Standard-Mode:
  
After connecting the battery, enter the Standard Mode (default), and display the current battery voltage(Current Voltage) 
   
-Saving mode:
In standard mode, press and hold the ''SET'' button to enter the -Saving Mode. After power on again, it will still enter the -Saving Mode. In the -Saving Mode, the digital tube is not displayed, and other functions work normally. In the -Saving mode, press and hold the ''SET'' button, exit the -Saving Mode, and enter the Standard Mode.
 
Setup-Mode (see Operation Steps for details):
  
Set the Start-Discharge-Voltage (High voltage):
In the Standard-Mode, press and hold the ''INC'' button (or trigger the ''SET'' button after triggering the ''INC'' button) to enter the Start-Discharge-Voltage Setup-Mode.
 
Set the Cutoff-Discharge-Voltage (Low voltage):
In the Standard-Mode, press and hold the ''DEC'' button (or trigger the ''SET'' button after triggering the ''DEC'' button) to enter the Cutoff-Discharge-Voltage Setup-Mode.
 
In the Setup-Mode ,triggering the ''INC'' button increases the voltage and triggers the ''DEC'' button to decrease the voltage. Long press ''INC'' or ''DEC'' button to quickly set the voltage.
 
Voltage-Calibration:
Press and hold the ''SET'' button first, and then power on again to enter the Voltage-Calibration mode(Note: press the button ->power on).
  
For example, the power supply voltage is 12.00V and the module display voltage is 12.34V. At this time, calibration is required.
  
1.Press and hold the ''SET'' button first, and then power on (be sure to press the button first, and then power on), then the digital tube displays 12.34V;
 
2.Trigger ''DEC'' or ''INC'' button, let the  digital tube display 12.00V  
  
3.Trigger the ''SET'' button again to save the parameters. (If you do not want to save the parameters, please power off)
  
Factory-Settings:
In the Standard-Mode, press and hold  the ''SET'' and ''INC'' buttons at the same time, until the digital display shows''8888'', at this time, restore the factory settings, Cutoff-Discharge-Voltage  is 11.8V, Start-Discharge-Voltage is 12.8V. (Note: voltage calibration parameters cannot be reset to factory settings)
 
Operation Steps (must follow the steps):
  
Example 1: We want to set 12V lead-acid battery discharge protection function, Cutoff-Discharge-Voltage is 11.7V and Start-Discharge-Voltage is 12.9V.
   
Step 1: Connect the battery's positive and negative ports to the module's BAT+/BAT- ports (to ensure that the battery has more than 20% of the capacity); the digital tube will display the battery voltage (such as the battery voltage is 12.1V, the digital display will show ''C12 .1'')
   
Step 2: Trigger the ''INC'' button, the digital display will show ''H12.8'', then trigger the ''SET'' button, ''H'' will flash, this is the Start-Discharge-Voltage setting mode.
    
Step 3: In the Start-Discharge-Voltage setting mode, trigger the ''INC'' button to increase the voltage and the ''DEC'' button to decrease the voltage. Long press ''INC'' or ''DEC'' button to quickly set the voltage.
   
Step 4: Set the voltage to ''H12.9'' and trigger the ''SET'' button to save the settings.
   
Step 5: Trigger the ''DEC'' button, the digital display will show ''L11.8'', then trigger the ''SET'' button, ''L'' will flash, this is the Cutoff-Discharge-Voltage setting mode.
   
Step 6: In the Cutoff-Discharge-Voltage setting mode, trigger the ''INC'' button to increase the voltage and the ''DEC'' button to decrease the voltage. Long press ''INC'' or ''DEC'' button to quickly set the voltage.
   
Step 7: Set the voltage to ''L11.7'' and trigger the ''SET'' button to save the settings.
   
Step 8: Disconnect the port BAT +/BAT- and connect the port OUT+/OUT- to the load.
   
Step 9: Connect the port BAT +/BAT- again and re-power it. After 3 seconds delay, the load will be .
 
 
Example 2: Start-Discharge-Voltage(H) and Cutoff-Discharge-Voltage(L) has been set, Direct wiring.
Step 1: Connect port OUT+/OUT- to the load
 
Step 2: Connect the battery's positive and negative ports to the module's BAT+/BAT- ports (to ensure that the battery has more than 20% of the capacity); the digital tube will display the battery voltage (such as the battery voltage is 12.1V, the digital display will show ''C12 .1'')
 
Step 3: Power is supplied to the load after a delay of 3 seconds
 
   
   
 
Q&A:
 
Q1: The suitable battery voltage? Types of Batteries?
A1: This module is suitable for all batteries in the range of 6-30V, lead-acid batteries, lithium batteries and even dry batteries.
    Battery type : Lead-acid  /Ni-Cd / Ni-MH / Li-ION /Li-PO / LiFe /Polymer Lithium battery.
   
Q2: Can parameters be saved after power off?
A2: Yes, the parameters can be saved when off.
   
Q3: Why does the digital tube not display after the battery is connected?
A3:  1. It may be that the battery capacity is too low. Please charge the battery with the charger first.
     2. Poor connection or reverse polarity
     3. It is possible that the module has entered the -Saving Mode,press and hold the ''SET'' button until the digital display.
   
Q4: Why can't I increase the '' Cutoff-Discharge-Voltage(L)''?
A4: Please increase the Start-Discharge-Voltage(H) first.
   
Q5: Why can't I discrease the '' Start-Discharge-Voltage(H) ''?
A5: Please discrease the Cutoff-Discharge-Voltage(L) first.
    
Q6: Why relay turn on and off frequently?
A6: 1 It may be too much load current, or the battery capacity is too small.
   2 It may be Cutoff-Discharge-Voltage(L)  and Start-Discharge-Voltage(H)            too close.
   
Q7: What is the control method?  Can it be used as a charge protection?  Can it limit the current?
A7:  1 This is a voltage control method
      2 NO! This can only be used for discharge protection. It cannot be used for charging protection. For charging protection, please use the PS46A01 module.
    4 No! This module can only control the voltage and cannot control the current. Can not limit current, the current size depends on your load current and battery maximum current
    
Q8: Does this protection board have voltage regulation function?
A8: No! This module is just a voltage controller and can only function as a switch without boost or buck function..
