    GMC-I Messtechnik GmbH R2700–22 Conversion of Parameter Sets If the binary input is configured to parameter set conversion (SEt2 / SEt3), parameter set 2/3 is loaded when the contact is closed, and paramter set 1 is loaded when the contact is open. The active configuration is overwritten in each case. The W2 LED lights up when parameter set 2 and/or 3 is active.

  • Page 23: Configuring The Switching Outputs And The Continuous Output

    If, in the case of device variant A1 or A4, two relay outputs are required for the actuating signals, for example in the case of three-step or step-action control, the alarm outputs can be exchanged with the actuator outputs. The Out = XCh configuration (see page 16) exchanges the functions of out1 with A1 and out2 with A2. GMC-I Messtechnik GmbH R2700–23...

  • Page 24: Actuator Output For Contactor

    GMC-I Messtechnik GmbH R2700–24 Actuator Output for Contactor If, during ascertainment of control parameters (manual optimization or self-tuning), a cycle time results which is significantly shorter than advisable for the service life of the contactor, cycle time can be increased to the limit of system controllability by configuring the actuating outputs for contactor control (rELA = YES).

    The targeted setpoint is displayed (not the currently valid setpoint) with an r at the left-hand digit. Limit values Relative limit values make reference to the ramp, not the targeted setpoint. As a rule, no alarm is triggered for this reason. GMC-I Messtechnik GmbH R2700–25...

  • Page 26: Adaptive Measured Value Correction

    GMC-I Messtechnik GmbH R2700–26 Adaptive Measured Value Correction If a control loop is interfered with by periodic disturbance of the actual value, control can be improved by activating adaptive measured value correction. Periodic disturbance is thus suppressed, without impairing the controller’s ability to react to system deviations. Correction is adapted to the oscillation amplitude of the disturbance to this end, and only the mean value is forwarded to the controller.

  • Page 27: Suppression Of Periodic Disturbances

    Periods can be selected within a range of 0.3 to 25 seconds, and the filter remains inactive for other setting values. Due to the fact that this suppression filter influences control dynamics, ascertainment of control parameters by means of self-tuning or manual optimization has to be performed while oscillation suppression is active.

  • Page 28: Hot-Runner Control

    GMC-I Messtechnik GmbH R2700–28 Hot-Runner Control By configuring the switching output for heating as a hot runner (Outx = Hotr), the manipulated variable is read out as a rapidly pulsating signal, i.e. actuation cycle time is 0.1 seconds regardless of the actuation cycle time parameter setting.

  • Page 29: Feed-Forward Control

    Example: If a machine requires an average of 70% heating power during production operation, but only 10% during idle time, the difference of Y FF is set to 60%, and the binary input is only activated during production. GMC-I Messtechnik GmbH R2700–29...

  • Page 38: Manual Optimization

    GMC-I Messtechnik GmbH R2700–38 Manual Optimization Parameters Pb I, Pb II, tu and tc are determined by means of manual optimization in order to maintain optimized controller dynamics. A start-up test or an oscillation test is performed to this end.
  • Page 39 Step-action controller If manipulating factor limiting was active, the proportional band must be corrected: Y H positive: Pb I multiply by 100% / Y H Y H negative: Pb II multiply by -100% / Y H GMC-I Messtechnik GmbH R2700–39...
  • Page 40 GMC-I Messtechnik GmbH R2700–40 Performing the Oscillation Test If a start-up test is not possible, for example if neighboring control loops influence the actual value too greatly, if the switching output for cooling must be active in order to maintain the actual value (cooling operating point), or if optimization is required directly to the setpoint for any given reason, control parame- ters can be determined by means of sustained oscillation.
  • Page 41 – For 3-step, split range and step-action controllers, the dead band can be increased from dbnd = 0, if control of the switching outputs (or continuous output) changes too rapidly, for example due to an unsteady actual value. GMC-I Messtechnik GmbH R2700–41...

  • Page 42: Self-Tuning

    GMC-I Messtechnik GmbH R2700–42 Self-Tuning Self-tuning is used to optimize controller dynamics, i.e. the Pb I, Pb II, tu and tc parameters are set. Preparation – Complete configuration must be performed before self-tuning is started. Current Start – The setpoint value is adjusted to the value which is required after self-tuning.

    8x4x may also be 9x4x, Ax4x, bx4x. • When configured as a step-action controller (R2600, features A2, A4), the configuration of the corresponding output is not Outx = CooL in the case of the R2700, but rather Outx = HcLo.
  • Page 53 Converting Parameters In the case of the R2700, the proportional bands are specified in the unit of measure of the controlled variable, instead of as a percentage of the measuring range span as is the case with the R2600. Conversion is accomplished as follows: Pb (R2700) = Pb (R2600) x MRS (R2600) / 100%.
