1 Chapter 1: Overview The EZ-ZONE ® PM takes the pain out of solving your thermal loop requirements. Watlow’s EZ-ZONE PM controllers offer options to reduce system complexity and the cost of controlloop 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 Limit Controller.
A Conceptual View of the PM The flexibility of the PM’s software and hardware allows a large range of configurations. Acquiring 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 effectiveness in your application. It is useful to think of the controller in three parts: inputs; procedures; and outputs.
Getting Started Quickly the default value of 75 °F to the desired value. As the Set Point increases above the Process Value, output 1 will come on and it will now begin driving your output device. The PV function as shown in the graphic below is only available with PM4/8/9 models. The PM control has a page and menu structure that is listed below along with a brief description of its purpose. Setup Page Push and hold the up and down keys (¿ ¯) for 6 seconds to enter.

Installation Don't be afraid to apply enough pressure to properly install the controller. The seal system is compressed more by mating the mounting collar tighter to the front panel (see pictures above). If you can move the case assembly back and forth in the cutout, you do not have a proper seal. The tabs on each side of the mounting collar have teeth that latch into the ridges on the sides of the controller.
Returning the Controller to its Case 1. Ensure that the orientation of the controller is correct and slide it back into the housing. Note: The controller is keyed so if it feels that it will not slide back in do not force it. Check the orientation again and reinsert after correcting. 2. Using your thumbs push on either side of the controller until both latches click. Chemical Compatibility This product is compatible with acids, weak alkalis, alcohols, gamma radiation and ultraviolet radiation.

See model number information in the Appendix for more information. If there is only one instance of a menu, no submenus will appear. How to Start a Profile The Profiling Page allows you to enter your ramp and soak profile information. After defining the profile follow the steps below to run the profile: 1.

Saving and Restoring User Settings Recording setup and operations parameter settings for future reference is very important. If you unintentionally change these, you will need to program the correct settings back into the controller to return the equipment to operational condition. After you program the controller and verify proper operation, use User Save Set [USr;S] (Setup Page, Global Menu) to save the settings into either of two files in a special section of memory.
Manual Tuning In some applications, the autotune process may not provide PID parameters for the process characteristics you desire. If that is the case, you may want to tune the controller manually. 1. Apply power to the controller and establish a set point typically used in your process. 2. Go to the Operations Page, Loop Menu, and set Heat Proportional Band [`h;Pb] and/or Cool Proportional Band [`C;Pb] to 5. Set Time Integral [``ti] to 0. Set Time Derivative [``td] to 0. 3.
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 possible PID control for the process. ç WARNING! During autotuning, the controller sets the output to 100 percent and attempts to drive the process variable toward the set point. Enter a set point and heat and cool power limits that are within the safe operating limits of your system.
Filter Time Constant Scale High and Scale Low Filtering smoothes an input signal by applying a first-order filter time constant to the signal. Filtering 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. Adjust the filter time interval with Filter Time [`FiL] (Setup Page, Analog Input Menu). Example: With a filter value of 0.
NO-ARC Relay A NO-ARC relay provides a significant improvement in the life of the output relay over conventional relays. Conventional mechanical relays have an expected life of 100,000 cycles at the rated full-load current. The shorter life for conventional relays is due to the fact that when contacts open while current is flowing metal degradation occurs. This action produces unavoidable electrical arcing causing metal to transfer from one contact to the other.
is present, the controller will perform closed-loop control. Closed-loop control uses a process sensor to determine the difference between the process value and the set point. Then the controller applies power to a control output load to reduce that difference. If a valid input signal is not present, the controller will indicate an input error message in the upper display and [Attn] in the lower display and respond to the failure according to the setting of Input Error Failure [FAiL].
[MAn] for manual mode. Use the Up ¿ or Down ¯ keys to select [AUto]. The automatic set point value will be recalled from the last automatic operation. Changes take effect after three seconds or immediately upon pressing either the Advance Key ‰ or the Infinity Key ˆ. On-Off Control On-off control switches the output either full on or full off, depending on the input, set point and hysteresis values.
Proportional plus Integral plus Derivative (PID) Control Use derivative (rate) control to minimize the overshoot in a PI-controlled system. Derivative (rate) adjusts the output based on the rate of change in the temperature or process value. Too much derivative (rate) will make the system sluggish. Derivative action is active only when the process value is within twice the proportional value from the set point. Adjust the derivative with Time Derivative [``td] (Operations Page, Loop Menu).
fect of analog, phase-angle fired control. Select the AC Line Frequency [AC;LF] (Setup Page, Global Menu), 50 or 60 Hz.
View or change alarm set points with Low Set Point [`A;Lo] and High Set Point [`A;hi] (Operations Page, Alarm Menu).
100%. Once there, the control will then begin to monitor the Open Loop Detect Deviation [`l; d d ] as it relates to the value entered for the Open Loop Detect Time [`l; d t] . If the specified time period expires and the deviation does not occur, an Open Loop Error will be triggered. Once the Open Loop Error condition exists the control mode will go off. Note: All prompts identified in this section can be found in the Loop Menu of the Setup Page.

4. Execute the calculation defined below (7b or 8b) for either the User or Administrator. 5. Enter the result of the calculation in the upper display by using the Up ¿ or Down ¯ arrow keys or use EZ-ZONE Confgurator Software. 6.

Software Configuration Using EZ-ZONE® Configurator Software To enable a user to configure the PM control using a personal computer (PC), Watlow has provided free software for your use. If you have not yet obtained a copy of this software insert the CD (Controller Support Tools) into your CD drive and install the software.
In the previous screen shot the PM is shown highlighted to bring greater clarity to the control in focus. Any EZ-ZONE device on the network will appear in this window and would be available for the purpose of configurationor monitoring. After clicking on the control of choice simply click the next button once again. The next screen appears below. more clarity for the area of focus by not displaying unwanted menus ad parameters.
Lastly, when the configuration is complete click the "Finish" button at the bottom right of the previous screen shot. The screen that follows this action can be seen below. The user can save the file to any folder of choice. Although the PM control now contains the configuration (because the previous discussion focused on doing the configuration on-line) it is suggested that after the configuration process is completed that the user save this file on the PC for future use.
