Fast Keys
The factory default LCD display setting is engineering units. The Meter
Options command allows customization of the LCD display to suit application
requirements. The LCD display will alternate between the selected items (up
to four may be chosen):
• Pressure (Engineering Units)
• Percent of Range
• Scaled Variable
• Temperature
AMS v7.0
Right click on the device and select "Configure" from the menu.
1. In the "LCD" tab, select the desired options to suit your application
needs, click Apply.
2. After carefully reading the warning provided, select yes.
3051S transmitters automatically and continuously perform self-diagnostic
routines. If the self-diagnostic routines detect a failure, the transmitter drives
the output to configured alarm values. The transmitter will also drive the
output to configured saturation values if the applied pressure goes outside the
4-20 mA range values.
The transmitter will drive its output low or high based on the position of the
failure mode alarm jumper, see "Configure Security and Alarm" on page 2-13.
NOTE
The failure mode alarm direction can also be configured using the HART
Communicator or AMS.
3051S transmitters have three configurable options for failure mode alarm
and saturation levels:
• Rosemount (Standard), see Table 3-1.
• NAMUR, see Table 3-2.
• Custom, see Table 3-3.
