  • Page 5: Application

    1. APPLICATION The RE72 controller is destined for the temperature control in plastics, food, dehydration industries and everywhere when the temperature change stabilization is necessary. The measuring input is universal for resistance thermometers (RTD), ther- mocouple sensors (TC), or for linear standard signals.

    3. BASIC REQUIREMENTS, OPERATIONAL SAFETY In the safety service scope, the controller meets to requirements of the EN 61010-1 standard. Observations Concerning the Operational Safety: All operations concerning transport, installation, and commissioning  as well as maintenance, must be carried out by qualifi ed, skilled personnel, and national regulations for the prevention of accidents must be observed.

The main input is an universal input, to which one can connect different types of sensors or standard signals. The selection of the input signal type is made by the parameter iNty.

  • Page 31: Outputs

    7.4. Outputs The controller has maximal three outputs. Each of them can be confi gured as a control or an alarm output. For the proportional control (with the exception of analog outputs), the pulse period is additionally set. The pulse period is the time which goes by between succes- sive switches of the output during the proportional control.
  • Page 32: Control

    8. CONTROL 8.1. ON-OFF Control When a high accuracy of temperature control is not required, especially for objects with a great time constant and small delay, one can apply the on-off control with hysteresis. Advantages of this way of control are simplicity and liability, but disad- vantage are the occurring oscillations, even at small hysteresis values.
  • Page 33: Auto-Tuning

    8.2.1. Auto-tuning The controller has the function to select PID settings. These settings ensure in most of case an optimal control. To begin the auto-tuning, one must transit to the tune message (acc. to the fi g. 13) and hold down the push-button during at least 2 seconds.
  • Page 34 The auto-tuning process will be stopped without counting PID settings, if a supply decay occurs or the push-button is pressed. In this case, the control with current PID settings begins. If the auto-tuning is not achieved with success, the error code will be displayed acc.

    8.2.2. Auto-tuning and „Gain Scheduling” In case, when “Gain Scheduling” is used, one can carry out the auto-tuning in two ways.

    8.3. Step-by-step control The controller’s step-by-step control algorithm without feedback was changed. The description is provided below. The controller offers two algorithms of the step-by-step control for cylinder control: • with no feedback signal from the valve – opening and closing of the valve is based on PID parameters and control deviation, •...
  • Page 38 Fig. 18. Three-step step-by-step control with no feedback The principle of the algorithm shown in Fig.18 is based on conversion of changing the control signal to the relay opening / closing time referred to the full opening / closing time. The differences between the calculated and the actual valve position are unavoidable because of multiple changes in the direction of valve movement due to the inertia of a drive or its wear in the absence...
  • Page 39 In the specifi c case, the positioning is performed by completely closing the valve, it is carried out each time after: - turning the controller supply on - changing full open / close time. The time of full opening of the valve can have a different value than the time of closing.
  • Page 40: Gain Scheduling" Function

    8.4. „Gain Scheduling” function For control systems, Where the object behaves decidedly differen- tly in various temperatures, it is recommended to use the “Gain Schedu- ling” function. The controller allows to remember up to four sets of PID parameters and switch them over automatically. The switching between PID sets runs percussiveless and with hysteresis, in order to eliminate oscillations on switching limits.

    At set on-off control on the output 1 (parameter PB=0), one can set the control signal on 0% or 100% of the power, however when the PB parameter is higher than zero, one can set the control signal on any value from the range 0…100%. 12.3.

    The output signal is calculated acc. to the following formula. - out = out + (x - Ao.Lo) Ao.Lo - Ao.Hi The aOlo parameter can be set as higher than aOH, but the output signal will be then, inversed. 12.4. Set Point Change Rate – Soft Start The limitation of the temperature accretion rate is carried out through the gradually change of the set point value.
