Chapter 1 Overview

Getting Started Quickly

The PM control has a page and menu structure that is listed below along with a brief description of its pur-

pose.

Setup Page
Push and hold the up and down keys (¿ ¯)

for 6 seconds to enter. (See the

Setup Page

for further information)

Once received, a user would want to setup their control prior

to operation. As an example, define the input type and set

the output cycle time.

Operations Page
Push and hold the up and down keys (¿ ¯)

for 3 seconds to enter. (See the

Operations

Page

for further information)

After setting up the control to reflect your equipment, the

Operations Page would be used to monitor or change run-

time settings. As an example, the user may want to see how

much time is left in a profile step or perhaps change the

limit high set point.

Factory Page
Push and hold the Infinity and the green Ad-

vance keys (ˆ

) for 6 seconds to enter. (See

the

Factory Page

for further information)

For the most part the Factory Page has no bearing on the

control when running. A user may want to enable password

protection, view the control part number or perhaps create a

custom Home Page.

Home Page
The control is at the

Home Page

when ini-

tially powered up.

Pushing the green Advance key

will allow the user to see

and change such parameters as the control mode, enable au-

totune and idle set point to name a few.

Profile Page
Push and hold the the green Advance key

for 6 seconds to enter. (See the

Profile Page

for further information)

If equipped with this feature a user would want to go here

to configure a profile.

The default PM loop configuration out of the box is shown below:

• Analog Input functions set to thermocouple, type J

• Heat algorithm set for PID, Cool set to off
• Output 1 set to Heat
• Control mode set to Auto
• Set point set to 75 °F

If you are using the input type shown above, simply connect your input and output devices to the control.

Power up the control and push the up arrow ¿ on the face of the control to change the set point from 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.

Note:

The output cycle time will have a bearing on the life of mechanical relay outputs and can be different based

on the type of output ordered. The output cycle time can be changed in the Setup Page under the Output

Menu.
