9. Commissioning
When used in machines according to guideline 89/392/EWG commissioning is
prohibited until it is established that the machine meets the general requirements
of the guideline.
Setting limit values

Loosen both retaining screws at the contact stem
with a screwdriver.

Set the setting notch on the contact stem at the
desired value on the dial on the case.

Firmly tighten the retaining screws in this position.
Hysteresis
Hysteresis is the difference between contact closing
and opening points. A hysteresis of approximately 3.5-6 mm float move
(depending on the instrument model) is achieved by tuning magnet and contact
strength (AW number). Thus, bistable contact switching performance is also
assured.
Overrange
Attention! Avoid pulsating flow, as constant overranges due to
pulsating flows, which cause the float to strike against the float
stop, can lead to increased wear and tear and cause damage to the
instruments. In such cases contact the supplier.
The measuring range can be exceeded considerably with continuous streams,
only an increase in pressure loss is detected.
(Do not exceed allowed max. operating pressure)
10. Maintenance
The instrument needs no maintenance when the measured medium is clean.
Lime and other deposits should be removed regularly from the inside parts of the
instruments. Unscrew and remove instrument from pipe with open-ended spanner
wrench. Remove the top fitting to take out internal parts for cleaning. Clean
internal parts with a brush. Re-assemble the instrument in reverse order after
cleaning. We recommend that the O-ring on the fitting be replaced.
Attention! Make sure that the supply wires are de-energized before
beginning maintenance.
