    The VEGA overspeed governor covers a wide range of speeds and can be used with instant and progressive safety gears.

  • Page 15: Working Principles

    INSTRUCTIONS: VEGA Cod: DYN35.05 Date: 25-02-2013 Check: 05 3 WORKING PRINCIPLES. The governor is of the centrifugal type and is able to work either upwards or downwards. The governor is fixed directly to the floor in the machine room or in the upper part of the well, joined by the rope to its tensing pulley located in the pit.

  • Page 18 INSTRUCTIONS: VEGA Cod: DYN35.05 Date: 25-02-2013 Check: 05 Due to the weight of the masses, the contact is protected from knocks by the part to which it is attached, therefore, the sensor cannot be damaged. The tension weight assembly can be attached to both sides of the guide rail.

  • Page 19: Overspeed Contact

    INSTRUCTIONS: VEGA Cod: DYN35.05 Date: 25-02-2013 Check: 05 As indicated, if the tightness would be less than acceptable, the bar supporting the weight and the pulley would make contact with the sensor. 3.1 OVERSPEED CONTACT. The governor has a built-in overspeed contact.

  • Page 20: Remote Tripping Mechanism (Optional)

    INSTRUCTIONS: VEGA Cod: DYN35.05 Date: 25-02-2013 Check: 05 For rated speeds above 1 m/s, the overspeed switch must be triggered at a speed above the rated speed, bellow tripping speed of the governor. The contact (2) is shown in the right picture.
  • Page 21 INSTRUCTIONS: VEGA Cod: DYN35.05 Date: 25-02-2013 Check: 05 • Solenoid fed by 24 V DC (direct current). A current of 1,1 A must be provided. • Solenoid fed by 48 V DC (direct current). A current of 0,75 A must be provided.

  • Page 22: Remote Reset Device (Optional)

    3.4 UNCONTROLLED MOVEMENT UCM DEVICE As a result of application of the new lift standard EN-81-1:1998+ A3, the Vega governor is fitted with a system that can be used to prevent uncontrolled car movement (UCM). This system is called the Parking System.

  • Page 25 INSTRUCTIONS: VEGA Cod: DYN35.05 Date: 25-02-2013 Check: 05 The distance of the governor may be shorter than that indicated, depending on the position of the locking part in the centrifugal system. Note: The Alfa parking system can be adapted to existing governors with no parking system.
  • Page 26 According to Point 9.11.7 of the Standard, uncontrolled movement must be detected by a switch. However, detecting uncontrolled movement using the Dynatech design is pointless, as the parking device remains activated when the car is at a standstill. (except in installations with door pre-opening and re- levelling).
  • Page 27 INSTRUCTIONS: VEGA Cod: DYN35.05 Date: 25-02-2013 Check: 05 Use in installations with re-levelling over 20 mm: in installations with re- levelling over 20 mm, certified switching must be used to activate the electric magnet during the re-levelling process because if it re-levels by more than 20 mm then the governor could lock and the safety gear engage.
