Operation 7.4 Optional key number protection To change parameters in the configuration level, a key number can be activated in the actua- tor over Code c94. When the key number function is activated, the key number must be en- tered before the parameter setting can be changed. If a code is selected without entering a key number beforehand when the key number function is activated, LOCK is displayed and the parameter settings cannot be changed.
Operation After entering the key number, the corresponding levels are enabled for five minutes (indicat- ed by icon). The levels are automatically locked again after five minutes. Levels can also be locked again: Select Code 9 again. OFF is displayed. After confirming it by pressing , the icon disappears.
Operating level 8 Operating level The operating level is active while the actuator is in the automatic mode. In this level, import- ant information on the operation is shown, the operating mode is selected and the initializa- tion started. The other levels are accessible from the operating level. All the parameters of the operating level as well as fatal and EEPROM errors are listed in section 17.2.1.

Operating level 8.3 Initializing the actuator WARNING Risk of injury due to the actuator stem extending or retracting. Do not touch or block the actuator stem. NOTICE The process is disturbed by the movement of the actuator stem. Do not perform the initialization while the process is running. First isolate the plant by closing the shut-off valves.
Operating level 8.4 Applications The actuator's application can be selected from one of the following applications: − Positioner (POSI) − PID controller (PID) − Two-step mode (2STP) − Three-step mode (3STP) − Temperature closed-loop control upon input signal failure (POSF) Note −...
Page 46
Operating level PID controller application The set point adjustable at the actuator is used to position the valve using a PID algorithm. The input signal is used as the process variable. The PID controller is adjusted using the pa- rameters: Proportional-action coefficient Kp, Reset time Tn, Derivative-action time Tv and Op- erating point Y The proportional-action coefficient Kp acts as gain.
Operating level Temperature closed-loop control upon input signal failure application The travel follows the input signal. Upon failure of the input signal, the set point determined in the actuator by the integrated PID controller is used to position the stem. Î...

Configuration level 9 Configuration level The actuator is adapted to its control task in the configuration level. The codes in this level have a 'c' prefix to identify them. All the parameters of the configuration level are listed in section 17.2.2 on page 83. 9.1 Activating and setting parameters Changing settings in the configuration level Activate the configuration level...
Configuration level 9.2 Input signal The input signal determines the actuator stem position. Either a current or voltage signal can be applied to the input depending on the configuration in Code c01. 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.
Configuration level − Internal positioning value (c32 = INT): The actuator stem moves to the position specified in Code c33 upon failure of the input signal. − Last position (c32 = LAST): The actuator stem remains in the last position that the valve moved to before failure of the input signal. The error message is reset and the actuator returns to closed-loop operation if the input sig- nal moves within 0.2 V or 0.4 mA of the lower range value.
Configuration level 9.4.2 Operating direction increasing/decreasing − End position guiding (stem retracts) (c35): The actuator stem moves the valve to the low- er end position if the input signal reaches the value entered in this code. Setting c35 = 100.0 % causes this function with a retracting actuator stem to be deactivated. −...
Configuration level 9.6 Binary input The function of the binary input can be configured as required. Code c12 is used to deter- mine the switching state for the active function. c12 = NINV: the binary input is active when the input terminals IN 4 +/IN 4 – are connected with each other. c12 = INV: The binary in- put is active when the connection between the input terminals IN 4 +/IN 4 –...
Configuration level 9.7 Binary output The binary output is a floating contact. The function and switching state of the binary input can be configured as required. − Inactive (c15 = NONE): No function is assigned to the binary output. − Error indication (c15 = FAIL): when an error ( icon) is registered, the error message is issued at the binary output.
Configuration level 9.8 Electronic limit contacts The electronic limit contact can be triggered by the actuator stem position exceeding or fall- ing below an adjustable switching point. − Triggered when the position exceeds the switching point: The limit contact is activated when the actuator stem position moves beyond the switching point. The limit contact is deactivated when the actuator stem moves below the switching point plus hysteresis.
Configuration level − Fixed positioning value (c43 = FIX): The actuator switches to the manual mode and moves the actuator stem to the Fixed positioning value for restart. − Stop in manual level (c43 = STOP): The actuator switches to the manual mode and sets the last positioning value to be the same as the manual positioning value. Code Description Adjustment range...
Configuration level 9.11 Travel Limited travel range (c63) The Limited travel range parameter determines in % how far the actuator stem can move at the maximum. The rated travel (c61) acts as the reference. When c63 = 100.0 %, the travel range is not limited. Code Description Adjustment range...
Configuration level 9.12 Characteristic The characteristic expresses the relation between the input signal and the actuator stem's po- sition. − 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.

Configuration level 9.14 Plausibility error Due to an invalid combination of interacting parameters in the configuration level, a plausi- bility error arises which is indicated by PLAU blinking on the display. A correction of the in- teracting parameters resets the error message. Causes of plausibility error −...

Configuration level − Invalid limits of process variable range (Code c88/c89): The set point (Code c81) is within the range defined by the lower (Code c86) and upper adjustment limits (Code c87). The lower limit of process variable range (Code c88) has a greater value than the lower adjustment limit (Code c86) or the upper limit of process variable range (Code c89) has a lower value than the upper adjustment limit (Code c87).
Information level 10 Information level In the information level, all the actuator data important for closed-loop operation are dis- played. Codes of the information level have an 'i' prefix to identify them. All the parameters of the information level are listed in section 17.2.4 on page 88. 10.1 Activating parameters Activate the information level 1.
Service level 11 Service level The service level contains detailed information on the actuator and its operating state. Addi- tionally, various test functions can be performed in this level. Codes in the diagnostic level have a 'd' prefix to identify them. All the parameters of the service level are listed in section 17.2.5 on page 89.
Service level 11.2 Starting zero calibration WARNING Risk of injury due to the actuator stem extending or retracting. Do not touch or block the actuator stem. The actuator stem moves to the 0 % end position. Following this, the actuator changes to closed-loop operation and moves the actuator stem to the position defined by the input sig- nal.
Service level 11.5 Loading default settings All the parameters of the configuration level can be reset to their default settings (WE). Code Description Adjustment range Load default settings in actuator 11.6 Testing the display All the segments of the display are shown during the display test when a display functions properly.
Communication level 11.7 Measuring the transit time WARNING Risk of injury due to the actuator stem extending or retracting. Do not touch or block the actuator stem. NOTICE The process is disturbed by the movement of the actuator stem. Do not perform the initialization while the process is running. First isolate the plant by closing the shut-off valves.

Malfunctions 15 Malfunctions 15.1 Error messages Active errors are added at the end of the top operating level. An error is indicated by the display blinking and alternating between the start screen and the indicated error with the error icon. If several errors have occurred, only the error with the highest priority is shown on the start screen.
