1.4 Intended use
The layer thickness sensor KVF-103-PF (referred to as "sensor" in the following sections) is a
suspended sensor for detecting the oil layer thickness in oil/petrol separators.
The KVF-103-PF must always be connected to a certified intrinsically safe warning device of
the type NVOA-130, NVO-4A30, NVO5-15 or NVO5-11 (see product program).

1.5 Delivery, Transport and Storage
Check the packaging and contents for damage. In the event of damage, notify the postal
service or express agent and inform the supplier.
Check the scope of supply for completeness and correctness using the order and delivery
papers.
Keep the original packaging.
The device should always be stored or transported in the original packaging.
Always store the device in a dry and clean environment. Observe the permissible storage
temperature (see data sheet).
1.6 Installation and Commissioning
1.6.1 Installation of the sensor
The sensor may be installed in potentially explosive zone 0 in accordance with Directive
94/9/EC (ATEX). The sensor must not be installed in places with potentially aggressive vapors.
The sensor and warning device must be free of voltage during installation and maintenance.
The warning device must only be connected to the supply voltage after complete mounting and
connection of the sensors.
The cable and the identification plate attached to it are elements of the product. The cable must
not be shortened to such an extent that the identification plate is removed. The identification
plate must not be removed.
EN
The sensor has IP68 protection and is weather- and oil-resistant. It can therefore be installed in
oil/petrol separators.
When installing the device in oil/petrol separators, observe the permissible ambient
temperature in the range from -20 °C...60°C (253 K ... 333 K).
1.6.2 Installation in connection with intrinsically safe circuits
Installation of the intrinsically safe power circuits of the devices is permitted in potentially
explosive zones, whereby, in particular, safe separation from all non-intrinsically safe power
circuits must be guaranteed.
The intrinsically safe current circuits must be installed according to valid setup regulations.
For the interconnection of the intrinsically safe field devices and the intrinsically safe power
circuits of the associated devices, the respective maximum values of the field device and the
associated device with regard to explosion protection must be observed (proof of intrinsic
safety). EN 60079-14/IEC 60079-14 must be observed.

1.6.3 Sensor cable
Sensor cables must not be installed in cable or conductor bundles together with other current
circuits. Avoid installing sensor cables parallel to other cables that may transmit interfering
EN

1.7.1 Caution - emulsions
1.8 Maintenance
signals, which impair the sensor signal and thus the alarm function. The sensor itself must not
be grounded.
If you extend the sensor cable, observe the applicable ATEX specifications with regard to color,
quality and constancy. Use an unscreened cable with a conductor size of 1 mm².
An oil/petrol separator is a device for separating oil from water. Situations may arise in which
the oil can not be separated because an emulsion has formed. An emulsion is a relatively
stable mixture of oil and water. Sensors can not detect oil if emulsions with a high water content
have formed. Always contact the oil/petrol separator manufacturer if there is any doubt as to
whether the oil has been separated from the water before the liquid is drained to the sewage
system.
For operation of oil/petrol separators, there may be standards, directives or laws that define
regular system or sensor tests. Check the operation of the sensor at least twice a year and
more frequently in the event of unfavorable environmental conditions.
When the oil/petrol separator is being emptied (disposal), the sensor must always be washed
and dried. The sensor must not be cleaned with caustic fluids. A badly contaminated sensor
can trip a wrong alarm or, in certain circumstances, fail to trip an alarm.
1.9 Repair
The devices may not be repaired, changed or manipulated. If there is a defect, the product
must always be replaced with an original part.
1.10 Disposal
Disposal of devices and their packaging material must be performed in compliance with the
applicable laws and guidelines of the corresponding country.
The devices do not contain batteries which need to be disposed of separately from the
products.

2.2 Design and dimensions
The sensor has an integrated electronic circuit which, via an oscillator circuit, emits a weak HF
signal that changes depending on whether the sensor element is surrounded by water or by
oil/air. The sensor is capable of distinguishing between air and water, and between water and
oil, but not between air and oil.

Installation

3.1 Mounting in oil/petrol separators
EN
Read the chapter on Safety and, in particular, the section on Installation and commissioning
(see chapter 1.6.1)before connecting the sensor. Do not remove the identification plate.
Warning!
Risk of short circuit
Injuries and damage to the device are possible when working with live parts.
• Before working on the device, always disconnect the supply voltage.
• Connect the device to the supply voltage only after completion of the work.
During installation, observe the instructions of the oil/petrol separator manufacturer. Always
ensure that the sensor suspension device remains constantly at the correct height. If possible,
ensure that the suspension device is mounted in a location that can be reached from the
separator access shaft so that it is possible to raise the sensor during separator emptying
(disposal) or maintenance of the oil/petrol separator.
An exact height adjustment is made with the mounting set. For securing in a concrete
container, use mounting set NVO5-B supplied with the equipment. For containers, tanks or
separators made of other materials, e. g. plastic or metal, use other appropriate means of
mounting (screws and dowels).
When the liquid level is correct, the sensor must be submerged a few centimeters into the
liquid. Exactly how far it is submerged depends on the type of the oil/petrol separator, the
design and the capacitance. The sensor must be suspended above the liquid. The switch point
(see chapter 2.2, dimension drawing, position 2) of the sensor is located at the tip of the sensor.
This means that the tip of the sensor must be installed at the height specified as the maximum
layer thickness.

The sensor is a sensitive component. Therefore always observe the following safety
information during emptying (disposal):
Caution!
Malfunction or damage through mechanical stress of the sensor.
In case of nonobservance, the safety and operation of the sensor or the entire alarm system is
not guaranteed.
• Before emptying (disposal) the oil/petrol separator, remove the sensor from the container.
• Protect the sensor against impacts, knocks and unnecessary tensile forces in the cable.
• Insert the sensor in the oil/petrol separator only after it has been filled.
