Two-Speed Dahlander Mode Wiring Diagrams

Application Diagram with 3-Wire (Impulse) Terminal Strip Control

The following application diagram features a 3-wire (impulse) terminal strip control wiring diagram:

LS Low speed

HS High speed

1 A Dahlander application requires 2 sets of wires passing through the CT windows. The controller can also be placed upstream of the contactors. If this is the case, and if the Dahlander motor is used in variable torque mode, all the wires downstream of the contactors must be the same size.

2 The N.C. interlock contacts KM1 and KM2 are not mandatory because the controller electronically interlocks O.1 and O.2.
