post in paper form against an applicable postage fee.
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 EC-machine guidelines.
3. Regulated Usage
The KOBOLD Plug-On Display is to be installed only in the specified applications.
Every usage, which exceeds the specifications, is considered to be non-specified.
Therefore, any resulting damage is not the responsibility of the manufacturer.
When installing, commissioning and operating these instruments, observe the
following: Any applicable national product safety standards (for example VDE
0100), the certificate of conformity specifications for plug-on displays with Ex
protection, and the relevant national standards for Ex service (for example: VDE
0165) are to be observed. Only competent personnel should work on the
instruments.
4. Operating Principle
The model AUF-2000 Plug-On Display is a universal local display suitable for use
with various transmitters. The transmitter must be fitted with an analogue output
and a connector in accordance with DIN 43 650. The plug-on display is simply
plugged in between connector and socket; it is then ready for operation. Upon
removal of the cover, scaling, the position of the decimal point and damping may
be set with two keys. The setup menu steps are displayed in the LED display
field.

forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
 Plug-On Display model: AUF-2000
 Mounting screw
 Units adhesive label
6. Mechanical Connection
The Plug-On Display is simply plugged in between the existing connector and
socket and is then ready for operation. The existing mounting screw must be
replaced with the longer screw which is part of the delivery. If desired, the display
can be rotated 90° in either direction.
7. Electrical Connection
Connect the plug-on display as shown in the wiring diagram.
