Product Parameter：Voltage: DC12VRelay contact maximum current: 12ADetection voltage range: 0-99.9VQty:2pcs Shipping List:2X Relay modules Parameter setting instructions:Turn on the power to display the voltage into the standby state, first set two basic parameters, the lower limit voltage V1 and the upper limit voltage V2 1. Press the setup key once to display "F1" flashing. 2. Press the setup key for the second time to display the default V1 value "XX.X" blinking. Press the "plus" button or "minus" control key to adjust the lower limit parameter V1. 3. Press the Setup key for the third time to display the default V2 value "XX.X" blinking, press the "plus" key or "minus" key to adjust the upper limit parameter V2 (at this time, if the V1 participation parameter is greater than V2, it will be displayed). X" blinks, press the "plus" button or "minus" button to adjust the upper limit parameter V2 (if V1 participation parameter is greater than V2, it will be displayed. "ERR" error message, need to change the parameter, be sure to keep V1 less than V2 as normal) 4. Press the Setup button for the fourth time, the parameter will be kept permanently and quit. 5. In standby mode, press the "minus" button for 3 seconds to turn off the display, and press it again for 3 seconds to turn on the display. Designed to reduce power consumption Function Description:1.F-1 Charging monitoring: when the measured voltage is lower than the voltage V1, the relay will absorb, and the voltage is higher than V2, the relay will disconnect. 2.F-2: Discharge monitoring: when the measured voltage is higher than the voltage V2 relay is activated and the voltage is lower than V1 relay is disconnected. 3. F-3: Out-of-range engagement: when the measured voltage is introduced between V1 and V2, the relay is disconnected. 4. F-4: Intra-range engagement: when the measured voltage is introduced between V1 and V2, the relay is engaged and the other status relays are disengaged. 5. F-5: Fixed-point monitoring: Relay is activated when the measured voltage is higher than V1 and deactivated when it is lower than V1. 6.F-6: Fixed-point self-locking monitoring: when the measured voltage is higher than V1 relay is engaged and remains engaged until manual disconnection. 7.F-7: Fixed-point pulse monitoring: when the measured voltage is equal to V1 every time (floating up and down by 0.1V), the relay outputs an actuating signal. 8.F-8: New function, voltage error correction, range ±5.0V. Setting method added:In F-1 set up, set up after the other functions of the parameters are used in F-1 set parameters. After pressing the setup key with blinking F-1, then press + or - to adjust the function number, and then press the setup key again after adjusting to a certain function number, then it is OK. After pressing the setup button, the F-1 blinks, then press + or - to adjust the function number, and then press the setup button again after adjusting to a certain function number, then it is OK.
