Technical Information / Instruction manual

Introduction
The Capanivo series CN 7000 is a capacitance switch for:
• Level detection of liquids, solids (powder and granules), slurries and foam.
• Interface detection (for example, oil / water or foam / liquid)
It works in all types of vessels, pipes and silos within a wide range of appliations like:
• Food, brewery, dairy, beverage and pharmaceuticals
• Chemical and petrochemical
• Water and waste water
• Machine building industry
It can also be used for leckage detection in double walled vessels, tanks and silos or in
moldings and collecting ponds.
Applications
Measurement
principle
The Capanivo series CN 7000 detects the capacitance around its probe. Due to the active
shield technology it has an increased insensitivity to material buildup on the probe.
Features
Process • Measurement independent from inuence of the vessel wall
• Factory provided precalibration allows measurement of most applications without
sensitivity setting on site
• Active shield electrode for compensation of material buildup
• Potted construction protects from shock, vibration, humidity, condensation
• Dielectric constant of 1.5 or more
• Process temperature up to 125°C
• Approvals CE, FM, FMc, WHG
Electronics • IO-Link, IEC 61131-9 SDCI standard
• PNP, NPN or Push-Pull output (congurable)
• Terminal or M12 plug
• Sensitivity setting by IO-Link or by potentiometer (congurable)
Mechanics • Corrosion resistant construction with enclosure made of thermoplastic polyester,
wetted parts made of PPS, PVDF, PEEK and 316L stainless steel
• Compact probe lenght
• Pipe extension (max. 4m), optional sliding sleeve allows to change the switch point
easily during operation of the device
• Various process connections: threaded (including G½“ hygienic), anged (screwed)
or Tri-clamp

Mechanical installation
General Safety Instructions
Process pressure Improper installation may result in loss of process pressure.
Observe possible pressure limitation from the used ange type or in case of use of the
sliding sleeve (CN 7130).
Chemical resistance
against the medium
Materials of construction are chosen based on their chemical compatibility (or inertness) for
general purposes. For exposure to specic environments, check with chemical compatibility
charts before installing.
Fastening of the
threaded process
connection
Mounting torque for the thread may not exceed 40 Nm (metal thread)/ 20 Nm (plastic
thread). Use a open-end wrench. Do not fasten by turning the housing, for this will destroy
the unit.
EHEDG approval/
Food grade material
The materials are available for the use under nornal and predictable applications (according
to directive 1935/2004 Art.3). Other conditions can inuence the safety.
General Mounting instructions
At the end of the
pipe before the
probe
Midway along
the pipe
At the process
connection or
ange
Handling
precautions
To prevent damage of the pipe extension, all CN 7130 units with a pipe longer than 2 m (6.5
ft), must be suppported at these three points when lifting from a horizontal position
Sliding sleeve Tighten both straining screws with 15 Nm to obtain
resistance against pressure
Direction of the
cable glands
(enclosure Ø65mm)
When the unit is mounted from the side, ensure, that the cable glands face downwards and
are closed to avoid water penetration into the housing.
The enclosure can be rotated against the process connection after mounting.
Sealing Ensure proper seal of the process connection thread in case of process pressure.
Hygienic process
connection
Observe that the correct "On site process connection" is present, see page 8.

Electrical installation
Handling In the case of inexpert handling or handling malpractice the electric safety of the device
cannot be guaranteed.
Installation
regulations
The local regulations or VDE 0100 (Regulations of German Electro technical Engineers) must
be observed.
Power supply switch A power-supply-disconnecting switch must be provided and marked near the device.
Wiring diagram The electrical connections have to be made according to the wiring diagram.
Supply voltage Compare the supply voltage applied with the specications given on the name plate before
switching the device on.
The unit must be supplied from a SELV source providing electrical isolation between the
input and output, in order to meet the applicable safety requirements of IEC 61010-1.
Observe reduced supply voltage ratings in wet locations. A wet location is a location where
water or other conductive liquid may be present and is likely to increase the risk of electric
shock.
Cable gland
and
Field wiring cables
With use of terminal block and cable gland:
The screwed cable gland must have following specications:
• Ingress protection IP68
• Temperature range from -40°C to 10 K above max. ambient temperature
• UL or VDE certied (depending on the country where the unit is installed)
• Pull relief
Make sure that the screwed cable gland safely seals the cable and that it is tight (danger of
water intrusion).
The eld wiring cables must have following specications:
• The diameter has to match to the clamping range of the used cable gland.
• The cross section has to match with the clamping range of the connection terminals and
consider the max. current.
• The temperature rating must be at least 10 K above max. ambient temperature.
Cut the eld wiring cables to appropriate length to t properly into the housing.
M12 mating plug
and
Field wiring cables
With use of M12 plug:
The mating plug must must have following specications
• M12x1 according to IEC 61076-2-101, female, 4-pole, coding A-standard
• Ingress protection IP68
• Temperature range from -40°C to 10 K above max. ambient temperature
The eld wiring cables must have following specications:
• The diameter and cross section has to match to the specication of the mating plug.
• The temperature rating must be at least 10 K above max. ambient temperature.
• Install the eld wiring cables according to the instructions of the mating plug
Signal output contact
protection
Provide protection for signal output to protect the device against spikes with inductive loads
(e.g. when connecting external relays).
Protection against
static charging
The unit must be earthed in any case to avoid static charging of the unit, especially on
applications with pneumatic conveying. Functional earthing is satisfactory to protect against
static charging, see page 21.
