Safety PrecautionsBefore using this product, the user is requested to read the following precautions carefully to ensure thesafety. Safety precautions must be taken by every user to prevent accidents.The safety requirements are classified into "warning" and "caution" according to the following interpretations:WarningCautionSuggesting that the user's mishandling canresult in personal death or serious injury.Suggesting that the user's mishandling can resultin personal injury or damage to the property.WARNING Over-temperature Protection“Any control system design should take into account that any part of the system has the potential to fail”.“For temperature control systems, continued heating should be considered the most dangerous condition,and the machine should be designed to automatically stop heating if unregulated due to the failure of thecontrol unit or for any other reason”.The following are the most likely causes of unwanted continued heating:1) Controller failure with heating output constantly on2) Disengagement of the temperature sensor from the system3) A short circuit in the thermocouple wiring4) A valve or switch contact point outside the system is locked to keep the heat switched on.In any application where physical injury or destruction of equipment might occur, we recommend the installationof independent safety equipment, with a separate temperature sensor, to disable the heating circuit incase of overheating.The controller alarm signal is not designed to function as a protective measure in case of controller failure.– 3 –
