Recycling and disposal
Most valve controller parts can be recycled if sorted
according to material.
Most parts have material marking. A material list is sup-
plied with the valve controller. In addition, separate recy-
cling and disposal instructions are available from the
manufacturer.
A valve controller may also be returned to the manufac-
turer for recycling and disposal. There will be a charge
for this.

MOUNTING
3.1
General
If the ND9200H is supplied with valve and actuator, the
tubes are mounted and the ND9200H 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-ND9206HN
The controller is equipped with the Metso Automation
flush mounting face, the old Neles mounting face and for
connection according to VDI/VDE 3845.
Shaft coupling alternatives for the controller for Metso
Automation actuators are shown in Fig. 5.
For mounting parts for Metso Automation actuators, see
10.2 - 10.8.
3.2
Mounting on EC and EJ actuators
For EC actuators see figure in Section10.2.
For EJ actuators see figure in Section10.3.
❑
Mount the U-shaped coupling (47) to the shaft.
Apply thread-locking compound to the screws
(48) and tighten firmly.
CAUTION:
Do not exceed the permitted values!
Exceeding the permitted values marked on the valve
controller may cause damage to the controller and to
equipment attached to the controller and could lead
to uncontrolled pressure release in the worst case.
Damage to the equipment and personal injury may
result.
CAUTION:
Do not remove or dismantle a pressurized controller!
Removing or dismantling a pressurized prestage or
spool valve of an ND9200H leads to uncontrolled
pressure release. Always shut off the supply air and
release the pressure from the pipelines and equip-
ment before removing or dismantling the controller.
Otherwise personal injury and damage to equipment
may result
.
WARNING:
During automatic or manual calibration and tuning
the valve operates between open and closed posi-
tions. Make sure that the operation does not
endanger people or processes!
Ex d WARNING:
Do not open the device when energized!
Explosion protection is lost.
Electromagnetic immunity is reduced, valve may
stroke.
Ex d WARNING:
Use a cable gland 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.
NOTE:
Avoid earthing a welding machine in close proximity to
an ND9200H valve controller.
Damage to the equipment may result.
Ex d NOTE:
Follow the installation guidelines in EC-EN 60079-10
when mounting the equipment.
NOTE:
The enclosure of ND9200H 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.
