AMS
Right click on the device and select “Configuration Properties” from the menu.
1. In the “Device” tab, locate the “LCD Display Configuration” area. Select
the desired options to suit your application needs, click Apply.

DETAILED SETUP
Failure Mode Alarm and
Saturation
4500 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 switch, see “Set Switches” on page 2-5.
NOTE
The failure mode alarm direction can also be configured using the HART
Communicator or AMS.
4500 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
