Actions Menu

Functions such as graphing, point logging, overriding, expanded information, setup, detailed status, and manual defrosting can be initiated from the Actions Menu box by

pressing the key from the Home screen or any sta-

tus screen. When you press the Enter key, only the options that are appropriate to the current field and application will be displayed; all others will be hidden.

For example, if Enter is pressed when a circuit is high- lighted, the Actions Menu would display all available options for that circuit, such as Manual Defrost, meaning that by selecting Manual Defrost the Manual Defrost screen would come up for that particular circuit.

12.4.2 Screen Types

Summary Screens

Summary screens let you view status information for multiple applications of the same type. For example, (Figure 12-9) is the Circuits Summary screen in the E2 RX controller. This screen shows the name, state, tem- perature, setpoint, alarm, refrigeration, and defrost infor- mation for all defined standard and case control circuits displayed. To see a more detailed status when on an appli- cation summary screen, highlight the desired application

from the list with the arrow keys and press . This will take you to the Status screen.

Status Screens

Status screens are real-time views of application func- tions. They show the current status of all outputs, the cur- rent values of all inputs, and other important data such as control setpoints, run times, and whether or not bypasses or overrides are active.

Each status screen is specially designed to provide a concise at-a-glance view of how one or more systems are functioning.
