PROGRAMMING
There are two ways to program the VF05.
−
Programming with the HyView software
−
Programming with the VGF-DISPLAY display unit

Installing and Running HyView
If necessary, install the “
HyView
HART Configuration Software” (hereafter
HyView).
Electrical connections: Connect the transmitter to a PC using a HART
USB modem (sold separately).
Start the program and search for the transmitter in the program.
5.1.2.
Programming and Configuring the Device
Select the device from the list of found devices to configure and program and open the device's "Device Programming" window.
All the necessary parameters and function settings can be performed with HyView. The table below summarizes the parameters and their location and path.

Description
Default value
Zero-level distance (P04),
Set container height
0...60 m
(0…
200 ft)
It provides the basis for level measurement calculations. The distance between the plane of the lower
sealing surface of the mechanical connector (the lower plane of the flange in the case of a flanged
version) and the reference point at the bottom of the tank. Its value must be set in a distance unit (Unit
- P00b).
Note: There is no measurement beyond the set zero distance if the output is configured for distance or
level measurement.

length (P03)
The dead zone is the distance between the plane of the lower sealing surface of the mechanical
connection (the lower plane of the flange in the case of the flanged version) and the highest level in the
tank. Signals generated within the dead zone are not processed. The current loop output does not follow
the dead zone level signal. Its value must be set in distance units (Length unit
–
P00b).

0 (limiter off) or the minimum measuring
distance. The distance between (P05) + 5
cm and the probe length (P03)
The maximum value of the measuring range of the device can be limited with this parameter. Signals
received beyond the set distance will not be processed. Its value is calculated from the plane of the
lower sealing surface of the mechanical connector (in the case of a flanged version, from the lower
plane of the flange).
Remote blocking can be turned off by setting the parameter to 0. In this case, the device will give a
valid result along the entire length of the sensor.

Damping time (P20)
Time constant
0…999 sec.
The "Damping time" is used to reduce undesired fluctuations (e.g.: rippling) in the display of the
measured data. If the level changes abruptly, the new value will be set to within 1% accuracy
(exponential setting). Unit of measure: seconds.

Probe length (P03)
0.
1…30 m
(0.33
…
100 ft)
The set value is the nominal probe 100 mm (+ 0.33 ft).
This value should only be changed if the probe length is changed or the probe is replaced.
Its value must be set in distance unit (Length unit - P00b). For special applications, the length of the
probe may be greater than the height of the tank but may not exceed 30 m (100 ft).

When the current output is set to "Fixed" mode (P12b = 1), the constant current set here is set. The PV
current transmission does not work, and at the same time, it overrides any current output fault indication.

The units that can actually be used (length, volume, weight) change according to the unit system set
according to this parameter. When setting or changing units, the unit system must be selected first and
only then can the actual unit to be used be set (according to the previously narrowed list).
