The copied data are permanently saved in an EEPROM memory in
the display and adjustment module and remain there even in case of
power failure. From there, they can be written into one or more sen-
sors or kept as backup for a possible electronics exchange.
Note:
Before the data are stored in the sensor, a check is carried out to
determine if the data fit the sensor. If the data do not fit, a fault signal
is triggered or the function is blocked. When data are being written
into the sensor, the display shows which instrument type the data
originate from and which TAG-no. this sensor had.
In this menu item you can select the type and size of your probe from
a list of all possible probes. This is necessary to adapt the electronics
optimally to the probe.
In this menu item you gain access to the protected area where
you can enter special parameters. In exceptional cases, individual
parameters can be modified in order to adapt the sensor to special
requirements.
Change the settings of the special parameters only after having con-
tacted our service staff.
The sensor offers the HART modes "Analogue current output" and
"Fix current (4 mA)". In this menu item you determine the HART mode
and enter the address with Multidrop mode.
In the mode "Fixed current output" up to 63 sensors can be operated
on one two-wire cable (Multidrop operation). An address between 0
and 63 must be assigned to each sensor.
If you select the function "Analogue current output" and also enter
an address number, you can output a 4 … 20 mA signal in Multidrop
mode.
With the mode "Fixed current (4 mA)" a fixed 4 mA signal is outputted
independently of the actual level.
