11.9.7 How does the AFC Manager transfer the configuration to the
module?
You can configure the site and meter parameters at the local PC saving the
project as a .AFC file. You may then download the configuration by clicking on
Project / Download Configuration
. In this case, all configuration will be
downloaded from the local PC to the module, except for the Virtual Slave Re-
mapping (must be written separately).
Once you download the entire configuration, you may perform smaller
adjustments (Site Configuration and Meter Configuration) by clicking on the Write
button.
11.9.8 What is the password used for?
The password protects the module from any changes to "sealable" parameters.
Sealable parameters directly affect measurement calculations (for example,
orifice diameter, or K-factor).
The password is stored in the module so different computers should always use
the same password.
11.9.9 Why do I receive an Illegal Data Value warning when I try to
write a meter configuration or download the entire
configuration to the module?
Follow these steps:

Ensure that any parameters you had changed (from the default configuration)
are acceptable according to applicable standards. The white rectangle (Site
Configuration and Meter Configuration) shows the correct range of values for
each parameter.
 The module will not accept a downloaded configuration that changes the
meter type and/or the product group of a meter that is currently enabled.
Disable the meter first, then proceed with the meter download.
 Look at the number of events currently stored in the module. You can check
this using Monitor / Event Log and then click on the Read button. If the
number of events not yet downloaded
is 1999 it means that the event log is
full. In this case, if the project also has the event log unlocked option clear,
the module will not accept any further configuration downloads generating the
Illegal Data Value
at any attempt. Delete all events from the module event
buffer (refer to the Event Log section). You may want to select (check) the
Event Log Unlocked
check box. This setting allows the module to overwrite
the oldest event from the buffer when the buffer is full.
11.9.10 Why is the Molar Analysis button disabled?
In order to transfer the molar analysis values between the module and the local
computer, it is required that the module’s configuration and the configuration at
the local computer should match. In order to accomplish this, you can perform
either a Meter Configuration / Read or a Meter Configuration / Write
operation.
