1. Loosen the certifications label screw and slide the label to expose the zero
adjustment buttons.
2. Set the 4 mA point by pressing the Zero button for two seconds. Verify the
output is 4 mA. The optional LCD display will show ZERO PASS.

7.0 Safety Instrumented Systems (SIS)

The following section applies to Rosemount 3051C Transmitters used in SIS
applications.
7.1 Installation
No special installation is required in addition to the standard installation practices
outlined in this document. Always ensure a proper seal by installing the
electronics housing cover(s) so that metal contacts metal.
The loop must be designed so the terminal voltage does not drop below 10.5 Vdc
when the transmitter output is 22.5 mA.
Position the security switch to the ON position to prevent accidental or deliberate
change of configuration data during normal operation.
7.2 Configuration
Use any HART-compliant master to communicate with and verify configuration of
the Rosemount 3051.
User-selected damping will affect the transmitters ability to respond to changes
in the applied process. The damping value + response time must not exceed the
loop requirements.
Note
1. Transmitter output is not safety-rated during the following: configuration changes,
multidrop, loop test. Alternative means should be used to ensure process safety during
transmitter configuration and maintenance activities.
2. DCS or safety logic solver must be configured to match transmitter configuration.
