6.2 Verifying configuration with LOI
The optional LOI can be used for commissioning the device. The LOI is a two-
button design with internal and external/rear buttons. On a polished stainless
steel housing, buttons are located internally both on the display and terminal
side of the transmitter. On an aluminum housing, buttons are located on the
display and externally underneath the top metal tag. To activate the LOI, push
any button. LOI button functionality is shown on the bottom corners of the
display. See
Table 6-2
and
Figure 6-2
for button operation and menu
information.
