Extra pneumatics instrumentation,
EXTI
In order to optimise the control performance the device
needs to be informed about the extra pneumatics instru-
mentation, if any.
After selecting
EXTI
on the display, press the
?
key
to enter the edit state and
EXTI
starts to blink.
Select between the following values:
non
= no external instrumentation
bo1
= booster type 1
bo2
= booster type 2
bo3
= booster type 3
qE1
= quick exhaust type 1
qE2
= quick exhaust type 2
qE3
= quick exhaust type 3
co1
= combination type 1
co2
= combination type 2
co3
= combination type 3
Use the
+
and
-
keys to change the value.
To conclude press the
?
key when the desired
value is shown on the display.
NOTE:
If nothing else is defined, please select type 1 in any
class.
Select parameters as follows:
4.4.5
Actuator size,
ACTS
This parameter defines the actuator size.
Look at e.g. the type code on the machine plate in
the Neles B1-series actuators to check the size. If 3rd
party actuator is used, please check the actuator
stroke volume.
After selecting
ACTS
on the display, press the
?
key
to enter the edit state and
ACTS
starts to blink.
Select between the following values:
S 1
= Neles B1J8 actuator
(or stroke volume <1 dm
3
/ <61 in
3
)
S 3
= B1J10 (1–3 dm
3
/ 61–183 in
3
)
S10
= B1J12-16 (3–10 dm
3
/ 183–610 in
3
)
S30
= B1J20–25 (10–30 dm
3
/ 610–1831 in
3
)
L30
= B1C40–, B1J32– (>30 dm
3
/ >1831 in
3
)
Use the
+
and
-
keys to change the value.
To conclude press the
?
key when the desired
value is shown on the display.
4.4.6
Spool type,
STYP
This parameter defines the spool type and size in VG9000H.
Look at the machine plate in the device to check the
typecode.
After selecting
STYP
on the display, press the
?
key
to enter the edit state and
STYP
starts to blink.

Volume booster (VB)
Booster type 1 (

)
Quick exhaust (QEV)
Quick exhaust 1 (

Combination of VB and QEV
Combination type 1 (

NOTE:
Bypass valve is mandatory with volume boosters and QEV.
Contact Metso for separate instrumentation diagrams and
instructions.
NOTE:
When QEV or volume booster is used, VG with standard
spool valve (VG_15_) is required.
CAUTION:
It is important to select the correct actuator size
because this parameter is used in device control.
Erroneous value may cause instability.
