4.1 Flow of Site Adjustment
When the task of site adjustment is subdivided into smaller tasks as shown in the figure below, the
tasks can be broadly grouped into four steps. The benefit of following these for steps when carrying
out the tasks of site adjustment is that if troubles do arise, it will be clear which step caused the
problem. This makes it easier to solve problems and this results in a more efficient execution of site
adjustment tasks.
(Step 2 can be skipped when not using the PLC.)
Carry out site adjustment, by following the step by step instructions shown below.
