Page 8: Types Of Warning
Types of warning DANGER DANGER Warning of a dangerous situation that will result in death or serious injury. WARNING Warning of a dangerous situation that may possibly result in death or serious injury. CAUTION CAUTION Warning of a situation that may result in minor or moderate injury. ATTENTION ATTENTION Warning of a situation that will result in damage to property or the environment. -
Page 9: Specialist Terms/Abbreviations
Specialist terms/Abbreviations Here, we explain some abbreviations, specialist terms, etc., which are used in this Manual. Controller P component The P component enables the controller gain to be adapted to the controlled system. The greater the P component, the more strongly the controller will react to deviations. I component The I component, or reset time Tn, ensures that control can take place without permanent deviation. -
Page 10: Specialist Terms/Abbreviations
Specialist terms/Abbreviations Dead zone The effect of the dead zone is that the manipulated variable no longer changes when the setpoint plus/ minus dead zone in % is reached. Example using level: Setpoint = 60%. Dead zone = 5%. Setpoint [dead ] = 3%. 58.5% ... -
