Description
2.1.5.0
APPLICATION
2.1.5.1.0 THRESHOLD
2.1.5.1.1 LEV. PULSE AMP.
Read only value.
Dynamic value.
Amplitude of level pulse in millivolts.
2.1.5.1.2 LEV. PULSE GAIN
Read only value.
Dynamic value.
Amplification of level pulse (gain 0, 1, 2, or 3).
2.1.5.1. THRESHOLD
Enter a value from 50mV to
25000mV
Threshold of the level pulse (in millivolts). The threshold evolves in terms of
gain amplification factor changing by the electronic converter.
500 mV G3 at 1000 mm
2.1.5.2
DISTANCE INPUT
Enter a value from Function
2.1.1.4: Dead zone to Function
2.1.1.2: Probe length
This function forces the VF04 2-wire to search for the product surface in a zone
other than the actual measuring zone. If there is no level signal, you can enter
an estimated value.
2.1.5.3
DETECTION DELAY
Enter a value 0mm or 0in to
Function 2.1.1.4: Dead zone
This function forces the instrument not to analyse reflections in a zone directly
below the flange.
The entered value of the detection delay must be smaller than the "dead zone"
value.
As per order
2.1.5.4
SEARCH PROBE END
Measured in the units configured
in Function 2.1.2.1.1
Measures automatically the probe length.
The tank must be empty and the tank height must be configured to a value
greater than estimated probe length for this to be done correctly.
2.1.5.5
RESET VF04 2-wire
Restarts the VF04 2-wire.
2.1.6.0
SERIAL I/O
2.1.6.1
ADDRESS
Enter 0 to 15
Sets the address of the device when this latter is connected on a HART
Multidrop networks.
The current output drifts to 4 mA.
0 = 4 … 20 mA output current active
1 – 15 = in multidrop mode
0
2.1.7.0
STRAP TABLE
2.1.7.1
VOLUME UNIT
Select m3, l, US Gal, Ft3, bbl,
M3/h, Ft3/h, kg,
Metric Tons, US Tons
Unit for conversion values ("volume table").
The selected unit is used to define the strapping table values.
Litre [l]
2.1.7.2
INPUT TABLE
0 to 20 points
This function defines the strapping table.
The maximum number of points is 20.
Each subsequent value must be greater than the previous one.
The length and volume units can be changed later without affecting the settings in the
table. Calculations are done automatically in the instrument.
0
(i.e. no volume table)
2.1.7.3
DELETE TABLE
This function deletes the strapping table.

TESTS
2.2.1
TEST OUTPUT
Select 4 mA, 12mA, 20 mA, Other
This function allows the current output to be tested.
The output can be set to one of the listed values.
With a reference ammeter, the calibration of the current output can be verified.
2.3.0
SERVICE
Restricted access factory configuration menu. These parameters may be
accessed via Function 3.2 “Specialist PSW (password).

ACCESS RIGHTS
3.1
MAINTENANCE
PSW
Yes or No.
Enter 9-character code if “Yes”.
Disables the access lock on the configuration menu.
The password must contain exactly 9 characters.
E, R or U are used only. The password is displayed in a scrambled format.
It allows HYCONTROL to decode the password in case it was forgotten.
No
