Function mode and display code instruction

Note 1: Under voltage protection value must be smaller than Overvoltage recovery value , or it will restore factory setting 

Note 2: Under the setting mode , mode 1 to 7  all can display the function mode , backlight mode ,  Delay time in load switch on after input power on , but the following display will difference according to the function mode. 

Key operation instruction

• Press and hold on the set key for 3s, entering into setting status and if go on hold the set key , it can select  different function mode . then you can set different value by pressing the up key or down key to increase or decrease the detailed value. if you hold  up key or down key at all , the value will increase or decrease at all .
• Under the function mode , hold on the set key for 3s , it will save and exit to normal display status . if you have no any operation more than 30s  , it will also exit to normal display status . if you press the he up key or down in the meantime ,all data will restore factory setting
• Under the normal display status , you can display voltage/current/active energy/active power step by step by  pressing the up key or down . the LCD will display step by step automatically
• Under the function mode 2 , you can press the he up key or down in the meantime to make the output load switch on after happen protection /switch off
• Under the function mode 1 and 2 , it the press the  down key to check the last five records of protection reason(Er1  Er5 ) .under the display firstly layer is  Er1 , the second layer number : 1 means the  overvoltage protection, 2 means under voltage protection , 3 means over-current protection , 4 means
• Under the function mode 3 and 4 , all protection function will be closed . the product is only as normal switch for keep the output load is switch on/off
• Under the function mode 5/6/7 , all protection function will be closed . the product is only as normal switch for keep the output load is switch on/off  in cycle .

LCD display instruction

• normal working status LCD display

• Under function mode setting and value setting LCD display

• Under function mode s5/6/7  LCD display

Usage

• The product can be installed on  35 mm din rail ,it should be install in the water proof box indoor or outdoor . The product should be install fully in accordance with connection diagram on the terminal cover, it is better to use copper as the leading wire for connection. All screws should be tightened. 
• installation dimension

• Connection diagram

Wire connection must connect as sequence of the above 2 type diagram

Note

• The input and output shall be corrected connected on the basis of the product marking. (Where in, the load current shall be less thanprotective current of the product. )
• Neutral line N cannot be improperly connected and shall be reliably wired; otherwise, the protector may not work normally.
• Before powering on, please carefully check whether the wiring is correct, whether the load matches with protective current of the product and whether the binding screw is tightened; otherwise, the product may be damaged.
• After powering on the product, don't touch any live part to avoid electric shock.
• This product shall be combined with micro circuit breaker to play a role of short-circuit protection; otherwise, the product may not be able to realize load limit protection in case that input or load end of the product appears short circuit.
• As the product has automatic reset function, after the product plays the role of protection and acts, it is necessary to remove the load (electric appliance) and check the circuit; otherwise the product will be frequently connected and disconnected to the load. Finally, the product or its circuit may be burnt due to frequent overload connection and disconnection for long time.
