Path to parameters:
“Device settings” / Outputs” tab
Current loop output (P12b),
Set mode
Selectable values:
−
Auto
− Manual
Selects the current loop output mode when transmitting current. In “Auto” mode, the output current
changes proportionally to the PV (4… 20 mA). In the case of “Manual,” the constant current set in the
parameter P08 is forced to the current output mainly for testing purposes.

Current loop output (P12a),
Value of output current if there is
an error (error current)
Selectable values:
− Hold
−
3.8 mA
−
22 mA
This parameter determines the state that the current loop output draws in the event of a fault. For “Hold,”
it keeps the last measured value (4… 20 mA), for “3.8 mA” and “22 mA” it keeps the indicated value until
the fault is present.
HyView setting: “ Device Settings ” > “ Outputs ” > “ Current output -> Error indication by the current
output”

Hold
Value assigned to 4 mA
(P10)
Selectable values:
In accordance with the PV adjustment
range, usually minimum value
PV value assigned to 4 mA in current transmission mode (usually the lower limit of the measuring
range for level measurement).
HyView setting: “ Device Settings ” > “Outputs” > “ Assignment of 4 mA - PV”
VGF-DISPLAY:
MAIN MENU / OUTPUT SETUP / ANALOG OUTPUT / 4mA VALUE
0.000 m (0.000 ft)
Value assigned to 20 mA (P11) Selectable values:
In accordance with the PV adjustment
range, usually maximum value
PV value assigned to 20 mA in current transmission mode (usually the upper limit of the measuring
range for level measurement).
HyView setting: “ Device Settings ” > “Outputs” > “ Assignment of 22 mA - PV”
VGF-DISPLAY:
MAIN MENU / OUTPUT SETUP / ANALOG OUTPUT / 22mA VALUE
6.000 m (20.000 ft)
Echo loss handling (P28b),
Error signal delay
Selectable values:
No delay
−
10 sec
− 20 sec
−
30 sec
−
1 min
−
2 min
−
5 min
− 15 min
This parameter determines the time elapsed between the occurrence of the fault and the error signal (e.
g.: fault current). The output is held at the time of the delay, based on the last valid measured data. The
function is only available for current output with an error signal set to the lower (3.8 mA) or the upper
(22 mA) error current.
HyView setting: “ Device Settings ” > “Measurement optimalization” > “Error delay”

Special, identifying data
Path to parameters:
“Device programming window (Advanced mode) / Special” tab
HART short address (P19),
Device address
0…15
Unique device address based on which the device can be identified and managed via the HART bus.
•
0: analog output active (current loop transmission active, 4…20 mA )
•
1…15: analog output inactive (no current loop transmission, constant 4 mA), Multidrop
HyView setting: “ Device Settings ” > “ Device identification ” > “ Device short address ”

RELAY mode (P13a),
RELAY output modes Selectable values:
−
OFF
−
PV
−
On Error
The operating mode of the RELAY with optional level switching functions can be set with this parameter.
The function is Off by default. When set to “PV,” the RELAY operates based on the trigger and release
values set according to the PV. The “On Error” setting allows a switched (relay contact) fault indication
to the process controller.
HyView setting: “ Device Settings ” > “Outputs” > “Relay mode”
VGF-DISPLAY:
MAIN MENU / OUTPUT SETUP / RELAY OUTPUT / RELAY MODE

RELAY mode (P13b),
RELAY functions
Selectable values:
−
Hysteresis
−
Window comparator
The basic switching methodology of the RELAY set to “PV” mode can be set .
HyView setting: “ Device Settings ” > “Outputs” > “Relay function”

MAIN MENU / OUTPUT SETUP / RELAY OUTPUT / RELAY FUNCTION
Hysteresis
RELAY mode (P13c),
RELAY inverted mode
Selectable values:
−
Not inverted
−
Inverted
If the setting is non-inverted, the RELAY closes its contacts when the trigger value is reached, otherwise
(inversion) opens these contacts.
HyView setting: “ Device Settings ” > “Outputs” > “Relay inverted”
VGF-DISPLAY:
MAIN MENU / OUTPUT SETUP / RELAY OUTPUT / INVERTING
Not inverted
RELAY trigger value (P14) Value can be adjusted in accordance with
PV setting interval
The measured PV value at which reaching the upper limit (upper switching value) is signaled on the
RELAY output.
HyView setting: “ Device Settings ” > “Outputs” > “Energized value”
VGF-DISPLAY:
MAIN MENU / OUTPUT SETUP / RELAY OUTPUT / ENERGIZED VALUE
1.000 m (3.300 feet) (level)
RELAY release value (P15) Value can be adjusted in accordance with
PV setting interval
The measured PV value at which reaching the lower limit (lower switching value) is signaled on the
RELAY output.
