Overview

A Conceptual View of the PM

  • The flexibility of the PM software and hardware allows for 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 terms of functions; there are internal and external func-tions. An input and an output would be consid-ered external functions where the limit, PID or alarm function would be an internal function. Information flows from an input function to an internal function to an output function when the controller is properly configured.
  • A single PM controller can carry out several functions at the same time, for instance (but not limited to), checking for a limit condition, monitoring for several different alarm situations, etc…
  • To ensure that the application requirements are being met, it is important to first give thought to each external process and then configuring the controller’s internal functions to properly accommodate the application requirements.

Figure 1: PM6 Controller Shown Here
A PM with digital input/output (DIO) hardware includes two sets of terminals where each of which can be used as either an input or an out-put. Each pair of terminals must be configured to function as either an input or output with the direction parameter in the Digital Input/Output Menu (Setup Page). Each digital input reads whether a device is active or inactive.
The Reset Key on the front panel of the PM also operates as a digital input by toggling the function assigned to it in the Digital Input Function parameter in the Reset Key Menu
(Set-up Page).

Inputs

  • The inputs terminal connections are located on the back side of the controller. See Figure 2. The controller, properly wired and configured will provide the information that any given programmed procedure can act upon. In a simple form, this information may come from an operator pushing a button or from a sensor monitoring the temperature of a part being heated or cooled.
  • Each analog input typically uses a thermocouple or RTD to read the process temperature. It can also read volts, current or resistance, allowing it to use various devices to read a wide array of values. The settings in the Analog Input Menu (Setup Page) for each analog input must be configured to match the device connected to that input.

Internal Functions

The controller will use input signals to calculate a value and then perform an operation. A sample of some functions may be as simple as:

  • Detect a failure of the primary sensing device and trip a contactor to remove power from the heating element.
  • Reading a digital input to set a state to true or false.
  • Evaluate an incoming temperature to determine an alarm state (on or off).
  • Compare an input value to the set point and calculate the optimal power for a heater.

To set up a function, it’s important to define the source, or instance, to use. For example, if the control is equipped with DIO it can be configured to respond to an alarm. If configured as such, the digital output must be tied to the desired alarm instance (1 to 4). Using this as an example, the Function for the digital output would be defined as an Alarm where the Instance would be selected as 1, 2, 3, or 4 corresponding to the alarm instance that will drive the output.
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

The Output Wire Terminals are located on the back side of the controller. See Figure 3. The Outputs properly wired and configured can perform various functions or actions in response to information provided by a function such as, removal of the control voltage to a contactor; operating a heater, turning a light on or off, unlocking a door, etc. Assign a Function to any available output on the Setup Page within the Output Menu or Digital Input/Output Menu. Then select which instance of that function will drive the selected output. For example, you might assign an output to respond to alarm 4 (instance 4). You can assign more than one output to respond to a single instance of a function. For example, alarm 2 could be used to trigger a light connected to output 1 and a siren con-nected to digital output 5.

Installation

  1. For a PM3 Controller, make the panel cutout using the measurements shown on page 9.
  2. For a PM6 Controller, make the panel cutout using the measurements shown on page 10.
  3. Remove the green terminal connectors and the mounting collar assembly.WATLOW-PM3-PM6-LEGACYTM-Express-Limit-Controller-IMG- \(7\)
  4. Insert the controller into the panel cutout from the front. See Figure 2. The controller shown is a PM6 Controller.
  5. Orient the collar base so the flat side faces the front and the screw openings are on the sides (see Figure 2), then slide the base over the back of the controller..
  6. Slide the mounting bracket over the controller with the screws aligned to the collar base. See Figure 2. Push the bracket gently but firmly until the hooks snap into the slots in the case.
  7. Tighten the two #6-19 x 1.5 in. screws with a Phillips screwdriver until the device is flush to the panel (3 to 4 in-lbs torque). See Figure 3.
  8. Reinstall the terminal connectors to their original locations.

The transmitter module is mounted on the top of the display PC board partially under the LED display module. Visible when display removed from the bezel. Module FCC ID: VPYLBZY Part 15C 2. Unit is assembled from tested components, complete system not tested. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, under Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used by the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

  • Reorient or relocate the receiving antenna.
  • Increase the separation between the equipment and the receiver.
  • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
  • Consult the dealer or an experienced radio/TV technician for help.
