ATEX
The acronym ATEX is the French abbreviation for
"Atmosphère explosible" and refers to the two
European Union (EU) directives covering the area
of explosion protection: ATEX Equipment Directive
2014/34/EU (also referred to as ATEX 95) and ATEX
Workplace Directive 1999/92/EC (also referred to
as ATEX 137).
Bubbler control with compressor
The air compressor is integrated in the measuring
system in addition to the pneumatic level
measurement. Condensation can be discharged.
Certificate of decontamination
A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.
DIN 1986-3 and -30
German standard which stipulates technical rules
for the operation, maintenance and servicing of
drainage systems in buildings and on premises
Discharge line
Pipe for transporting waste water to a level above
the flood level into the sewer system
DOL starting
For low power ratings (usually up to 4 kW), the
three-phase motor is connected directly to the
mains voltage.
Effective volume
Volume in the collection tank between start and
stop level that can be lifted
EN 12 056-4
European standard governing the selection,
operation and maintenance of sewage lifting units
within buildings and sites.
EN 12050-1
European Standard for sewage lifting units which
are used to dispose of sewage with faeces
occurring below the flood level of buildings and
land. It defines general requirements as well as
principles of construction and testing.
Flood level
Maximum backflow level of waste water in a
drainage system
Inlet line
Pipe used for draining waste water from sanitary
installations into the lifting unit
Nominal diameter DN
Identifier (inside diameter) used for characterising
mating components such as pipes, pipe
connections and fittings
Pneumatic level measurement
Determining the liquid level in the tank by means
of a pressure sensor integrated in the control unit.
Separator
Device for physically separating the two phases of
a two-phase flow, e.g. for separating solid
particles or liquid drops from flowing gases.
Sewage lifting unit
Device for collecting and automatically lifting
waste water with or without faeces above the
flood level
Soft starting
Measures taken to limit the output of a power
supply unit or electric motor, to limit the starting
current, and avoid excessive acceleration and
torques.
Star/delta starting
For starting large three-phase squirrel-cage motors
(5.5 kW and above). Prevents voltage dips and
fuses from tripping. Used if direct starting would
result in a high starting current.
Stormwater
Water from natural precipitation which has not
been contaminated by any form of use
Vent line
Pipe provided to limit pressure fluctuations within
the sewage lifting unit. The vent line is led
through the roof.
Waste water
Water which has been changed by some type of
use, e.g. domestic waste water
