Flow switch
2 Safety Instructions
Always read these operating instructions carefully prior to installing the new product. Always adhere to the
instructions contained herein, especially the safety instructions, otherwise there is a potential risk of personal
injury and damage to instruments and plants.
Even though
JLSO
provides assistance through personal consultation or the respective literature, it is the
responsibility of the customers to determine the suitability of the product for the specific application.
The flow switches are state-of-the-art devices. This concerns switching point accuracy, functioning and safe
operation of the device.
However, professional and safety conscious conduct of the operator is required to ensure safe operation.
2.1 Qualified personnel
•
The personnel entrusted with installing, operating and maintaining the flow switches have to be suitably
qualified; the required knowledge can be gained via training courses or appropriate on-the-job instruction.
The personnel have to be familiar with the contents of these instructions, which have to be available to
them at all times.
•
The electrical connection should only be carried out by a fully qualified electrician.
•
All work has to be carried out in accordance with existing national regulations on accident prevention and
safety at work and with any internal regulations of the operator, even if they are not specified in these
instructions.
2.2 Special safety instructions
•
The operational safety of the supplied equipment is only guaranteed if it is operated according to its
intended use. The specified limit values (see the chapter entitled “Technical Data“) should never be
exceeded.
•
To avoid damages to the flow switch and the monitored system, only use
JLSO
flow switches for minimum
or maximum monitoring of the flow of liquids.
•
Always follow and adhere to the flow switch installation instructions.
•
Never operate the flow switch in systems which have a greater flow rate than the specified max. flow rate
(see the chapter entitled “Technical Data”, details of the max. flow rate). Otherwise it will cause
irreparable damage to the flow switch.
•
Prior to flow switch installation, ensure that all the materials of the flow switch are chemically and
mechanically-resistant to the medium which is to be monitored and to all external factors.
•
Ensure that the medium is free from magnetic particles.
•
Suitable measures should be taken to prevent the medium from freezing.
If the flow switch is to be used in ambient temperatures of <4 °C, do not carry out any operation
beforehand with pure water, e.g. a test run. Residual water in the flow switch can result in frost damage.
•
No greases, oils etc. should be used during the installation of the VK... devices due to the material
resistance.
•
Ensure that the max. specified operating pressure is not exceeded.
•
Never remove a flow switch or its upper parts from a pipe system under pressure.
•
If the medium which is to be monitored is very hot, the flow switches or their connection fittings will also
become very hot. In this case, neither touch the flow switch nor place any heat-sensitive objects in its
vicinity.
•
Protect the flow switch against external magnetic fields in the immediate vicinity, since these can impair
device functioning.
•
The technical data of special versions (customised versions) can deviate from the details in these
instructions. Please observe the details on the type plate.
