The inputs 1 to 3 of the DMI can be connected with switches
or pushbuttons to the local control of the motor to suit the
selected motor-starter function ( a section “Motor
starter”, Page 44).
Input 4 and 5 are intended for connection of the auxiliary
switch, in order to recognise the switching state of the
circuit-breaker.
Meaning of the data inputs
The read data inputs have the following meaning:
