Output allocation

Figure 44: Output allocation for operating mode Mode M5A

In the SWT 3000 system every possible combination of binary inputs is permanently assigned a

protection frequency depending on the operating mode (Mode 1 to Mode 5A) and the function Un-

blocking “On“ or “Off”.

At the receive end every protection frequency can be assigned to one or more signal outputs

(BA1 to BA4) with the output allocation for the operating mode

Mode 3a and 5A.

In digital operation it is also possible to assign the outputs to the activated binary inputs for the

operating mode

Mode 5D.

preset allocation can be loaded with <Default>. All allocation settings are deleted with <Clear>.

The setting made can also be stored as files with <Save> and called up again with <Load>.

This assignment is

permanently set for the operating modes Mode 1, 2, 3 and Mode 4 and can-

not

be changed with the output allocation.
