Their switching po- sitions are changed independently from one another by continuously adjustable cam disks. The floating contacts can be used as either make or break contacts to influence the tasks of control equipment. The installation and adjustment of the me- chanical limit contacts is described in the 'In- stallation' section.

  • Page 77 Malfunctions − Invalid value for lower range value during fast configuration (FCO): Lower range value (Code c02) and active detection of input signal failure (Code c31 = YES) are a valid combination. However, a plausibility error arises if an input signal from 0 to 20 mA or 0 to 10 V is selected through fast configuration (FCO). Recommended action: Set Code c02 to a value ≥1.0 mA or ≥0.5 V. − Invalid set point (Code c81): The set point (Code c81) is not within the range defined by the lower (Code c86) and up- per adjustment limits (Code c87). Recommended action: Set the set point (Code c81) or the adjustment limits (Code c86/ c87) so that the set point is within the adjustment limits.

    Annex A (configuration instructions) 16 Annex A (configuration instructions) 16.1 Key number 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.

  • Page 94: Input Signal

    Annex A (configuration instructions) icon indicates that the configuration level is enabled to Î change the parameter. 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. Customized key number In addition to the fixed service key number, a customized key number can be used. It is en- tered in the same way as the service key number in Code 9 and is set by default to 0000. You can change the customized key number in Code c92. The service key number becomes effective if the customized key number is deactivated in Code c91.
  • Page 95 Annex A (configuration instructions) Example: Two valves regulate the process medium in one common pipeline to achieve a large rangeability. One valve opens with a 0 to 5 V input signal, while the second valve also opens when the input signal increases further (5 to 10 V) and the first valve remains open. The two valves close in the reverse order. Note At least 2.5 V or 5 mA (depending on the input signal used) must separate the upper and lower range values.

  • Page 96: Direction Of Action

    Annex A (configuration instructions) Note The input signal must be ≥0.5 V or ≥1 mA to be able to detect a malfunction. 16.3 Direction of action Î Refer to Fig. 16-3. − Increasing/increasing (c42 = >>): The actuator stem retracts as the input signal increases. −...

Setting c35 = 100.0 % causes this function (end position guiding: valve open) with a retracting actuator stem to be deactivated.

  • Page 98: Position Feedback Signal

    Annex A (configuration instructions) 16.5 Position feedback signal The valve position feedback indicates the valve travel. It uses an analog signal issued at the terminal U OUT or I OUT. The span of the position feedback signal is adjusted over the lower and upper range value parameters.

  • Page 102: Blockage

    Annex A (configuration instructions) 16.10 Blockage Blockage detection (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 the icon.
  • Page 103 Annex A (configuration instructions) Speed (c64) The actuator stem moves to the position determined by the input signal at the selected stroking 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.
