The procedures include selecting specific parameters, entering data and possible jumper position- ing.

  • Page 22: Configuration/Jumper Positioning

    Prior to first time operation of the instrument, the configuration procedures for the Program and Tune modes must be performed as applicable. Calibration and Test modes are not used as part of the instrument configuration or operation. These are used for service and mainte- nance functions and are discussed in Section 5.6 (page 59) of this manual.

    The instrument is provided with a time out feature. If the instrument is in any mode and no keypad activity takes place for 30 seconds, the instrument will time out and exit the mode automatically. The display will become the code for the respective mode. If a mode code is displayed for 5 seconds with no keypad activity, then the time out will cause the instrument to proceed to either the Control or Off mode, depending upon which operational state was in use before entry into the mode.

    Appendix B Glossary Assured Soak The instrument may be programmed to interupt the Profile Soak segment if the process value exceeds a selectable deviation from setpoint value. The Profile will restart from where it was stopped when the process value does not exceed the deviation value selected from setpoint. Automatic Reset (Integral) This parameter is used so that the instrument will compensate for process variable deviations from setpoint that occur when the process load characteristics change.
  • Page 74 Input Correction This parameter is adjustable from -300 to 300 units and is used as a method to compensate for a linear sensor error. Factory default is 0 = no correction. Display code iCi1 and iCi2. Manual Reset This parameter is adjustable from -1500 to 1500 units representing a manual shift of propor- tional band(s) relative to the normal position.
  • Page 75 Rate (Derivative) This parameter is adjustable from 0.0 to 10.0 minutes and specifies how the control action responds to the rate of change in the process variable. For example, if the process variable is rising rapidly to setpoint, power is turned off sooner than it would be if the rise were slow. In effect, derivative action anticipates lags within the system and shifts the proportioning band by an amount determined by the rate of change of the input sensor.
