If there is ongoing beeping in high precision laser cutter closed loop refrigeration chiller unit, that means some kind of fault occurs. In addition to beeping, there is also an error code indicating on the temperature display. Different error code suggests different fault. For example, if E1 is on the temperature display, that means ultrahigh room temperature alarm is triggered. In this case, pressing any button on the display would stop the beeping. But the E1 error code won’t disappear until the refrigeration laser water chiller is placed at well ventilated spot with below 40 degree Celsius ambient temperature.
