1.5 Delivery, Transport and Storage
Check the packaging and contents for damage.
Check if you have received every item and if the items received are the ones you
ordered.
Keep the original packaging. Always store and transport the device in the original
packaging.
Always store the device in a clean and dry environment. The permitted storage
temperature (see data sheet) must be considered.
1.6 Installation and Commissioning
1.6.1 Installation of the Sensor
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 sensor has IP68 protection and is weather- and oil/fat-resistant. It can
therefore be installed in grease interceptors.
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 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 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 specifications with regard
to color, quality and durability. Use unshielded cables.
1.7 Maintenance
For operation of grease interceptors, 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 grease interceptor 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.

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.

2.1 Function
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 fat.
The sensor is mounted suspended and immersed in liquid.
The sensor can distinguish between water and floating fat, oil and grease (FOG).

3 Installation
3.1 Mounting of the Sensors
Read the chapter on Safety and, in particular, the section on Installation and
Commissioning (see chapter 1.6) before mounting the sensor. Do not remove the
identification plate.
During installation, read the instructions provided by the grease interceptor
manufacturer. Ensure that the suspension mechanism keeps the sensor
permanently at the correct height. Where possible, secure the device in a position
where it can be reached from the manhole opening so that it can be removed
when emptying (disposal) or carrying out maintenance work on the grease
interceptor.
The precise height of the sensor depends on how it is mounted. When mounting
in a concrete tank, for example, use the NVO5-B mounting set (see figure below).
For containers, tanks or separators made from other materials, such as plastic or
metal, use the appropriate alternative mounting options (screws and dowels).
Figure 3.1 Mounting using cable connector and mounting set
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.

3.2 Mounting the KVF-F Fat Level Sensor
The sensor must be immersed a few centimeters when the liquid is at its normal
level (water zero line).
The exact immersion depth depends on
■the type of grease interceptor,
■its design,
■its capacity
■and the height of the maximum fat layer thickness.
The sensor must always be immersed in the liquid. The switching point of the
sensor is located between the insulated connecting piece and the top metal
section.

3.3 Connection of the Sensor
Read the chapter on Safety and, in particular, the section on Installation and
Commissioning (see chapter 1.6) before connecting the sensor.
Take care not to reverse the polarity when connecting the sensor cable. The loop
resistance of the extension cable should not exceed 20 Ωfor the sensors.
For extending the sensor cable, use cable connector LAL-SK2.
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.
Note!
Avoid installing sensor cables parallel to other cables that may transmit interfering
signals, which impair the sensor signal and thus the alarm function. Use
unshielded 2-wire cable for each sensor.
To ensure perfect operation of the warning device, do not exceed:
■the max. cable length of 190 m with a cross-section of 0.75 mm2.
■the max. cable length of 250 m with a cross-section of 1 mm2.
Note!
Further information on connection of the sensors to the warning device is
available in the manual of the warning device NVD-111.

4.1 Emptying (Disposal) of the Container
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 grease interceptor, remove the sensor from
the container.
■Protect the sensor against impacts, knocks and unnecessary tensile forces in
the cable.
■Insert the sensor in the grease interceptor only after it has been filled.

5 Maintenance and Repair
5.1 Function Testing
Test frequency
The sensor is maintenance-free. However, to guarantee perfect operation of the
complete alarm system check the operation of the sensor at least once a year, or
more frequently in the event of unfavorable environmental conditions.
Checking the normal status
1. Switch DIP switch 1 to position OFF.
2. Remove the sensor from the grease interceptor.
3. Wash and dry the sensor.
4. Hold the sensor in your hand (no gloves). Only touch the upper and lower
metal section ( see Figure 2.1 on page 7) or
5. Immerse the sensor in water.
The green "SYSTEM OK" LED on the warning device flashes or lights up.
Checking the alarm situation
1. Switch DIP switch 1 to position OFF.
2. Suspend the fat level sensor freely in air.
The red "FAT LAYER ALARM" LED lights and, if applicable, an acoustic
signal sounds.
Note!
Further information on connection of the sensors to the warning device is
available in the manual of the warning device NVD-111.

1.5 Lieferung, Transport und Lagerung
Überprüfen Sie Verpackung und Inhalt auf Beschädigung.
Überprüfen Sie den Lieferumfang auf Vollständigkeit und Richtigkeit.
Bewahren sie die Originalverpackung auf. Das Gerät sollte immer in der
Originalverpackung eingelagert oder transportiert werden.
Lagern sie das Gerät immer in trockener und sauberer Umgebung. Beachten sie
die zulässige Lagertemperatur (siehe Datenblatt).
1.6 Installation und Inbetriebnahme
1.6.1 Installation des Sensors
Der Sensor und die Warnanlage müssen bei Installation und Wartung
spannungsfrei sein. Erst nach kompletter Montage und Anschluss der Sensoren
darf die Warnanlage an die Versorgungsspannung angeschlossen werden.
Der Sensor ist in Schutzart IP68 ausgeführt und wetter- und öl-/fettbeständig. Er
kann deshalb in Fettabscheideranlagen installiert werden.
Beachten Sie bei der Installation des Sensors in Fettabscheideranlagen die
zulässige Umgebungstemperatur im Bereich von -20 °C...60°C
(253 K ... 333 K).
1.6.2 Sensorkabel
Sensorkabel dürfen nicht in Kabel- oder Leiterbündeln gemeinsam mit anderen
Stromkreisen verlegt werden. Vermeiden Sie, das Sensorkabel parallel mit
anderen Kabeln zu verlegen, von denen Störsignale ausgehen können, die das
Sensorsignal und damit die Alarmfunktion beeinträchtigen. Der Sensor selbst
darf nicht geerdet werden.
Wenn Sie das Sensorkabel verlängern, beachten Sie die geltenden Vorschriften
bezgl. Farbe, Qualität, Beständigkeit. Verwenden Sie ungeschirmtes Kabel.
1.7 Wartung
Für den Betrieb von Fettabscheideranlagen können Normen, Richtlinien oder
Gesetze vorliegen, die Forderungen nach regelmäßigen Systemprüfungen oder
Sensorprüfungen festlegen. Prüfen Sie die Funktion des Sensors mindestens
zweimal jährlich, unter erschwerten Umgebungsbedingungen öfter.
Der Sensor ist beim Entleeren (Entsorgen) der Fettabscheideranlage immer zu
waschen und zu trocknen. Der Sensor darf dabei nicht mit ätzenden Flüssigkeiten
gereinigt werden. Ein stark verschmutzter Sensor kann Fehlalarm auslösen oder
unter Umständen keinen Alarm auslösen.
