4 MOUNTING
4.1 General
If the ND9200F is supplied with valve and actuator, the
tubes are mounted and the ND9200F adjusted in
accordance with the customer’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-ND9206FN
The controller is equipped with the Metso flush mounting
face, the old Neles mounting face and for connection
according to VDI/VDE 3845.
Shaft coupling alternatives for the controller for Metso
actuators are shown in Fig. 5.
For mounting parts for Metso actuators, see 12.3 - 12.8.
4.2 Mounting on EC and EJ actuators
See figure in Section 12.3.
❑
Mount the U-shaped coupling (47) to the shaft.
Apply thread-locking compound to the screws
(48) and tighten firmly.
❑
Remove the protective plastic plugs from pneu-
matic connections C2, S and C1. Mount the
metal plugs (53) to the unused controller con-
nections with sealant.
For EC (double acting) actuators, remove the
metal plugs (54, 2 pcs) from the connections at
the bottom of the controller. For EJ (single acting,
spring to close) and EJA (single acting, spring to
open) actuators, leave the metal plug (54) in the
C1 connection at the bottom of the controller and
remove the metal plug from the C2 connection at
the bottom.
❑
Mount the O-rings (38, 4 pcs.) into the air con-
nections in the bottom of the controller and the
mounting plate (64).
❑
Install the mounting plate (64) on the actuator as
shown in 12.3.
❑
Place the valve controller on top of the actuator
so that the pointer is located in the position
shown in Fig.5.
❑
Fasten the screws (4).
4.3 Mounting on Metso actuators with
VDI/VDE mounting face
See figures in Section 12.4 -12.6.
❑
Mount the H-shaped coupling (47) to the shaft.
Apply the thread-locking compound to the screw
(48) and tighten firmly.
❑
Remove the protective plastic plugs from pneu-
matic connections C2, S and C1. Leave the metal
plugs (54) in the unused connections at the bot-
tom of the controller.
❑
BJ and other single acting actuators: install 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 12.4. Secure the screw of the ear using e.g.
Loctite and tighten firmly.
❑
Attach the bracket (1) to the ND9200F.
❑
Attach the bracket (1) to the actuator. The shaft cou-
pling of the ND9200F must fit into the ear (2) so that the
pointer is located in the position shown in Fig.4.
NOTE:
The enclosure of ND9200F intelligent valve controller
meets the IP66 protection class according to EN 60529
in any position when the cable entry is plugged accord-
ing to IP66.
Based on good mounting practice, the recommended
mounting position is electrical connections placed
downwards. 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 war-
ranty is not valid.
