NOTE
When connecting two IT Junction Boxes together to connect 8 load points, you must
run an
external 5 Volt DC power supply if you will run C2 cabling a long distance.
You cannot use a
higher voltage power supply due to over voltage damage to your
Hardy controller. For more
information, visit the Hardy Knowledgebase and search
under external excitation voltage.
Excitation monitor is the current draw on the excitation voltage from the weight
controller. When using an external power supply the excitation monitor will not
function
properly. The internal excitation voltage is not being used, therefore no
current draw,
and the excitation monitor will improperly report a failure

NOTE
When connecting a Hardy Summing Box to a HI 6610 WPM you must remove the two
factory
installed jumpers on pins 1 & 2 and on pins 5 & 6 on the module and install
C2 and sense
wires. C2 wires carry the commands for Integrated Technician and the
C2 calibration
information.
