Voltage Monitoring Module, A30-U1 DC 0-99.9V Delay Relay Controller Board for Overvoltage Undervoltage Control Voltage Detection

1. The screen automatically displays the current measured voltage value after power on. Press the SET button to enter setting mode and first bit will continue to flash. The first set of parameters is the voltage value upper limit (Adjustment range is 0 to 9). Press the ENTER button to set the first bit value. Press SET button again to select the next bit, press ENTER button to change the value.

2. Press the SET Button the Third Time to Select the Last Bit. Then the first parameter "Upper Limit Voltage Value" was set. Press The SET Button At The 4th Time To Set The Next Parameter Value Lower Limit Voltage In The Same Methods. Note: Its value must be lower than the upper limit voltage value.

3.The third parameter is to set the voltage check value. Its adjustment range is -0.5V to 0.5V. The 4th parameter is to set the remaining time value of the display screen automatically turns off. Its Adjustment Range Is D-0~D-9, Which Means After 1-9 Minutes, The Screen Will Turn Off. Note: d-0 means the screen will stay on all the time. The 5th parameter is used to define the triggering state of the relay 'ON H' or 'ON L'.

4.'ON H': The relay output turns on if the current measured voltage value is greater than the upper limit voltage value. It can be applied to battery discharge mode. 'ON L': the relay output activates if the voltage value measured current is lower than the lower limit voltage value. It can be applied to battery charging mode. Automatically enter the detection state after setting parameters and the screen stops flashing.
