6 Service and maintenance
This Chapter provides standard maintenance information and instructions on how to remove and install components of the flow
computer.
It is recommend that a regularly scheduled maintenance program is established. Establishing a maintenance program can help
minimize downtime.
6.1.1 Cleanliness
Because a flow computer installation is primarily exposed to external environmental conditions, it is important that the equipment
be regularly inspected for cleanliness, both externally and internally, as damage may occur. Foreign contaminants can cause
damage to interior mounted components rendering flow computer inoperable.
6.2 Data preservation
Prior to performing maintenance on the flow computer, preserving and protecting data is very important. Data that should be
preserved includes:
— Measurement data
— Alarm and event records
— Station configuration files
— Calibration data
The following subsections provide instructions for ensuring that all data is protected and preserved.
6.2.1 Data collection
IMPORTANT NOTE: Collected data includes the measurement data, the alarm and event codes. For more details
click Help on the Collect screen.
To collect data:
Establish local communication with the XFC on the preferred port. See section 5.3, Establishing Initial Local
Communication or 5.4.2, Establish local point-to-point connection over Ethernet.
Click the Collect icon on the PCCU toolbar.
On the navigation tree, select all the desired measurement application instances in the device. If collecting all data,
select all check boxes.
Select the desired output types for the data. Data collected can be stored in files saved in the laptop used to perform
the collection,
Select the desired time range. For the data for the entire collection capacity select All Data.
Click Collect.
6.2.2 Back up configuration files (save)
IMPORTANT NOTE: Backup configuration files include both configuration and calibration data.
Although there are multiple reasons to backup station configuration files, this procedure will focus on preserving
the configuration files and calibration data for the purpose of restoring the flow computer following maintenance
and troubleshooting procedures.
To safeguard the station and calibration data, back up files to a laptop hard drive or disk before performing any maintenance
procedure. You can use backup files to restore the station and calibration data, allowing the flow computer to restart without the
need for reconfiguration.
