HI 1769-FC

The HI 1769-FC Feeder Control module for CompactLogix™ and MicroLogix™ 1500 PLCs

HI 1769-FC CompactLogix and MicroLogix Weigh Feeder

The HI 1769-FC Feeder Control module automatically calculates and adjusts tuning parameters typically required to maintain desired flow rates in a dispensing or filling system.

It is a microprocessor-based CompactLogix™ and MicroLogix™ 1500 plug-in module used with the PLCs Rack I/O in a variety of material-flow applications, such as auger, belt, and vibration-based feeders. It can be operated in batch, automatic, or manual mode.

Worry Free Operation

The HI 1769-FC feeder control module will watch your process and notify you of problems. Prompts on your system’s HMI display and PLC alarm relay outputs occur with tolerance errors and other failures.

Algorithms contained in the HI 1769-FC compare user defined flow rates to the actual flow rates by continuously monitoring changes in the system weight over short intervals of time; the 1769-FC then calculates the adjustments necessary to achieve the user defined rate and instructs the PLC to adjust the speed of the feeding or dispensing device.

HI 1769-FC Feeder Controller Weigh ModuleThe 1769-FC updates 100 times per second and is capable of 8 million counts of resolution, enabling the instrument to precisely determine target flow rates and tolerate large "dead" loads. The HI 1769-FC incorporates Hardy Process Toolbox core features WAVERSAVER®, C2® electronic calibration and INTEGRATED TECHNICIAN® (IT).

Multiple Feeder Control

The HI 1769-FC is a powerful building block when it comes to multiple feeder systems. It can be secondary to other process inputs through the CompactLogix™ or MicroLogix™ 1500 processor.

Automatic Weight and Rate Calibration

A five-point auto rate calibration automatically allows the module to calibrate itself to the characteristics of the feeder and the material being fed. This allows for a higher feed accuracy over a broader range of feed rates.

Hardy Process ToolboxHardy Process Toolbox

The Hardy Process Toolbox is a set of productivity tools that support industrial weighing functions. Each tool saves time, increases accuracy, improves efficiency or reduces risk in process weighing applications, including WAVERSAVER® to eliminate vibration, C2® electronic calibration and Integrated Technician® to name just a few.

The HI 1769-FC features the following Toolbox technologies:

WAVERSAVER® Vibration Eliminator
Hardy's WAVERSAVER core technology eliminates the effects that surrounding vibration has on the scale weight signal, providing only true data for fast, accurate weight reading.

C2® (or eCAL) Electronic Calibration
The Hardy C2® (or eCAL as it is known in China) core feature provides quick and easy electronic calibration of a weighing system without the need for heavy test weights.

Hardy's INTEGRATED TECHNICIAN (IT) core feature helps you troubleshoot your weighing system and diagnose problems from the front of the instrument or via the PLC. These tests display system weights, voltages, and pass/fail displays to help isolate a problem to the instrument, cabling, or sensors, helping to reduce maintenance costs.

FEED-MASTER is a set of software controls designed to control volumetric and gravimetric feeders.
