Dear customer,
Your VACUUBRAND vacuum gauge shall support you at your work for a long time without any trouble
and with full load output. Thanks to our large practical experience we attained much information how you
could add to an efcient application and to personal safety. Please read these instructions for use prior
to the initial start-up of your controller.
VACUUBRAND vacuum gauges are the result of many years of experience in construction and practical operation of these vacuum gauges combined with the latest results in material and manufacturing
technology.
Our quality maxim is the ”zero fault principle”:
Every delivered vacuum gauge is tested extensively including an endurance run. Due to this endurance
run, also faults, which occur rarely, are reported an can be corrected. Every single vacuum gauge is
tested on achievement of the specication after the endurance run.
Every VACUUBRAND controller leaving our factory achieves the specication. We feel obliged
to this high quality standard.
We are aware that the controller should not draw a part of the real work and we hope to contribute with
our products to an effective and troublefree realisation of your work.
Yours
VACUUBRAND GMBH + CO KG

NOTICE
Read and comply with this manual before installing or operating the equipment.
Remove all packing material, remove the product from its packing-box, remove the
protective covers and keep, inspect the equipment.
If the equipment is damaged, notify the supplier and the carrier in writing within three
days; state the item number of the product together with the order number and the
supplier’s invoice number. Retain all packing material for inspection.
Do not use the equipment if it is damaged.
If the equipment is not used immediately, replace the protective covers. Store the
equipment in suitable conditions.
Intended use
• The devices DVR 3 are electronic rough vacuum gauges of the facility performance group II for the intended use in hazardous areas. They have a special
approval and are subject to the guideline 94/9/EG (see ”Declaration of Conformity)”.
• Respect the permitted connection parameters.
Attention: DVR 3 has only an approval for zone 1 and zone 2.
• Electrical and vacuum components might require a separate approval (see also
”Accessories”).
• The device is designed for ambient and gas temperatures at the pressure trans-
ducer connection of +10°C to +40°C at continuous operation, up to +80°C for
short periods (< 5 minutes) at the pressure transducer. If installing the device into
a cabinet or a housing check maximum temperature. Ensure that the maximum
permitted gas temperature at the pressure transducer (see ”Technical data”) is
not exceeded.
NOTICE
Use the equipment and all system parts for the intended use only, i.e. for measurement of vacuum in vessels designed for that purpose.
Connecting the device
• Connect the vacuum gauge to the vacuum application.
• Position the vacuum gauge and its vacuum connection line so that condensate
cannot ow towards the internal pressure transducer.
• Connect hoses at the pressure transducer connection gas tight.
• Ensure stability of the hose connection.
• Comply with all relevant safety requirements.
☞ Avoid uncontrolled overpressure (e. g. when connecting to a locked or blocked
tubing system). Risk of bursting.
☞ The power supply unit BVE 9V is an intrinsically safe electrical operating device
of the facility performance category 2 (PTB 98 ATEX 2206). The user can replace
the sealed power supply unit of vacuum gauges DVR 3 within the hazardous
area of category 2 (according to the approvals of power supply unit and vacuum
gauge). Further interventions and repair must only be done by the manufacturer.
☞ Using non-genuine power supply units or doing further interventions void the ap-
proval for use in explosive areas.
• Power supply by an power supply unit BVE 9V. Do not charge the battery. Do not
open the battery. Do not throw the battery into re. Do not heat over 100°C and
do not bring in contact with water.

• Comply with max. permitted ambient and gas temperature (see ”Technical
data”) and make sure ventilation is adequate if the equipment is installed in a
housing or if ambient temperature is elevated.
• Avoid high heat supply (e. g. due to hot process gases).
• In case of residues or aggressive or condensable media install a gas washing
bottle if necessary.
NOTICE
NOTICE
When the device is brought from cold environment into a warm room for operation
bedewing may occur. Allow the device to acclimatize.
Comply with national safety regulations and safety requirements concerning the
use of vacuum and electrical equipment. Comply with all applicable and relevant
safety requirements (regulations and guidelines), implement the required ac-
tions and adopt suitable safety measures.
Operating conditions
➨ DVR 3 has only an approval according to device labelling.
Ensure that the materials of the wetted parts are compatible with the substances
processed in the vacuum system, see section “Technical data”.
Safety during operation
➨ Adopt suitable measures to prevent the release of dangerous, toxic, explosive,
corrosive, noxious or polluting uids, vapors and gases.
➨ Prevent any part of the human body from coming in contact with the vacuum.
Max. permitted pressure at the vacuum gauge: 1.1 bar absolute with hose nozzle;
1.5 bar absolute with small ange connection.
• The display ashes at a pressure above 1060 mbar.
☞ Attention: If the pressure is higher than approximately 1060 mbar the pressure
reading becomes incorrect (saturation of the pressure transducer). The display
ashes. Immediate pressure relief necessary! Risk of bursting!
• Use only genuine spare parts and accessories. Otherwise safety and perfor-
mance of the equipment as well as the electromagnetic compatibility of the equipment might be reduced.
Possibly the CE mark becomes void if not using OEM spare parts.
Electronic equipment is never 100% fail-safe. This may lead to an ill-dened sta-

tus of the equipment or of other connected devices. Provide protective measures
against malfunction and failure. Ensure that in case of failure the device and the
vacuum system always will turn into a safe status.

Maintenance and repair
• Attention: Due to the operation the equipment might be contaminated by harmful
or dangerous substances, clean or decontaminate prior to maintenance.
The user can replace the sealed power supply unit of vacuum gauges DVR 3 within
the hazardous area (according to the approvals of power supply unit and vacuum
gauge). Further interventions and repair must only be done by the manufacturer.
Returned products will not be repaired or calibrated until the completed health and
safety clearance form has been received. In order to comply with law (occupational,
health and safety regulations, safety at work law and regulations for environmental
protection) vacuum pumps, components and measuring instruments returned to the
manufacturer can be repaired only when certain procedures (see section ”Notes on
return to the factory”) are followed.
