OVERVIEW This section outlines a technique for checking out the components, a method
for disassembly and reassembly, and a troubleshooting guide.
NOTE
Maintenance of traceability of replacement parts is the responsibility of the
user (see “Important Notice” on page 6-13 and Important Notice at beginning
of this manual, preceding Table of Contents).
The Rosemount 1153 Series D has no moving parts and requires a minimum
of scheduled maintenance. Calibration procedures for range adjustment are
outlined in Section 3, Calibration. A calibration check should be conducted
after inadvertent exposure to overpressure, unless your plant considers this
factor separately in the plant error analysis.
Test terminals are available for in-process checks. For further checks, the
transmitter can be divided into three active physical components: the sensing
module, the amplifier board, and the calibration board.
An exploded view of the transmitter is provided in Figure 5-2 on page 5-7. In
the following procedures, numbers in parentheses refer to item numbers in
the exploded view.
SAFETY MESSAGES Instructions and procedures in this section may require special precautions to
ensure the safety of the people performing the operations. Information that
raises potential safety issues is indicated by a warning message. The
following warning messages appear in this section.
Use only the procedures and new parts specifically referenced in this
manual to ensure specification performance and certification compliance.
Unauthorized procedures or parts can render the instrument dangerous
to life, limb, or property.
