Sat, 4 High Sat, or 5 Preset Alarms and enter the desired new value which must fall within
the guidelines below:
• The low alarm value must be between 3.50 and 3.75 mA
• The high alarm value must be between 21.0 and 23.0 mA
The low saturation level must be between the low alarm value plus 0.1 mA and 3.9 mA for
the standard HART transmitter. For the safety certified transmitter, the lowest saturation
setting is 3.7 mA and the highest is 20.9 mA.
Example: The low alarm value has been set to 3.7 mA. Therefore, the low saturation level,
S, must be 3.8 ≤ S ≤ 3.9 mA.
The high saturation level must be between 20.5 and 20.9 mA.
Preset alarms can either be 1 Rosemount or 2 NAMUR-compliant. Use the failure mode
switch on the front side of the electronics to set whether the output will be driven to high
or low alarm in the case of failure.
3.9.3 HART output
HART 5 Fast Keys
HART 7 Fast Keys
The HART Output command allows the user to make changes to the multidrop address,
initiate burst mode, or make changes to the burst options.
3.9.4 LCD display options
HART 5 Fast Keys
HART 7 Fast Keys
The LCD display option command sets the meter options, including engineering units and
decimal point. Change the LCD display settings to reflect necessary configuration
parameters when adding a LCD display or reconfiguring the transmitter. Transmitters
without LCD displays are shipped with the meter configuration set to "Not Used."
