6. Maintenance
The magnetic operated float switches operate free of maintenance
and wear when used properly.
The switch must be eye-checked within the scope of the necessary
inspections under extreme operating conditions.
7. Notes
The reed contacts must be operated on intrinsically safe circuits when
operating in „e“ areas of zone 1 or 2.
Float switches made of plastic may not be used in the „e“ areas of
zone 1 or 2.
Do not operate float switches in the immediate vicinity of strong
electromagnetic fields (distance away at least 1 m).
The switching points of the magnetic operated float switches cannot
be adjusted.
Magnetic operated float switches can only be used in media to which
the material of the slip pipe and the float is resistant.
The switches may not be exposed to heavy mechanical stresses
(shock, bending, vibrations).
