MAINTENANCE

Running a Self
Test
When you add new device descriptions and system
software to your 375 Field Communicator, more space
on your System Card is used. Over time, your System
Card will become full and there will not be enough
memory to add new files.
You can use the System Card Memory Management
feature in the Easy Upgrade Programming Utility to free
space on your System Card. This feature lets you select
which device descriptions can be downloaded. Reducing
the number of DDs on a System Card can save a
significant amount of space. For example, if your site
uses only HART devices, use Memory Management to
ensure only device descriptions for these devices are
downloaded to your System Card. See the Easy
Upgrade Programming Utility help for details.
Any maintenance, repair, or replacement of components
not listed below must be performed by specially trained
personnel at authorized service centers. You can
perform common maintenance procedures on the 375
Field Communicator, as described below:
• Cleaning the exterior. Use only a dry, lint-free towel or
dampen the towel with a mild soap and water solution.
• Charging, removing, and replacing the battery.
• Removing and replacing the System Card.
• Removing and replacing the Expansion Module or
Expansion Port Plug.
• Removing and replacing the stand assembly.
• Ensuring that all exterior screws are sufficiently
tightened.
• Ensuring that the Communication Terminal recess is
free of dirt and debris (does not require disassembly).
There is no need, nor is it possible, to perform a manual
self test with the 375 Field Communicator. Testing
features are done automatically. A warning message
appears if a fault condition is found during these tests.
