Starting from the dashed lines, the dispersion of energy takes place symmetrically to the left and right (see arrows). For as long as the total output level of the two devices is below 100 %, two device currents in a single phase are prevented from overlapping.

    6 Special device functions 6.5 Subordinate control loop Subordinate control loops are used to eliminate or compensate for external disturbances, such as mains voltage fluctuations and changes in load resis- tance, that would have a negative effect on the control process. 6.5.1 Closed control loop without subordinate control Supply voltage...

  • Page 82: Closed Control Loop With Subordinate Control

    6 Special device functions Disadvantage: A continuing constant temperature is no longer assured. The power controller recognizes the deviation through the relatively slow re- sponse of the temperature control loop and increases its output level (y ) until the furnace reaches the original temperature (250 °C) again. 6.5.2 Closed control loop with subordinate control To avoid power variations caused by mains voltage fluctuations, a subordi- nate control loop is built into the power controllers.

  • Page 84 6 Special device functions es towards the setpoint value, the power fed to the furnace is reduced (at the same load voltage level). This means that the power controller alone is able to slow the approach to the setpoint value. This damps out any tendency to over- shoot the final temperature.
  • Page 85 6 Special device functions Figure 3: Heating element with a negative TC Looking at the power equation P = I · R, we can see that an I control has the same regulatory effect on the power as already described for the U control.

    6 Special device functions 6.6 Resistance limitation (r-control) This is only possible in power controllers with current and voltage measurement that are fitted with subordinate control P (Code 001 in the order code) and only functions for load resistors with a posi- tive temperature coefficient.

    6 Special device functions 6.7 Current limiting Current limiting is only possible for power controllers with load current measurement; in other words, subordinate control I,I (code 010 in the order code), or P (code 001 in the order code) must be selected in the order details.

    6 Special device functions 6.11 Thyristor control logic (switch) Operating mode If the power controller is set to Thyristor control Logic (switch), the power controller operates as an electronic switch. For as long as the configured digital or analog input is closed, the thyristors are fired in zero crossing of the mains voltage and are only locked again when the digital or analog input is opened.
