Application

coded transmission
Switch over from the F6 modulation to the coded transmission (description in chapter 1). For the
operating modes 3, M5A resp. 6 the coded transmission is not adjustable.
direct tripping:
This setting offers enhanced transmission security of the analog interface and should be selected
for teleprotection systems with direct tripping (use of the IFC-D). The transmission time is about
3ms longer compared with the setting <permissive tripping>).
permissive tripping:
This setting should be selected for permissive protection systems.

Output allocation

Figure 44:
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 .
A 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.
