  • Page 3: Operating Conditions

    1. APPLICATION Series MODACT MONJ, MON, MOP actuators have been specially designed for adjustment of fittings and other devices for which they are suitable due to their properties and reversing rotary motion in particular. These actuators can be usedin remote control circuits. When fitted with a current transmitter, they can be used even in automatic control circuits operating in duty S4 - 25 %;...

  • Page 4: Operation Mode

    3. OPERATION MODE According to ČSN EN 60 034-1, actuators can be operated in S2 load category. The operation time at +50 °C shall be 10 minutes, the mean load torque value shall be below or equal to 60 per cent of the maximum switch off moment (M v ).

  • Page 5: Electric Connection

    Electric connection Electric connection of the actuator can be made either on the terminal boards or with a connector. Actuator terminal board The electric actuator is equipped with a terminal board for connection to external circuits. This terminal board uses screw terminals allowing conductors with a maximum cross-section 2.5 mm to be connected.
  • Page 6 The individual control units are distinguished by their functions as follows: a) Torque-limit switching unit -12- b) Signalling unit -13- c) Resistance transmitter setting machanism -14- d) Resistance transmitter of 2 x 100 ohm with mechanical position indicator, or current transmitter of 4 to 20 mA without position indicator -l5-, -15a- e) Position-limit switching unit -16- f) Anti-condensation heater -17-...
  • Page 7 Local control unit Local control serves for controlling the actuators from the site of their installation. It consists of two selector switches: one with positions "Remote control - Off - Local control", the other with positions "Opens - Stop - Closes". If required by the customer, the actuator can be fitted with a blinker that produces electrical pulses during output shaft rotation.
  • Page 8 transmitted to the tripping lever -45- or -46-. When the torque on the output shaft of the actuator reaches the value to which the torque-limit switching unit has been adjusted, the tripping lever depresses the button of the corresponding microswitch so that the electric motor is disconnected from the mains, thus stopping the actuator. Adjusting procedure of the torque-limit switching unit To adjust a different tripping torque from that adjusted at the factory, the procedure is the following: Loosen the lock nut -44- (see Fig.3) and then the lock screw -25- (for the CLOSE direction) or -26- (for the OPEN direction).

On this pinion, the motion required for driving the resistance or current transmitter is sensed.

  • Page 12 Caution! The CPT 1/A transmitter should be connected only after the supply voltage has been checked. The transmitter outlets should not be connected to the actuator frame, neither should they be earthed, even accidentally. 1) Before the supply voltage is checked the transmitter should be disconnected from the AC mains. At the actuator terminals to which the transmitter is connected, the voltage can be best measured by a digital voltmeter withan input resistance of at least 1 Mohm.

    8) Rotate the tripping rod -58- at an angle of 90°. As a result, the rod should shift out again. If this is not the case, turn the screw -59- or -56- by a small amount. Note: Turning the regulating screw -56- or -59- should be stopped at the instant of change-over. If the cams are in the position shown in Fig.9 before they are adjusted, or the cam has already pressed down the button of the microswitch, the following procedure is used to advantage: With the tripping rod -58- depressed and positioned, turn the adjusting screw -56- or -59- anticlockwise till the cam...

    9. ADJUSTMENT OF THE ACTUATOR WITH A FITTING After placing the actuator on the fitting and checking its attachment, the following adjusting procedure should be used: 1) Bring the actuator into an intermediate position by the hand. 2) Connect the actuator to the AC mains and check the correct sense of output shaft rotation by starting the actuator midway between the dead points of the working stroke for a short time.

    Actuators with oil charge Check the level of oil at least yearly and refill, if required. Oil change should be made after 500 operating hours of the actuator, but not later than after 2 years of operation. The level of oil should be as high as the filling hole. For the actuator, Grade PP 80 motor-car gearbox oil or an equivalent oil with the same properties (viscosity class 80 W, according to SAE/J306a) should be used.
