Figure 5.15: Operation diagram for the Dahlander Starter operation mode
5.4.8 Pole Changing Starter
In this mode a Pole Changing Starter for three-phase motors with two windings is configured. The digital output
O1 is reserved (internal use) for running the motor at the low speed. The digital output O2 is reserved (internal use)
for running the motor at the high speed. The digital outputs O3 and O4 can be used according to the customer’s
needs (free).
In case of a Trip, the digital outputs O1 and O2 switch off the starting contactors, thus stopping the motor. For the
Control Unit (UC) connection diagram presented in the
Item 5.4.8.1 Connection Diagram - Pole Changing Starter on
page 5-24 , the digital inputs and outputs are configured according to the Table 5.11 on page 5-23 .
