9.5. Installation Recommendations
Signal wires should be installed in grounded conduits and away from power or contactor wires. Instruments must be
powered only by an exclusive power supply.
System failure should always be taken into account when designing a control panel to avoid irreversible damage
to equipment or people. Installing RC filters (47R and 100nF, serial) is strongly recommended at contactor coils or
any other inductors.
9.6. Offloading and Data Visualisation
The transfer of data to a PC is accomplished by using the LogChart II software. Data can be collected anytime and saved in files
for future analysis (menu “File Save” or “File Save as”). Help can be accessed from the LogChart-II software when necessary.
Offloading data: Data offload is accomplished by clicking on the button „Offloading“
or using the LogChart-II menu. During data transfer, a status bar indicates remaining data to be transferred. Data offloading time
is proportional to the number of readings logged. At the end of data transfer, the Graph window is displayed with the downloaded
data plotted.
10.6. Graph Window
The Graph-window is a convenient tool for analysis.
It enables the logger acquisitions to be read in the form of
a “values vs. time” graph. As one moves the mouse in the
chart area, the time and the value of the records of each
channel are shown in the field located in the bottom of
the window.
Zooming in and out are implemented. It is possible to
select an area by clicking and dragging the mouse, thus
creating a zoom region, starting at the upper left position
of the region of interest.
The command „Offload acquisitions“ does not interrupt
the process of data logging and reading.
Other two windows can be easily opened:
• Acquisitions Table Window
• General information table
