2. Note
Please read these operating instructions before unpacking and putting the unit
into operation. Follow the instructions precisely as described herein.
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 EWG-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:
•user's manual (this sheet)
•warnings
•96x48 display model: A2X90-VM
•two fixing clamps
•removable 12 pole terminal blocks (into the unit)
4. Regulation Use
Any use of the 4…20 mA indicator model: A2X90-VM, 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 A2X90-VM 96x48 loop powered display is a universal local display
suitable for use with various transmitters. The transmitter must be fitted with an
analogue output and a terminal blocks.
The display is user programmable. Scaling, the position of the decimal point,
gate time and switch point may be set with two keys. The menu steps are output
to the LED display field.
6. Mechanical Data
The instrument is setted up for panel mounting.
It is fixed in place with the two clamps provided.
The maximum permitted panel thickness is 4mm.
Make all electrical connections with power supply off.
Take care to ensure electrical connections are correct.
Insert the clamps into the button-holes in the right and left sides of the
instrument and put them in tension turning the pin with a screw -driver (slot or
cross, 4 mm).
Make all electrical connections are correct as showed in the schemas below.

Auxiliary power
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 = other voltage losses)
Switching output
The operating voltage Ub at PIN 1is connected through via a PNP-transistor
when reaching the switching threshold. The max. current load constitutes 60
mA.
