3 Material Specifications of Wetted Components
Flow switch
•
Caution: Danger of death due to high voltages!
Always de-energize the system before connecting the connector cable.
•
It is prohibited to remove or make type plates or any other information attached to the equipment
indecipherable, otherwise all warranties and the responsibility of the manufacturer no longer apply.
2.3 Additional information for flow switch version VH...X
•
The flow switch should only come into contact with media with a minimum ignition temperature of >135 °C
and ignition energy of >60µJ.
•
When installing and before starting-up, it is to be guaranteed that the mechanical process connections are
technically tight.
•
Always consider the impermeability of the screwing elements for the zone allocation. Depending on the
operating conditions, it may be necessary to regularly check the impermeability of the screwing elements.
CAUTION:
Ensure that the maximum electrical contact load specified on the type plate is never exceeded;
otherwise the reed contact integrated in the switching unit will be damaged.
The switching capacity is reduced with inductive loads. Details of the protective circuit can be requested from
the manufacturer.
