    4. MOUNTING TO VALVE 4 Mounting to valve This section deals with mounting the actuator on a valve, while detailing the specialities of the different version. In any case, check the actuator first for any damage. Replace damaged parts by original spare parts. DREHMO actuators can be mounted in any position.

    4. MOUNTING TO VALVE 4.2 Removal and fitting of stem nut (output drive type For output drive type A, make sure that the unbored stem nut (delivered unbored unless stated otherwise) must be provided with a thread bore in compliance with available stem prior to mounting the DREHMO actuator onto the valve.

  • Page 14: Insulating Flange

    4. MOUNTING TO VALVE 4.4 Insulating flange When using an insulating flange, heed the length of the screws used. They must not be too long: otherwise the insulating caps within the flange or even the flange as such will be damaged. We therefore recommend using studs according to DIN 938 with a depth of thread of 1 x D (refer to figure 4.4) for assembly.

    4. MOUNTING TO VALVE 4.5 Rain protection hood For HEW-RUF motors, the rain protection hood (2) is always used in combination with the fan cover (1) (siehe Abbildung 4.5). This is the responsibility of the supplier! The hood must only be disassembled at the customers’ for upward mounted shafts (protection hood points downward).

    4. MOUNTING TO VALVE 4.7 Additional settings for part-turn actuators End stops in part-turn actuator The internal end stops limit the swing angle. They protect the valve in the event of manual handwheel operation. End stop setting is generally performed by the valve manufacturer prior to installing the valve into the pipework.
  • Page 19 4. MOUNTING TO VALVE In case the dog of the hollow shaft does not engage into the respective keyway of the output drive plug sleeve, rotate the handwheel until hollow shaft engages. Slowly rotate handwheel until flange bores align, then fasten actuator using flange screws. If more than one handwheel turn is required, put the actuator to the initial position, lift it and place it again onto the output drive plug sleeve by moving one indent.
  • Page 20 4. MOUNTING TO VALVE Setting end stop CLOSED 1. Remove screw plug [3]. 2. Move valve to end position CLOSED with handwheel. 3. If the valve end position is not reached: • Slightly turn setting screw [4] counterclockwise until valve end position CLOSED can be correctly set.

  • Page 22: Connection Terminals

    5. ELECTRICAL CONNECTION • Possibly uncoated, blank sealing surfaces at the electrical connection housing parts have to be lubricated with a long-term rated synthetic grease (e.g. Klüber ISOFLEX Topas NB5051) as corrosion protection before closure. • The connecting cables must comply with the requirements in terms of electrical connection data and load (mechanical, thermal and chemical).

    6. LOCAL CONTROLS 6 Local controls The actuators are equipped with local controls containing the graphic display and display elements for local control or menu operation as well as a wireless parameterisation and diagnostic access via infra-red (IR) or Bluetooth (BT) technology. The definite version of display unit with display screen at the actuator can differ with reference to interface, display elements and display version (refer also to 6.1).
  • Page 24: Local Indication Lights

    6. LOCAL CONTROLS 6.1 Local indication lights These indication lights are used to display certain actuator states. Depending on configu- ration, both outer indication lights are used for signalling directional running indications or reaching an end position. The mid indication light is reserved as failure signal. The nature of the indicated failure can be set via actuator controls parameterisation.
