parameters of all the above commands are set in little- endian mode. low data stored in the low bit of the address, high data is stored in the high bit of the address.

SV04B CE Certification Recommended Circuit Diagram in Application

Since the SV04B injector valve can only exceed 500V in the surge test, if it is used in a harsh environment (such as high-voltage power, lightning strikes), then it is recommended that the user should add a surge protector to the power supply end of the SV04B to pass the 4th level (4KV).
