Commissioning
8.1
General remarks
In case of corresponding order the transmitter is ready for
operation after mounting and installation of the connections.
The parameters are set at the factory.
The connected lines must be checked for firm seating. Only
firmly seated lines ensure full functionality.
8.2
Checks prior to commissioning
The following points must be checked before commissioning
the device:
— The wiring must have been completed as described in
chapter "Electrical connections" on page 8.
— The ambient conditions must meet the requirements set
out on the name plate and in the Datasheet.
8.3
Basic Setup
Communication with the transmitter takes place using the
HART protocol. The communication signal is modulated onto
both wires of the signal line in accordance with the HART FSK
"Physical Layer" specification.
The electrical connection is provided at the (+) and (–)
terminals of the transmitter or by the power supply cable that
is installed on-site. The advantage of this is that remote
configuration is possible with supply units that are part of the
industrial plant.
The following configuration types are available for the
transmitter:
— With the handheld terminal
The connection of the cable for the handheld terminal is
performed without polarity. The transmitter can also be
configured via the HART protocol during normal operation.
— With
DTM
Configuration can be performed within an FDT frame
application that is approved for use with the DTM.
— With
EDD
Configuration can be performed within an EDD frame
application that is approved for use with the EDD.
