  • Page 85: Control Basics

    6.4.1 Control basics Definition A brief explanation of terms Actuating - Initial value of the controller to compensate for the differ- signal ence between the actual value and target value (control deviation). PID con- - The PID controller operates with extreme speed and preci- troller sion and consists of a P, I and D-component.
  • Page 86 If the temperature range of an application is -20 to 80 °C, for example, a control setting of -10 to 20 °C is most suitable. Influence of control parameters on the control action Fig. 48: Ideal setting If the Xp parameter selected is too large, the actual value will reach the proportional range early and the P-component will be less than 100 % of the actuating signal.

  • Page 87: Overview Of Internal Control Parameters

    In the case shown here, the preset I component is too large (parameter Tn too small, Tn must be increased). The I-component integrates the control deviation until it becomes 0. If integration proceeds too rapidly, the actuating signal, i.e. the output signal of the controller, is too large. As a result, the actual value fluctuates (fading) around the target value.

  • Page 88: Overview Of External Control Parameters

    6.4.3 Overview of external control parameters External control consists of a master controller (external controller) and a slave controller (internal controller). The temperature of the consumer to be temperature controlled is also required. In general this is deter- mined with an external “Pt100 sensor”. The master controller compares the set temperature with the external temperature (consumer temperature) and, from these temperatures, calculates the set temperature (set_internal) for the slave controller...

    Automatic heat limit for smaller pump In the Integral XT the heat output is increasingly reduced if the pump power power falls below 150 W (pump level < 4). This measure protects the heat transfer liquid from overheating on the heater surface and thus prevents premature aging of the heat transfer liquid.

  • Page 94: Cooling

    With the dynamic heat limiter, you limit the heating output of the device. At low flow rates at the heaters, there is a risk that the heat transfer liquid will overheat locally. This can lead to premature aging, oil cracking with silicone oils (depolymerization) or boiling.
