Thyristor rotational speed regulator DSS2 T-BIS characteristic features

Smooth adjustment of the output voltage over the whole control range.

  • Bimetallic contact motor protection control. Stop of work and alarm indication.
  • Possibility to change the controller’s settings.
  • Adjustable output voltage depending on the setpoint of the keypad or an external 0-10V signal level.
  • Possibility to combine multiple controllers in systems and control them from a single point.
  • Compact, small and ergonomic design.

Thyristor rotational speed regulator DSS2 T-BIS installation

  • The DSS2 T-BIS speed controller should be mounted horizontally onthe surface of a wall or in the control cabinet (in this case theexchange of air or cooling should be made).
  • The power must be connected with non-shielded 3x1 mm² cable.
  • Steering signal must be connected by the shielded cable:
    2x0.5 mm² – for steering by DEN 20, DEN30, PLC etc.
    3x0.5 mm² – for steering by DEN 11.
  • The cable shield should be connected to G0 terminal.
  • The motor must be connected with the shielded 3x1 mm² cable.
  • The shield must be connected to the PE terminal and the motor housing.
  • Cables must be completed with sleeves.
  • To connect the wires unscrew the four screws that secure the lid and then perform the connection according to the diagram in Figure 4.
  • After connections are made, close the cover and switch the power supply on.
  • The capacitor should be connected outside of the regulator.
  • The regulator provides an additional input to TK fan protection. It must be connected by 2x1 mm² cable.
