1.3 Declaration of Conformity
All products were developed and manufactured under observance of the
applicable European standards and guidelines.
The product manufacturer, Pepperl+Fuchs GmbH, 68307 Mannheim, has a
certified quality assurance system that conforms to ISO 9001.
1.4 Intended Use
The warning device is a compact alarm system for monitoring one or two sensors
in grease interceptors.
The warning devices must only be installed in a suitable control cabinet or
NVO5-KV installation housing.
The warning device was designed for:
nthe monitoring of the fat layer thickness, i. e. an alarm if a certain limit of
maximum receptacle capacity of fat has been reached.
nthe monitoring of the overflow of liquid, e. g. in the event of a blocked drain
Note!
This symbol brings important information to your attention.
Note!
A Declaration of Conformity can be requested from the manufacturer.

Only the following sensors must be connected to the warning device:
1.4.1 Designation
1.5 Maintenance
The device must not be cleaned with caustic fluids.
The devices are maintenance-free. However, to guarantee perfect operation of
the complete alarm system, check the operation, including all sensors, at least
once a year.
1.6 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.
1.7 Installation and Commissioning
1.7.1 Installation of the warning device
The device must only be installed outside potentially explosive zones. The
device must not be installed in places with potentially aggressive vapors.
The device must be free of voltage during installation and maintenance. The
warning system must only be connected to the supply voltage after complete
mounting and connection of the sensors.
The identification plate must not be removed.

1.8 Operation
1.8.1 Availability of Emulsion
Grease interceptors are plants which can separate fat from water. It may occur
that fat is not separated due to the emulsion that has formed. An emulsion is a
more or less stable mixture of fat and water. If the water content in the fat is too
high, the sensor does not detect any fat.
1.9 Repair
The devices must not be repaired, changed or manipulated. If there is a defect,
the product must always be replaced with an original device.
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.

2.1 Function
The warning device monitors the status of
na fat level sensor or
nan overflow sensor or
nthe combination of an overflow sensor and a fat level sensor
in a grease interceptor.
LEDs at the device indicate alarm, sensor fault and system and sensor status. In
the event of an alarm, an additional acoustic signal sounds.
The fat in the grease interceptor can be of various compositions. The following
conditions are possible:
nThe fat is liquid. Such fat is found in, e. g., the manufacture and storage of
vegetable fats. This fat forms a liquid fat layer which clearly separates from
water. For this composition of fat, please use fat level sensor KVF-F for
detecting the fat layer thickness.
nThe fat is hard. Such fat is found in, e. g., waste water from sinks or
dishwashers and in floor drains in large kitchens or catering
establishments. This fat consists of a mixture of animal and vegetable fats.
It typically forms an aqueous emulsion with small lumps of fat or a
hardened layer of fat. For this composition of fat, please use fat level
sensor FAU-104 for detecting the fat layer thickness.
