The relay is open because the programmed voltage thresholds have not been reached.
: The load stays ON only when voltage is between 11.0V and 13.0V. If voltage goes outside this range, the relay activates and disconnects the load.
In P1 mode, use and DEC (-) to reach the desired voltage. Set Stop Voltage
The module features two tactile pushbuttons used to set the Upper Voltage limit (U₁) and Lower Voltage limit (U₂). A. Setting the Lower Limit (U₁) - Disconnect Voltage Xh-m608 Manual
| Problem | Likely Cause | Solution | |---------|--------------|----------| | Display shows --- | No battery connected or voltage < 10V | Check battery voltage and wiring | | Relay chatters | Loose connection or insufficient current | Tighten terminals; ensure battery > 9V | | Does not stop charging | P2 set too high or charger voltage never reaches P2 | Lower P2 or adjust charger output | | Stops charging immediately | P1 and P2 too close | Increase difference (e.g., 12.0V / 14.0V) |

⚠️ Disconnect all live batteries and power sources before attempting installation to avoid accidental shorts or terminal sparks.
Connect the to the module's power inputs.
Connect your (appliance, inverter, light) to the OUT+ terminal. Connect your Load Negative (-) to the OUT- terminal. Troubleshooting Common Issues The display reads "ERR" In P1 mode, use and DEC (-) to reach the desired voltage
: Up to 30VDC or 220VAC (Isolated dry contacts)
Always handle the board with care to avoid damage from electrostatic discharge (ESD).
