Hardware settings
Write protect mode
Changes can be prevented to the transmitter configuration data with the write protection electronics dip
switch 2. If the transmitter write protection is activated the transmitter will not accept any writes to its
memory. Configuration changes, such as trim and reranging cannot take place. In case the Digital LCD
Integral Display is installed (no access to switch), the Write protect mode can also be set by HART command
using the HHT and the PC. Please refer to the device manual and Software instruction for the right
operation.
Position the right dip switch in ON to prevent accidental or deliberate
change of configuration data.
Position the right dip switch in OFF to change the configuration data. If
data configuration is not allowed check the Software Write lock using
the HHT or PC.
Change the failsafe direction
The transmitter alarm direction is set by repositioning the electronics dip switch 1. The output value is in
accordance with NE43 NAMUR recommendations.
