The MV is compared with setpoint surotherm and if MV is less than one-half setpoint, the self-tuning procedure is resumed at step nine as described above. Click for automatic bibliography generation. A determination is then made as to whether the number stored in the Integral counter is greater than 4 times its previously stored value.

There are several established and well known techniques for evaluating and determining the control characteristics and parameters of controlled loops and systems and which are adaptable to the design of self-tuning controllers. It is again noted that the goal in the above Ziegler-Nichols techniques and the Cohen-Coon techniques is to obtain a 4: Contact the seller – opens in a new window or tab and request a shipping method to your location.

LEDS on the front panel provide indication of alarms one and two, outputs one and two and a remote operation. A significant feature of the controller is the employment of charge storage characteristics to retain specific information in the event of loss of power, commonly referred to as a non-volatile memory.

Redeem eurothfrm points Conditions for uk nectar points – opens in a new window or tab. The self-tuning controller as set forth in claim 28, wherein said monitoring means monitors the control response to perturbations, and said calculating means changes the PB setting if said at least one load characteristic does not reach setpoint within a particular time frame with respect to the time counted by said integral time counter with the controler demanding a particular type of control power at the eurohherm of a perturbation.

Mount Pleasant, Michigan, United States. This amount is subject to change until you make payment. Mouse over to Zoom – Click to enlarge. A straight line drawn tangent to the process reaction curve at the point of inflection has a slope R as shown in FIG. If not, the self-tuning mode is not entered. Euroherm junction compensation is provided by a sensor housed within a thermocouple input block. The setpoint is obtained from memory location FCO.

This item will post to United Statesbut the seller hasn’t specified postage options. If the rate of rise of the MV has not so decreased then the program returns to the controller routines in step No. Estimated on or before Wed. 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.

Thermocouple cold junction compensation is provided by a custom thick film circuit not shown. People eurotberm viewed this item also viewed. Eurotherm Corporation Reston, VA. Alternatively, if the Integral term is set to a fast value, the heater power level could be shifted too quickly, thereby inducing oscillation as the controller is attempting to control faster than the load can change.

Additionally, because the ITC counter is started when the power to the load is first switched off, the ITC eyrotherm reflects the normal thermal inertia of the system. These are some of the factors that may make one controller more suitable than another for a particular system to be controlled.

The two alarm channels can be used in any configuration. None of the specific initialization operations are of significance to the present invention as such procedures are primarily concerned with the circuitry of the controller utilized in conjunction with the self-tuning portion of the inventive method and apparatus, in this instance the controller.

The MV eurofherm monitored until it drops to the stored power turn ON point and when it does, “two” is added to the MV and the resultant value stored as the power cut-off point.

An untrained operator of the self-tuning controller can operate it with minimum effort or involvement in the control process. The self-tuning controller as set forth in uerotherm 37, wherein said calculating means determines if the count in said integral time counter is less than a predetermined percentage of the previously stored value, with error MV-SP being less than “1” and controller response classified as underdamped; said control means returning the self-tuning controller to a predetermined routine for controlling said at least one load characteristic with error MV-SP greater than “1”; and said classifying means classifying the controller response as being underdamped with the count in said integral counter less than eurothermm.

Add to watch list. However, if the up Detect Scroll Button has been actuated, then the self-tuning algorithm proceeds to step No. Add to Watch list Watching. Watch list is full.
