Wiring Diagram

Note:

1. Commonly used active modes such as PLC inverter servo valves, passive mode is used for special controllers, and 24V is required for output.
2.  It is the internal resistance of the device, we don’t need to connect it again.

How to judge whether it is the active or passive connection? Common methods are

1. See the internal schematic document of the device, I+ is 24V+, it is the passive connection: I- is 24VG, it is the active connection:
2. Use a multimeter to measure the voltage between I+ and I-, =0V is the active connection, =24V is the active connection:

Voltage/Current switching

Press the MODE button, one key switch to adjust the voltage and current mode； The indicator shows what state it is in， System operation corresponds to which mode to  operate The original mode after switching, Will continue to output It’s just not in a state of adjustment ；

System Operation ( Where “OK ” is：Push the knob down Turn clockwise to ”+< ADD >”，
Anticlockwise rotation ” – < reduce> ”) ：

6.1 In the normal operation screen, short press the Confirm key to save the output value，After letting go， the Screen display”…”, Successfully saved, After the next boot, The  output value is this saved value ； When debugging equipment ， We need to randomly adjust the output value Just don’t press the encoder knob， After restarting, the  original value will be saved；
6.2 Parameter settings：
6.2.1 In the normal operation screen, Press and hold the confirm button for 2 seconds, Enter setting state， and Display” F001”(Parameter number 001);
6.2.2 Turn the knob to change the parameter number (First entry F002 Need to enter the password first“+ – – + （Rotate the knob）”)；
6.2.3 Parameter number interface， Press the Confirm key to enter the corresponding parameter value setting， Rotate the knob to modify the parameters；
6.2.4 Press the Confirm key to save the parameters， Exit the parameter setting，
Display the next parameter number（No password is entered, after setting the F001 value, it will enter the normal operation screen）；
6.2.5 Rotate the knob directly to the last parameter number, press the OK key, the setting is completed, and enter the normal operation screen;
6.2.6 If there is no operation on the parameter setting screen for more than
10s, it will exit the setting state and enter the normal operation screen;
6.3 For example:
6.3.1 Modify “F001” coarse and fine adjustment mode

Figure 1 →2: Press and hold the knob for 2 seconds， Enter a setting state Display
“F001”;
Figure 2 →3: Press “OK”，Set the value of “F001” 设，Turn the knob to modify it ；
Figure 3 →4: Press “OK”，Exit the setting state after saving，Enter the normal adjustment state；6.3.2 Modify “F006” calibration value （It ’s best to adjust the output to 10V or 20mA first, and Recalibrate ）

Figure 1→2: Press and hold the knob for 2 seconds，Enter setting state，
Display“F001”;
Figure 2→3: “+”1 Pulse，Display“- – – -”；
Figure 3→4: Enter password“+ – – +”，Display“= = = =”；
Figure 4→5: Press “OK”, if the password is entered correctly, it will display
“F002”, otherwise it will display “Err” to exit, there may be an error, please enter it again;
Figure 5→6: Rotate the knob “+” to display “F006” ；
Figure 6→7: Press “OK”, Enter to set the parameter value of “F006”, Then modify
this value, Make the actual output equal to the display value before entering the
setting state;
Figure 7→: Press “OK” to save, or automatically exit the setting state after 10s of inactivity, and the parameters will not be saved;
6.4 In the voltage regulation mode, enter the voltage setting, parameter description table：
6.5 Enter F002, you need to enter the password first“+ – – +(Turn the knob to display—-)”

6.6 In the regulation current mode, Enter the current setting,
6.7Parameter description table:you need to enter the password first“+ – – +(Turn the knob to display—-)”

 Current output test method: AIo GND

We often encounter people who say that there is no current when measuring current. In fact, the ammeter is broken, the gear is wrong or the wrong hole is inserted. There is a  fuse inside the multimeter to measure the current. This is easy to blow, so we use the method of voltage measurement. Verify the transition of the signal generator as follows:  7.1 The simplest method: power on, directly measure the voltage between AIO and GND when there is no load, =0V is defective, otherwise 99% may be no problem because  when there is voltage to measure current, it is equivalent  to short circuit and there will definitely be current ；

7.2 Connect an LED indicator, if the brightness changes with the adjustment, then the signal generator current output is no problem;
7.3 Connect a 50-300 ohm resistor to AIo GND. If there is voltage and it meets
“Voltage = Current X Resistance”, the voltage will change with the adjustment, then the signal generator current output is no problem;
7.4 If there is a PLC/inverter, measure the resistance between I+ and I-. If it is between 50-300 ohms, you can use it as a test resistance. Connect AIO to I+,
GND to I-, and measure the voltage. If there is voltage, and Satisfy “Voltage

Current X Resistance”, the voltage will change with the adjustment, then the signal generator current output is no problem;

NOTE：
8.1 Please read this manual carefully before use ；
8.2 Turn off the power before wiring
8.3 Exceeding the range shown in the technical indicators may cause the instrument to work abnormally or even be damaged；
