Recycling and disposal

Most valve controller parts can be recycled if sorted accord-
ing to material.
Most parts have material marking. A material list is supplied
with the valve controller. In addition, separate recycling and
disposal instructions are available from the manufacturer.
A valve controller may also be returned to the manufacturer
for recycling and disposal. There will be a charge for this.

Safety precautions

NOTE (ND9000, ND7000):
Avoid earthing a welding machine in close proximity to an
ND valve controller.
Damage to the equipment may result.
(ND9000, ND7000)
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.
(ND9000, ND7000)
CAUTION
Do not remove or dismantle a pressurized controller!
Removing or dismantling a pressurized prestage or
spool valve of an ND leads to uncontrolled pressure
release. Always shut off the supply air and release the
pressure from the pipelines and equipment before remov-
ing or dismantling the controller. Otherwise personal
injury and damage to equipment may result.
(ND9000, ND7000)
WARNING
During automatic or manual calibration the valve
operates between open and closed positions. Make
sure that the operation does not endanger people or
processes!
WARNING (ND9000, ND7000):
Do not operate the device with electronics cover (39)
removed!
Electromagnetic immunity is reduced, valve may stroke.
Explosion protection may be impaired.
Ex d WARNING (ND9200, ND7200, ND9300):
Do not open the device when energized!
Explosion protection is lost.
ELECTRICAL SAFETY WARNING (ND9200, ND7200,
ND9300):
Use fuses for limit switch installations with
50 V AC / 75 V DC or higher.
Ex WARNING (ND9100, ND7100):
Electrostatic charge hazard!
The cover is non-conductive. Clean with a damp cloth
only!
Spark hazard!
Protect the aluminium housing from impacts and friction!
Ex WARNING (ND9100, ND9200, ND9300 and ND7100):
For use in the presence of combustible dust.
Ignition protection relies on the enclosure. Protect the
cover of the valve controller from impacts. When tempera-
ture is higher than 70 °C / 158 °F the temperature rating of
the cable shall be higher than the ambient temperature.
(ND9200, ND7200, ND9300)
Ex WARNING
The locking screw (part 107) of the cover is essential to
explosion protection.
The cover has to be locked in place for Ex d protection.
The screw grounds the cover to the housing.
