1.3.6.2 Signal lamps
For the purpose of signalling various operating states, the panel contains six
fields with symbols and a signal lamp for each.
The heating (gas sampling hose) is switched on

1.3.6.3 Display
The display is made up of two rows and is backlit.
The measurement variables called using the keyboard are displayed
together with their dimensions in the bottom line. The top line shows the
operating status or error messages, depending on the current conditions.
During programming, the display is used for interaction with the user.
Appropriate displays, messages and questions are displayed. The line at the
top shows the menu that is open, while the line at the bottom shows the
function to be programmed or a value to be changed.
1.3.7 Interfaces
Two electrically isolated analogue current outputs are available for the
purpose of evaluating and processing the measured values.
You can allocate any humidity measurement variables or auxiliary variables
to these outputs as you wish.
You are free to define the limits of the measurement ranges within the
respective overall measurement range as you wish (see 5.2.1).
The analogue outputs are constantly monitored to ascertain whether the
current measured value lies within the respective measurement range that
has been programmed. If there are deviations, a fault is reported.
In addition, one of the two analogue current outputs can be monitored to
ascertain whether it adheres to a minimum value and maximum value.
Once they have been switched on, the outputs remain at 0 until the normal
operating conditions are reached.
If a fault is reported during measurement operation, the outputs are fixed at
the value that they had directly before the fault report appeared.
Field bus interface (PROFIBUS DP).
All measured values can also be recorded using the field bus interface. In
addition, the system can be configured using this interface.
