Quick Details
Specifications
1. Using MCU and special software, based on the special software of the expert control system, realizes the intelligent optimization SOC control.
2. The temperature compensation adopt external temperature sensor, the control accuracy is higher than the internal temperature sensor.
3. Have the overcharge, discharge, electronic short-circuit, overload protection, unique counter-attack joint protection automatic control; Above the protection are not causing damage to any component, and don't burn the fuse.
4. Adopt the tandem PWM for charging main circuit,make the charging loop voltage is reduce nearly half than use the diode charging circuit.The charging efficiency is higher 3%~6% than the non-PWM, increased the power of time. Enhance the charge of over-discharge recovery, normal direct charge, the float-charge automatically controlled way can make the system has a longer use life.
5. The intuitive LED iuminotron indicates the current battery status, allow users to understand the situation of use.
6. The all control adopt the technical grade chip,can run freely in cold,high temperature,damp environment. At the same time use the crystal oscillator timing control, precise timing control.
7. Using the digital LED display and Settings, a key type operation can complete all Settings, use is very convenient for intuitive.

Instructions:
1.Battery status indicator:
Battery voltage in the normal range, state lamp (2) is green normally on; When in the full state the indicator is green and slow flash; When the battery voltage reduced to undervoltage,state light turn into orange ; When the battery voltage continue to reduce to the over discharge voltage, state lamp (2) turn into red, the controller will automatically shut down output, warn the user to supply electric power in time. When the battery voltage returned to normal working scope, will be automatically enabled output open, state lamp (2)turn into green.
2.Load instructions:
When the load is opening, the load lamp (3) is on normally, If the load current is more than the rated current of 1.25 times of the controller 60 seconds, or load is more than the rated current of 1.5 times of the controller 5 seconds, indicator lamp (3) for red slow flash, means overload, the controller will be closed output. When the load or side of the load appear short circuit fault, the controller will immediately closed output, indicator lamp (3) flash. Appear above-mentioned phenomenon, users shall carefully check the load connection condition. Disconnect the faulty load, press a key,after 10 seconds, then resume normal work, or wait until the next day it can work normally. In the work mode for general controller state, press akey to clear overload or short circuit indication,press the key again to make recovery output.
3.Work mode Settings:
Setting method: Press the switch Settings button lasts 5 seconds, MODE (MODE) display digital LED twinkle. Loosen the button, each time you press and convert a number, until the LED display the digital reaction to the user chooses from the table model of corresponding digital then stop to press the key.Wait until LED digital not flicker to complete the set. Each time you press the button, LED digital is on, can be observed the setting value.
4.Pure light control:
When there is no sunshine, the light intensity down to initiate, after controller delay 10 minutes to confirm start signal, open load, load begin to work; When there is sunshine, light intensity rise to initiate, after controller delay 10 minutes to confirm closing output signal and then closed the output, the load stop working.
5.Optically controlled open + delay shut single time mode:
Start with the former process,When the load is working to setting time will shut the load, time setting according to the table below.
6.General controller mode:
the way can only cancel the light control,time control function,output delay and related function,keep all other function, used as a general universal controller .
7.Debug mode:
Used in system debugging use, as the same with the pure control mode, only cancel the judgment light signal control output 10 min delay, retain all other function. There is a light signal and shut off the load, if no light signal and connect the load, when installation it's convenient for checking the correctness of the installation system.
