Such manual tuning techniques involve observing the response of the system under certain conditions and calculating the control parameters from a set of formulas, which are typically fairly simple.
The recovery window of the self-tuning technique is established between 0. If the system response is not within desired limits, the PB is recalculated to optimize the system response characteristics.
If the comparison in step No. Most conventional temperature controllers, whether analog or microprocessor-based, are three-term, PID controllers. With the use of a microprocessor such a control parameter is now adjustable.
Each alarm drives a changeover relay and indication is via front panel LEDS. Have one to sell?
The watchdog circuitry provides a reset for the microprocessor should a fault occur and ensures that the microprocessor is placed in the correct state of eeurotherm on start-up. Resume making your offer if the page doesn’t update immediately. Image not available Photos not available for this variation.
The method as set forth in any one of claims 44, 45, 46 or 47, wherein said period of oscillation is one-quarter cycle, said selected point is substantially one-half way between setpoint, said reference condition is ambient temperature, and said predetermined power level is zero.
This control module was included in a plant acquisition. For additional information, see the Global Shipping Programme terms and conditions – opens in a new window or tab.

Watch list is full. The setpoint is divided by two. Such re-tuning often is very difficult and requires considerable knowledge and skill of the process operator. A primary object of the invention is to provide self-tuning controllers having some or all of the following capabilities:. A method of self-tuning as set forth in claim 12 further comprising determining if the MV has reached said power cut-off point; removing power from said load with said MV at said power cut-off point, and returning the start-up procedure to said predetermined routine with said MV less than said power cut-off point; and with said power removed from said load, recording the rate of rise of MV; and returning said start-up procedure to said predetermined routine.
The self-tuning controller as set eurothem in claim 33, wherein said means for controlling returning the self-tuning controller to a predetermined control routine; and re-entering the self-tuning programmed control at least subsequent to any one of the incrementation of said integral counter, storing X minthe storing of X maxsaid controlling means controlling said self-tuning controller in a normal three term control mode, and the enablement of said adaptive control mode.
Our wide range of products is rich in features and designed for easy operation and reduced engineering time. The program returns to wurotherm self-tuning algorithm in step No.
This item may be a floor model or store return that has been used. 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 wurotherm actioned instead.
