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 . HYDACLab ® sensors have been individually
calibrated on computer-aided test benches and subjected to a final test. They operate perfectly
when used according to the specifications (see Technical Specifications).
However, if there is a cause for complaint, please contact
HYDAC Service . Interference by
anybody other than HYDAC personnel will invalidate all warranty claims.
2. Safety instructions
The Fluid Condition Sensor HYDACLab ® presents no safety concerns when 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, check that the unit is in perfect condition.
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 HYDACLab ® must not be put into service if any known defects 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 our customer service
department 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 property or personal injury can result.
3. Installation
The sensor can be installed directly in the hydraulic system via the threaded connection. It is
recommended that the sensor is mounted vertically with the electrical connector pointing
downwards. When fitting, ensure that the sensor is completely submerged in the fluid and that the
fluid can circulate freely through the sensor.
HYDAC ELECTRONIC provides appropriate accessories for installing the HYDACLab
® (see Chap.
11.1, Accessories, Mechanical).
The electrical connection must be carried out by a qualified electrician according to the relevant
regulations of the country concerned (VDE 0100 in Germany).
HYDACLab
® sensors carry the CE mark. A certificate of conformity will be provided on request.
EMC standards: EN 61000-6-1, EN 61000-6-2, EN 61000-6-3 and EN 61000-6-4
have all been met. However, the stipulations of those standards will be met only if the sensor's
housing has been correctly earthed by a qualified electrician. When fitted into a hydraulic block, it
is sufficient if the block is earthed via the hydraulic system.
Additional installation suggestions which, from experience, reduce the effect of electromagnetic
interference:
Make line connections as short as possible.
Use screened cabling (e.g. LIYCY 5 x 0.5 mm²).
The cable screening must be fitted by qualified personnel subject to the ambient conditions
and with the aim of suppressing interference.
Keep the unit well away from the electrical supply lines of power equipment, as well as from
any electrical or electronic equipment causing interference.
