In the operat- ing level, the active errors appear on the display after Code 20. Note:  − If several errors have occurred, only the error with the highest priority is shown on the start screen.

  • Page 35: Applications

    Operating level 12.5 Applications The actuator's application can be selected from one of the following applications: − Positioner − PID controller − Two-step mode 12.5.1 Positioner (06 = ACTU) The actuator stem's position directly follows the input signal. 12.5.2 PID controller (06 = PID) The set point adjustable at the actuator is used to position the valve using a PID algorithm.

  • Page 36: Two-Step Mode

    Operating level 12.5.3 Two-step mode (06 = OPEN) The binary input is used for this function. When the binary input is in the active switching state, the actuator stem retracts to 100 % of the adjusted travel range. When the binary input is in the inactive switching state, the actuator stem extends to move the valve to the closed position (0 %).

  • Page 37: Configuration Level

  • Page 38: Input Signal

    Configuration level 13.2 Input signal The input signal determines the actuator stem position. Either a current or voltage signal can be applied to the input. The default lower and upper range values of the input signal are 2 to 10 V or 4 to 20 mA. The input signal range can be adapted, e.g. to achieve a plant opera- tion characteristic by connecting two or more actuators in parallel (split-range operation).

  • Page 42: Binary Input

    Configuration level 13.5 Position feedback signal The position feedback indicates the actuator stem position. The span of the position feedback signal is adjusted over the lower and upper range value parameters. Note:  − At least 2.5 V or 5 mA (depending on the input signal used) must separate the up- per and lower range values.

  • Page 43: Binary Output

    Configuration level − Next entry in information level (c11 = NEXT): If the NEXT function is selected in Code c11, the first code of the information level (i01) appears on the display as soon as binary input switching state is changed. After every new change to the active state, the next code of the information level appears (i02, i03 etc.). The display switches back to the start screen (Code 0 or Code 1 when PID controller is selected) after all the codes of the information level have been displayed due to the binary input switching or when the bi- nary input's switching state remains unchanged for five minutes.

  • Page 44: Electronic Limit Contacts

    Configuration level − Priority position (c15 = PRIO): When the priority position function is active (c11 = PRIO), this is registered at the binary output after the actuator stem stops moving. − Adopt binary input's state (c15 = BIN): The binary output reproduces the logical state of the binary input.

  • Page 46: Blockage

    Configuration level 13.10 Blockage Detect blockage (c51) The actuator detects a valve blockage by comparing the travel after the torque-dependent switch has been triggered with the travel measured on initialization. If the comparison shows that the limit switch was triggered too early, this indicates that there is a valve blockage. A blockage is indicated on the display by .

  • Page 47: Characteristic

    Configuration level Speed level (c64) The actuator stem moves to the position determined by the input signal at the selected strok- ing speed. There are two different speed levels (NORM and FAST). The transit time (c66) is calculated from the travel and the stroking speed (c65). The transit time is the time that the actuator stem needs to move through the adjusted travel.
  • Page 48 Configuration level − Linear (c71 = LIN): The travel is proportional Travel y [%] to the input signal. Input signal x [%] − Equal percentage (c71 = EQUA): The travel Travel y [%] is exponential to the input signal.
