  • Page 57 Start-up and configuration 7.5.2 Modbus RTU module The electric actuator can be connected to a control station over Modbus and can be config- ured using TROVIS-VIEW. For this purpose, the actuator with firmware version 3.10 and higher can be fitted with an RS-485 module. Various communications protocol (SSP or Mod- bus RTU slave) are used for various functions. For Modbus RTU communication, the RS-485 module (order no. 1402-1522) must be insert- ed into the actuator. Î Excerpt from Modbus list: see Annex A. Protocol − Setting: automatic The SSP and Modbus RTU protocols are automatically detected: the interface parameters are fixed internally to Baud rate 9600 bit/s, 8 data bits, no parity, 1 stop bit. The electric actuator can exchange data with TROVIS-VIEW or the control station without switching over.

  • Page 91 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. Code Description Adjustment range...
  • Page 92 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 93 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 94 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 See Fig. 16-1. − Increasing/increasing (c42 = >>): The actuator stem retracts as the input signal increases. − Increasing/decreasing (c42 = <>): The actuator stem extends as the input signal increases. Actuator stem extended −...

Setting c35 = 100.0 % causes this function (end position guiding: valve open) with a retracting actuator stem to be deactivated.
  • Page 96 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. Note −...
  • Page 97 Annex A (configuration instructions) − Next entry in information level (c11 = NEXT): If the NEXT function is selected in Code c11, the first code of the information level (i01) is displayed 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 returns to the start screen after all the codes of the information level have been displayed due to the binary input switch- ing or when the binary input's switching state remains unchanged for five minutes.
  • Page 98 Annex A (configuration instructions) − Adopt binary input's state (c15 = BIN): The binary output reproduces the logical state of the binary input. − Indicate manual mode (c15 = MAN): The binary output is active when the manual mode (MAN) is active (Code 2) or the manual level in TROVIS-VIEW is active.

  • Page 99 Annex A (configuration instructions) Note An activated limit contact remains permanently active if the switching point is smaller or larg- er than the hysteresis. This limit contact can only be deactivated by a restart (see the 'Opera- tion' section) or by resetting to NONE (c24, c27). Code Description Adjustment range...
  • Page 100 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 101 Annex A (configuration instructions) 16.11 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 Rated travel Read only Limited travel range 100.0 % 10.0 to 100.0 % 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 102 Annex A (configuration instructions) 16.12 Characteristic The characteristic expresses the relation between the input signal and the actuator stem's po- sition. Y in % − Linear (c71 = LIN): The travel is proportional to the input signal. X in % Input signal Y in % − Equal percentage (c71 = EQUA): The travel is exponential to the input signal.
