As mentioned previously, the remote analog setpoint actions the measured value and the power feedback alternately, but every fourth cycle of MV, the remote analog setpoint is actioned instead.

For example, some eurotherj may provide excellent overshoot inhibition as an inherent characteristic, or perhaps superior response to setpoint changes. Take a look eugotherm our Returning an item help page for more details. Visit my eBay shop. Delivery time is estimated using our proprietary method which is based on the buyer’s proximity to the item location, the shipping service selected, the seller’s shipping history, and other factors. Add to basket. However, a wide PB low gain may result in control “wander” due to a lack of responsiveness of the controlled system.

If such a comparison of the MV and the setpoint reveals that the MV is greater, then the self-tuning mode does not proceed. The self-tuning controller as set forth in claim 36, wherein 80 control means returns said self-tuning controller to a predetermined control routine and causes said self-tuning controller to re-enter the self-tuning control mode at least subsequent to the determination of the error criteria and within a predetermined approach control parameter; said calculating means decreasing or increasing the PB value by a fixed amount, and determining if the count in said integral counter is greater than a second predetermined multiple; and said control means controlling the self-tuning controller in eurothrem adaptive mode control.

If the measured temperature error is corrected in a time less than approximately forty percent of an integral time, the control operation is considered to be underdamped and the PB is increased by one table setting. However, if the measured temperature error does not correct itself within approximately two integral times, the control operation is considered to be overdamped, and the PB is decreased by one table setting. What is claimed is: Learn More – opens in a new window or tab International postage and import charges paid to Pitney Bowes Inc.

This obtains a proper relationship between the Integral and Derivative eurotherrm constants. Periodically the eurothrm returns from the controller routines in step No. An outline of the procedure for the CLCM follows: Require no operator attention. Description Postage and payments. The introduction of microprocessors to control technology has greatly increased the flexibility of controllers as is known to the controller art.

Other control techniques include those used by ‘educated and sophisticated” system operators in which the control loops of a controlled system are tuned manually.

Report item – opens in a new window or tab. It is noted that PB is expressed as percent of instrument span, whereas TI and TD are eurotherk constants expresed in minutes.

This item will ship to United Statesbut the seller has not specified eurothegm options. Finally, if the system has not returned to the setpoint in the recovery window and the system response is determined to be as shown by curve c, then the system is judged to be underdamped and the PB is decreased as has been described previously.

The digital display is a fluorescent indicator panel FIP comprising a nine segment error bar display for analog indication of the proximity to setpoint, and four, seven-segment indicators providing accurate digital indication of process variables.

None Royal Mail International Signed. A method as set forth in claim 18 wherein euurotherm step of classifying the controller response as being underdamped includes determining if the count in said integral counter is less than a predetermined percentage of its previously stored value with error MV-SP being less than “1”; if error MV-SP is greater than “1” returning the self-tuning control to a predetermined routine for controlling said at least one load characteristic; and if the count in said integral counter is less than “1” classifying the controller response as being under-damped.

If self-tuning is enabled, then the power to the load is turned to “full-on” in step No.
