PM3/PM6 LEGACY™ Express PID Controller • 5 • Specifications

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

functions. An input and an output would be

considered external functions where the limit,

PID or alarm function would be an internal

function. Information ﬂows from an input func-

tion to an internal function to an output func-

tion 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), PID control, 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 func-

tions to properly accommodate the application

requirements.

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 thermocou-

ple 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 con-

nected to that input.

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 Function 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 Function Key Menu

(Set-up Page).

Figure 2: Thermocouple Input Wiring Example

PM3/PM6 LEGACY™ Express PID Controller • 6 • Specifications

(Overview Continued)

Internal Functions

The controller will use input signals to calculate

a value and then perform an operation. A sam-

ple 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 deter-

mine 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 they can be

conﬁgured to respond to an alarm. If conﬁg-

ured 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.

Figure 1: PM6 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.

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

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
