Default configuration and interlocking 10 is
selected by giving variable S100 the value 10.
The other parameters have the values given in
the chapter "Default values of the parameters".
Configuration
The configuration has three objects, a circuit
breaker, a circuit breaker truck and an earth-
switch. The close state is indicated with green
colour and the open state with red colour. This
default is the same as default 1, but the colours
of the object indicators are reversed. The fol-
lowing inputs, indicators and outputs are used:
- Circuit breaker;
input channel 2, indicator 107, controlled by
outputs OPEN (20) and CLOSE (21)
- Circuit breaker truck;
input channel 1, indicator 106, not controlled
- Earth-switch;
input channel 3, indicator 104, not controlled
The configuration commands are as follows:
S106:1,1,1,0,11
S107:1,1,2,20,1
S104:1,0,3,0,0

Interlocking
The following rules apply for interlocking:
- The CB can always be opened.
- The CB can be closed if if the CB truck is in
the service position and the earth-switch is
open or if the CB truck is in isolated position.
