3.9.15 CB Trip Signal

The signal MAIN: CB trip internal is issued if the following conditions are
simultaneously met:

The input configured for “tripping” is set to a logic value of '1' or the selected trip

command of the C232 is present.

At the input configured for “CB trip” a logic value of '1' is present.

The CB trip signal of an external device can also be signaled. For this task, one input
needs to be configured for “CB trip enable ext.“, a further input for “CB trip ext.“.
