6. Complete Installation
Once all the installation steps have been completed,
and system verification and run test results were
satisfactory, the installation can now be considered
“complete.” The Bard-Link
TM
PLC lead/lag controller
has been pre-programmed with what is widely
considered to be the most efficient operating
parameters—see Table 1.3. Further information
on exact sequence of operation and advanced
programming changes can be found in the Service
Instructions section of this manual.
WEB CARD COMMUNICATION BOARD
NOTE: A web card communications board allows
remote access, via Ethernet, to all functions of the
controller system. This is the same as if one was in
the building where the controller system is physically
installed.
Connect the Bard-Link
TM
LC5000-100 controller
Ethernet port to the existing Ethernet card in the
shelter (if applicable) using CAT 6 Ethernet cable.
5) Press ENTER key to scroll to Enable. Press UP
or DOWN arrow keys to change No to Yes. Unit
