Introduction to the HI 6020IT and HI 6020JB Summing Boxes
The Hardy HI 6020 summing box is a critical component in a weighing system that enables use of Hardy’s core
technologies - C2
®
electronic calibration and Integrated Technician
®
(IT).
Each summing box distributes excitation voltage to up to four load cells and transfers each load cell’s
performance characteristics and weight signals to the Hardy weighing instrument. A summing card with IT
allows a weighing instrument operator to switch to the summing card’s internal test circuit and diagnose the
entire weighing system from the front panel of the instrument or a remote location over the Internet. Individual
load cells can be isolated from each other for weight and voltage readings, allowing a technician or operator to
quickly and safely troubleshoot weighing system faults and anomalies.
The HI 6020 Summing box is available with a variety of options, including Integrated Technician
®
(IT) and
trim pots (for non-Hardy load cells). The UL Type 4/4X stainless steel enclosure features a thick-wall design
with an interior seal for a long lasting, robust wash-down installation. Two configurations are available, a 5-
hole version for connecting up to four load cells to a Hardy weight indicator, controller, or module; or a 6-hole
version that connects to a second HI 6020 summing box to enable up to eight load cells to be connected to a
Hardy weight indicator or controller. The HI 6020 summing box comes with four packaged hole-plugs, six
cable grip fittings, suitable for load cell cables with an outside diameter of 4.3mm to 11.4mm.
