Section 4: Service and Troubleshooting
This section covers the following topics:
 Returning the Unit for Repairs
 Interpreting the Status LEDs
 Switch and Buttons
 Removing/Replacing the HMI Module
 Replacing the Main Battery Pack
 Removing/Replacing the SRAM Battery
 Upgrading System Firmware
To maintain hazardous location certifications, you can only replace components in the field with
the exact same part so that the model string on the data plate remains correct. This means you
cannot add any hardware not reflected in the model string or upgrade a hardware component to a
newer version; any such upgrades are prohibited and void the hazardous location certification.
For a list of user serviceable parts contact your Emerson Remote Automation Solutions sales
representative or Emerson Impact Partner.
This chapter describes the service tasks that everyone needs to know such as replacing batteries or
installing a firmware upgrade. A separate series of field replacement guides covers major field
replaceable components.
Any replacement not covered in this chapter or in the field replacement guides (such as adding or
upgrading hardware or replacing sensors) can only be performed at an Emerson-authorized repair
facility.
Important
Use only batteries supplied with the flow computer or sold by Emerson as spare parts for this flow
computer. If you substitute a battery you obtain elsewhere you will void your certification unless it is
the identical part from the same manufacturer as that supplied with the flow computer from
Emerson.
