3 Introduction to configuration and
commissioning
3.1 Security and write protection
The transmitter has several features that can help to protect it against intentional or unintentional access and
configuration changes.
• When enabled, the software setting Write Protection prevents any configuration changes. When
enabled, a lock icon displays at the top of the home screen of the display.
• When enabled, the display option Display Security prevents any configuration changes being made from
the display unless the display password is entered. Display Security does not prevent configuration
changes from other interfaces.
3.1.1 Enable or disable software write protection
When enabled, Write-Protection prevents changes to the transmitter configuration. You can perform all
other functions, and you can view the transmitter configuration parameters.
Write protection is enabled by toggling the physical write protect (dip) switch (identified by a lock icon)
located behind the display module.
