COMMISSIONING
To commission the 3051S Safety Certified Transmitter, use the HART “Menu
Tree” on page 3-5 and “Fast Key Sequence” on page 3-6.
NOTE
Transmitter output is not safety-rated during the following: configuration
changes, multidrop, and loop test. Alternative means should be used to
ensure process safety during transmitter configuration and maintenance
activities.
For more information on the 375 Field Communicator see document
00809-0100-4276. AMS help can be found in the AMS on-line guides within
the AMS system.
Damping User-selected damping will affect the transmitters ability to respond to
changes in the applied process. The
damping value + response time
should
not exceed the loop requirements.
Fast Key Sequence - 1, 3, 6
Alarm and Saturation
Levels DCS or safety logic solver should be configured to match transmitter
configuration. Figure 6-1 identifies the three alarm levels available and their
operation values.
Figure 6-1. Alarm Levels
Setting the alarm values and direction varies whether the hardware switch
option is installed. You can use a HART master or communicator to set the
Alarm and Saturation values.
