Training
Definition
Electrical technician
An electrical technician is able to complete work on electrical systems
and recognise and avoid possible dangers independently based on his
technical training and experience as well as knowledge of pertinent
standards and regulations. An electrical technician must be able to per‐
form the tasks assigned to him independently with the assistance of
drawing documentation, parts lists, terminal and circuit diagrams. The
electrical technician must be specifically trained for the working environ‐
ment in which the electrical technician is employed and be conversant
with the relevant standards and regulations.
Service
The Service department refers to service technicians, who have
received proven training and have been authorised by the manufacturer
to work on the system.
1.3 General safety information
Unauthorised access!
Ensure that there can be no unauthorised
access to the device.
Only trained personnel may fit, install, maintain
and operate this sensor.
Functional limitations
Regularly check the sensor for dirt.
Check the diaphragm cap regularly for air bub‐
bles adhering to it (visual check).
Observe the applicable national guidelines
relating to maintenance, service and calibration
intervals.
Operational prerequisites
Only use the sensor in bypass fittings that
ensure the correct flow parameters (l/h, see
Technical data).
Ensure that there is a free flow or at most a
back pressure of 1 bar at the outlet of the
bypass fitting. Note the maximum operating
pressure for the individual components.
Damage cannot be ruled out if the sensor is
operated for longer than approx. one week in
process water without feed chemical. Switch off
the sensor electrically during longer pauses.
It is necessary to run in and recalibrate the
sensor following longer interruptions to the
power supply (> 2 h).
Damage cannot be ruled out if the sensor is
operated for longer than approx. one week
without chlorine dioxide. Switch off the sensor
electrically during longer pauses.
1.4 Intended use
The sensor may only be used to determine and
control concentrations of chlorine dioxide (ClO
2
)
in water.
