– Tag
The tag may be used to mark a specific transmitter. It can comprise up to
8 alphanumeric characters. It can also serve as an address, in order to read the
unique identifier using HART command #11 ("Read Unique Identifier associated
with Tag"), from the transmitter, even if the polling address is unknown.
This presumes that an unambiguous tag has been configured before.
● Select the menu items » Settings «, » Communication «, » Hart interface « and
» Tag « in this order, pressing the » « key after each selection.
● Use the » « and » « keys to set each position of the tag and press the » «
key to confirm the setting.
● Press the » « key to confirm the complete tag.
Analogue interface
This group contains the functions needed for the test and setting functions.
Settings for the analogue interface
– Analogue set point / Set measurement range
When the measuring range of the analogue interface must be adjusted.
Here corresponds: 0 ppm = 4 mA; Analogue signal = 20 mA
— According to the standard, the standard measuring range of the sensor automat-
ically ends here.
– Warning on/off
This function is used to switch the warning signal » « on the analogue interface
on and off. If the presence of a warning is to be signalled via the analogue interface,
the warning signal must be switched on. In the case of a warning, the current on the
analogue interface is switched for one second to the state "Warning". For the rest of
the time, the measured signal is transmitted. The interval between the warning sig-
nals and the level of the analogue signal can be configured as desired, see "Warning
signal" on page 71 and "Warning level" on page 71.
● Select the menu items » Settings «, » Communication «, » Analogue interface «
and » Warning on/off « in this order, pressing the » « key after each selection.
● Select » Enable « or » Disable « and press the » « key to activate.
