2 General information
The level measuring instrument VEGAPULS PS61(*).C****P/K/F/L**** is based on radar technology
and is used to detect the distance between product surface and sensor by means of high frequency
electromagnetic waves in the GHz range. The electronics uses the running time of the signals
reected by the product surface to calculate the distance to the product surface.
The VEGAPULS PS61(*).C****P/K/F/L**** consist of an electronics housing, a process connection
element and a sensor (the antenna). As an option the display and adjustment module can also be
integrated.
The measured products can also be combustible liquids, gases, mist or vapour.
The VEGAPULS PS61(*).C****P/K/F/L**** are suitable for use in hazardous atmospheres of all
combustible materials of explosion group IIA, IIB and IIC for applications requiring instruments of
category 1G, category 1/2G or category 2G.
If the VEGAPULS PS61(*).C****P/K/F/L**** are installed and operated in hazardous areas, the gen-
eral Ex installation regulations EN 60079-14 as well as these safety instructions must be observed.
The operating instructions as well as the installation regulations or standards that apply for explo-
sion protection of electrical systems must generally be observed.
The installation of explosion-endangered systems must always be carried out by qualied person-
nel.

5 Applicationconditions
The max. permissible ambient temperatures depending on the temperature classes are specied in
the following tables.
For assessment and reduction of the explosion risk, valid standards such as for example EN 1127-1
must be taken into account.

between 0.8 … 1.1 bar. If the VEGAPULS PS61(*).C****P/K/F/L**** are operated at temperatures
higher than those specied in the above table, please make sure by means of appropriate measures
that there is no danger of ignition from the hot surfaces. The max. permissible temperature on the
electronics/housing should not exceed the values according to the above table.
Please make sure that the sensor also in case of failure does not generate heat itself. Responsibility
for safe operation of the equipment, with respect to pressures/temperatures of the materials used,
rests with the operator.
The prerequisites for operation in the absence of explosive mixtures can be found in the manufac-
turer specications.

6 Protection against static electricity
The VEGAPULS PS61(*).C****P/K/F/L**** in versions with electrostatically chargeable plastic parts,

9
VEGAPULS 61
37991-EN-200303
such as e.g. plastic housing, metal housing with inspection window or plastic antenna, have a cau-
tion label pointing out the safety measures that must be taken with regard to electrostatic charges
during operation.
WARNING - POTENTIAL ELECTROSTATIC
CHARGING HAZARD - SEE INSTRUCTIONS
Caution: Plastic parts! Danger of electrostatic charging!
• Avoid friction
• No dry cleaning
• Construction/Installation: The VEGAPULS PS61(*).C****P/K/F/L**** must be constructed/
installed in such a way that
– electrostatic charges are ruled out during operation, maintenance and cleaning.
– process-related electrostatic charges, e.g. by measuring media owing past, are ruled out
7 Use of an overvoltage arrester
If necessary, a suitable overvoltage arrester can be connected in front of the VEGAPULS
PS61(*).C****P/K/F/L****.
When used as category 1G or 1/2G instrument, a suitable overvoltage arrester must be connected
in between as protection against overvoltages, as far as required according to EN 60079-14.
8 Grounding
In order to avoid the danger of electrostatic charging of the metallic parts, the VEGAPULS
PS61(*).C****P/K/F/L**** must be electrostatically connected to the local potential equalisation
(transfer resistance ≤ 1 MΩ), e.g. via the ground terminal, when used as category 1G or 1/2G instru-
ments.
Metallic adapter anges must be earthed, especially when installed on non-conductive plastic ves-
sels or non-earthed vessels. Earthing can be realised with cable lug via the ange gland.
9 Impactandfrictionsparks
When used as category 1G instruments, the VEGAPULS PS61(*).C****P/K/F/L**** in aluminium/
titanium versions must be mounted in such a way that sparks from impact and friction between alu-
minium/titanium and steel (except stainless steel, if the presence of rust particles can be excluded)
cannot occur.
10 Material resistance
For applications requiring instruments of category 1G or category 1/2G the VEGAPULS
PS61(*).C****P/K/F/L**** must only be used in products against which the wetted materials are suf-
ciently resistant.
11 MountingwithexternaldisplayunitVEGADIS61/81
The intrinsically safe signal circuit between VEGAPULS PS61(*).C****P/K/F/L**** and the external
indicating unit VEGADIS 61/81 should be set up without grounding. The required insulation voltage
is > 500 V AC. When using the VEGA connection cable included with the delivery, this requirement
is fullled. If grounding of the cable screen is required, it must be carried out according to EN 60079-
14.

12 Removingandreplacingtheredthreaded/dustcover
When the VEGAPULS PS61(*).C****P/K/F/L**** are delivered, depending on the version, the red
threaded or dust protection caps must be removed before installing the device and the openings
must be sealed according to the requirements of the type of protection and the IP protection type
specied on the type label.
When using certied i.e. suitable cable glands, sealing plugs or plug connectors, they must be
mounted correctly and the respective certicates/documents must be observed.
The sealing plugs included in the delivery by VEGA meet the necessary requirements.
