EB 3018 EN 1-9Safety instructions and measuresNOTICE!Incorrect control due to the formation of ice on the regulator.Medium temperatures below 0 °C may cause ice to form on the regulator, dependingon the air humidity. This may affect, in particular, the functioning of the plug or dia-phragm stem guide.Î Prevent the formation of ice by taking appropriate precautions (e.g. enclosure,trace heater etc.). The plant operator is responsible for selecting and implementingappropriate precautions.Regulator damage due to condensed glycol.In principle, the materials are also resistant to high concentrations of glycol.Nevertheless, glycol reacts when it comes into contact with metals and causes acids toform. We cannot prevent this reaction.Î Use suitable inhibitors. The plant operator is responsible for the selection and useof suitable inhibitors.Risk of regulator damage due to the use of unsuitable tools.Certain tools are required to work on the regulator.Î Only use tools approved by SAMSON.When in doubt, consult SAMSON.Risk of the process medium being contaminated through the use of unsuitablelubricants and/or contaminated tools and components.Î Keep the regulator and the tools used free from solvents and grease.Î Make sure that only suitable lubricants are used.Risk of damage to the electric actuator due to the supply voltage exceeding thepermissible tolerances.The electric actuator is designed for use according to regulations for low-voltageinstallations.Î Observe the permissible tolerances of the supply voltage.
