8.6.10

Failsafe (PROFIBUS PA only) (4.1.9.)

Failsafe Mode (FS MODE) (4.1.9.1.)
Fail-safe Mode occurs if the status of the input value is bad, or if the device has been put into
Fail-safe mode using Simulation. One of three options can be selected for the material level
to be reported when the LOE timer expires.
Options
Failsafe Value (FS VALUE) (4.1.9.2.)
(Accessible in PDM only after FS VALUE is selected in Fail-safe Mode). User-defined default
value for the OUT parameter, if sensor or sensor electronic fault is detected. Units are the
same as the OUT value.
Vales
8.6.11

Human interface (INTERFACE) (4.1.A)

Decimal Point (DECIMAL) (4.1.A.1.)
The number of digits to display after the decimal point. (The LCD is limited to displaying three
decimal places.)
Out unit text: If the code list does not contain a desired unit for the OUT parameter, (see
General Requirement) you can write the specific text in this parameter.
8.6.12

Analog input function block 2 (AIFB 2) (4.2.)

AIFB 2 parameters are identical to AIFB 1 parameters. See Analog input function block 1 (AIFB
1) (Page 95).
8.6.13

mA output (HART only) (4.3.)

The mA output is provided by Analog Input Function Block 1 (AIFB1). You can enter a user-
defined mA value, either for simulation, or to perform a mA Trim.
To set these parameters via PDM, see Parameters accessed via pull-down menus (Page 62).
