Chapter 3. Initial Setup and Programming
26 PanaFlow HT User’s Manual
3.2 User Restrictions (cont.)
Notice that, at the bottom of Figure 18, there are four options for “Save Changes?”. Selecting “No” will discard any
program changes and reset the instrument to restart Measure mode. The other three options are Active Settings,
Commissioned Settings, and Factory Settings. They allow the instrument to store three complete sets of program data.
Note:
The option to save as Commissioned Settings is only available if the operator has Service or Factory access
level. The option to save as Factory Settings is only available from the Factory access level.
The purpose of these extra data sets is to allow the instrument to be restored to those saved settings as a troubleshooting
measure. If at any point there is an error in the Active Data Set (the set of parameters used in Measure mode), the
Authorized User may revert the Active Data Set to the Commissioned Data Set. This will return the flowmeter to a
known working condition, the way it was programmed when a GE Service Professional first commissioned the product
on site. As a secondary redundant measure, the Authorized User may revert the Active Data Set to the Factory Data Set
if there is an issue with the Commissioning Data Set. This returns the instrument to the way it was programmed when it
was calibrated. Since the integrity of the SIL Output is so critical, the flowmeter maintains all three data sets in memory
as a backup in case of error.
