Warning/Attention
1. GENERAL
SET/V is a level switch sensor that is to be con-
nected to analogical and digital SET control units of
Labkotec. Operating principle of the sensor is based
on the measurement of the vibration of the sensor.
Sensor is suitable to be used as a high level alarm
for liquid tanks, for example. Typical applications of
SET/V sensor include oil and grease separators.
The SET/V has been certified according to the
ATEX Directive in equipment category 1 and it can
be installed in potentially explosive atmospheres in
zoned areas 0, 1, and 2.

The sensor may be installed in potentially
explosive atmospheres of zones 0, 1, and 2
with the following special conditions (X):
–The ambient temperature is –30…+60°C.
–The risk of electrostatic charge must be observed!
Standards to be considered in the installation:
IEC/EN 60079-25 Intrinsically-safe electrical systems "i",
and/or IEC/EN 60079-14 Electrical installations in haz-
ardous areas. If the cabling is voltage-tested, the sensor
must be detached from the system.

3. CONNECTIONS AND INSTALLATION
The SET/V sensor is equipped with a shielded 2-
wire cable. The numbered wires 1 and 2 of the cable
are connected to the corresponding connectors (1 =
+, 2 = –) in the control unit. Always check the con-
nections from the installation and operation manual
of the control unit as well.
In the example shown in figure 4A, an LJB2-78-83
junction box has been used to connect the cabling
to the equipotential bonding.
In figures 4B and 4C, equipotential bonding is not
available. The shield is connected to the appropriate
connector in the supply device.
In these kinds of arrangements, it must be
ensured that the electrostatic charges do not
cause a hazard. Make sure in the installation that
the device and cabling are not close to a strong
current or other installations and that they are not
exposed to strong stream flows, mechanical
abrasions, or impacts.
The cable may be shortened or extended with a
junction box, if necessary.
The sensor is installed by hanging it from its cable at a
suitable height so that the switch data is received as
the surface level reaches the sensing element.

4. OPERATION
This chapter provides a general description of the
operation of the alarm in different situations. For a
more detailed description, please refer to the man-
ual of the control unit in use.
5. OPERATION TEST
Always check the correct operation of the alarm af-
ter the installation and after making the connections.
You should also check the operation every time the
separator is emptied or at least once a year.
Testing the
operation
1. The sensor is in the air. The de-
vice should be in normal mode
(see chapter 4).
2. Lower the sensing element of the
sensor into the water or oil. The
“Tank full” alarm should be issued
(see chapter 4).
3. Lift the sensor in the air. The
alarm should stop after a while.
Clean the sensor before installing
it into the separator.
If the sensor does not function as described, check
the device settings from the control unit manual or
contact the representative of the manufacturer.
6. SERVICE AND REPAIR
The sensor must be cleaned and tested when emp-
tying the storage chamber and in connection with
the annual maintenance. A mild detergent (e.g.
washing-up liquid) and a scrubbing brush can be
used for cleaning the sensor, if necessary.
In fault situation check the cabling and connections
of possible short-circuits or interruptions, then, if
necessary, measure the sensor current and com-
pare it with current values below.
Attention! If the sensor is located in an explosive at-
mosphere, the multimeter must be Exi-approved!
Sensor (clean/dry) in the air:
5 –8 mA
Sensor in the water/oil:
10 –14 mA
Also measure the output voltage of control unit. It is
typically between 10 –12 V with Labkotec Oy’s
SET-control units. See details from the manual of
the control unit.
In case of queries, please contact Labkotec Oy’s
service.
During maintenance procedures (such as servic-
ing the oil/fuel separator systems), the sensor
should not be lifted out of the separa-
tor tank or installed back until there is
water in the tank.
The instructions concerning the inspection and
maintenance of Ex equipment contained in stand-
ards IEC/EN 60079-17 and IEC/EN 60079-19
should be observed when executing service, in-
spection, or repair procedures.
LevelSET S CONTROL UNIT:
See settings of LevelSET S control unit from its Op-
eration and Installation Manual.
Write down the 5 digit address from the
Code field of the sensor type plate in the in-
stallation phase for later use. This address
is required if the sensor has to be re-connected to
the LevelSET S system or another control unit.
