4.5.1
AUTO CAL
calibration function
During calibration process a blinking text "
CAL run
" will
be show on the display. If calibration ends successfully, a
text "
CALIBRATION SUCCESSFUL
" will be shown. Calibra-
tion can be cancelled with the
=
key, which will show a
text "
CALIBRATION CANCELLED
". If calibration fails, the
reason will be shown, eg. "
CALIBRATION START FAILED
",
"
POSITION SENSOR RANGE TOO SMALL
", "
CALIBRATION
TIMEOUT
" or "
CALIBRATION FAILED
". After calibration the
device will return to the main menu (measurement moni-
toring).
4.6
Testing,
TESt
Select between two tests Partial Stroke Test (
PARt
tst
) or Pneumatics test (
PNEU tst
).
To conclude press the
?
key when the desired
value is shown on the display.
4.6.1
Partial Stroke Test,
PARt tst
Partial stroke test can be run from here. Partial stroke test will
be run according to the stroke size (
MStr
) described in Sec-
tion 4.7. Advance parameters.
Select
PARt tst
from the menu by using
+
or
-
keys and press the
?
key.
Test can be cancelled by pressing

.
4.6.2
Pneumatics test,
PNEU tst
Pneumatics test can be run from here.
Select
PNEU tst
from the menu by using
+
or
-
keys and press the
?
key.
Test can be cancelled by pressing
=
.
WARNING:
Automatic calibration drives the valve against the
mechanical open and closed travel limits of the valve-
actuator assembly and a tuning procedure is perfor-
med. Make sure that these procedures can be safely
executed.
Fig. 19
Calibration selection
NOTE:
Valve position needs to be in the normal operating posi-
tion, supply pressure needs to be in valid range, no supply
pressure drop is allowed and any test cannot be active
when calibration is started.
Pneumatics test needs to be performed succesfully before
the calibration.
WARNING:
Partial Stroke Test moves the valve according to the
stroke size and speed parameters set. Make sure that
this procedure can be safely executed.
NOTE:
Valve position needs to be in the normal operating posi-
tion, supply pressure needs to be in valid range, no supply
pressure drop is allowed and any other test or calibration
cannot be active when testing is started.
NOTE:
When double acting actuator is used, DTM or other HART
user interface is needed to set 'Actuator Low Limit Pres-
sure' -parameter to negative value, e.g. -2.
NOTE:
Pneumatics test (Section 4.6.2.) will be run automatically
before the partial stroke test in some cases, e.g. when sup-
ply pressure has changed.
With the VG9000H_P version the pneumatics test will be
run always before the partial stroke test.
Pneumatics test timeout parameter is valid also in this
case.
NOTE:
Pneumatics test will check the pneumatics function of the
device by moving the spool valve only and not moving
the actuator or the valve.
NOTE:
Valve position needs to be in the normal operating posi-
tion, supply pressure needs to be in valid range and any
other test or calibration cannot be active when testing is
started.
NOTE:
Pneumatics test timeout parameter is 600 s. The value
cannot be changed.
NOTE:
Separate pneumatics test is not available in VG9000H_P
version. It will be run automatically always before the par-
tial stroke test.
