TRANSPORTATION, RECEPTION AND
STORAGE
The valve controller is a sophisticated instrument, handle it
with care.
Check the controller for any damage that may have
occurred during transportation.
Store the uninstalled controller preferably indoors,
keep it away from rain and dust.
Do not unpack the device until installing it.
Do not drop or knock the controller.
Keep the flow ports and cable glands plugged until
installing.
Follow instructions elsewhere in this manual.

MOUNTING
4.1
General
If the ND is supplied with valve and actuator, the tubes are
mounted and the ND adjusted in accordance with the cus-
tomer’s specifications. If the controller is ordered separately,
the mounting parts for the assembly must be ordered at
the same time.
Sample order: (B1CU13)-Z-ND9_06HN
Shaft coupling alternatives for the controller for Metso
actuators are shown in Fig. 6.
4.2
For mounting parts for Metso actuators,
see 12.5–12.10.Mounting on Metso
actuators
with VDI/VDE mounting face
See figures in Section 12.6–12.7.
ND9100, ND9400, ND7100
Mount the H-shaped coupling (47) to the shaft.
Apply the thread-locking compound to the screw
(48) and tighten firmly.
Remove all protective plastic plugs from the pneu-
matic connections (5 pcs.). Mount the metal plugs
(54) with sealant to the unused controller connec-
tions at the bottom of the controller.
BJ and other single acting actuators:
mount a
metal plug (53) with sealant to the C1 connection.
Set the direction arrow of the actuator in the direc-
tion of the valve closure member and attach the ear
(2) to the indicator cover in the position shown in
Section 12.6-12.7. Secure the screw of the ear using
e.g. Loctite and tighten firmly.
Attach the bracket (1) to the ND.
Attach the bracket (1) to the actuator. The shaft cou-
pling of the ND must fit into the ear (2) so that the
pointer of the shaft washer (16) is located in the posi-
tion shown in Fig. 5.
Intrinsic Safety (Ex i) WARNING (ND9100, ND9200,
ND9300 and ND7100):
Ensure that the complete installation and wiring is
intrinsically safe before operating the device!
The equipment must be connected via a certified Zener
barrier placed outside the hazardous area.
Ex WARNING
(ND9200, ND7200)
:
Electrostatic charge hazard!
The windows and identification plate are non-conductive.
Clean with a damp cloth only!
Ex WARNING
(ND9100, ND7100)
:
For use in the presence of combustible dust.
Device shall not be subjected to a prolific charge gen-
erating mechanism.
Ex WARNING (ND9000, ND7000):
Accumulation of dust shall be avoided!
Ex d WARNING (ND9200, ND7200, ND9300):
Use a cable gland and blind plug with suitable Ex d
certification.
For ambient temperature over 70 °C / 158 °F use a heat
resistant cable and cable gland suitable for at least
90 °C / 194 °F.
Ex n WARNING (ND9100, ND9200, ND9300 and ND7100):
At an ambient temperature ≥
+70 °C / 158 °F, the tem-
perature rating of selected connection cable shall be
in accordance with the maximum ambient tempera-
ture range.
Selected cable gland shall not invalidate the type of
protection.
Ex i WARNING (ND9100, ND9200, ND9300 and ND7100):
At an ambient temperature ≥
+70 °C / 158 °F, the tem-
perature rating of selected connection cable shall be
in accordance with the maximum ambient tempera-
ture range.
Ex NOTE:
Follow the standards EN/IEC 60079-14 when installing the
equipment and and EN/IEC 60079-25 when connecting
Ex i interfaces.
NOTE:
The enclosure of ND9000 and ND7000 intelligent valve
controller meets the IP66 protection class according to
EN 60529 in any position when the cable entry is plugged
according to IP66.
Based on good mounting practice, the recommended
mounting position is electrical connections placed down-
wards. This recommendation is shown in our mounting
position coding for control valves.
If these requirements are not fulfilled, and the cable gland
is leaking and the leakage is damaging valve controller or
other electrical instrumentation, our warranty is not valid.
NOTE:
Make sure the mounting of the device and the valve
assembly is suitable for the weight of the assembly.
