First, set two basic parameters, the lower limit voltage V1 and the upper limit voltage V2<br/>1. Press the setting button once to display &quot;F1&quot; flashing<br/>2. Press the setting key for the second time to display the default V1 value &quot;XX. X&quot; flashing. Press the &quot;Plus&quot; or &quot;Minus&quot; control keys to adjust the lower limit parameter V1<br/>3. Press the setting key for the third time to display the default V2 value &quot;XX. X&quot; flashing. Press the &quot;Plus&quot; or &quot;Minus&quot; button to adjust the upper limit parameter V2 (at this time, if V1 is greater than V2, it will be displayed. &quot;ERR&quot; error prompt, parameter needs to be changed, and it is necessary to keep V1 less than V2 as normal)<br/>4. Press the setting key for the fourth time, and the parameters will remain permanently and exit<br/>5. Press the &quot;Minus&quot; button for 3 seconds in standby mode to turn off the display, and press it again for 3 seconds to turn on the display. Designed to reduce power consumption<br/>Function Description<br/>1. F-1 charging monitoring: When the measured voltage is lower than the voltage V1, the relay is closed, and when the voltage is higher than V2, the relay is disconnected<br/>2. F-2: Discharge monitoring: When the measured voltage is higher than the voltage, V2 relay is closed, and the voltage is lower than V1 relay is disconnected<br/>3. F-3: Off range pull-in: When measuring voltage, the relay is disconnected between V1 and V2, and other states of relay pull-in are introduced<br/>4. F-4: In range pull-in: When the measured voltage is between V1 and V2, the relay pulls in and disconnects in other states<br/>5. F-5: Fixed point monitoring: When the measured voltage is higher than V1, the relay is closed and lower than V1, the relay is disconnected<br/>6. F-6: Fixed point self-locking monitoring: When the measured voltage is higher than V1, the relay will remain engaged until manually powered off<br/>7. F-7: Fixed point pulse monitoring: When the measured voltage is equal to V1 (up and down floating 0.1V) each time, the relay outputs a jog signal<br/>8. F-8: New feature, voltage error correction, range ± 5.0V.<br/>Supplementary Setting Method<br/>After setting the F-1, all other functional parameters are set using the F-1 parameters. After pressing the setting button, F-1 will flash, and then press+or - to adjust the function number. After reaching a certain function number, press the setting button again and it will be OK. After pressing the setting button, F-1 will flash, and then press+or - to adjust the function number. After reaching a certain function number, press the setting button again and it will be OK.</p><p><span style="font-size:20px"><strong>Package include:</strong></span><br/>Relay module *1<br/><br/></p></div></div><p><br/></p>
