9.TROUBLE SHOOTING
4.a) Assume that the indicator lamp blinked yellow in test a) above. Reset all connections to their original positions. Then disconnect A2. Connect a new loop wire to A2. Connect the other end of this new loop wire somewhere at the centre of
the installation.
If the indicator lamp is green or flashing yellow, then the break is somewhere in the wire between the disconnected end to the point where the new wire is connected (thick black line in the illustration below).
In that case, move the connection for the new wire closer to the disconnected end (roughly at the middle of the suspected wire section) and check again if the indicator lamp is green or flashes yellow.
