Table 2-2: Alarm and Saturation Values
High
Additional considerations when using custom alarm and saturation values:
• Low alarm must be less than low saturation
• High alarm must be higher than high saturation
• Alarm and saturation levels must be separated by at least 0.1 mA.

Additional configuration

The following items are considered optional and may be configured as needed.
Refer to
2.5.1 Local display
Fast Keys
A local display is available as an orderable option on the primary transmitter. The display
will show a 0–100 percent scaled bar graph, the selected measurements from
and any diagnostic or error messages. At least one parameter from
selected. If more than one item is selected, the display will scroll through the selected
parameters, showing each for three seconds.

2.5.2 Burst mode
Fast keys
When configured for Burst mode, ERS provides faster digital communication from the
system to the control system by eliminating the time required for the control system to
request information from the system.
When in Burst mode, the system will continue to output a 4–20 mA analog signal. Because
the HART
value can drive other equipment in the loop while the control system is receiving the
digital information. Burst mode applies only to the transmission of dynamic data (process
variables in engineering units, primary variable in percent of span, and the analog output
reading), and does not affect the way other transmitter data is accessed.
Access to information that is not burst can be obtained through the normal poll/response
method of HART communication. A communication device, AMS Device Manager, or the
control system may request any of the information that is normally available while the
system is in Burst mode.
