Description:

The TMS7 can be configured for control of dual speed Dahlander type motors. In this application the TMS7 is employed with a High Speed
contactor (K1M), Low Speed contactor (K2M) and a Star contactor (K3M).

On receipt of a High Speed start signal the High Speed contactor (K1M) and Star contactor (K3M) are closed. The TMS7 then controls the
motor according to the Primary Motor Parameter set. (Function Numbers 1~9)

On receipt of a Low Speed start signal the Low Speed contactor (K2M) is closed. The relay contact across Input A is also closed causing
the TMS7 to control the motor according to the Secondary Parameter set (Function Numbers 80~88).

Function Settings:

-

Function 23.

Relay Output C Functionality

= 0 (Assigns the Trip function to Relay Output C)
