Navigating and Understanding the User Interface
Home Screen
After powering up the controller a white screen will appear first while initializing. It will then go
blank for a short time before the Watlow F4T logo appears. Once the startup process is
completed the Home Screen will be presented. The image below shows the Home Screen while a
profile is running.
①
Controller Status:
Indicates alarms and errors if they occur. The current security level is
shown as “User” (see “Security” section). Also indicates if Data Logging is enabled (REC is
enabled in this image) and if a USB thumb drive is plugged into the USB host port (USB icon is
present in this image, indicating that a thumb drive is plugged in). The button shown in the
center of the status bar allows you to view alarm and error messages when pressed.
②
Profile Status Bar:
Provides visibility and information pertaining to running profiles as
well as access to available profile actions (see “Creating and Editing Profiles” section).
③
Vertical Ellipsis:
Displays current control mode while also providing access to other
operational parameters such as the Ramp to Set Point, Autotune, PID Settings, and more (see
“Changing Loop Operational Parameters” section).
④
Next Page:
Home screen has been setup to display multiple pages (loops). The left and
right arrows on each side of the home screen provides navigation from one to the other (see
“Personalizing the Home Screen” section). Model 101H is configured by TestEquity to have
three screens. The first one shows Temperature and Humidity (as pictured above). The second
one shows Temperature Only. The third one shows Humidity only.
