Dear customer,

Your VACUUBRAND diaphragm pumps are designed to provide you with many years of trouble-free service with optimal performance. Our many years of practical experience allow us to provide a wealth of application and safety information. Please read these instructions for use before the initial operation of your pump. VACUUBRAND diaphragm pumps combine our many years of experience in design, construction and practical operation, with the latest developments in material and manufacturing technology.

Our quality maxim is the ”zero defect” principle: Every diaphragm pump, before leaving our factory, is tested intensively, including an endurance run of 14 hours. Any faults, even those which oc-

cur rarely, are identied and can be eliminated immediately.

After completion of the endurance run, every pump is tested, and must

achieve specications before shipment.

We are committed to providing our customers only pumps that meet this high quality standard. While our pumps cannot eliminate all of your work, we design, manufacture and test them to ensure that they will be an effective and trouble-free tool to assist you in that work.

Yours, VACUUBRAND GMBH + CO KG

After sales service: Contact your local dealer or call +49 9342 808-5500.

Page 14

page 14 of 121

+ Comply with all notes on correct vacuum and electri-

cal connections; see section „Use and operation“, pg.

38.

+ Do not use the pump to generate pressure.

+ The pumps are designed for ambient temperatures

during operation between +50°F and +104°F (+10°C and +40°C). Periodically check maximum temperatures if installing the pump in a cabinet or a housing. Make sure ventilation is adequate to maintain recommended operating temperature. Install an external automatic ventilation system if necessary. If pumping hot process gases, make sure that the maximum permitted

NOTICE

gas inlet temperature is not exceeded. The maximum permitted gas inlet temperature depends on several parameters like inlet pressure and ambient temperature (see „Technical data“, pg. 27).

+ Particles and dust must not enter the pump. + Do not pump liquids.

• Ensure that the pump, and any accessories in the ow

path are chemically resistant to the pumped substances prior to operation.

Use the equipment only as intended, that is, for generation, measurement, and control of vacuum in vessels designed for that purpose. Any other use will automatically invalidate all warranty and liability claims. Remain aware of safety and risks.

Setting up and installing the equipment

➨ Equipment must be connected only to a suitable elec-

trical supply and a suitable ground point. As such,

the plug must be plugged into an outlet that is properly grounded. Failure to connect the motor to ground may result in deadly electrical shock.

Page 15

page 15 of 121

The supply cable may be tted with a molded Europe-

an IEC plug or a plug suitable for your local electrical supply. The cable contains wires color coded as follows: green or green and yellow: ground; blue or white: neutral; brown or black: hot.

+ Due to the high compression ratio, the pump may gen-

erate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust pipeline or exhaust valve) at the outlet.

+ Do not permit any uncontrolled pressurizing. Make

sure that the exhaust pipeline cannot become blocked. If there is an exhaust isolation valve, make sure that you cannot operate the equipment with the valve closed to avoid a risk of bursting!

+ Maximum permissible pressure at the pressure trans-

ducer: 21.8 psi (1.5 bar) absolute.

+ Keep the electrical power cord away from heated sur-

faces.

• Provide a rm, level platform for the equipment. Check

that the system which you are going to evacuate is

mechanically stable. Check that all ttings are secure.

Ensure a stable position of the pump without any mechanical contact other than the pump feet.

• Comply with maximum permissible pressures at in- let and outlet and with maximum permissible pres- sure differences between inlet and outlet. See section „Technical data“, pg. 27. Do not operate the pump with overpressure at the inlet.

• Avoid overpressure of more than 17.5 psi absolute (1.2

bar absolute) in the event that inert gas is connected to the pump, to the gas ballast or to a venting valve.

• Note: Flexible elements will shrink when evacuated.

• Connect hoses gas tight at inlet and outlet of the pump.

Page 16

page 16 of 121

• Ensure that no foreign objects can be drawn into the

pump.

• Check the power source and the pump’s rating plate

to be sure that the power source and the equipment match in voltage, phase, and frequency.

• Ensure that the coolant outlet pipe is always free and that it cannot get blocked. If installing an optional coolant valve, it must always be in the supply line of the exhaust waste vapor condenser.

NOTICE

Make sure ventilation is adequate to maintain recommended operating temperature. Keep a minimum distance of 2 in (5 cm) between the cooling fan and surrounding items (e.g., housing, walls, etc.), or else install an external automatic ventilation system. Clean ventilation slots if necessary to avoid a reduction of ventilation. Do not place the pumping unit on soft surfaces (e.g., rubber foam) during operation. This may reduce or block the electronics’ air supply. Do not cover the pumping unit.

Use only hoses at the inlet and outlet of the pump with an inner diameter at least as large as the diameter of the pump’s tubing (to avoid overpressure at the outlet, and reduction of pumping speed at the inlet).

Allow the equipment to equilibrate to ambient temperature if you bring it from cold environment into a room prior to operation. Notice if there is water condensation on cold surfaces.

Secure coolant hoses at the hose nozzles (e.g., with hose clamp) to prevent their accidental slipping.

Comply with all applicable and relevant safety require-

ments (regulations and guidelines). Implement the required actions and adopt suitable safety measures.

Ambient conditions

➨ Do not reach for this product if it has fallen into liquid.

There is a risk of deadly electrical shock. Unplug the system immediately.

+ Do not use this product in an area where it can fall or

be pulled into water or other liquids.

• Adopt suitable measures in case of differences from

recommended conditions, e.g., using the equipment outdoors, installation in higher altitudes, conductive pollution or external condensation on the pump.

• Do not operate this product near ames.

NOTICE

To the best of our knowledge the equipment is in compliance with the requirements of the applicable EC-directives and harmonized standards (see ”Declaration of Conformity”) with regard to design, type and model. Directive EN 61010-1 gives in detail the conditions under which the equipment can be operated safely (see also IP degree of protection, „Technical data“, pg. 27).

Operating conditions

➨ These pumps are not approved for operation in po-

tentially explosive atmospheres. Do not operate the pumps in potentially explosive atmospheres.

➨ Pumps without the ”

not approved for the pumping of potentially explo-

” mark on the rating plate are

sive atmospheres. Do not pump potentially explosive atmospheres with those pumps.

➨ Pumps bearing the ”

mospheres (see section „ Equipment marking (ATEX)“, pg. 25).

➨ The pumps are not suitable to pump any of the sub-

stances listed below.

Do not pump:

- unstable substances

- substances which react explosively under impact (mechanical stress) without air

- substances which react explosively when being exposed to elevated temperatures without air,

- substances subject to auto-ignition,

- substances which are inammable without air

- explosive substances.

➨ The pumps are not approved for operation below

Important information:

ground. Do not operate the pump below ground.

• Do not pump substances which may form depos- its inside the pump. The pumps are not suitable for

pumping substances which may form deposits inside the pump. Deposits and condensate in the pump may lead to increased temperatures even to the point of exceeding the maximum permitted temperatures.

• Check the inlet and outlet of the pump, if there is a

danger of forming deposits inside the pump, e.g., in the pump chambers (the pump chamber is the part between diaphragm and head cover. See section „Replacing diaphragms and valves“, pg. 99). Inspect the pump chambers regularly and clean if necessary.

• Consider interactions and chemical reactions of the pumped media. Ensure that the materials of the

pump’s wetted parts are compatible with the pumped substances, see section „Technical data“, pg. 27.

When changing the substances pumped, we recom-

mend purging the pump with air or inert gas prior to changing the pumped media. Purging the pump will pump out residues and it will reduce the possibility of

Page 19

page 19 of 121

reactions of the pumped substances with each other and with the pump’s materials.

Safety during operation

➨ Adopt suitable measures to prevent the release of dan-

gerous, toxic, explosive, corrosive, noxious or pollut-

ing uids, vapors and gases. To prevent any emission

of such substances from the pump outlet, install an appropriate collecting and disposal system and take protective action for pump and environment.

➨ You must take suitable precautions to prevent any for-

mation of explosive mixtures in the pump chamber or at the outlet of the pump. In case, e.g., of a diaphragm failure, mechanically generated sparks, hot surfaces or static electricity may ignite these mixtures. Use inert gas for gas ballast or venting, if necessary.

➨ Drain appropriately or otherwise remove any poten-

tially explosive mixtures at the outlet of the pump, or dilute them to non-explosive concentrations.

➨ Never operate this pump if it has a damaged cord or

plug.

+ If the pump is not working properly, has been dropped

or has fallen into water, contact your pump service provider.

+ Prevent any part of the human body from coming into

contact with vacuum.

+ Make sure that the exhaust pipeline cannot become

blocked.

+ Check the overpressure safety relief device at the ex-

haust waste vapor condenser at appropriate intervals.

+ Avoid clogging of the exhaust vapor condenser caused

by deposits or freezing solvents.

(1060 mbar) the pressure reading becomes incorrect due to saturation of the pressure transducer. The dis-

play ashes. Release pressure immediately! Risk of

bursting!

+ Comply with applicable regulations when disposing of

chemicals. Take into consideration that chemicals may be contaminated. Take adequate precautions to protect people from the effects of dangerous substances (chemicals, thermal decomposition products of uoroelastomers). Use appropriate protective clothing and safety goggles.

+ Interruption of the pump (e.g., due to power failure),

failure of connected components or of parts of the supply, or change in parameters must not be allowed to lead to dangerous conditions. In case of a diaphragm failure or in case of a leak in the manifold, pumped substances might be released into the environment or into the pump housing or motor.

Comply with all notes regarding proper use of the

pumps, as well as operation and maintenance guidance.

+ The residual leak rate of the equipment might render

possible an exchange of gas, albeit extremely slight, between the environment and the vacuum system.

Adopt suitable measures to prevent contamination of

the pumped substances or the environment.

+ Cold surfaces can absorb a great amount of gas, which

may expand abruptly in case of warming. This may lead to unmanageable overpressure in the system, creating a risk of bursting!

+ Check the coolant level of the condenser at appropri-

ate intervals.

+ Attention: Coolant may overow unexpectedly, e.g.,

in case of large amounts of gas.

Page 21

page 21 of 121

+ Do not overll the condenser. Lowest permissible cool-

ant temperature: -112°F (-80°C).

+ Maximum operating pressure: 16 psi (1.1 bar) absolute.

• Ensure that no parts of your clothing, hair or ngers

can be caught or drawn in at the inlet of the pump.

Never insert ngers or drop any other object into the

inlet or outlet.

• Pumping at high inlet pressure may lead to overpressure at the gas ballast valve. Pumped gases or condensate might be expelled if the valve is open. If an inert gas supply is connected to the gas ballast, ensure that its inlet pipeline is not contaminated.

• You must take suitable precautions to prevent any

dangerous situation from arising if the controller starts the pump, switches a coolant valve or opens a venting valve.

• Attention: If the controller is set to Autostart, the pro- cess will start immediately after a power failure without pressing any further key. It is your responsibility to ensure that automatic start-up of the system will not lead to any dangerous condition. Provide appropriate safety measures. Check prior to starting the process whether the option ”Autostart” (menu: conguration) is enabled.

• Pay attention to the safety symbol ”hot surfaces” on the equipment. Hot parts may cause burns if touched. Adopt suitable measures to prevent any danger arising from hot surfaces or electric sparks. Ensure that hot surfaces of the pump do not cause burns. Provide a suitable contact guard if necessary.

• Ensure that the coolant outlet pipe at the waste vapor condenser is always free and that it cannot get blocked.

• Comply with all applicable safety measures and requirements when using cryogenic coolants (e.g., dry ice).

Attention: Coolant media may cause severe frostbite

when coming in contact with skin!

• Prior to every use: Inspect the condenser for faults.

There must be no damage on the glass surface. Do not use damaged components.

• Use only transport receptacles intended for coolants.

• Wear safety glasses and protective gloves.

• Do not clamp the covers of condensers or coolant re-

ceptacles. Allow pressure equalization between coolant and atmosphere.

NOTICE

Prevent the backpressure of gases and the backow of

condensates at the outlet.

Check the liquid level in the catchpots regularly and drain

condensate in time to prevent overlling. Install a level

sensor (see „Accessories“, pg. 94) for monitoring, if necessary.

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.

The CVC 3000 controller is powered by a short-circuitproof wide-range power supply with integrated overload protection. A temperature sensor at the circuit board protects the motor: Current limitation in case the temperature at the circuit board raises above 158°F (70°C). At temperatures above 185°F (85°C) the pump is switched off. In case of a motor blockage (after 10 start-up attempts) the pump is switched off. Note: Only manual reset is possible. Disconnect the pump from the power source. Identify and eliminate the cause of failure.

Maintenance and repair

NOTICE

In order to comply with laws (occupational, health and safety regulations, safety at work law and regulations for environmental protection) vacuum pumps, components and measuring instruments can only be returned when certain procedures (see section „Repair - Maintenance - Return - Calibration“, pg. 113) are followed.

Take advantage of our service seminars, which put special focus on the maintenance and repair of vacuum pumps. For details and for the online ”Instructions for repair” manual see www.vacuubrand.com.

In normal use, the lifetime of the diaphragms and valves is typically 15,000 operating hours. Bearings have a typical durability of 40000 h.

➨ Ensure that the pump cannot be operated acciden-

tally. Never operate the pump if covers or other parts of the pump are disassembled.

➨ Switch off the pump. Disconnect the electrical

power cord and wait two minutes before starting

maintenance to allow the capacitors to discharge.

➨ Note: The pump may be contaminated with process

chemicals, which have been pumped during operation. Ensure that the pump 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.

+ Wear parts have to be replaced regularly. + Never operate a defective or damaged pump.

+ Vent the pump before starting maintenance. Isolate

Page 24

page 24 of 121

the pump and other components from the vacuum sys-

tem. Allow sufcient cooling of the pump. Separate the

pump from the coolant circuit and drain condensate, if applicable.

NOTICE

Ensure that maintenance is done only by suitably trained and supervised technicians. Ensure that the maintenance technician is familiar with the safety procedures which relate to the products processed by the pumping system. Only dismantle the pump as far as necessary.

Important information: Equipment marking (ATEX)

VACUUBRAND equipment bearing mark (see rating plate)

II 3G IIC T3 X

Internal Atm. only

Tech. File Ref.: VAC-EX01

The classication 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).

The overall category of the equipment depends on the connected com-

ponents. If the connected components do not comply with the classication of the VACUUBRAND equipment, the specied 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 so that they are protected against

shocks from the outside and against glass splinters in the event of breakage (implosion).

Page 26

page 26 of 121

• 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 permissible. 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 specied ultimate vacuum is the pump’s leak rate 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 user must not operate the device if he does not understand this manual. In this case a technically correct translation of the complete manual has to be available. The manual must be completely read and understood before opera-

tion of the device. All specied measures

must be applied, or else must be replaced by equivalent measures at the user’s own risk.

Use and operation

When switching on the controller CVC 3000 for the very rst time, a menu

to select the language of the controller menu is displayed. Select the desired language (e.g., ”English”) by turning the selection knob and press

to conrm. Then select the pressure unit (”mbar”, ”Torr” or ”hPa”) in the

same way.

It is possible to access the language selection menu at any time by switching on the controller while keeping the selection knob pressed.

Installing a pump in a vacuum system

➨ If dangerous or polluting uids could be released at

the outlet, install an appropriate system to catch and

dispose of those uids.

+ Connect a gas-tight exhaust line at the pump outlet if

necessary. Always vent exhaust gases appropriately (e.g., into a fume hood).

+ Never block the gas outlet. The exhaust line must al-

ways be free of obstructions (no back pressure) to ensure an unimpeded discharge of gas. The cross-section of the outlet tubing must be at least the size of the pump’s exhaust connection.

+ Maximum permissible pressure: 21.8 psi (1.5 bar) ab-

solute.

+ Attention: At pressures above approximately 795 Torr

(1060 mbar) the pressure reading becomes incorrect due to saturation of the pressure transducer. The dis-

play will ash. Release pressure immediately! Risk of

bursting!

+ Particles and dust must not be aspirated. If necessary,

you must install appropriate lters. You must ensure their suitability concerning gas ow, chemical resis-

tance and resistance to clogging prior to use.

Page 39

page 39 of 121

+ Make sure ventilation is adequate, especially if the pump

is installed in an enclosure, or if the ambient temperature is elevated. Provide external ventilation, if necessary.

• Reduce the transmission of vibration. Prevent mechanical load due to rigid pipelines. Insert elastic hoses or

exible elements as couplings between the pump and

rigid pipes.

Note: Flexible elements will compress or atten when

evacuated if not designed for use under vacuum.

• Hose connections at the pump inlet must always be

gas tight.

NOTICE

• A power failure may cause accidental ventilation of the

pump, especially if the gas ballast valve is open. If this constitutes a potential source of danger, take appropriate safety measures.

• Check the power source and the pump’s rating plate

to be sure that the power source and the equipment match in voltage, phase, and frequency.

The ON/OFF switch is at the left side of the pumping unit. After switching off the pump, wait minimum 60 sec. before switching on again.

Use connecting hoses with large diameter and keep them

as short as possible to avoid ow losses. Locate the pump

as closely as possible to the application.

Always install outlet tubing descending from the pump or

provide other measures to avoid backow of condensate

towards the pump.

Page 40

page 40 of 121

Use a suitable valve to isolate the pump from the vacuum application. This is to allow the pump to warm up before pumping condensable vapors and to clean the pump after use before it is switched off.

When assembling, ensure vacuum-tightness. After assembly, check the whole system for leaks. Secure hose connections at the pump appropriately, e.g., with hose clamps, to protect against accidental detachment. To reduce pump noise emanating from the pump exhaust port, connect an exhaust hose or use a silencer (see „Accessories“, pg. 94).

The VACUUBRAND controller CVC 3000 can only be operated with components compatible with the VACU-

UBRAND VACUU•BUS system, (see „Accessories“, pg.

94). The vacuum controller CVC 3000 controls VACUUBRAND diaphragm pumps NT VARIO and VARIO-B, pumping units PC 30xx VARIO, and optional coolant and venting valves. Connected components (e.g., venting valve, level sensor, external pressure transducer 3000 series) are au-

tomatically identied and congurated. Identical compo- nents must be congurated beforehand; information upon

request.

Do not use more than one controller within the same

VACUU•BUS system. Several controllers in the same VACUU•BUS system

will interfere with each other and result in error messages of the connected components (pumps, valves).

CVC 3000

The CVC 3000 is equipped with an internal capacitive pressure transducer with ceramic diaphragm. It measures the actual pressure independently of the gas type, and with reference to the vacuum, i.e., absolute.

Page 41

page 41 of 121

- Condensate and deposits will affect the mea-

measurement connection at CVC 3000

surement results. Clean the pressure transducer, if necessary. See section „Cleaning the pressure transducer“, pg. 83.

Connecting components at the controller:

At the rear side of the controller are connections for e.g., an optional coolant valve and/or an external pressure transducer and/or an external venting valve, as well as a venting connection and the serial interface RS 232C.

- Pull the controller out of the housing. Be careful not to disconnect the measuring connection (PTFE tube)!

- Insert the cable of the component to be connected underneath the housing and plug into the controller. Do not apply off-axis forces when assembling or removing plug connections! Observe correct orientation of the plug.

- Insert controller into the housing.

Separator at inlet and exhaust waste vapor condenser:

Assembling the hose nozzle with union nut:

➨ Take the hose nozzle with attached compression fer-

rule and union nut out of the catchpot and put onto inlet connection.

➨ Tighten the union nut by hand until you can feel the

stop. Then tighten an additional 1/4 rotation with an

open-ended wrench (size 17mm) for nal installation.

Page 42

page 42 of 121

Catchpots:

catchpot at the inlet (10)

catchpot at the outlet (10)

The catchpot at the inlet protects against droplets and particles from entering the pump. + Enhances lifetimes of diaphragms and

valves.

+ Improves vacuum performance in applica-

tions with condensable vapors. Both catchpots are coated with a protective layer to protect against shattering in case of breakage or implosion. ➨ Assemble the catchpots at the inlet and at

the outlet using joint clips.

Exhaust waste vapor condenser (PC3001 VARIO

➨ Assemble the hose nozzles for coolant inlet

(11) and coolant outlet (12) tubing and for

the gas outlet (6) at the exhaust waste va-

por condenser.

The exhaust waste vapor condenser enables an efcient condensation of the pumped vapors at the outlet.

+ No backow of condensates. + Controlled recovery of condensates. + Close to 100% solvent recovery. + The isolation cover protects against glass splinters in

case of breakage, acts as thermal insulation to avoid condensation of humidity and is intended to absorb shocks.

➨ Attach the tubing of the coolant circuit to the respective

hose nozzles (hose nozzles for tubing I.D. 1/4”-5/16” (6-8 mm), see image) at the waste vapor condenser.

NOTICE

Check all hose connections prior to starting operation of the cooling system. Secure coolant hoses at the hose nozzles (e.g., with hose clamps) to prevent their accidentally slipping off.

Page 43

page 43 of 121

➨ Prevent the discharge of dangerous gases and vapors

to the surrounding atmosphere. If appropriate, connect the exhaust line to a suitable treatment system.

+ Never block the gas outlet ((8) hose nozzle for tubing

I.D. 3/8” (10 mm)). The exhaust hose has always to be unobstructed and without back pressure to enable an unhindered discharge of gases and protect the pump valves from damage.

• Note: Install the hoses of the cooling system in a way

to avoid the ow / dripping of condensed water onto the

pumping unit (especially cables and electronic parts, see also IP degree of protection, „Technical data“, pg.

27.

• Ensure that the coolant outlet tubing is always unob- structed and that it cannot get blocked.

• Maximum permissible coolant pressure at the exhaust

waste vapor condenser: 87 psi (6 bar) absolute. Outlet

ow must always be unhindered.

• Comply with the maximum permissible coolant pres-

sures of additional components in the coolant circuit (e.g., coolant valve).

• Avoid overpressure in the coolant circuit (e.g., caused

by blocked or squeezed coolant hoses).

• Only install the optional coolant valve in the supply line

of the exhaust waste vapor condenser.

➨ Adopt suitable measures to prevent the release of

dangerous, toxic, explosive, corrosive, noxious or polluting uids, vapors and gases when disposing of condensates.

+ Cold surfaces can absorb a great amount of gas, which

may expand abruptly in case of warming. This may lead to unmanageable overpressure in the system, creating a risk of bursting!

+ Check the coolant level of the condenser at appropri-

ate intervals.

+ Attention: Coolant may overow unexpectedly, e.g.,

in case of large amounts of gas.

+ Do not overll the condenser. Lowest permissible cool-

• Prior to every use: Inspect the condenser for faults.

There must be no damage on the glass surfaces. Do not use damaged components.

• Use only transport receptacles intended for coolants.

• Use safety glasses and protective gloves.

• Do not clamp the covers of condensers or coolant re-

ceptacles. Allow pressure equalization between coolant and atmosphere.

• Comply with all applicable safety measures and requirements when using cryogenic coolants.

➨ Remove cap. Fill coolant into the coolant

chamber. Put cap back in place. Do not clamp the cap.

+ Check coolant level at appropriate intervals. ➨ Check level of condensate at appropriate

intervals and drain condensate if necessary.

+ Wait until the condensate has liqueed, if

necessary.

+ Separate the inner part of the condenser

inner part of condenser

from the vacuum installation to drain the coolant.

➨ Remove the cap on top of the condenser.

Turn the inner part of the condenser and lift to pull it out. Comply with regulations when disposing of chemicals.

+ When reassembling check for the correct

position of the seal between inner and outer parts of the condenser.

Notes concerning the operation of the inlet condenser IK

+ Attention: The inlet condenser has no overpressure

safety relief device.

• Note: Install the hoses of the cooling system in a way to avoid the ow / dripping of condensed water onto the

pumping unit (especially cables and electronic parts), or use thermally insulated hoses to prevent condensation.

Page 46

page 46 of 121

• Ensure that the coolant outlet tubing at both con- densers is always unobstructed and that it cannot get blocked.

• Water pressure shock at the condensers may cause

breakage of the condenser coil!

Notes concerning the operation of the Peltronic emission condenser

NOTICE

Read the manual of the Peltronic emission condenser and observe the instructions contained in that manual!

Assembling the Peltronic emission condenser:

➨ Assemble the Peltronic emission condenser

with two attachment screws (Phillips screw-

(a)

(b)

(c)

driver size 2) to the pumping unit (a).

➨ Assemble the hose connection between

pump outlet and condenser inlet (b).

➨ Slip connecting tube onto hose connection

of the Peltronic emission condenser. Secure with hose clip.

➨ Connect the VACUU•BUS cable from the

CVC 3000 controller to the Peltronic emis-

NOTICE

sion condenser (c).

Notes concerning the operation of pumping units with silencer

Attention: Dust-laden gases, deposits and condensed

solvent vapor can restrict air ow out the silencer. The resultant back pressure can lead to damage of pump bearings, diaphragms, and valves. Under those conditions, a silencer must not be used.

Page 47

page 47 of 121

During operation

➨ Vent and dispose of potentially dangerous gases or

vapors at the outlet of the pump appropriately.

+ Due to the high compression ratio, the pump might

generate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust tubing or exhaust valve) at the outlet. Ensure that the pump outlet is neither blocked nor restricted.

+ Maximum ambient temperature: 104 °F (40 °C) Check the maximum temperatures, if installing the

pump in a cabinet or a housing. Make sure ventilation

NOTICE

is adequate, especially if the ambient temperature is elevated.

• If the pump is installed at an altitude of more than 6500

ft (2000 m) above mean sea level, check compatibility with applicable safety requirements, and adopt suitable measures. There is a risk of the motor overheat-

ing due to insufcient cooling.

• Check compatibility with the maximally permitted

pressure at outlet and the maximum pressure difference between inlet and outlet ports.

Do not start the pump if the pressure difference between inlet and outlet ports exceeds max. 16.0 psi (1.1 bar).

Attempts to start the pump at higher pressure difference may cause stalling and damage of the motor.

If pumping condensable vapors (water vapor, solvents, etc.), let the pump run with gas ballast to help purge any condensation in the pump.

Prevent internal condensation, transfer of liquids or dust. The diaphragms and valves will be damaged, if liquids are

pumped in signicant amounts.

Check the pump regularly for external soiling and deposits.

Page 48

page 48 of 121

Clean the pump if necessary to avoid an increase of the pump’s operating temperature.

Operation with silencer (optional) at the outlet: Operating the pump at a high inlet pressure or pumping dusty gases for a long time may cause clogging of the silencer. Check the silencer regularly and replace if necessary.

A temperature sensor at the circuit board protects the motor: Current limitation in the event the temperature at the circuit board raises above 158°F (70°C). At temperatures above 185°F (85°C) the pump is switched off. In the event of a motor blockage (after 10 start-up attempts) the pump is switched off. Note: Only manual reset is possible. Disconnect the pump from the power source. Identify and eliminate the cause of failure.

Check ventilation slots regularly for dust/dirt. Clean if necessary. Avoid overheating (e.g., due to hot process gases).

A warm up period (approximately 15 min.) is required to ensure that the rated ultimate vacuum and pumping speed are attained.

Important notes regarding the use of gas ballast

Gas ballast is a continuous purge to keep the pump’s interior as clean as possible and to reduce the possibility of condensation inside the pump.

➨ Air and pumped media might react inside the pump or

at the outlet of the pump and form hazardous or explosive mixtures, when you use air rather than inert gas

for the gas ballast. This constitutes a risk of signicant

damage to equipment and/or facilities, a risk of personal injury or even loss of life.

Page 49

page 49 of 121

+ Make sure that air/gas intake through the gas ballast

valve can never lead to hazardous, explosive or otherwise dangerous mixtures. If in doubt, use inert gas.

NOTICE

To reduce condensation in the pump, do not pump vapor before the pump has reached its operating temperature. Open the gas ballast valve when pumping condensable vapors. Turn gas ballast cap to open valve.

For condensable vapors (water vapor, solvents, etc.):

- The gas ballast valve is open if the arrow on the gas ballast cap is pointing towards the

gas ballast

pump.

- With gas ballast valve open, the ultimate vacuum will be reduced.

- Use inert gas for gas ballast to avoid the formation of explosive mixtures. Attention: maximum supply pressure of inert gas: 17.5 psi (1.2 bar) absolute.

- Close the gas ballast valve by turning the cap 180°.

In case of low boiling solvents (when the formation of condensate is unlikely), the use of gas ballast might be unnecessary. Operating the pump without gas ballast increases the solvent recovery rate at the exhaust waste vapor condenser.

Important notes concerning the operation of the exhaust waste vapor condenser

➨ Connect the exhaust to a suitable treatment system to

prevent the discharge of dangerous gases and vapors to the surrounding atmosphere.

+ Never block the gas outlet ((6) hose nozzle for tubing

I.D. 3/8” (10 mm)). The exhaust hose must always be unobstructed and without back-pressure to enable an unhindered discharge of gases.

+ Check the overpressure safety relief device (17) at the

Page 50

page 50 of 121

exhaust waste vapor condenser (9) regularly; replace if necessary. Check especially for deterioration, coalescence and cracks.

• Ensure that the coolant outlet hose is always free and that it cannot get blocked.

• Maximum permissible coolant pressure at the exhaust

waste vapor condenser: 87 psi (6 bar) absolute

• Comply with the maximum permissible coolant pressures of additional components in the coolant circuit (e.g., coolant valve).

• We strongly recommend installing an optional coolant

valve (see „Accessories“, pg. 94) in the supply line of the exhaust vapor condenser to save water and re-

NOTICE

duce the risk of water spill.

• Avoid overpressure in the coolant circuit (e.g., caused

by blocked or kinked coolant hoses).

• Avoid any clogging of the exhaust vapor condenser

caused by deposits or frozen solvents. Clean if necessary or use higher coolant temperatures.

In case of condensation: Check the liquid level in both catchpots (10) during operation. Check the liquid lev-

el regularly. Do not allow the catchpots to overll. Drain catchpots in time to avoid overow. Install a level sensor

(see „Accessories“, pg. 94) for monitoring, if necessary. The maximum liquid level is at approximately 80% of the

total lling level to avoid problems when removing the

catchpots.

Permissible range of coolant temperature at the exhaust waste vapor condenser: 5 °F to 68 °F (-15°C to +20°C)

Check hose connections prior to starting operation of the cooling system. Check coolant hoses regularly during operation.

Removing the catchpots:

Stop process.

Page 51

page 51 of 121

Catchpot at outlet: Remove joint clip. Remove catchpot and drain condensate. Catchpot at inlet: Admit air or inert gas (via the pump inlet) to restore atmospheric pressure in the catchpot before attempting removal. Remove joint clip. Remove catchpot and drain condensate.

NOTICE

Reattach drained catchpots.

+ Important: Comply with regulations when disposing

of solvents/condensates. Recycle if possible; purify if contaminated.

Shutdown & storage

The pump can be switched off under vacuum.

Short-term:

Has the pump been exposed to condensate?

- Allow the pump to continue to run at atmospheric pressure for a few minutes.

Has the pump been exposed to media which may damage the pump materials or form deposits?

- Check and clean pump heads if necessary.

Has the pressure transducer been exposed to media which may form deposits?

- Clean pressure transducer at the CVC 3000 controller if necessary.

Long-term:

- Take measures as described above regarding shortterm shutdown.

- Separate the pump from the application.

- Close inlet and outlet ports (e.g., with transport caps).

- Close the gas ballast valve.

- Drain catchpots.

- Store the pump under dry conditions.

Notes on selecting the function

The CVC 3000 controller can be adapted to the specic application by

choosing the appropriate function depending on the connected components and the requirements of the application.

Automatic detection of the components

When switching on the controller, the conguration of the connected components is checked automatically.

Connected components (e.g., VACUU•BUS-compatible VARIO pumps, gauge heads 3000 series, valves, level sensors) are detected automatically and controlled by the CVC 3000 until the controller is switched off.

Identical components must be congured beforehand; information upon request. Switch the controller off and on again to renew the conguration.

The last mode of operation and the preselected values (e.g., for pressure, speed or time for automated switching off) are stored. If the preselections are chosen appropriately, it is possible to start immediately if similar operating conditions are desired.

The controller features ve functions and one conguration menu, see section ”Menu guide”. Each of these functions involves different menu

options, which are presented automatically and reect the connected

components. The types of components connected (e.g., valves) determine the active menu items.

Changing the function:

➨ Switch controller on. ➨ Press ”START/STOP” key to terminate control in case control is run-

ning (e.g., if ”Autostart” is activated).

➨ Press ”MODE” key. ➨ Select function with knob and press to conrm.

Pump down function

Function denition:

➨ Continuous pumping with pressure and time settings

• Operation on demand of a speed controlled VACUU•BUS-

compatible VARIO pump

Preselections

+ Use the selection knob to select the parameters. All parameters can

be altered even while operation control is running.

+ Speed: Preselection of the motor speed for pump down. The selec-

tion ”HI” effects the maximum speed and best ultimate vacuum of the pump (with automatic speed reduction at ultimate vacuum).

The ”Speed” is adjustable in a range of 1-100% and to ”HI”.

+ Minimum: The controller switches the pump off once the preset value

for ”Minimum” has been reached.

”Minimum” is adjustable in a range of 1-795 Torr (1-1060 mbar) or can

be set to ”Off”.

A preset ”Duration” (process time) has no effect if the process is

stopped due to a preset ”Minimum” before ”Duration” is reached.

+ Delay: ”Delay” determines the time the coolant valve remains open

after the process has been stopped.

The ”Delay” is adjustable in a range of 1-300 minutes or can be set to

”Off” (”Off” means that the coolant valve closes immediately when the process stops.).

+ Duration: ”Duration” determines the total process time since control

start.

The process time is adjustable between 1-1440 minutes (24 h) or can

be set to ”Off”. ”Off” indicates that no endpoint for pump down is determined.

If a ”Duration” is preset, the controller switches off the pump when the

preset process time is reached, even if a preset ”Minimum” is still not reached.

Vac Control function

Function denition:

➨ Vacuum control to a preset vacuum value

• Operation on demand of a speed controlled pump (VACUU•BUS-

compatible VARIO pump)

Preselections

+ Use the selection knob to select the parameters. All parameters can

be altered even while operation control is running.

+ Set vacuum: The ”Set vacuum” is the set point for vacuum control

with pinpoint precision for VACUU•BUS-compatible VARIO pumps.

The ”Set vacuum” is adjustable in a range of 1-795 Torr (1-1060 mbar)

or can be set to ”Turbo”. The selection ”Turbo” leads to the optimum backing pressure for a turbomolecular pump.

+ Speed: The maximum motor speed can be preselected (to control the

pumping speed).

The ”Speed” is adjustable in a range of 1-100% or can be set to ”HI”. The selection ”HI” (recommended) provides the optimum pumping

speed of the pump and therefore an optimum ultimate vacuum.

+ Maximum: An upper pressure limit can be preselected. The pump

switches off if the pressure limit is exceeded, e.g., at the end of suc-

tions or ltrations. The pressure limit is only active once the pressure

has gone below ”Maximum”.

The ”Maximum” is adjustable in a range of 794-1Torr (1059 - 1 mbar)

(at the least 1 Torr (mbar) higher than the ”Set vacuum”) and to ”Off”. ”Off” means that no ”Maximum” value is preset.

+ Delay: ”Delay” determines the time the coolant valve remains open

after the process has been stopped.

The ”Delay” is adjustable in a range of 1-300 minutes or can be set to

”Off” (”Off” means that the coolant valve closes immediately when the process stops.).

+ Duration: ”Duration” determines the total process time since control

start.

Page 62

Auto mode

Function denition:

➨ Control of a VACUU•BUS-compatible VARIO pump in ”Auto

mode”:

Automatic detection of boiling points, and automatic adjustment

of determined boiling points as process parameters change.

Preselections

+ Use the selection knob to set the parameters.

+ Sensitivity: The ”Sensitivity” of the control determines the control speed.

The ”Sensitivity” is adjustable to ”high”, ”normal” or ”low”.

High sensitivity leads to a reduced pump-down speed, e.g., for small

amounts of solvents or foaming processes. Use a low sensitivity for ”noncritical” processes to reduce process time. Usually setting the ”Sensitiv- ity” to ”normal” is appropriate.

+ Speed: The maximum motor speed can be preselected (to limit the

pumping speed).

The ”Speed” is adjustable in a range of 1-100% or can be set to ”HI”.

The selection ”HI” (recommended) causes an automatic limitation of the adaptation depending on parameters determined during the process. Only in case of very sensitive processes is it advisable to reduce the maximum speed.

+ Minimum: If the vacuum value reaches ”Minimum” the process is

stopped. Use ”Minimum” for automatic process termination.

The ”Minimum” is adjustable in a range of 2-795 Torr (2 - 1060 mbar),

or can be set to ”Auto” or to ”Off”.

When selecting ”Auto” the controller switches off automatically at the

end of the process (boiling plateau). This is recommended only for large amounts of solvents.

+ Delay: ”Delay” species the time the coolant valve remains open after

process stop.

The ”Delay” is adjustable in a range of 1-300 minutes or can be set to

”Off” (”Off” means that the coolant valve closes immediately when the process stops.).

Page 65

page 65 of 121

+ Duration: ”Duration” determines the total process time since control

start.

The ”Duration” is adjustable between 1-1440 minutes (24 h) or can

reach a preset vacuum level or, if programming a ”Step”, the runtime after having achieved the vacuum level. The total process runtime is shown in the base line. Attention: A preset runtime of 99:59:59 hours in the nal program step will cause the process to run endlessly. Terminate the process by pressing the ”STOP” key .

Vacuum: Vacuum level to be attained. Venting valve: Operating a venting valve to reach a preset vacuum

level.

”Step”: ”Step” causes pump down as fast as possible to the preset

vacuum level. As soon as the vacuum level is reached the time meter starts running.

”Auto”: Auto = ➜ : indicates that the system will search for a boiling

point automatically, and will automatically adapt to changes in the boiling point until a preselected time interval expires.

Auto = : indicates that the system will automatically adapt to chang-

es in the boiling point. The program step is nished when the selected

time or pressure value has been reached.

Selecting ”Auto” in combination with ”Step” in one program step is not

possible.

+ Open: Choose program (Programs 0 - 9).

+ Store: This command stores an edited program or the program of the

last process to one of the storage spaces 0 - 9.

+ Delay: ”Delay” species the time the coolant valve remains open after

➜

* If the pressure difference

between the vacuum for degassing and the expected vacuum for distillation is very small (distillation vacuum >75% of the degassing vacuum), select the function ”Auto ” (adapting the vacuum starting from the current pressure) in-

stead of ” Auto➜” (at rst searching the boiling point automatically, and then adapting the vacuum).

Program step 1 should be always a denite initial state, here atmospheric pressure (ATM). To reach this state denitely, set a tickmark at ”Vent.”

and ”Step” by pressing the selection knob. In step 2, pumping begins, attempting to reach 300 Torr/mbar as quickly as possible (”Step”). Vacuum holds there for 10 minutes (degassing the solvent).

In step 3, ”Auto ➜ ” causes an automatic search of a boiling point in the pressure interval between 300 Torr/mbar/hPa (depending on preset pressure unit) and 2 Torr/mbar/hPa, followed by automatic adaptation to changes in the boiling point. The following step starts either (1) once the cumulative process time reaches the set limit (1 hour/60 minutes), even if the preset pressure (2 Torr/mbar/hPa) has not been reached, or (2) if a vacuum of 2 Torr/mbar/hPa is reached, even if the preset time has not been completed. Step 4 vents to atmospheric pressure as fast as possible and switches off the control after one minute.

VACUULAN function

Function denition:

➨ Optimizes vacuum control for vacuum networks

(e.g., VACUUBRAND VACUU•LAN)

➨ Permits on-demand operation of a speed-controlled pump

(VACUU•BUS-compatible VARIO pump)

Preselections

+ Use the selection knob to select the parameters.

+ Set vacuum (the lower switch-off value): If the pressure drops below

the ”Set vacuum”, a time-meter starts to run and the motor speed is reduced. When the pressure exceeds the ”Set vacuum” pressure again, the time meter is reset. If the ”Set vacuum” is not reached within 100 hours, the controller signals an error.

The ”Set vacuum” is adjustable in the range of 1-795 Torr (1-1060

mbar).

+ Switch on (the higher switching value): If the pressure exceeds this

pressure, pumping down starts again.

The ”Switch on” pressure is adjustable in the range of 2-795 Torr (2-

1060 mbar).

In the event of a sudden high-pressure spike, pumping starts again

even if the ”Switch on” pressure has not been reached (pressure increase control).

+ Delay: If the vacuum is below ”Set vacuum” for longer than the ”Delay”

time, the pump is stopped. Pumping starts again in the event of a rapid pressure increase or if the ”Switch on” level is exceeded.

The ”Delay” is adjustable in a range of 1-300 minutes or can be set to

”Off” (”Off” means that the pump stops immediately when the pressure drops below ”Set vacuum”.).

Application examples

Assembly of a vacuum system

+ Assemble the vacuum connection line between the vacuum pump and

the vacuum application.

+ Assemble the vacuum connection line between the controller and the

vacuum application, if the controller is not part of a pumping unit.

+ Assemble electrical connections. + Connect coolant if necessary.

Vacuum for ltration and suction

+ Select ”Pump down” function. + If necessary, set value for ”Speed” (high or low pumping speed). Re-

duce the speed in case of fast sedimentation (formation of a lter cake).

+ Set ”Minimum” to a value which provides adequate suction but does

not lead to evaporation of the solvent.

+ Start process by pressing ”START/STOP” key.

alternatively:

+ Select ”Vac control” function. + Set ”Set vacuum” to a value which does not lead to evaporation of the

solvent.

+ If necessary, set value for ”Speed” (high or low pumping speed). Re-

duce the speed in case of fast sedimentation (formation of a lter cake).

+ Set ”Maximum” pressure setting so that pump will switch off at the end

of the ltration process, or in the event that a lter cake cracks, leading

to a sudden pressure increase.

+ Start process by pressing ”START/STOP” key.

+ Tip for ltration: Adjust preset pressure to a value well above the

boiling pressure of the solvent (e.g., for water >>15 Torr (20 mbar)).

Set the maximum pressure to e.g., 375 Torr (500 mbar). Once the ltration has nished, the pressure increases and the pump is switched

off automatically.

Vacuum for gel dryer, drying chambers and vacuum concentrators

+ Select function ”Pump down” function. ”Speed” ”HI” is recommended.

For gel dryers set a lower speed if necessary (if the gels tend to crack).

+ Set ”Minimum” to prevent volatile components from evaporating. The

process is stopped automatically as soon as ”Minimum” is reached.

+ Set a process time (”Duration”) if necessary. + Start process by pressing ”START/STOP” key.

alternatively:

+ Select ”Vac control” function to dry at a predetermined vacuum level. + Set ”Set vacuum” to the preferred evaporation vacuum of the solvent. + Set a process time (”Duration”) if necessary. + Start process by pressing ”START/STOP” key.

Vacuum for distillation and evaporation (e.g., rotary evaporator)

Fully automatic determination and adaptation of the boiling point

with a VACUU•BUS-compatible VARIO pump (recommended)

+ Select ”Auto mode”. + Start process by pressing ”START/STOP” key. + The ”Auto mode” allows a fully automatic distillation even if the boiling

vacuum is unknown. With solvent mixtures, the vacuum is reduced until all solvents or volatile components are evaporated (with respect to the ultimate vacuum of the pump and the bath temperature).

+ If ”Minimum” is set, the controller switches off the pump when the pre-

set vacuum value is reached. The ”Minimum” should be well below the boiling vacuum of the solvent to be evaporated and above the ultimate vacuum attainable in the apparatus. If the ”Minimum” is set to ”Auto” , the controller automatically switches off the pump at the end of the evaporation (recommended for large solvent quantities only). The setting of ”Duration” (process runtime) has no effect if the pump is switched off due to ”Minimum” before ”Duration” is over.

Page 73

page 73 of 121

+ When setting a value for ”Duration” the controller switches off the

pump when ”Duration” has passed even if a preset ”Minimum” is still not reached.

+ If neither ”Minimum” nor ”Duration” is preset, pumping down has to be

nished by pressing the ”START/STOP” key.

alternatively:

Semi-automatic distillation and evaporation

+ Select function ”Pump down”. + Start process by pressing ”START/STOP” key. + Observe process. As soon as evaporation starts, press ”MODE” key

(switching to ”Vac control”). The vacuum level is kept constant (at the boiling pressure). Fine tuning of the vacuum value is possible by turning the selection knob.

Pressing ”MODE” key a second time switches to ”Auto mode” causing

the vacuum level to be automatically adapted to changes of the boiling pressure.

alternatively:

+ Select ”Vac control” function. + Set a maximum ”Speed”, to select a faster or slower process. + To set ”Maximum” is usually not necessary, unlike ltrations, because

the pressure does not increase at the end of the evaporation.

+ Set a value for ”Duration” if the process should be terminated auto-

matically after a denite time.

+ Set ”Set vacuum” depending on the solvent and the temperature. + Start process by pressing ”START” key. + To temporarily switch to ”Auto mode”: Press ”MODE” key. The

controller switches to ”Auto mode”. The setting of the controller does not change due to this switching. After pressing ”START/STOP” key the controller is in ”Vac control” again.

Vacuum for VACUU•LAN networks

+ Select function ”VACUULAN”. + Set ”Set vacuum” to a pressure which can be reached reliably in the

vacuum network. Take account of the ultimate vacuum of the pump and of the system’s leak rate in case of no vacuum demand.

+ Set ”Switch on” pressure appropriately to ensure sufcient vacuum for

all connected applications.

+ Set ”Delay” if necessary. + Start process by pressing ”START/STOP” key.

Conguration

In the ”Conguration” menu the device parameters are preselected. After 20 seconds without action the function ”Conguration” and its sub-

menus (except submenu ”Sensors”) are quit automatically without storing any possibly changed parameter.

Preselections

+ Use the selection knob to select the parameters.

+ Adjustment: Adjustment of the pressure transducer under vacuum

and/or at atmospheric pressure, see also section „Readjustment of CVC 3000“, pg. 80.

Adjustment to atmospheric pressure is carried out at an absolute pres-

sure value between 795 - 525 Torr (1060 - 700 mbar). This is especially helpful in high elevation laboratories. Adjustment under vacuum may be done at an absolute vacuum value between 0 - 15 Torr (0 - 20 mbar). In the range between 15 to 525 Torr (20 to 700 mbar) no adjustment is possible; ---- Torr is displayed.

+ RS-232: Conguration of the interface, setting of parameters and com-

mands, see section ”Interface”.

Baud rate can be set to 19200, 9600, 4800 or 2400, parity on ”8-N-1”,

”7-O-1” or ”7-E-1”, Handshake on ”no”, ”Xon-Xoff” or ”RTS-CTS” and remote on ”On” or ”Off”.

+ Sensors: Selection of the pressure transducer to be controlled (maxi-

mum 4 external sensors).

+ Display: Selection of the device parameters ”Brightness” between 0

- 100%, ”Contrast” between 0 - 100%, ”Sound” ”On” or ”Off”, ”Units” ”mbar”, ”hPa” or ”Torr”, ”Language” ”German”, ”English”, ”French”, ”Italian”, ”Spanish”, ”Turkish”, ”Korean”, ”Chinese”, ”Portuguese”, ”Russian”, ”Polish”, ”Dutch”, ”Japanese”, ”Finnish”.

+ Autostart: If ”Autostart” is set to ”On” the controller restarts a running

process automatically after a power failure. If this is unwanted, set ”Autostart” to ”Off”.

Page 76

page 76 of 121

Attention: If ”Autostart” is preselected, the process starts

immediately after 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 startup can occur and to provide appropriate safety measures. If necessary, the user has to check prior to starting the process if the option ”Autostart” is enabled.

+ Defaults: If ”Defaults” is set to ”Load”, the controller is reset to factory

set values. All stored programs and parameters are deleted.

This screen-shot shows the factory-set values.
