The ignition hazard analysis conducted
in accordance with EN 80079-36 / -37
found that SKF flow limiters of series SP/
SMB3 and SP/SMB6 without electrical at-
tachments do not constitute own potential
sources of ignition. They consequently do not
fall under the scope of Directive 2014/34/EU
and thus do not bear explosion protection
marking.
To better incorporate the flow limiters into
the operator's explosion protection concept,
these flow limiters have been equipped with
an equipotential bonding terminal. No addi-
tional ignition source results from the com-
bination of the flow limiters described with
the signal transmitters specified in these
instructions, as they are to be classified as
simple electrical equipment in accordance
with EN 60079-14, No. 16.4.
These flow limiters are designated as ATEX
flow limiters in the following.
Classification of the explosion protection marking in the flow limiters in accordance with ignition hazard analysis in accordance with EN ISO 80079-36 /-37

EU
We hereby confirm that the following signal
transmitters
Designation: 24-1072-2116
24-1072-2054
24-1072-2055
Year of manufacture: See type plate
are merely passive switching elements with
a max. internal capacitance of Ci=1nF and
an internal inductance of Li = 5µH
and in their entirety do not contain any own
ignition sources.
The signal transmitters 24-1072-2116,
24-1072-2054 and 24-1072-2055 are
passive elements that, for the purpose of
the intrinsically safe protection type "i," are
pieces of simple electrical equipment and
are treated in standard DIN EN 600079-
11, No. 5.7, when connected to an intrinsi-
cally safe electrical circuit with maximum
values:
Ui = 30 V
Pi = 1 W
I
i
= 100 mA
Simple electrical equipment of this kind is
independent of the device level.
Simple electrical equipment must be clearly
identifiable by permanent labeling. It can be
labeled by the constructor by some kind of
designation marking or coding that is pre-
ferred for the system.
SKF affixes this marking via the signal
transmitter’s blue connection cable or via a
blue screw union.

1.1 General safety instructions
○The operator must ensure that the in-
structions are read by all persons tasked
with working on the product or who
supervise or instruct such persons. The
operator must also ensure that the staff
fully understands the content of the in-
structions. Putting the products into op-
eration or operating them without having
read the instructions is prohibited.
○Retain the instructions for further use.
○The products described here were
manufactured in accordance with current
state-of-the-art technology. Risks may,
however, arise from non-compliant us-
age and may result in personal injury or
damage to material assets.
○Any malfunctions which may affect safety
must be remedied immediately. In ad-
dition to these instructions, the statu-
tory regulations for accident prevention
and environmental protection must be
observed.
1.2 General behavior when handling the
product
○The product may only be used in aware-
ness of the potential dangers, in proper
technical condition, and according to the
information in this manual.
○Familiarize yourself with the functions
and operation of the product. The speci-
fied assembly and operating steps and
their sequences must be observed.
○Any unclear points regarding proper con-
dition or correct assembly/operation must
be clarified. Operation is prohibited until
issues have been clarified.
○Unauthorized persons must be kept
away.
○Wear personal protective gear.
○All safety regulations and in-house in-
structions relevant to the particular activ-
ity must be observed.
○Responsibilities for different activities
must be clearly defined and observed.
Uncertainty seriously endangers safety.
○Guards and safety devices must not be
removed, modified, nor disabled during
operation and must be checked for prop-
er function and completeness at regular
intervals.
○If protective and safety mechanisms must
be removed, they must be reinstalled
immediately following conclusion of work
and then inspected for proper function.
○Any malfunctions that occur must be
resolved according to responsibility. The
supervisor must be notified immediately
in case of malfunctions outside one's in-
dividual scope of responsibility.
○Never use any part of the centralized
lubrication system as a stand or step or
for climbing.

1.3 Intended use
Feed lubricants only in compliance with the
specifications, technical data, and limits pre-
sented in this manual.
Signal transmitters of series 24-1072-
2116, 24-1072-2054 and 24-1072-2055
are used to monitor the volumetric flow
within an ATEX-compliant SKF flow limiter.
The signal transmitters with built-in dry
contact are classified as simple electri-
cal equipment and are in accordance with
the requirements of the standard DIN EN
60079-11, No. 5.7. They may be used only
in intrinsically safe circuits.
The data and values listed in the "Technical
data" chapter must be observed.
Usage is permitted exclusively in the context
of commercial or business activity by profes-
sional users.
1.4 Foreseeable misuse
Any usage of the product other than as
specified in this manual is strictly prohibited.
Particularly prohibited are:
○Use outside the specified operating tem-
perature range
○Use of non-specified equipment
○Use without a pressure relief valve
○Use in areas with aggressive, corrosive
substances (e.g., high ozone loads)
○Use in areas with damaging radiation
(e.g., ionizing radiation)
○Use to feed, forward, or store hazardous
substances and mixtures as defined in
Annex I Part 2-5 of the CLP Regulation
(EC 1272/2008) that are marked with
hazard pictograms GHS01-GHS 09.
○Use to feed / forward / store gases, lique-
fied gases, dissolved gases, vapors, or
fluids whose vapor pressure exceeds nor-
mal atmospheric pressure (1013 mbar)
by more than 0.5 bar at their maximum
permissible operating temperature
○Use in another, more critical explosion
protection zone
