Emerson E2 Manuel D’Utilisation

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.

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 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.
