• 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 Two Sigma Test feature is used to measure the feed rate performance for any given feeder system. The Two Sigma Test can be run on demand during all feed cycles.

The prerequisite of effective feeder control is accurate measurement of the process. Hardy Instruments` exclusive WAVERSAVER technology ignores vibration and mechanical noise in feeders and the plant environment. There`s no need for mechanical contraptions to dampen vibration because WAVERSAVER intelligently deciphers true weight data from the load cell signal. All of this is done in a fraction of a second, allowing the HI 2160RCPlus`s control algorithms to be precise and responsive. With 1,000,000 counts of display resolution, the HI 2160RCPlus can monitor even minute weight changes in systems with high dead loads.

Hardy Instruments’ C2, Second Generation Calibration, feature allows you to electronically calibrate your feeding system immediately after installation, eliminating all of the problems associated with test weights. Each C2 certified load sensor contains information detailing its unique performance characteristics. The HI 2160RCPlus uses these characteristics to automatically calibrate the scale without the need for test weights, even with material placed on the scale.

A five-point Auto Rate Calibration automatically allows the HI 2160RCPlus to tune itself to the feed characteristics of the feeder and the material being fed by it. It will also display a percent deviation, if any, at all five points. This allows for a higher feed accuracy over a broader range of feed rates.

Need to change your material, an auger or the complete feeder? With the HI 2160RCPlus, once you have done your setup and calibrations, you simply store them away in its twelve dedicated, on board memory locations. When you make a change, you just retrieve the required configuration and continue your process. There is no need to manually recalibrate or reconfigure.

If the controller ever needs replacement, all twelve configurations can easily be transferred to another instrument via the rear accessible Secure Memory Module (SMM).

Today, industrial processes utilizing feeders require a high degree of accuracy and must have a way to measure that accuracy. Feeder users have had to verify their performance by providing test material to a feeder manufacturer`s test facility where under laboratory conditions a “Two Sigma” test was performed. For your convenience, Hardy Instruments has added this Two Sigma Test feature to the HI 2160RCPlus. Your system’s performance can be verified at any time under your actual production conditions by an on demand, built-in Two Sigma test routine. This feature not only saves you money but also gives you near instant results.

The HI 2160RCPlus is a powerful building block when it comes to multiple feeder systems. It can act as a master to multiple controllers or as a slave to some other process input. Lock out the keypad and let multiple HI 2160RCPlus units be controlled from a common host computer or programmable controller.

Start your process and walk away with confidence, because the HI 2160RCPlus will watch and notify you of any problems. Display prompts and “alarm” relay outputs occur with conditions of rate tolerance errors and refill failures. Significant errors can cause a shutdown condition with specific control parameters. You decide at which levels to alarm or shutdown, and then let the HI 2160RCPlus do its job. Only authorized personnel can enter parameters, start the process and clear alarms. You assign one of three different security levels to each function. All personnel can view the data, but only those with the proper code can actually alter values.

Quick to set up and easy to use, the HI 2160RCPlus is designed for the realities of the workplace with a waterproof front panel, and tactile response keys. Frequently changed parameters are readily accessible and easy to view from the 80-character backlit display.

Hardy Instruments provides a wide variety of interface options, including standard bidirectional serial and optional Allen- Bradley Remote I/O, Profibus and Analog interfaces.
