Navigating the Profiling Page
Note:
Some of these menus and parameters may not appear, depending on the controller's op-
tions. See model number information in the Appendix for more information. If there is
only one instance of a menu, no submenus will appear.
Profile Setup
First, consider some foundational prole setup features that once congured, will apply to
all congured proles. The screen shot below (EZ-ZONE Congurator software) graphically
shows the settings (shaded green)that will apply to all proles; e.g., if Guaranteed Soak is
not enabled here this feature will not be available in any individual prole conguration.
Some of those features that apply to all proles are listed below with a brief description of
their function.
- Ramping Type (Time or
Rate) which changes the
profile set point based
on a set interval of
time or set rate.
- Profile Type (Set Point
or Process) determines
whether a step (any
step changing the set
point) of a profile will
begin by using the pro-
cess value (Process) or
the last closed-loop set
point (Set Point).
- Guaranteed Soak En-
able, when set to on
makes this feature avail-
able in all profiles. If
Guaranteed Soak Enable
is on, use Guaranteed
Soak Deviation 1 to 2 to set the value for the corresponding loop. Set the deviation or band
above or below the working set point where this condition must be met before the profile
can proceed.
Note:
Changes made to profile parameters in the Profiling Pages will be saved and take effect
on the next pass through the step. Changes made in the Profile Status page effect the cur-
rent step being executed and do not update the step setting in the profiling page. Chang-
ing profiles should only be changed by knowledgeable personnel and with caution.
