Serial communication protocol supports RS232/RS485/CAN bus. (3) 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; (4) 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) (5) Motive power: The rotation of the valve body adopts the imported NMB planetary gearbox motor as the power plant, which is extremely reliable. (6) Orientation: The valve port is oriented by optical encoder, which can effectively solve the problem of inaccurate positioning after the gearbox is worn down. (7) Drive: 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; (8) Control Unit Interface: XH terminal with 2.54mm pitch (9) Mechanical Interface: 1/4-28UNF female thread (10)Usage: Widely used in the collection and distribution of fluid samples (11)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. http://www.runzeliuti.com 4 2.2 Naming Rules Figure 2-2 Example: Slope type 10-port sapphire injector valve, naming: QHF-SV07B-X-T10-K1.2-S 2.3 Product Specification SV-07B injector valves can be divided into 6 ports, 8 ports, and 10 ports according to the number of channels, as shown in the figure below: 6 ports 8 ports 10 ports Figure 2-3-1 The 6/8/10 ports can be installed in place of other injector valves of our company.

In the RS485 communication mode, set their addresses to 00, 01, 02 and make a mark. Firstly, Set parameter 0x81 of SV07B 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 SV07B 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 SV07B 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) Item Device Multicast address Device1 (address 0) 81(2) Device2 (address 1) 81(2) Broadcast address FF(1) FF(1) Multicast address 82(2) Broadcast address FF(1) FF(1) Multicast address 83(2) Device3 (address 2) FF(1) 82(2) FF(1) 83(2) http://www.runzeliuti.com 12 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.

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 is stored in the low bit of the address and high data is stored in the high bit of the address. http://www.runzeliuti.com 15 Chapter 4 Common Problems & Solutions Phenomenon Not working when powered on Not aspirating after switching Liquid has bubbles No communication The communications sent and received are consistent in RS232 Application Notice: Possible problem Working voltage is not within the specified range The power connection is loose or disconnected Working current is not within the specified range The channel is blocked by particles The connector interface is not tight The TX and RX lines of RS232 are connected reversely or RS485 phase A & phase B are connected reversely TX & RX are in short circuit Solution Check whether the voltage is within the specified range Check the power connection Check whether the current is within the specified range Take out the pump tube and check for blocked particles Replace suitable connector Exchange the TX and RX line sequence of RS232, exchange the A, B phase sequence of RS485 Check if there is a short circuit, if yes, replace the cable Please ensure that the voltage matches the standard voltage of the instrument.
