VEGA VEGADIF 55 4 … 20 mA_HART - Manual (Page 38)

1 P ressure for LRV is on the instrument
2 P ush "-" key at least for 3 s
3 D oes the LED on the electronics module light briefly?
Y es: existing pressure was accepted as LRV
N o: Existing pressure for LRV was not accepted, note the
adjustment limits
Set URV:
1 P ressure for URV is on the instrument
2 P ush "+" key at least for 3 s
3 D oes the LED on the electronics module light briefly?
Y es: existing pressure was accepted as URV
N
o: existing pressure for URV was not accepted, take note of the
adjustment limits
I f no local indication is connected, the following functions will be
possible via the three keys on the electronics module or outside on the
instrument:
l P
osition adjustment (zero point correction)
l S et the lower and upper pressure value and assign a level value to
the lower or upper level value
l I nstrument reset, see chart in chapter "Operating elements"
Information:
T
he adjustment must be unlocked, see chapter "Lock/Unlock adjust-
ment".
B y default, the instrument is set to mode Pressure. The mode can be
changed via the parameter "Measuring Mode", see chapter "Select
language and measuring mode".
I f "Level Mode" "Pressure Linearized" or "Height Linearized" or
" Calibration Mode" "dry"
are selected, the "-" and "+" keys are without
function.
T he existing pressure must be within the nominal pressure limits of the
sensor, see specifications on the "Type label".
S ee also "Quick setup menu" in chapter "Level measurement"
l D efault settings of the parameters in mode "Level":
-
LEVEL MODE = L inear
-
CALIBRATION MODE = wet
-
LIN. MEASURAND = %
-
EMPTY CALIB. = 0 %
-
FULL CALIB. = 100 %
Carry out position adjustment:
1 P ressure on the instrument
2 P
ush "E" key at least for 3 s
