Intended use
The BTL7 Micropulse Transducer, together with a machine 
controller (e.g. PLC), comprises a position measuring 
system. It is intended to be installed into a machine or 
system. Flawless function in accordance with the 
specifications in the technical data is ensured only when 
using original BALLUFF accessories. Use of any other 
components will void the warranty.
Opening the transducer or non-approved use are not 
permitted and will result in the loss of warranty and liability 
claims against the manufacturer.
General safety notes
Installation and startup may only be performed by 
trained specialists.
The operator is responsible for ensuring that local safety 
regulations are observed. In particular, the operator must 
take steps to ensure that a defect in the position 
measuring system will not result in hazards to persons or 
equipment.
If defects and unresolvable faults occur in the transducer, it 
should be taken out of service and secured against 
unauthorized use.
