4.2.2 The START Button
Pressing the START button tells LoopViewer to find all points
connected to the selected loop driver, and present them graphically in
a correct electrical sequence. Points will be presented with unique
symbols for each type, and with important information such as
Production Number (PN), and the Loop Sequence Index (LSI). In case
of illegal topologies, like multiple branch-off and loop break, these will
be presented with self-explaining symbols. For a complete list of
symbols available, see chapter 5.
As long the LoopViewer is searching for new
points on the loop, a flashlight will sweep across
the screen, and the START button will change to a
STOP button.
Each time the LoopViewer finds something irregular, it will beep, and
in some cases terminate the topology scan with an error message.
When topology is completed, the LoopViewer tests for break in the
positive wire. If there is a break, the position can be located
automatically. This will take less than 20 seconds.
4.2.3 The STOP Button
Pressing the STOP button, forces the LoopViewer to stop the topology
scan which has been started. When this button is pressed, topology
presented on screen may be incorrect. Pressing START again will
clear all points and start powering up from the beginning.
