9.4 HMI as diagnostic indicator
While the HMI works as Variable Indicator, also diagnostic
strings can be displayed. Whenever a failure or warning
condition is detected within the transmitter, a message appears
in the low side of the display below the bar-graph. The
message is formed by the NAMUR NE107 icon and the string
of the component where the problem occurred.

9.5 HMI as feedback of the local push button
operations
As consequence of the operations described in the section 8.2,
when the Z or S buttons are released, the feedback of the
executed operation is displayed in the bottom of the LCD
(same position as per diagnostic messages):
