The first thing tested is the loop
integrity.
If there is a broken wire or it is not
plugged into a socket, a warning
message ‘Wire connection issue’
appears below the top bar.
In addition it will tell you which wire
is carrying the fault. The message will
continue as appropriate with on of these
statements:

‘minus (-) wire’
The fault should be investigated and
corrected before continuing.
