Navigating the Profiling Page

Note:

Some of these menus and parameters may not appear, depending on the controller's options. See model

number information in the Appendix for more information. If there is only one instance of a menu, no sub-

menus will appear.

Profile Setup

First, consider some foundational profile setup features that once configured, will apply to all configured pro-

files.
The screen shot below (EZ-ZONE Configurator software) graphically shows the settings (shaded green)that

will apply to all profiles; e.g., if Guaranteed Soak is not enabled here this feature will not be available in any

individual profile configuration.
Some of those features that apply to all profiles 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 process 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 cor-

responding 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 will also have an immediate impact on the running

profile. Some parameters in the Profile Status Menu can be changed for the currently running profile, but

should only be changed by knowledgeable personnel and with caution. Changing parameters via the Profile

Status Menu will not change the stored profile but will have an immediate impact on the profile that is run-

ning.

Once these global profile features are configured, the next step will require navigation to the Profiling Page.

Here, each desired ramp and soak profile will be configured.
