NDX VALVE CONTROLLER
Rotary mounting is designed according to VDI/VDE 3845
interface.
NOTE
The enclosure of NDX meets the IP66 pro
tection class according to EN 60529. Cable
entry needs to be plugged according to IP66
and it is not allowed to mount NDX in a po
sition where the cable entry is pointing up
wards. Based on good mounting practice, the
recommended mounting position is electrical
connections placed downwards. This recom
mendation 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 dam
aging NDX, our warranty is not valid.

Installation to Neles B-series actuators -
MAGNET MOUNTING
•
Mounting set includes mechanical position
indicator. It can be used if there is no position
indicator in the actuator.
•
Place position indicator plate to the correct position
so that it correspond to the valve position.
•
Lock position indicator plate with screw driver so
that it can’t turn by bending locking tabs.
•
Mount magnet to the actuator
There shall be use thread locking in magnet assembly to
prevent magnet loosening under heavy vibration. Thread
locking should be low or medium strength, e.g. Loctite 243.

Magnet will be tightened as tight as 4 Nm. From the oper
ation point of view magnet can be in any position so there
is no adjustment needed.

Installation to Neles B-series actuators -
BRACKET MOUNTING
For Neles BJ actuators there are few different mount
ing brackets, depending on actuator size. This example
shows NDX mounting to Neles BJ6 actuator. For other sizes
bracket types vary a little, but main steps are the same.
When mounting NDX to the Neles actuators, there is no
mechanical adjustment needed.
