Module will automatically turn off the charging time control function. And flashing 'H:ER' on screen to remind users that time parameter settings are unreasonable. Press any key to stop flashing.Note: Time format: 00:59 (00 is hours, 59 is minutes) The maximum time is 99:59which is about 100 hours.3) UART communication and parameter settingsThe system supports UART data upload and parameter setting functions (TTL level);UART: 115200, 8, 1NO.CommandFunction1ONRelays Enable2OFFRelays Disable3StartStart data upload4StopStop data upload5ReadRead the parameter setting6dw10.0Set volt-LI: 'dn'7up20.0Set volt-HI: 'UP'8xx:xxSet the charge time 'OP'. 00:00 is used to stop charge time control functionData upload message format:Battery voltage + battery percentage + charging time + charging status12.0V, 020%, 00:10, OPSet Parameter:1) LCD will display 'SET' after enter set parameter menu by long press button 'SET'.2) Switch the set parameters by short pressing button 'SET'.3) Set parameter value by long or short pressing button 'UP' and 'DOWN'.4) Repeat step 2 and step 3 if need to set other parameters.5) Automatically save and exit the setup menu by long press button 'SET' after set all parameters.Button Description:In the normal display interface:1) Display the currently set parameters when short press button 'SET';2) Switch display charging percentage and charging time when short press button 'UP';3) Enable Relay ON or OFF when short press button 'DOWN'. Relay will OFF and display OFF if disable relay.4) Set the status of the LCD backlight(L-P) when long press button 'UP'.OFF: The backlight will keep bright.ON: Backlight will be automatically turned OFF after 5-10second.5) Long press 'SET'button to enter the parameter settings menu.Calculation Voltage Percentage:voltage percentage = battery voltage/(volt-HI minus volt-LI)Additional Features:1) Charging time recording function: The product will record a full charge time when the charging time control is not turned on. Flashing shows the charging time when entering the time display interface. The data will be emptied when exit the time display interface or the next charge is turned on (the relay is turned on)2) Automatic parameter detection: The system will flash 'ERR' to indicate the reminder when the parameter is set and exiting but Lower limit voltage 'dn' more than Upper limit voltage 'UP'.3) Battery connection detection: This product is attached to the battery. If the battery is not connected, the system will display 'nbE' on the lower line to remind you;FAQ:1) What is the control voltage range? What is the applicable battery range?Control voltage range is DC 6V-60V. But battery voltage max is 48V. Because the voltage of 48V battery is 60V after fully charged.2) The relay is automatically turned on and off continuously after power on and flashing light?This is because your charging current is too large or the battery capacity is too small that cause the battery voltage to immediately exceed the Lower limit voltage 'dn' value and then relay will OFF. But the voltage drops quickly to the Lower limit voltage 'dn' after Relay OFF a
