Getting Started Quickly
The PM control has a page and menu structure that is listed below along with a brief descrip-
tion of its purpose.
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
Press and hold the up and down keys (¿
¯) for 3 seconds to enter. (See the Op-
erations Page for further information)
After setting up the control to reflect your
equipment, the Operations Page would be used
to monitor or change runtime settings. As an
example, the user may want to see how much
time is left in a profile step or perhaps change
the high set point of the limit.
Factory Page
Press and hold the Infinity and the green
Advance 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
initially powered up.
Pushing the green Advance Key ‰ will allow
the user to see and change such parameters as
the control mode, enable autotune and idle set
point to name a few.
Profile Page
Press and hold 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 conguration 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.
