External Ground Screw Assembly
The external ground screw assembly can be ordered by specifying code G1 when an enclosure is
specified. However, some approvals include the ground screw assembly in the transmitter
shipment, hence it is not necessary to order code G1. The table below identifies which approval
options include the external ground screw assembly and which do not.
Configuration Transmitter Configuration
The transmitter is available with standard configuration setting for
FOUNDATION fieldbus (see “Custom configurations are to be specified when
ordering. This configuration must be the same for all sensors. The following
table lists the necessary requirements to specify a custom configuration.”).
The configuration settings and block configuration may be changed in the field
with DeltaV®, with AMS, or other FOUNDATION fieldbus host or
configuration tool.
