Dear customer,
Your VACUUBRAND vacuum controller 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 controllers are the result of many years of experience in construction and practical operation of these vacuum controllers combined with the latest results in material and manufacturing technology.
Our quality maxim is the ”zero fault principle”:
Every delivered vacuum controller 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 control-
ler 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 trouble-free realisation of your work.
Yours

”p Error” is displayed and the controller sounds ve blips.
☞ Use only original manufacturer’s spare parts and accessories. Otherwise the
safety and performance of the equipment, as well as the electromagnetic compatibility of the equipment might be reduced.
The CE mark or the cTÜVus mark may be voided if not using original manufac-
turer’s spare parts.
NOTICE
• Switching of an in-line valve or a vacuum pump, or opening of a venting valve by
the controller must not lead to a critical dangerous situation under any circumstances.
• Attention: If Auto-Start ”Auto-St.” is preselected, the process starts immedi-
ately after a power failure without pressing any further key. It is the user’s responsibility to ensure that no dangerous status of the system due to the automatic
start-up can occur and to provide appropriate safety measures. If necessary, the
user has to check prior to starting process control, whether the option ”AutoStart” is enabled.
Electronic equipment is never 100% fail-safe. This may lead to an ill-dened status of the equipment or of other connected devices. Provide appropriate protective
measures to allow for the possibility of failure and malfunction. The protective measures must also allow for the requirements of the respective application.
Maintenance and repair
➨ Switch off the vacuum controller.
➨ Disconnect the power supply and wait two minutes before starting maintenance
to allow the capacitors to discharge.
➨ Note: The equipment may be contaminated with chemicals, which have been
processed during operation. Ensure that the equipment is completely decontaminated before maintenance commences. Take adequate precautions to protect
people from the effects of dangerous substances if contamination has occurred.
Use appropriate protective clothing, safety goggles and protective gloves.

and
VACUUBRAND equipment bearing mark (see rating plate)
X see manual
For equipment labelled with „ X see manual“ the following classication according to Directive 94/9/EC (ATEX) is
valid:
The classication II 3G IIC T3 X according to ATEX is only valid for the inner part (wetted part, pumped gas or vapor)
of the equipment. The equipment is not suitable for use in external, potentially explosive atmospheres (environment).
II 3G IIC T3 X, Internal Atm. only, Tech. File Ref.: VAC-EX01.
The overall category of the equipment depends on the connected components. If the connected components do not
comply with the classication of the VACUUBRAND equipment, the specied category of the VACUUBRAND equipment is no longer valid.
Vacuum pumps and vacuum gauges in category 3 are intended for connection to equipment in which during normal
operation explosive atmospheres caused by gases, vapors or mists normally don’t occur or, if they do occur, are likely
to do so only infrequently and for a short period only.
Equipment in this category ensures the requisite level of protection during normal operation.
The use of gas ballast or the operation of venting valves is only permitted if thereby explosive atmospheres normally
don’t occur in the interior of the equipment or, if they do occur, are likely to do so only infrequently and for a short
period.
The pumps are marked with ”X” (according to EN 13463-1), i.e., restrictions of the operation conditions:
• The equipment is designated for a low degree of mechanical stress and has to be installed in a way so that it cannot be damaged from outside.
Pumping units have to be installed protected against shocks from the outside and against glass splinters in the
event of breaking (implosion).
• The equipment is designated for an ambient and gas inlet temperature during operation of +10 to +40°C. Never
exceed these ambient and gas inlet temperatures. If pumping / measuring gases which are not potentially explosive, extended gas inlet temperatures are valid, see instructions for use, section “Gas inlet temperatures” or
“Technical data”.
After any intervention at the equipment (e.g., repair / maintenance) the ultimate vacuum of the pump has to be
checked. Only if the pump achieves its specied ultimate vacuum, the pump’s leak rate is low enough to ensure that
no explosive atmospheres will occur in the interior of the equipment.
After any intervention at the vacuum sensor the leak rate of the equipment has to be checked.
Attention: This manual is not available in all languages of the EU. The
