Important Notes
Safety note
Danger
When loosening the conductivity transmitter steam or hot water might escape. This
presents the danger of severe scalding. It is therefore essential not to remove the
conductivity transmitter unless the boiler pressure is verified to be 0 bar.
The conductivity transmitter becomes hot during operation. This presents the risk of
severe burns to hands arms when the equipment is touched.
Installation, de-installation and maintenance work should only be carried out when the
system is cold.
The equipment must only be installed and commissioned by qualified and competent staff.
Retrofitting and maintenance work must only be performed by qualified personnel who – through
adequate training – have achieved a recognised level of competence.
Usage for the intended purpose
Use conductivity transmitters LRGT 16-1, LRGT 16-2 and LRGT 17-1 only for measuring the electrical
conductivity in liquids.
When used for conductivity limiting or continuous boiler blowdown in steam boilers the conductivity
transmitters LRGT 16-1, LRGT 16-2 and LRGT 17-1 must only be used in conjunction with the industrial
controller KS 90-1.
To ensure trouble-free operation the requirements made on water quality according to TRD and EN
regulations must be met.
Use the equipment only within the specified pressure and temperature ratings.
Any type of use differing from the usage described above is considered as improper. The resulting risk
will have to be borne by the user alone. The manufacturer hereby expressly rejects any claims for any
resulting damage.
ATEX (Atmosphère Explosible)
According to the European Directive 94/9/EC the equipment must
not
be used in explosion risk areas.
