HI 6020IT and HI 6020JB
Junction Box and Summing Cards with or without Optional Integrated Technician

The new 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 IT, trim pots (for non-Hardy load cells) and a NEMA 4X enclosure in stainless steel, painted steel or fiberglass. The enclosure features a thick-wall design with an interior seal for a long lasting, robust wash-down installation. Each box comes with two packaged hole plugs and five cable grip fittings suitable for load cell cables with an outside diameter of 1/4 to 3/8 inches. A label is provided on the underside of the top cover to record load cell serial numbers and location.

HI 215JB
Junction Boxes and Summing Cards

Hardy C2® certified Junction Boxes contains circuitry in a waterproof enclosure that distributes the excitation voltage of up to four load points and transfers each load point’s performance characteristics and weight signals to the weight controller.

The box’s unique removable multiple connector design allows for easy isolation and troubleshooting of non-“IT” capable weighing systems. Available in NEMA 4 rated painted steel, NEMA 4X rated stainless steel or fiberglass, each box comes with two packaged hole plugs and five cable grip fittings suitable for O.D. cable of 1/4 to 3/8 inches. A label is provided on the underside of the top cover to record load point positions. A non-C2 version with trim pots is also available.

A TB10 connector allows you to connect two junction boxes together to support up to 8 load cells if the instrument supports more than four.

Hardy’s process weighing solutions are easy-to-install, configure, commission and operate. They are easy-to-maintain and save you time, money, raw materials and/or finished product.

C2® Certified Cable

Hardy C2 Certified Cable has been designed specifically for the electrically and mechanically harsh environments found in Process Weighing applications. While many process variables are transmitted at a 0-10 volt or 4-20 milliamp level, signals from load or force sensors are typically one thousand times smaller, or 0-0.010 volts.

A ten pound change on a 100,000 pound scale would correspond to a signal change of 0.000001 volts (1 micro volt). Therefore, cabling must protect against electrical noise common in the plant environment.

It is also imperative that moisture not enter the cable as it would increase capacitance and allow coupling of voltage from the excitation wires to the signal wires. The coupling of voltage causes “drifting” weight indications. Use of improper cable between even the finest load sensors and instrumentation will yield poor weighing results.

The costs and time delays of removing and replacing improper weighing system cable are prohibitive. To insure an effective weighing system, always specify Hardy C2 Certified Cable.

Configuration Software for HI 1746

This Windows-based configuration software runs on a PC connected to the Allen-Bradley(R) SLC 500 Processor via a serial link. Interfacing with the HI 1746 is easier with the WS100 software than using ladder logic, allowing the user to:

• Configure the HI 1746-WS weigh Scale Module(s)
• Calibrate the weighing system
• Configure the two module setpoints
• Read data from the C2(R) Load Sensors
• Troubleshoot the weighing system using the Integrated Technician® functions
• Read "live data" from the HI 1746-WS Weigh Scale module

Hardy’s process weighing solutions are easy-to-install, configure, commission and operate. They are easy to maintain and save you time, money, raw materials and/or finished product.
