Series F4S/D Operation
The Series F4S/D controller can function as either
a static set point controller or as a profile con-
troller. The information shown on the Lower Dis-
play during operation (the Main Page) is pro-
grammable and can be customized to support both
modes of operation. (See Setup Page.)
In either the static set point mode or the profile
mode, the Series F4 can only be operated in a
closed-loop configuration. Manual operation (open-
loop) mode is not allowed.
Static Set Point Control
The Series F4 is in static mode when it is not con-
trolling a ramping profile. When in static mode:
• The Profile Indicator Light is off.
• The Upper Display shows the actual process
temperature of input 1, 2 or 3 depending upon
Setup Page configuration.
✔ NOTE:
All control activity stops when you enter the Setup Page,
Analog Input, Digital Input, Control Output, Alarm Out-
put, Retransmit, and Digital Output menus.
• The Lower Display shows the default or user -
configured information set. See the Setup
Chapter for instructions in programming the
Main Page to display the information you want.
To operate the Series F4 as a static set point con-
troller, use the navigation keys (> < , . ) to
select the preferred channel and adjust the set
point.
Limits may be placed on the set point in the Set
Point Low Limit and Set Point High Limit parame-
ters (Setup Page > Analog Inputx).
Setting the set point to Set Point Low Limit minus
1 (-1) will turn control Output 1 off and display the
set point as off.
