Hardy Instruments Loss-in-Weight Rate Controller is the instrument of choice for converting a volumetric system to a Loss-in-Weight gravimetric system. It powers the scale, evaluates the weight, controls the rate of flow, automatically refills and delivers the desired amount of product at a predetermined rate. The HI 2160RCPLUS can be used as a standalone closed-loop controller, or as an intelligent front end to a PLC or DCS. The HI 2160RCPLUS is a compact, single ingredient Loss-in-Weight controller for use in a variety of applications, including auger, belt, pump and vibratory based feeders. The key ingredient to the HI 2160's ability to acurately control feed rate, is the use of WAVERSAVER® to ignore the effects of plant and process noise. WAVERSAVER® decipers the incoming load sensor signal and distinguishes noise from actual forces on the scale. As a result , the HI 2160 ignores severe plant vibration, mechanical motor noise, gear mesh vibration and agitator activity, while detecting minute forces applied to the scale. WAVERSAVER® allows the HI 2160's control algorithm to quickly correct the actual changes in rate instead of reacting to process noise. The HI 2160RCPLUS has been designed for the realities of the work place with waterproof front panel and tactile response keys. Operation is straight forward and easy to follow from the 80 character back lighted display. Frequently changed parameters are readily accessible, while one time configuration data is logically arranged in menu format. All data is protected against tampering with three user-defined security codes. Features:- Automatic Control Mode - Automatically corrects for variations in desired flow rates.
- WAVERSAVER® - Ignores plant and process vibration for more accurate measurement of feed rates.
- Manual Control Mode - Use the up and down arrows to manually control the flow rate. Convert to automatic mode when proper flow rate is achieved.
- Continuous or Batch Modes - User selectable operating modes for continuous or batch processing.
- Automatic Refill - User selectable refill points to start and stop the refill process. HI and LO alarms to detect a refill failure.
- Manual Refill - Allows for manual refill at anytime.
- Automatic Tuning (Auto Rate Calibration) - Provides the user with automatically calculated parameters or the user can manually enter their own derived values.
- Operation Displays - Single button selection of Predefined operating displays such as, Rate, Current Weight, Totalized Weight, and Batch data.
- Secure Memory Module - Provides for stored critical data to be transferred to a replacement HI 2160RCPLUS . Conveniently located on the rear panel, replacement takes only a few seconds. Does not require recalibration of the scale. Maximizes up time for the feed systems.
- Control Output - Electrically and optically isolated, user selectable 0-20 mA, 4-20 mA, 0-5 VDC, or 0-10 VDC output.
- Front Panel - 5" x 7" Waterproof when mounted in a NEMA 4 enclosure.
- Serial Communications - Bi-directional serial port (RS 232) allows reading of data and downloading of feed rate instructions.
- Hardy Link Communications - Assigns addresses to each instrument so they can share the same Serial Chain.
- Self Test - User can easily troubleshoot the controller by implementing the internal self test.
- Reports - Automatically prepares batch performance reports.
- C2 Second Generation Calibration - Electronic method for calibrating a scale.
- Remote Operation - The HI 2160RC PLUS is fitted with a bi-directional serial port, an optional Allen Bradley I/O card or Profibus Interface, which allow for remote operation of the controller.
Multiple Configuration Storage - Stores up to twelve different complete system configurations allowing fast and easy transition to a new material, auger or entire feeder. - Two Sigma - The 2 Sigma Test feature is used to measure the feed rate performance for any given feeder system. The 2 Sigma Test can be run on demand during all feed cycles.
