1.3 Warning and safety information
The TitroLine
®
5000 corresponds to protection class III. It was manufactured and tested according to DIN EN
61 010, Part 1, Protective Measures for electronic measurement devices and control devices and has left the
factory in an impeccable condition as concerns safety technology. In order to maintain this condition and to
ensure safe operation, the user should observe the notes and warning information contained in the present
operating instructions. Development and production is done within a system which meets the requirements laid
down in the DIN EN ISO 9001 standard.
For reasons of safety, the titrator TitroLine
®
5000 must be opened by authorised persons only; this means, for
instance, that work on electrical equipment must only be performed by qualified specialists.
In the case of nonobservance of these provisions the titrator TitroLine
®
5000 may constitute a
danger: electrical accidents of persons or fire hazard. Moreover, in the case of unauthorised
intervention in the titrator TitroLine
®
5000 as well as in the case of negligently or deliberately caused
damage, the warranty will become void.
Prior to switching the device on it has to be ensured that the operating voltage of the titrator TitroLine
®
5000
matches the mains voltage. The operating voltage is indicated on the specification plate. Nonobservance of
this provision may result in damage to the titrator TitroLine
®
5000 or in personal injury or damage to property.
If it has to be assumed that safe operation is impossible, the titrator TitroLine
®
5000 has to be put out of
operation and secured against inadvertent putting to operation. In this case please switch the titrator TitroLine
®
5000 off, pull plug of the mains cable out of the mains socket, and remove the titrator TitroLine
®
5000 from the
place of work.
Examples for the assumption that a safe operation is no longer possible,
the package is damaged,
the titrator TitroLine® 5000 shows visible damages,
titrator TitroLine® 5000 does not function properly,
liquid has penetrated into the casing.
If the titrator TitroLine® 5000 has been altered technologically or if unauthorized personnel tried or
succeeded to open the instrument as attempt to repair it.
In case that the user operates such a device, all thereof resulting risks are on the user.
The titrator TitroLine
®
5000 must not be stored or operated in humid rooms.
For reasons of safety, the titrator TitroLine
®
5000 must only be used for the range of application described in
the present operating instructions.
In the case of deviations from the intended proper use of the device, it is up to the user to evaluate the
occurring risks.
The relevant regulations regarding the handling of the substances used have to be observed:
The
Decree on Hazardous Matters, the Chemicals Act, and the rules and information of the chemicals trade. It
has to be ensured on the side of the user that the persons entrusted with the use of the titrator TitroLine
®
5000 are experts in the handling of substances used in the environment and in titrator TitroLine
®
5000 or that
they are supervised by specialised persons, respectively.
During all work with titration solutions:
Please wear protective glasses!
The titrator TitroLine
®
5000 is equipped with integrated circuits (EPROMs). X rays or other high energy
radiation may penetrate through the device’s casing and delete the program.
For working with liquids, not beeing common titration solvents, especially the chemical resistance of the
construction materials of the titrator TitroLine
®
5000 have to be considered (please also refer to chapter 1.1).
For the use of liquids with high vapour pressure or (mixture of) substances not being mentioned in chapter 1.1
as allowed substances, the safe and proper operation of the titrator TitroLine
®
5000 has to be guaranteed by
the user.
When the piston moves upwards within the cylinder, a microfilm of dosing liquid or titration solution will always
remain adhered to the inner wall of the cylinder, but this has no influence on the dosing accuracy. This small
residue of liquid, however, may evaporate and thus penetrate into the zone underneath the piston, and if non-
admitted liquids are being used, the materials of the titrator TitroLine
®
5000 may be dissolved or corroded
(please refer also to chapter 8 “Maintenance and Care of the titrator TitroLine
®
5000
”).
