Custom Main Page
The Main Page shows error messages; input and output
status; and allows access to controller software. You can
customize the Main Page to display chosen information
by going to the Setup Page, Custom Main Page Menu.

Auto and Manual Operation
The Series F4P controller can function as a static set
point controller (auto mode); or the user can directly
control the outputs (manual mode).
In the static set point mode, the Series F4P can only be
operated in a closed-loop configuration.
The Auto/Manual Indicator Light is on when the con-
troller is in manual mode. To toggle between manual and
auto mode, first press the Auto/Manual key
å , then con-
firm your selection in the lower display. The indicator
light will flash after you press
å until you confirm your
choice or 10 seconds have elapsed. While in manual mode
you can adjust the output power level for process outputs
or turn relay or open collector outputs on or off.
ç WARNING: Only authorized and qualified personnel
should change the set point on the controller. Failure to
comply with these recommendations may result in dam-
age to equipment and property and injury to personnel.
Static Set Point Control
When the Series F4P is in static set point mode:
• The Upper Display shows the actual process temper-
ature of input 1.
• The Lower Display shows the default or user-config-
ured Main Page.
To operate the Series F4P as a static set point controller,
select SP1 in the Main Page then use the Up and Down
keys to adjust the set point.
Limits may be placed on the set point in the Set Point
