Procedures

Prior to all component replacement procedures, the following sections must be
completed:
— 3.1 Preserving data and configuration files
— 3.2 Disconnect power
Completion of these two sections indicates that all files have been protected from a
loss of power and that the flow computer has been powered down and is deemed
safe.
3.1

Preserving data and configuration files

If local communication is still possible, collect data from the flow computer and back
up the station configuration files.
To back up the station files:
1. Collect all data. Use the Data collection procedure detailed in the user manual
listed earlier in the Additional information section of this guide.
2. If not previously done, update the TFCold (Cold) configuration with the running
(warm) configuration. Use the Delete and Re-create TFCold function of the
Update TFCold Start Configuration procedure which is detailed in the user
manual listed earlier in the Additional information section of this guide.
3. Back up all device software to the host computer operating PCCU32 software.
Use the Save the TFCold (Cold) configuration to the PC procedure detailed in
the user manual listed earlier in the Additional information section of this guide.
3.2

Disconnect power

CAUTION – Equipment damage. The external power/charger and
battery connections must be removed before removing all other cables,
boards, and field connections. Connecting or disconnecting cables and
wires on the electronic board while power is applied can damage the
electronic components.
To disconnect power from the µFLO
