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 follow-
ing inputs, indicators and outputs are used:
- Circuit breaker;
input channel 2, indicator 107, controlled
by OPEN (20) and CLOSE (21) output
- Circuit breaker truck;
input channel 1, indicator 106, not
controlled
- Earth-switch;
input channel 3, indicator 104, not
controlled
The configuration commands are:
S106:1,1,1,0,0
S107:1,1,2,20,1
S104:1,0,3,0,0

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

locking 10.
The interlocking program has the following
formula:
M200:LOAD 61
M201:OUT 20
M202:LOAD 1
M203:AND 203
M204:OR 201
M205:OUT 21
