Chapter 2 Product Description

2.1 Product Features

1. Name: PSV-10 Cross-Contamination-Free Switching Valve is an electric injector valve independently developed by RUNZE Fluid Control Equipment Co., Ltd., also  known as electric rotary valve;
2. 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.
3. Corrosion Resistance: This type of switch valve adopts sapphire valve core, which can be applied to various corrosive liquids. The valve head are made of PCTFE  (polychlorotrifluoroethylene), 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 highly reliable.
6. Orientation: The valve hole is oriented by optical encoder, which can effectively solve the problem of inaccurate positioning after the gearbox is worn down.
7. 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;
8. Control Unit Interface: XH terminal with 2.54mm pitch
9. Usage: Widely used in the collection and distribution of fluid samples
10. 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 Cross-Contamination-Free Switching Valve 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 PSV-10 multicast channel 1 address marked as 00 to 81 by the command 0x50, set parameter 0x83 of multicast channel 3 address to 83  by command 0x52; Set parameter 0x81 of the multicast channel 1 address of PSV-10 marked as 01 to 81 by command 0x50, and the parameter 0x82 of multicast channel 2  address is set to 82 by command 0x51. Set parameter 0x82 of PSV-10 multicast channel 2 address marked as 02 to 82 by command 0x51, and the parameter 0x83 of multicast channel 3 address to 83 by command 0x52 (See the table below for details)

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 0x01，click to send and then the device 1 and device 2 will have port switching action; Set the address to 0x82 ,the command to 0x44 and the parameter to 0x03, click to send and then the device2 and device 3 will have port switching action; Set the address to 0x83, the command to 0x44, and the parameter to 0x05, click send and then the device 1 and device 3 will have port switching action; Set the address to 0xFF, the command to 0x44, and the parameter to 0x03 , click to send and then the device1.2 3 will all 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.

b: Valve parameter query command (common command) (B2~B4)

response parameter is the same as above parameter, it means the current version is V1.1, see the version number on the label for details
0x4A| Query motor status| B3=0x00| B4=0x00

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

such as a 10-ports switching valve, B3=0xXX B4=0x00,the value range of XX is 01～0A，
0x45| Reset| B3=0x00 B4=0x00 switching valve turns to optocoupler position and stop
0x4F| Reset on origin position| B3=0x00 B4=0x00
Switching valve runs to the encoder origin position, overlaps the position reset by the 0x45 command
0x49| Forced stop| B3=0x00 B4=0x00

Sum check (B6, B7)

package

Note: The sum check bit of the factory command is B12, B13 Response parameters are B2 B3 B4
Figure3-2-5 Response Parameters

Example: When using the query command “0x3E”, the response command Of B3 B4 =0x01 0x00 ~ 0x0a 0x00 Indicates multi-port 1-10
0x01| Frame error| B3=0x00| B4=0x00
0x02| Parameter error| B3=0x00| B4=0x00
0x03| Optocoupler error| B3=0x00| B4=0x00
0x04| Motor busy| B3=0x00| B4=0x00
0x05| Motor stalled| 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.

Chapter4 Common Problems & Solutions

is within the specified range
Not aspirating after switching| The channel is blocked by particles| Take out the pump tube and check for blocked particles
Liquid has bubbles| The connector interface is not tight| Replace suitable connector
No communication| The TX and RX lines of RS232 are connected reversely or RS485 phase A & phase B are connected reversely| Exchange the TX and RX line sequence of RS232, exchange the A B phase sequence of RS485
The communications sent and received are consistent in RS232| TX & RX are in short circuit| Check if there is a short circuit, if yes, replace the cable

Application Notice:

• Please ensure that the voltage matches the standard voltage of the instrument.
• Please use original serial port wires
• Communication RS232, RS485, CAN are under non-isolation mode, hot swapping unsupported.
• Please cover the unused ports with suitable coned plugs when laid aside to avoid impurity substance and air
•  Do not disassemble the product parts at will. The tamper-evident label is not guaranteed.
• Please read above operation instructions and communication protocols carefully, do not input data randomly.
• Discard the instrument should be in line with the regulations on the disposal. Dispose of the waste in accordance with national environmental protection requirements.  Users should not throw away at will.
• When using CAN bus protocols to connect multiple devices, please refer to the connection method shown in Figure 4-1 below.

• When using RS485 protocol to connect multiple devices, please refer to the connection method shown in Figure 4-2 below (CAN resistance is removed), However, the resistance value depends on the number of devices the user hangs.
