and time on which the reset occurred will be shown beside 
the report priority.

The FSD can be used to handle alarms. Information 

such as time stamp, alarm ID string, current status, the rea-
son an alarm was triggered, (if a case temp limit was 
exceeded) configured priority of the advisory, Return-To-
Normal information, and if available, the limit that was 
exceeded can be viewed through the FSD. Alarms cannot 
be configured from the FSD unit. 

If more than one E2 controller is at a site, one E2 must 

be set up as the alarm annunciator for that site. The FSD 
will receive alarms from that alarm-annunciator E2 for the 
entire site. The FSD will point only to a single E2 at a site 
(it will not poll multiple controllers for alarms). For more 
information, refer to the FSD Manual (P/N 026-1400).

There are two basic forms used by the E2 to display 

data: logs and graphs.

A log is simply a list of sampled values for a particular 

input or output along with the sampling times and dates. 
When you view logged data in this form, it is usually listed 
with the most recent sample at the top of the list, and the 
other samples listed below it in reverse chronological 
order.

A graph is a graphical representation of these log 

entries that shows how the sampled value has changed 
over time. Graphing is a quick, easy way to get an idea of 
how the application has been behaving. Special graphing 
features also allow you to zoom in on specific areas of the 

graph.

The easiest way to access a log or graph is from the 

Actions menu while on the Home screen or an applica-
tion’s Status screen. These screens contain a number of 
different input and output values from the application. If a 
particular input or output is being logged by the E2 and 
has log data stored in the system, you can view the log or 
graph by following the instructions below:

1.

Use the arrow keys to highlight the desired input 
or output on the Home or a Status screen.

2.

Press 



 to call up the Actions Menu, and 

select either option 



 to view a graph or 



 to 

view a log.

If Graph and Log options are not listed in the Actions 

Menu, this means the property you have selected is not set 
up to be logged.

It may also be the case that there are currently no 

logged values to be viewed (this often happens when a 
controller is first set up or after a log has been cleared). If 
this is the case, E2 will tell you that no logged samples 
exist. For a complete list of items in the Actions Menu, 
refer to Section 10.7.3, The Actions Menu.
