2 Instructions for using the measuring amplifier
Notice:
The parameterizations, further information concerning the scaling as well as the customized
analogue output can be found on the additional sheet “Device-Configuration”.
Since this amplifier is a highly sensitive measurement product, it must be used for its intended use as
well as the described operation conditions only. Initial start-up and changes in setup and settings must
be done by qualified personnel only. To prevent interventions / modifications made by unauthorized
personnel, suitable measures must be taken. Both function and calibration buy be checked regularly.
The amplifier is contained in a plastic housing (IP20) designed for DIN top hat rail montage. The
electrical connections are made via screw-clamps and the sensor may be connected in 4- or 6-wire
technology. The amplifier must be operated with a separate power source used for measurement
devices only.
To avoid possible potential equalization currents over the shield of the cable to the following evaluation
unit, this shield should be connected via a suitable capacitor (10nF / 200V).
All connection cables and the amplifier itself must not be installed in proximity to disturbance
(interference / noise) emitting devices or cables.
Overall the shield connections must be done properly to EMC-standards (as short as possible with large
wire cross-section) and connected to a central point (star grounding). In order to not increase the
interference sensitivity of the amplifier, all cables should be kept as short as possible and should not be
extended. Possible cable-bound interferences must be blocked very near the cable ends (evaluation
unit) by suitable measures.
Notice:
Changes of the amplifier of any kind demand for the explicit approval of Althen Mess- &
Sensortechnik GmbH. Changes of any kind done without that approval exclude all possible warranty
and/or liability of Althen Mess- & Sensortechnik GmbH.
