Stop Light (usually Red): Illuminates when the relay is open (power is cut off).
Once powered, the screen will light up. Here is how to program your weld time.

Based on common support requests regarding the XH-M608 manual, 80% of user errors occur during wiring. Follow this schematic in text form. Xh-m608 Manual
The is a versatile, programmable, digital battery charge and discharge controller module . Operating across a wide DC 6–40V input range , this module functions as an automated supervisor to prevent dangerous overcharging and over-discharging in lead-acid, lithium, and AGM batteries. It achieves this by using an onboard microcontroller to actively sample real-time voltage and toggling an isolated 10A SPDT relay to connect or disconnect a battery charger or an external load. Technical Specifications
Employs a relay output to simplify the control of external chargers or loads. Programming Guide (Menu P0–P4) The module is programmed using three buttons: . To enter the settings, long-press Description Operating Mode Sets the module to (Voltage detection), (Charge mode), (Discharge mode), or (Voltage limit/monitoring). Lower Limit Voltage
The is a highly versatile, programmable battery charge and discharge controller module designed to manage 12V to 24V battery systems . It functions as a voltage-controlled relay, automatically connecting or disconnecting a charger or load based on precise voltage thresholds you set. Stop Light (usually Red): Illuminates when the relay
The voltage limits are set too close together. When a load turns on, the battery voltage naturally drops slightly, causing the module to turn back off instantly.
The module supports four primary operating modes, selectable via the parameter: Relay Logic U (Voltmeter) Displays current voltage only. Relay stays P (Protection) Voltage range protection. only within the set range. C (Charging) Automated battery charging. Relay turns at lower limit and at upper limit. F (Discharging) Automated battery discharging. Relay turns at upper limit and at lower limit. Programming Guide To configure the module, use the Enter Menu: Long-press the button to enter parameter selection. buttons to scroll through parameters (P0–P4). Adjust Values: Short-press to select a parameter, then use to change the value. Long-press or wait 5 seconds for the module to save and exit. Parameters Defined: Lower voltage limit (e.g., 10.5V for a 12V battery). Upper voltage limit (e.g., 14.4V for a 12V battery). Timer (minutes). Set to
