  • Page 9: 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 Limit, PID or an Integrated PID/Limit con- troller. You can also select from a number of industrial serial communications protocols as options to enable connectivity into a distributed control system or to simply help manage sys- tem performance over a network.

  • Page 10: A Conceptual View Of The Pm

    A Conceptual View of the PM The flexibility of the PM software and hardware allows for a large range of configurations. Ac- quiring a better understanding of the controller’s overall functionality and capabilities while at the same time planning out how the controller can be used will deliver maximum effective- ness in your application.

  • Page 11: Outputs

    Keep in mind that a function is a user-programmed internal process that does not execute any action outside of the controller. To have any effect outside of the controller, an output must be configured to respond to a function. Outputs Outputs can perform various functions or actions in response to information provided by a function such as, removal of the control voltage to a contactor;...

  • Page 96: 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.

Click on the link that follows to acquire the latest version of the PM PID Express User’s Guide. http://www.watlow.com/en/Resources-And-Support/Technical-Li- brary/User-Manuals Once there, simply enter express in the “Keyword” field to find the appropriate docu- ment.

  • Page 99: Calibration

    Calibration Before performing any calibration procedure, verify that the displayed readings are not within published specifications by inputting a known value from a precision source to the analog in- put. Next, subtract the dis- played value with the known value and compare this differ- ence to the published accuracy Negative Calibration Offset will compensate for the difference...

  • Page 101: Filter Time Constant

    Filter Time Constant Filtering smooths an input signal by applying a first-order filter time constant to the signal. Fil- tering the displayed value makes it easier to monitor. Filtering the signal may improve the performance of PID control in a noisy or very dynamic system. Unfiltered Input Signal Filtered Input Signal Time...

  • Page 102: Range High And Range Low

    Range High and Range Low With a process input, you must choose a value to represent the low and high ends of the current or voltage range. Choosing these values allows the controller’s display to be scaled into the actual working units of measurement. For example, the analog input from a humid- ity transmitter could represent 0 to 100 percent relative humidity as a process signal of 4 to 20mA.

    To check the firmware revision of your control do one of the following: 1. Cycle power to the control while observing the number in the top display (this momentary numerical display reflects the current installed firmware version). 2.

  • Page 104: Hysteresis

    Hysteresis An alarm state is triggered when the process value reaches the high or low set point. Hystere- sis defines how far the process must return into the normal operating range before the alarm can be cleared. Hysteresis is a zone inside each alarm set point. This zone is defined by adding the hysteresis value to the low set point or subtracting the hysteresis value from the high set point.

  • Page 105: Blocking

    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.
