    handwheel is rotated clockwise the output shaft of the actuator also rotates clockwise (when looking at the shaft towards the control box). On condition that the valve nut is provided with left-hand thread, the actuator closes the valve. Torque-limit switches in the actuator are set and work when the actuator is under voltage.

    – Control section which is identical for all MODACT MOK actuators, Types MOK 125 to MOK 1000 type no., with the only exception that, it differs in angular displacement of units on the base plate. In the actuator, Type No. 52 325, the unit of position-limit signalling switches is arranged as shown in Fig 1.
  • Page 10 b) Position-limit switches Position-limit switches PO, PZ switch off an electric actuator when the output shaft reaches the position for which they are set. Signalling-limit switches SO, SZ signalise the position of electric actuator output shaft. The setting of position-limit switches is carried out by positioning the output shaft into the position in whichthe set switch should switch off.
  • Page 11 Caution! The transmitter CPT 1Az must not be connected without checking the supply voltage. The transmitter outlet conductors must neither be connected to the electric actuator frame nor to the earth, not even accidentally. Before the supply voltage is checked, it is first necessary to disconnect the transmitter from the supply mains. Measure the voltage on terminals of the electric actuator to which the transmitter is connected –...

    Attention! Even after this switching off the actuator circuits are under voltage. Before any works on the actuator, e.g. change of phase sequence in the actuator terminal board, the mains voltage should be disconnected. Note: In the auto-calibration regime the regulators ZP2 version 4 perform testing of the sense of rotation and report the incorrect direction as an error.
  • Page 16 Before setting the parameters, limit switches of the actuator must be connected and adjusted and the position transmitter must be set. If moment switches are used as limit switches it is necessary to ensure that the actuator or the valve can produce required tripping moment. The parameters of the regulator cannot be set as long as the actuator shaft is in one of its extreme positions and if it is switched off by the limit switch;...
  • Page 17 By the regulation “to position” the actuator shaft is set to the position in which the input and feedback signals are equal. The regulation “to moment” means that, in setting the input signal close to limiting positions - for the signal 4 – 20 mA this is up to the value of about 4.2 mA and above 19.8 mA (these values are fix set and cannot be changed), the actuator shaft is not stopped when the input and feedback signals are equal but it goes on moving until it is stopped by action of the particular limit switch.

    Important warning: This procedure can be used in setting the parameters the setting of which cannot be changed without a connected computer (e.g. voltage level on TP input in which the regulator changes over into an error state - this can cause problems in the actuators MODACT MOK 500 and 1000 where it is necessary to set an opposite active level than the one set by the regulator manufacturer).

  • Page 19: Attendance And Maintenance

    At the end of the adjusting procedure, subject the actuator to a functional check by means of the control circuit, making sure particularly that the actuator starts correctly and is not “alive” after tripping of the respective microswitch. If this is not the case, the actuator should be immediately disconnected from the mains to avoid a damage to the electric motor and to find out the failure.

    The TEST signal can be activated by an external make contact. This signal need not be connected. From the terminals 25 and 26 (for MODACT MOK 125, 250, 500 and 1000) or 77 and 80 (for MODACT MOK 63), a failure signal can be brought out. This signal is galvanically separated from the regulator circuits.
