The sum check has failed, likely due to interrupted writing or noise affecting NUTRUNNER settings. The manual's first action is: “Rewrite the settings to the NUTRUNNER. If the trouble still occurs after re-writing, contact our company to inform us about the environment (power noise or another noise source, etc.) around the NUTRUNNER system.”
