14.1.1 Example 1: Change-over from terminal control to keypad control
•
The control is executed primarily via the I/O terminals: Switch S1 serves to start and stop
the motor.
•
Switch S2 serves to oponally change over to local keypad control. In case of acvated key-
pad control, the motor can only be started via the keypad key. However, the condion
is that switch S1 is closed.
•
If switch S1 is opened again or the keypad key is pressed, the motor is stopped (irre-
specve of the acve control source).
