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.
Chapter 1: Overview Introduction The Watlow® LEGACY™ SERIES panel mount controller is an industry leading PID controller that al- lows optimal performance utilizing simple control and menu functionality without complex features. It is ideally suited for basic applications and usage levels.
Overview 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 effectiveness in your application.
Overview Continued) Outputs The Output Wire Terminals are located on the Internal Functions back side of the controller. See Figure 3. The The controller will use input signals to calculate Outputs properly wired and configured can a value and then perform an operation. A sample perform various functions or actions in response of some functions may be as simple as: to information provided by a function such as,...

Input Events and Output Events Input events are internal state input event 2. The setting of Digital Input Function (Setup Page, Digital Input/Out- put 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.
Chapter 2: Install & Wiring INSTALLTION 1. For a PM3 Controller, make the panel cutout using the measurements shown on page 6. 2. For a PM6 Controller, make the panel cutout using the measurements shown on page 7. 3. Remove the green terminal connectors and the mounting collar assembly.

Filtering the signal may improve the performance of PID control in a noisy or very dynamic system. Unfiltered Input Signal Filtered Input Signal Time...
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.
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 numeri- cal display reflects the current installed firmware version). 2. Navigate to the Factory Page by simultaneously pushing and holding the Advance Key and the Re- set Key for approximately 8 seconds and then use the up or down arrow key to navigate to the Di- agnostic Menu.
