  • Page 17: Configuration Level

    4.2.3 Configuration level In the configuration level, the controller function is determined for the required control task to be solved. Access can be made to the configuration level by entering the code number. The code number is preset (factory preconfiguration) to 0 and can be modified in configuration block CCO (see page 22).

  • Page 18: Select Input Signal In

    Select input signal In Configuration block In determines the controller input signal. The following input options can be defined using selection options 0 to 5: 0 — Pt 100 – 30.0 to 150.0 °C 1 — Pt 100 –100.0 to 400.0 °C 2 —...

  • Page 23: Code Number For Servicing

    Code number for servicing Page 33 of this operating manual contains the subordinate code number for servicing which should be memorized. This special code allows, despite the entered code number CPA and CCO , values to be modified in the configuration level. In order to prevent this code number from access by unauthorized persons, either cut out or scribble over this number on page 33, making it unrecognizable.

  • Page 25: Three-Step Controller With Internal Feedback (Y = 1)

    5.1 Three-step controller with internal feedback ( Y = 1 ) The three-step controller incorporating internal feedback is selected in the configuration level with configuration switch Y = 1 . In this configuration scheme, switching output Y1 is then active when the difference between the calculated Y signal and the internal feedback is positive.

    5.2 Limit contacts ( Y = 0 or 2 ) 5.2.1 General definition Each limit contact ( Y1 and Y2 ) can, independent of one another, be assigned a value. This value can be monitored to determine whether it is exceeded in either direction. Limit contacts are as- signed using configuration block Y1 (switching output Y1 ) and configuration block Y2 (switch- ing output Y2 ).
