  • Page 10: Introduction

    EZ-ZONE PM controllers offer options to reduce system complexity and the cost of control loop ownership. You can order the EZ-ZONE PM as a PID controller or an over-under limit controller, or you can combine both functions in the PM Integrated Controller. You now have the option to integrate a high-amperage power controller output, an over-under limit con- troller and a high-performance PID controller all in space saving, panel-mount packages.

  • Page 125: Changing Pm Integrated Model Number To Pm Express

    Changing PM Integrated Model Number to PM Express EZ-ZONE PM firmware revisions of 13 and above allow the user to switch between a PM Inte- grated control to a PM Express. Switching to a PM Express eliminates the complexity of the advanced PM Integrated control by allowing the user to operate with a simplified menu struc- ture.

  • Page 129: Autotuning With Tru-Tune

    Autotuning with TRU-TUNE+ ® The TRU-TUNE+ adaptive algorithm will optimize the controller's PID values to improve con- trol of dynamic processes. TRU-TUNE+ monitors the Process Value and adjusts the control pa- rameters automatically to keep your process at set point during set point and load changes. When the controller is in the adaptive control mode, it determines the appropriate output signal and, over time, adjusts control parameters to optimize responsiveness and stability.

  • Page 130: Inputs

    When autotuning is complete, the PID parameters should provide good control. As long as the loop is in the adaptive control mode, TRU-TUNE+ continuously tunes to provide the best pos- sible PID control for the process. ç WARNING! During autotuning, the controller sets the output to 100 percent and attempts to drive the Process Value toward the set point.

    You can create a scale range representing other units for special applications. You can re- verse scales from high values to low values for analog input signals that have a reversed ac- tion. For example, if 50 psi causes a 4 mA signal and 10 psi causes a 20 mA signal. Scale low and high low values do not have to match the bounds of the measurement range.

    The process temperature has to enter the normal operating range beyond the hysteresis zone to activate the alarm function. If the EZ-ZONE PM has an output that is functioning as a deviation alarm, the alarm is blocked when the set point is changed, until the process value re-enters the normal operating range.
