  • Page 5: Application

    1. APPLICATION The REC-ZK60 controller controls the temperature in objects through turning on and off the electrical controlling device according to the defined setting by the controller. It cooperates directly with RTD and TC. It is destined for the temperature control in telecommunication cabinets in food and drying industries and everywhere, where there is the necessity to stabilize the temperature changes.

    3. PREPARING THE CONTROLLER FOR OPERATION When unpacking the controller, please check whether the type and version code on the data plate correspond to the order. 3.1. Security The REC-ZK60 controller fulfils requirements concerning the security of electrical measuring automation instruments acc. to EN 61010-1 standard requirements concerning the resistance again- st electromagnetic noise acc.
  • Page 7 - Non-authorized removal of the required housing, inappropriate use, incorrect installation or operation create the risk of injury to personnel or damage to equipment. For more detailed information, please study the present user’s manual. - 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.
  • Page 8 - The electrical installation must be carried out according to the appropriate regulations (cable cross-sections, fuses, PE connection). Additional information can be obtained from the user’s manual. - The documentation contains information about installation in compliance with EMC (shielding, grounding, filters and cables). These notes must be observed for all CE-marked products.

    3.4. Installation recommendations In order to obtain a full fastness against electromagnetic noise in an environment with unknown noise level, it is recommended to observe following principles: - do not supply the controller from the network, in the proximity of devices generating high pulse noise and do not apply common earthing circuits, - apply network filters, - apply metallic shields in the shape of tubes or braids to conduct...

    6. CONTROL 6.1. On-Off control When a high precision of the temperature control is not required, especially for objects with a high time-constant and a small delay, one can apply the on-off control with hysteresis. Advantages of this control way are the simplicity and reliability, however its defect is the oscillation formation, even at small hysteresis values.

  • Page 20: Pid Control

    6.2. PID control When we want to obtain a better accuracy of the temperature control, one must apply the PID algorythm. The controller tuning to the object consists on setting the value of the proportional element, integrating and differentiating elements, and the output pulse repetition period. The impulse period is the time which goes by between successive switchings of the output during the proportional control.
  • Page 21 6.2.2. Selection of PID settings by the object identification method Set the on-off control with the minimal hysteresis. Set the set point on the normal work level (or on a lower level if overshoots could be cause damages) and on normal load conditions. Fig.8.
  • Page 22 6.2.3. Correction of PID settings The best is to choose parameters changing the value into a twice higher or twice lower. During the change, one must refer to following principles: a) Slow jump response: - decrease the proportional band, - decrease the integration and the differentiation time. b) Overshoots: - increase the proportional band, - increase the differentiation time.
