5-1 The introduction of the function
5.2.2 Function 1,2,9 and 11
Function 1 and 2 are the functions to calibrate the voltage and current value. Function 9 is to save the parameters, we have calibrated them before delivery, calibration is not needed under general condition, if necessary, please contact us. If mis-operation, you can use the function 11 to recover, press the OK key to restore factory Settings.
5.2.3 Function 4 and 5
Function 4 and 5 are the functions to set the maximum voltage and current value. The maximum voltage and current of this module are 60V, 20A. If you do not need to set such a big upper limit, for example, the upper limit of voltage and current you need are 30V, 5A, the output will not exceed the set values after the setting.
Function 4:press the “OK” key, then you can set the value of the over voltage protection. As shown below.
8
ZXY-6020S Programmable Power Supply
SET OVP VALUE
OVP= 0.00V
Users can move the position of cursor when pressing the “< >” key, rotate the adjust knob, regulate the voltage to 30.00V.
The setting of the current is similar to the voltage. After the setting, you should save the parameters in M0 according to function 13, then the parameters will be load automatically at boot time.
5.2.4 Function 3
The module has an intelligent temperature detection control function, the temperature detection value is a two digits which can reflect the radiator temperature, it is about 50 at normal temperature of 20°C, when the temperature increase 8 °C, the figures will reduce by 1. In the function 3, we can check the current radiator temperature detection value and the set value, the default set value is 0, indicating that the temperature control function is not started, when the power is in the output state, fan work, the power supply will not turn off automatically due to the high temperature.
If you want to turn off the output when the radiator temperature is about 100°C , you can set the OTP = 40 (specific machine may different), therefore, the fan start to work when the temperature is above 20°C, the module will control the speed automatically when the temperature between 20°C and 60°C, when the temperature is more than 60°C, it will run at full speed. The output will be cut off automatically when the temperature exceed 100°C, then it will send an alarm and the screen display error code E6.
After setting it, you need to use the function 13 to save the parameters in M0 .
5.2.5 Function 6,7 and 8
The three functions are over power protection, over AH protection and overtime protection. They have the similar setting method. Now with the OPP (overpower protection) as a case, we describe the setting method. Enter the
9
ZXY-6020S Programmable Power Supply
OPP, the screen will display:
SET OPP VALUE
OPP= 0.00W
The default setting is 0, indicating that the OPP function is off. You can set non-zero data to start it, for example, set the maximum power of 20W, you can press the“< >” key to select the cursor position, and adjust the knob or press “↑”, “↓” key to regulate the OPP value. After setting the output, when the actual output power exceeding 20W, the output will be cut off, then it will send an alarm and the screen will display error code E3.
OAH protection function is mainly used for setting upper limit when charging the battery, the machine will work continuously when it is 0, the OAH protection function will work when it is not 0, when the actual output AH is exceeding the setting value, the output will be cut off, then it will send an alarm and the screen display error code E4.
OFFTIME overtime protection feature allows the power off after a period of work. The machine will work continuously when the OFT=0. Setting a non-zero time, after exceeding the set time, it will cut the output automatically, then send an alarm and an error code E5.
The three functions also need to use function 13 to save parameters in the M0 in order to load at boot time.
5.2.6 Function 10
The module turn off by default, you should press the “OUT” key to output. If you want to output at boot time, you should set the function 10, switch to the “Start up: ON” state, then the module will output automatically at boot time. The functions also need to use function 13 to save parameters in the M0.
5.2.7 Function 12
The default setting of sound is open, if you do not need the voice prompts and alarm operation, you can set the function 12, making the “Sound Enable: OFF”.
10
ZXY-6020S Programmable Power Supply
The functions also need to use function 13 to save parameters in the M0.
5.2.8 Function 13
The parameters described above from 5.2.3 to 5.2.7 will be lost after the shutdown. If you need to save, you need to use the function 13, press “OK” key to save the setting parameters in M0, therefore every operation can automatically load at boot time. This machine has 10 storage positions from M0 to M9, if you need to save parameters in the M1 ~ M9, press the “< >” key to select the store location, then press “OK” key to save. If you need to load the parameters in M1 or others, you can repeatedly press the “< >” key when the machine is not output and the LCD has no cursor .
5.2.9 Function 14 and 15
Function 14 and 15 are the functions to set the address code and communication baud rate, this will be introduced in communication protocol of ZXY-6020S.
5.2.10 Function 16
Since the output of the charging mode is batteries, open the charging mode, power will be charged according to the general three-stage. When the battery is fully charged, it will enters the trickle charge mode automatically after the buzzer sounds, and the charging mode can simultaneously set OTP or OAH and other protect function at the same time .
Now we will use a 48V, 12AH lead-acid battery to explain the process of three-stage charging.
- Setting voltage of 58.5 V, current of 1.8 A, open the charging mode in the function 16 and save the settings in M0.
- Connect the battery, press “OUT” key, because the voltage of the battery is low, it can be seen that the battery is in constant current (CC) mode and the current is 1.8A, which is the first stage.
- When the voltage increase to 58.5 V, the current starts falling, the system is in constant voltage CV mode, which is the second stage.
11
ZXY-6020S Programmable Power Supply
4. With continuous charging, the current is gradually reducing, when the current is reduced to 1/10 of set value 1.8A, namely, 180mA, and now the buzzer rings out, the value of the voltage is reduced to 93.75% of original value, namely 54.8V. Under this voltage, the power supply charges the storage battery in trickle charge mode, which is the third stage.
5.2.11 Other important notices
- M0 is the default storage location, and the module can load the parameters in M0 automatically at boot time.
- The storage range of each position of this power supply is wide, including voltage and current values, various protection setting values, and whether automatically start on on boot time, sound options and others, which are stored in corresponding storage positions, and all storage positions are independent.
