Operating instructions, data sheet, approvals and further information via the QR
code on the device or via www.kobold.com
The devices are only to be used, maintained and serviced by persons familiar
with these operating instructions and in accordance with local regulations
applying to Health & Safety and prevention of accidents.
When used in machines, the measuring unit should be used only when the
machines fulfil the EU-machine guidelines.
3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
Plug-On Display model: AUF-1.../AUF-3.../AUF-4...

4. Regulation Use
Any use of the Plug-On Display, model: AUF-..., which exceeds the
manufacturer’s specification, may invalidate its warranty. Therefore, any resulting
damage is not the responsibility of the manufacturer. The user assumes all risk
for such usage.
5. Operating Principle
The model AUF-... plug-on display is a universal local display suitable for use with
various transmitters. The transmitter must be fitted with an analogue output 4-20
mA and a connector in accordance with DIN 43 650. The plug-on display is
simply plugged in between the connector and socket; it is then ready for
operation. Scaling, the position of the decimal point, gate time and switch point
(optional) may be set with two keys. The menu steps are output to the LED
display field.
The Auf-4000 transforms the input pulses into a 4-20mA output signal.
6. Mechanical Connection
The plug-on display is simply plugged in between the connector and the socket; it
is then ready for operation. The mounting screw must be replaced with the longer
screw that is part of the delivery scope. The seals must be located between the
sensor/AUF and AUF/sensor.
The indicating unit can be rotated in 90° steps.
Beneath the LED-display a dimension-band can be mounted.

Auxiliary power (only AUF-1...)
The auxiliary power (typically 24 VDC) must be greater than the voltage drop
across the sensor, the voltage drop across the display (5 V) and any other
voltage losses (additional evaluation, cable losses).
Ub ≥ Us + (Ua) +5V (Us = voltage drop across sensor)
Switching output (only AUF-1001)
The operating voltage Ub at PIN 3 is connected through via a PNP-transistor
when reaching the switching threshold. The max. current load constitutes 60 mA.
