  • Page 5: Application

    1. APPLICATION The RE71 controller is destined for the temperature control in plastics, food, dehydration industries and everywhere when the temperature sta- bilizing is necessary. Main features of the RE71 controller: direct co-operation with resistance thermometers (RTD) or thermo- couple (TC) sensors, two-stage control acc.

    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 qualified, skilled personnel, and national regulations for the prevention of accidents must be observed.

Before the insertion into the panel, one must check the correct placement of the seal. After the insertion into the hole, fix the controller by means of screw clamps.

    4.2. Electrical Connections Make electrical connections to terminal strip and next, insert strips into the controller sockets. The controller has two separable terminal strips. One strip enables the connection of the supply and outputs by a wire of 2.5 mm cross- section, the second strip enables input signal connections by a wire of 1.5 mm...

    6.1. Programming Controller Parameters The pressure and holding down the button during ca 2 seconds causes the entry in the programming matrix. The programming matrix can be protected by an access code. In case when giving a wrong value of the code, it is only possible to see settings through – without possibility of changes.

    6.3. Setting Change The change of parameter setting begins after pressing the but- ton during the display of the parameter name. The setting choice is carried out through buttons, and accepted by the button. The change cancellation follows after the simultaneous pressure of buttons or automatically after 30 sec since the last push pressure.

  • Page 18: Innovative Smart Pid Algorithm

    7.2. PID Control When we want to obtain a higher accuracy of temperature control, one must use the PID algorithm. The applied innovative SMART PID algorithm is characterized by an increased accuracy for the expanded range of control object classes. The fine tuning of the controller to the object consists on the settlement of the proportional element, integration element, differentiation element and output pulsing period.
  • Page 19 The autotuning process will be broken without PID settings calculations, if a controller supply decay occurs or the button is pressed. In such a case, the control with current PID settings will begin. If the autotuning experiment does not end with success, then an error code will be displayed acc.

    9.2. Manual Control The manual control gives the possibility to identify, test the object, or control it after a sensor damage. The entry to the manual control mode follows after holding the button down during the control signal display. The manual control is signalled by the pulsation of the diode with .
