These values extrapolate the maximum value that can be shown by the display. Using the HMI, you can set up to the limit of 19999. When configured via
NXperience
, these parameters
can be adjusted up to the values shown on the table above, but when accessing these parameters via the HMI, they will display the value

Transmitters
have two alarm outputs, which can also be used with ON/OFF control outputs. For models with display,
there is the additional feature of an internal buzzer for audible signaling. For each alarm output and for the buzzer, the following can be configured:
•
The associated psychrometric property;
•
