Safety Information We use note, caution and warning symbols throughout this book to draw your attention to important operational and safety information. A “NOTE” marks a short message to alert you to an important detail. A “CAUTION” safety alert appears with information that is important for protecting your equipment and performance. Be especially careful to read and follow all cautions that apply to your application.
Warranty The EZ-ZONE® PM is manufactured by ISO 9001-registered processes and is backed by a three-year warranty to the first purchaser for use, providing that the units have not been misapplied. Since Watlow has no control over their use, and sometimes misuse, we cannot guarantee against failure. Watlow’s obligations hereunder, at Watlow’s option, are limited to replacement, repair or refund of purchase price, and parts which upon examination prove to be defective within the warranty period specified.

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 control-loop ownership. You can also select from a number of serial communications options to help you manage system performance over a network. It just got a whole lot easier to solve the thermal requirements of your system. Because the EZ-ZONE PM controllers are highly scalable, you only pay for what you need.
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 EZ-ZONE ® family controller’s and their 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.
Input Events and Output Events Input events are internal states that are set by the digital inputs. Digital Input 5 provides the state of input event 1, and Digital Input 6 provides the state of input event 2. The setting of Digital Input Function (Setup Page, Digital Input/Output Menu) does not change the relationship between the input and the event. An input will still control the input event state, even if Digital Input Function is set to None.

Communication Protocols When using a communications protocol in conjunction with the EZ-ZONE PML there may be two possible ports (instances) used. Port 1 or instance 1 is always dedicated to Standard Bus communications. This same instance can also be used for Modbus RTU if ordered. Depending on the controller part number port 2 (instance 2) can be used with Modbus, CIP and Profibus. For further information read through the remainder of this section.
Profibus DP To accommodate for Profibus DP addressing the following menus contain a column identified as Profibus Index. Data types used in conjunction with Profibus DP can be found in the table below. Data Types Used with Profibus real = Float, IEEE 754 32-bit int = Signed 16-bit integer byte = 8-bits To learn more about the Profibus DP protocol point your browser to http://www.profibus.org.

Changing PM Limit Model Number to PM Express Limit EZ-ZONE PM Limit firmware revisions of 13 and above allow the user to switch between a PM Limit control to a PM Express Limit. Switching to a PM Express Limit eliminates the complexity of the PM Limit control by allowing the user to operate with a simplified menu structure. Note: When switching from a Limit control to an Express version, optional PM hardware (even though installed) and firmware features not available in a PM Express will no longer work.
How to Restore Original PM Model Number 1. Enter Factory Page [FCty ] , Calibration Menu [`CAL] via front panel or using EZ-ZONE Configurator Software. 2. Once there, using the green advance button navigate to the Part Number [``Pn] prompt (lower display). The upper display will show User [User] indicating the control is currently a PM Express. 3. Push the green advance button one more time where the Public Key [Cod e] prompt will be displayed in the lower display and the number [4999] in the upper display.
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 input. Next, subtract the displayed value with the known value and compare this difference to the published accuracy range specification for that type of input.
10. Read Electrical Measurement value [`Mu] of controller via EZ-Configurator or RUI. This will be referred to as Electrical Measured High. Record high value ______________ 11. Calculated Electrical Input Slope = (Precision High – Precision Low) / (Electrical Measured High - Electrical Measured Low). Calculated Slope value ___________ 12. Calculated Electrical Input Offset = Precision Low – (Electrical Input Slope * Measured Low). Calculated Offset value ___________ 13.
Scale High and Scale Low When an analog input is selected as process voltage or process current input, you must choose the value of voltage or current to be the low and high ends. For example, when using a 4 to 20 mA input, the scale low value would be 4.00 mA and the scale high value would be 20.00 mA. Commonly used scale ranges are: 0 to 20 mA, 4 to 20 mA, 0 to 5V, 1 to 5V and 0 to 10V. You can create a scale range representing other units for special applications.
Resetting a Tripped Limit Output 2 will always be a Form A (normally open) Mechanical Relay and it will always be internally tied to the limit function. When the limit is in a safe state the internal coil for this relay will be energized, therefore the relay will be closed. When a condition occurs that causes the limit to trip, the internal coil will deengerize causing the relay to latch open.
Alarm Hysteresis High Side Alarm Range Alarm High Set Point Alarm Hysteresis Temperature An alarm state is triggered when the process value reaches the alarm high or alarm low set point. Alarm hysteresis defines how far the process must return into the normal operating range before the alarm can be cleared. Alarm hysteresis is a zone inside each alarm set point.
Using Lockout and Password Security If unintentional changes to parameter settings might raise safety concerns or lead to downtime, you can use the lockout feature to make them more secure. There are two methods of lockout that can be deployed, both of which are accessible from the Factory Page. Method 1- Change the value of the Read Lock [rloc] (1 to 5) and Set Lock [sloc] (0 to 5) prompts where the higher the value or setting for each translates to a higher security clearance (greater access).
** Diagnostic Menu and all associated prompts are always visible and never writable.
Note: a. If the the Rolling Password is off push the Ad-vance key one more time where the Password [pass] prompt will be displayed. Proceed to either step 7a or 8a. Pushing the Up ¿ or Down ¯ arrow keys enter either the User or Administrator Password. Once entered, push and hold the Reset key for two seconds to return to the Home Page. b. If the Rolling Password [roll] was turned on proceed on through steps 3 - 9. RESET 3.
CIP - Communications Capabilities With the introduction of CIP a user can now collect data, configure a device and control industrial devices. CIP is an open protocol at the application layer fully managed by the Open DeviceNet Vendors Association (ODVA, http://www.odva.org). Being that this is an open protocol there are many independent vendors offering a wide array of devices to the end user.
Compact Assembly Class Along with the standard implicit assembly where each module parameter (member) occupies one 32-bit assembly location there is also a Compact Class assembly. The need for the Compact Class assembly members became apparent as the number of member instances grew with the EZ-ZONE family of controls.
Software Configuration Using EZ-ZONE® Configurator Software To enable a user to configure the PML (Limit) 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.
After clicking on the "Next" button, the software will scan the network for the zone addresses specified while showing the progress made (as shown in the graphic below. When complete the software will display all of the available devices found on the network as shown below Available Network Devices Displayed Searching Network for Devices The PM9L is shown highlighted to bring greater clarity to the control in focus.
Navigating from one menu to the next is easy and clearly visible. Simply slide the scroll bar up or down to display the menu and parameter of choice. If there is a need to bring greater focus and clarity to the parameters of interest simply click on the negative symbol next to any of the Menu items. As an example if it is desired to work within the Operations page click the negative sign next to Setup where the Setup Page will then collapse.
