1. General
If you have any queries regarding technical details or the suitability of the unit for your application,
please contact our
technical sales department . The AS 1000 is individually calibrated on
computer-controlled test rigs and subjected to a final test. In this way we can guarantee that the
unit is fault-free on despatch and conforms to the given specifications.
However, if there is a cause for complaint, please return the unit to
HYDAC Service outlining the
fault. Interference by anybody other than HYDAC personnel will invalidate all warranty claims.
2. Safety instructions
The Aqua Sensor AS 1000 presents no safety concerns when installed and operated in
accordance with this user manual. However, in order to avoid any risk to the operator or any
damage due to incorrect handling of the unit, please adhere strictly to the following safety
instructions:
• Before commissioning, please read the operating instructions. Ensure that the unit is suitable for
your application.
• During transportation, extra care must be taken to protect the unit from vibration and shock.
• The AS 1000 must not be put into service if any known defects, either electrical or mechanical,
are apparent.
• The unit must be installed exactly according to the instructions.
• Read the information on the type code label.
• Fault investigation and repairs must only be carried out by HYDAC Service.
• All relevant and generally recognised safety requirements must be adhered to.
• If the unit is not handled correctly, or if the operating instructions and specifications are not
adhered to, damage to the product or to personal injury may result.
3. Installation
The sensor can be installed directly in the hydraulic system via the threaded connection. The
recommended mounting position for hydraulic applications is vertical with the mechanical threaded
connection pointing upwards. When fitting, ensure that the sensor is completely submerged in the
fluid and that the fluid can circulate freely around the sensor. It is important, therefore, when tank-
mounting, to install the sensor in a position where there is guaranteed turbulence.
The electrical connection must be carried out by a qualified electrician according to the relevant
regulations of the country concerned (VDE 0100 in Germany).
The sensors of the AS 1000 series carry the CE mark. A declaration of conformity is available on
request. The sensor conforms to EMC standards: EN 61000-6-1, EN 61000-6-2, EN 61000-6-3
and EN 61000-6-4. The requirements of the standards are fulfilled only if the sensor housing is
earthed correctly by qualified personnel. When installing into a hydraulic block it is sufficient if the
block is earthed via the hydraulic system.
Additional assembly notes which, from experience, reduce the effect of electromagnetic
interference:
Make inline connections as short as possible.
Use screened cables (e.g. LIYCY 5 x 0.5 mm²).
The cable-screening must be fitted by a qualified person subject to the ambient conditions
and with the aim of suppressing interference.
Direct proximity to connecting lines of user units or electrical or electronic units causing
interference must be avoided as far as possible.
