2 Basic Safety Instructions

2.1 General Information

CAUTION !

Warning notices must be observed. Disregarding them may lead to damage to health and property.

The Laboratory-Vacuum-Systems must be operated by personnel who can detect impending dangers and take action to prevent them from materialising.

The user/operator is responsible for correct installation and safe operation. Prevent condensate collecting in the pump. When pumping vapours which tend to condense

please ensure that the pump is at operating temperature and that the gas ballast valve is open when the pump is switched on.

If there is more than one load on one LVS, they must be separated by check valves. After finishing work with the diaphragm pump, run it for about 10 minutes with an open gas

ballast valve. The manufacturer or authorized authorised workshops will only service or maintain the Labo-

ratory-Vacuum-System if it is accompanied by a fully completed damage report. Precise information about the contamination (also negative information if necessary) and thorough cleaning of the Laboratory-Vacuum-Systems are legally binding parts of the contract.

Contaminated Laboratory-Vacuum-Systems and their individual parts must be disposed of in accordance with the legal regulations.

The local regulations apply in foreign countries.

2.2 Electricity

The Laboratory-Vacuum-Systems are supplied for operating mode S1. Please note that the testing must be repeated in accordance with DIN EN 0105, DIN EN 0702 and BGV A2 in case of portable devices.

The local regulations apply in foreign countries.

Please note the following when connecting to the electrical power supply system:

The electrical power supply system must have a protective connector according to DIN VDE 0100-410 (IEC 60364-4-41).

The protective connector must not have any breaks. The connecting cable must not be damaged. All interfaces are under low voltage according to DIN VDE 0100-410.

Basic Safety Instructions

8 115041

2.3 Mechanical Systems

Improper use can lead to injuries or material damage. Observe the following instructions:

Only operate the Laboratory-Vacuum-Systems with hoses of the specified dimensions. The maximum permissible pressure of 1 bar at the suction connection must not be ex-

ceeded. Hazardous substances must be separated out as far as this is technically possible before

they reach the pump. External mechanical stresses and vibrations must not be transmitted to the pump. Only

use flexible laboratory hoses for connecting Laboratory-Vacuum-Systems. The overpressure generated at the pressure port must not exceed 1 bar. The pump must not be used to suck up fluids. Lay the exhaust pipe so that it slopes

downwards, so allowing condensate to flow out of the pump. Collect the condensate and dispose of it in an environmentally compatible manner.

CAUTION !

Solid particles in the pumping medium impair the pumping action and can lead to damage. Prevent solid particles penetrating into the pump.

When handling glass vessels, pay attention to:

Only use glass vessels with a plastic coating for splinter protection. Only use vessels which are suitable for use with vacuums (e.g. round-bottomed flasks).

We recommend that only glass components supplied by the manufacturer are used. Do not use Erlenmeyer flasks.

Before each evacuation, check glass vessels for damage which might impair their strength, replace them if any such damage is found.

Do not heat glass vessels on one side only. Retardation of the boiling of the gases to be pumped can lead to a sudden pressure in-

crease. Prevent retardation of boiling by means of suitable measures (e.g. turbulent agitation).

2.4 High Temperatures

The diaphragm pump may heat up as a result of the temperature of the gas being pumped and through compression heat. Prevent the following maximum permissible temperatures from being exceeded.

+ 40 °C for the environment, and + 60 °C for the gas to be pumped.

The motor for single phase alternating current is protected against overload by an integrated motor protection switch.

Basic Safety Instructions

115041 9

2.5 Hazardous Substances

The operating company bears the responsibility for the use of the Laboratory-VacuumSystem.

Hazardous and harmful substances must be effectively prevented from escaping. Ensure that all lines and connections are leak tight. Handle exhaust gases in accordance with the requirements of the emission protection regulations. Do not operate the Laboratory-Vacuum-System without a separator and without a emission condenser. The separator can only be emptied after the apparatus has been vented. Dispose the condensate in an environmentally compatible manner!

The emission condenser has a safety valve. The air evacuation duct with hose must be kept clear and lead into a suitable air evacuation duct. Throttling the air evacuation duct can damage the valves of the diaphragm pump.

Hazardous substances in the gases to be pumped can cause personal injuries and property damage. Pay attention to the warning notices for handling hazardous substances.

The local regulations apply in foreign countries.

Combustible Gases

Examine before switching on whether that can form gas combustible gas/air mixtures which can be promoted! Also perform this test with a number of loads connected to one LVS. Consider the regulations of the guideline 1999/92/EC.

Explosive gases The diaphragm pumps of the series MPC are certified according to ATEX guidelines

2014/34/EU, device category 3, valid for the gas contacting parts (interior) of the pump.

Aggressive gases

An MPC series diaphragm pump is used for extracting vapours and aggressive gases. The warranty shall lapse if the LVS is used with diaphragm pumps from other manufacturers. Especially aggressive gases have to be explicitly checked for material resistance as de-

scribed in chapter 3.1.2 and, if necessary, modified.

Poisonous gases

Use a separator when pumping poisonous or harmful gases. Prevent such substances from leaking out of the appliance or pump. Treat these substances according to the applicable environmental protection regulations.

The diaphragm pump, control valves and hose lines can be damaged by poisonous or aggressive gases.

Test the strength and leak-tightness of the connecting lines and the connected apparatus. Prevent environmental poisons, e.g. mercury, getting into the diaphragm pumps.

Fulfil the requirements, for example:

German Hazardous Substances Regulation (GefStoffV) of 01. December 2010 Regulations 2016/1179/EU (classification, packaging and identification of hazardous sub-stances), Manufacturer's safety data sheets on hazardous substances.

3 Description

3.1 Design and Function

3.1.1 Laboratory-Vacuum-Systems

The Laboratory Vacuum Systems are supplied as a ready-mounted unit. The chemical-resistant diaphragm pump (4) with gas ballast valve (17) is fitted to the base plate of the column (3) and attached on the suction-side to the separator (7) to protect the pump from foreign matter and on the pressure-side to the emission condenser (6) to recover the condensate. This ensures that hazardous substances are separated out. The safety valve on the emission condenser protects against an impermissibly high operating pressure on the outgoing air end. The complete vacuum controller, with sensor, venting valve and power unit (5), is fitted in the column (3). The LVS 310 Z ef, order no. 115244-04, is an exception. In this case, the vacuum controller is available as an external device for installation in laboratory furniture, see chapter 3.1.4. The manually regulated LVS-variant does not have a controller. All exposed glass components (6, 7) are coated with transparent plastic as protection against bursting. The emission condenser is supplied with insulation.

The power switch (12) and the plug for the power cable (11) as well as the membrane pump (10), the PC (13) control lead (14), inert gas (16) and the water valve (option) (15) are located on the right of the column. The LVS types are specially preconfigured according to model.

3.1.2 Diaphragm pump

► Design:

The diaphragm pump consists of a pump body and a drive motor. The pump body consists of a drive shaft and two pump heads. Both pump head contains a diaphragm and the work valves. The two pump heads are arranged opposite each other.

In the two-stage (Z) diaphragm pump, both pump heads are connected in series. The pump heads are driven via an eccentric shaft with a connecting rod.

► Function:

Motor, eccentric shaft and connecting rod set the diaphragms in stroke movement. This changes the size of the space between the diaphragms and pump head (pump chamber).

Increasing the size of the pump chamber opens the inlet valve while the outlet valve is closed (intake process). Decreasing the size of the pump chamber ejects the gas through the outlet valve.

The valves are actuated by the gas being pumped. A large proportion of fluid in the diaphragm pump minimizes the pumping efficiency.

► Materials of the medium-affecting pump parts:

Material resistance to aggressive media see: Publisher Hoppenstedt Publishing (18. September 2007)

► Gas ballast:

When condensable vapours are pumped, they may be compressed above the saturated vapour pressure and condense.

Opening the gas ballast valve (17) in the suction line of the last pump stage allows air to flow into the pump chamber. This prevents condensation and flushes the pump clear.

Operation leads to increasing the ultimate pressure and the operating temperature.

CAUTION !

The economic Laboratory Vacuum System "LVS ... en" is suitable for slow processes and central laboratory supplies using a large hysteresis (< 50 mbar). When installing the switch interval of the diaphragm pump is to be checked. In practical applications the time-out must be at least 0.5 minutes. The integrated pressure monitor guarantees immediate activation of the vacuum generator when required. This ensures continuous readiness of the vacuum system in the laboratory.

5 Assembly and Installation

5.1 Unpacking

Carefully unpack the Laboratory-Vacuum-System.

Check the system for:

Transport damage, Conformity with the specifications of the supply contract (type, electrical supply data), Completeness of the delivery.

Please inform us without delay if there are discrepancies between the delivery and the contractually agreed scope of delivery, or if damage is detected. Please take note of the general terms of business of the manufacturing firm.

In case of a claim under warranty, the device must be returned in packaging that is suitable for protecting it during transport.

5.2 Installation and Connection

Set the Laboratory-Vacuum-System on a flat and horizontal surface. Remove the protective caps on the connections. Connect the intake connector of the LVS to your apparatus with vacuum hose DN 8. Connect the cooling water tube to the emission condenser. The cooling water return flow must be unpressurized. Connect the air exhaust to the central air exhaust system. Connect the Laboratory-Vacuum-System to the power supply. Check that the connections are properly seated.

5.3 General instructions

Observe the basic safety instructions when using the LVS.

The pressure device regulation 2014/68/EU must be observed if devices with an overpressure of 0.5 bar or more are connected.

The pressures at the intake and exhaust sides of the diaphragm pump at the time it is switched on must correspond to the specifications of DIN 28432.

In order to avoid pumping speed losses, all the vacuum connecting hoses used should have a large nominal diameter and should be laid out so that the lengths are as short as possible. Avoid rigid connections. They must be assembled carefully in order to achieve a low leak rate.

We recommend fitting non-return valves (order no. 720327) for applications with several consumers.

The upstream separator on the intake-side serves to protect the diaphragm pump and the vacuum sensor from condensates and mechanical contamination. It must be used for an application. The level in the separator must be monitored and the separator emptied regularly. The currently valid regulations must be observed when disposing of waste. The separator on the intake-side can only be removed and emptied after the system has been vented.

Assembly and Installation

115041 23

The emission condenser enables a 100 per cent recovery of the solvents led through the vacuum pump. Cooling takes place via the DN 8 hose nozzles. Ensure that the outflow is clear. The safety valve is located at the gas inlet. The rubber valve seal must be checked for cracks at regular intervals and exchanged when necessary. The exhaust connection is unpressurized. It can be led off through a DN 10 hose into a suitable evacuation duct. There is common solvent reclamation for all the connected systems. Mixing media must not lead to a hazard for persons, the environment of for the equipment.

Condensable vapours may only be extracted when the pump is at operating temperature. When doing so, the gas ballast valve should be opened and/or a quantity of air, which is to be calculated by the user, allowed to enter via the intake port valve. The pressure values may be increased when doing so. The diaphragm pump's maximum tolerance of water vapour pressure can be improved or a cleaning run can be made after finishing work by opening the gas ballast valve (this significantly reduces the pumping speed and ultimate pressure). The vacuum ducts must always be laid sloping downwards so that condensates can flow into the relevant separators.

In case of soiling by solid matter, the pump heads must be opened and the entire interior space, including valves and diaphragm, cleaned mechanically (see chapter 7.2.1).

5.4 Storage

The pumps are to be stored in a low-dust, interior room within the temperature range from + 5 to + 40 °C and at a relative air humidity < 90%.

Leave the protective elements on the intake and exhaust ports. Another equally good protection may be used.

5.5 Scrap Disposal

CAUTION !

The Laboratory-Vacuum-Systems must be disposed of in accordance with the 2012/19/EU guideline and the specific national regulations. Contaminated pump systems must be decon taminated according to the laws.

Operation

24 115041

6 Operation

6.1 LVS without vacuum controller

Switch the device (LVS 300 Z, LVS 301 Z, LVS 302 Z) on using the main switch. Vacuum is generated immediately and without regulation. Over the regulating valves on the LVS 302 Z it is possible two customers concomitant to connect.

6.2 LVS with vacuum controller

The LVS is switched on by the rocker switch POWER located on the device. The device is ready for operation after a short initializing routine, during which a signal tone sounds and all light elements light up briefly. In the version LVS with external controller (Order no. 115244-04) is the on / off power switch on the controller.

6.3 Operating modes of the Controller

The following modes are available:

0 -

STOP

Controller is inactive and can be configured

1 -

Manual operation

With specification of the setpoint and, if required, lowering

2 -

Automatic operation

The setpoint is detected automatically from the pressure development

3 -

Ultimate pressure

Pumping out at maximum motor output

4 -

Self cleaning

Motor runs for 2 minutes at open ventilation valve

6.3.1 Mode 1, Manual operation

The vacuum valve is closed when the pressure reaches the setpoint. Closed-loop control between the set hysteresis and the setpoint has been started. For operation with a frequency converter, an analog voltage is output, which controls the speed according to the standard tolerance. If the set pressure is not reached, the speed is automatically adjusted to the pressure loss. If the pressure is actively lowered, after the setpoint has been reached for the first time, it is lowered still further within a settable timeframe. The number of ramps can be set up to a maximum of 3. Each ramp starts with a holding time. The setpoint then falls in one step to the defined starting pressure. The setpoint then falls to the final value over the set time. After the last ramp, there is a waiting time until the automatic STOP (0 – the last set pressure is held indefinitely until STOP is pressed manually).

CAUTION !

When setting the ramps make sure that the set value is greater than or equal to the starting value of the first ramp.

The closed-loop control and hysteresis are always related to the current (reduced) setpoint. The changed setpoint always applies until the STOP button is pressed, then the configuration value applies once more. When the pressure reduction has finished, the control is stopped, and the system waits until the STOP button is pressed.

6.3.2 Mode 2, Automatic operation

After selection of the operating mode, the controller starts the evacuation. The pressure drop per minute is determined during this process. If increases during distillation by incipient boiling of the pressure, then this pressure value is taken as the setpoint and proceeds in the normal control operation.

Operation

115041 25

6.3.3 Mode 3, Ultimate pressure

By pressing of the key P min evacuation takes place at maximum pump speed until the user presses STOP.

6.3.4 Mode 4, Self cleaning

The Mode "Self cleaning" is used for flushing the pump and can, if desired, also be carried out several times in succession. After a waiting period of 5 seconds, the evacuation for 2 minutes (at maximum pump power and open vent valve) is carried out. A aborting the process at any time by pressing the encoder (4) possible. Self cleaning for Controller-version „cv“: The control valve (cv) remains closed when the mode Manual or Automatic the "ventilation at STOP" parameter = "0".

6.4 Monitoring by Level Sensor

If the level sensor input is activated (optional), the device goes into STOP status when "Tank full" is signalled.

6.5 Calibrating the Pressure Sensor

A two-point calibration is made with a comparison measurement device.

Calibration at ambient pressure:

Calibration at ultimate pressure:

- The diaphragm pump is switched off.

- The diaphragm pump is switched on.

- The venting valve is open.

- The venting valve will be closed.

- The vacuum valve is closed.

- The vacuum valve will be open.

- The ambient pressure to set.

- The ultimate pressure to set.

CAUTION !

Instead of measuring the pressure with a comparison measurement device, the ultimate pressure of the pump used may also be input if this is known with sufficient accuracy (take note of evacuation time). Ensure that the set pressure is also present at the sensor.

6.7.2 Software-Update

The software in the controller can be updated. It can be re-input by the user. The Fujitsu Flash tool must be used for the Fujitsu 16FX CPU range.

The factory default settings can be made with a corresponding sequential number input again (VCZ521_XXX.mhx).

NOTE !

The following screen appears after the start:

The graph shows the pressure development. Both the chronological and the pressure display range can be set. Data can also be recorded in the PC memory, which can then be stored as an ASCII file in the "File / Save memory" menu.

Operation

36 115041

In the PSI pressure range, the pressure values for the curve are multiplied by 100 to remain with integers.

The curve can be printed out by the system printer via the "File / Print curve" menu. The buttons largely correspond to the buttons on the controller. However, the buttons cannot

be held down.

In active mode, the AIR button can be used with the mouse like on the controller. Pressing the mouse button opens the valve, releasing it closes the valve again. However, this only works if the mouse pointer is still on the AIR button.

The Up and Down arrow buttons change the temporary setpoint in active mode. The OK button only works in active mode, and sets the current pressure as the new set

value. The Start button starts or ends in the current operating mode. The Pmin button functions the same as without a controller.

The following menu items can be selected from the menu bar:

6.8.3 Menu item: „Calibrate“

Calibration:

When search lower point (Pmin) is activated, evacuation is to the lower point. If the pressure does not fall any further, the value can be entered by using a comparison measurement device and confirmed with Ok. The system is vented and the ambient barometric pressure entered as the upper point (Pmax). Do not confirm until the value has been established.

If the controller is integrated in a complete system or pump system (LVS), evacuation and venting take place automatically when the stated buttons are pressed.

The calculated correction values are displayed and can be stored with save.

CAUTION !

Ensure that the set pressure is also present at the sensor.

Instructions for ATEX certification

Instructions for certification

- Laboratory-Vacuum-Systems LVS -

for use in Zone 2 in accordance with device

category 3 per ATEX Directive 2014/34/EU

« EX II 3G IIC T3X »

Internal atmospheres only

1. Type test – Effects of the ATEX Directive

Thanks to its design this device meets the requirements imposed upon devices of device group II and

device category 3 in conformity with Directive 2014/34/EU of the European Parliament and Council dated 26 February 2014 on the harmonisation of the legislation and administrative regulations of the member states with regard to devices and protection systems for use in atmospheres capable of being ignited. According to the regulations for category 3, these devices are intended to be connected to apparatus in which in normal operation a mixture of gases or vapours capable of being ignited does not normally occur or with a high probability does so only seldom and briefly.

The following instructions absolutely must be observed when using these devices.

• Because of the identical construction in principle of the devices of category 2 certified by IBExU (notified body), these studies relating to the internal space are used for illustration purposes.

This certification relates to the following device types: The certification is a type test per Directive 2014/34/EU. It relates to all the devices of the

m

anufacturer “Gardner Denver Thomas GmbH” with the designation “EX II 3G IIC T3X.”

In the specific case these are devices with the following type designations:

• LVS … - devices with a diaphragm diameter the diaphragm pump of 75 mm, 95 mm and 97 mm.

600 E; 1200 E; 1201 E; 2401 E;

101 Z; 110 Z; 300 Z; 301 Z; 302 Z; 310 Z; 311 Z; 320 Z; 901

201 T; 210 T; 600 T; 601 T; 602 T; 610 T; 611 T; 620 T; 1210 T

The certification relates to all versions including those that vary from the basic types. A precondition here is that the internal area in contact with the gas has not been changed.

Key:

• LVS - Designation

• EX - ATEX Directive 2014/34/EU

• 03 - Device category 3

• 01 - Serial number of the internal certification

WELCH_ATEX_03-01 1

Instructions for ATEX certification

The “EX II 3G IIC T3X” certification is valid only for the internal space in contact with the medium and the transport of gases and vapours. Installation and operation of the devices in an atmosphere capable of being ignited is not permitted.

The user should note that if accessories or components are added, the use of the above-mentioned devices in plant entails recertification to ATEX. In this event, the certification of the Gardner Denver Thomas GmbH devices lapses.

According to the definition in DIN “Device Category 3”, these devices are designed for use where in normal operation a mixture of gases or vapours capable of being ignited does not normally occur or with a high probability does so only seldom and briefly. The use of built-in gas ballast valves or other devices for the intake of air to check for leaks is only permitted if this does not generate any mixtures capable of being ignited in the internal space of the device.

Restrictions on the operating conditions as a result of designating the devices with an “X” (in accordance w

ith EN 13463-1 see Assessment of the risk of ignition).

• Devices are to be installed in such a manner that they cannot be damaged, heat is conducted away and visual monitoring is possible.

• The tolerances relating to ambient and gas intake temperatures in the operating instructions are to be observed.

• After maintenance or repair work has been carried out, the device concerned must be subjected to an appropriate inspection. The final vacuum stated in the documentation and a test on the seal of the internal space of the device are to be checked. The tested leak rate may not be under 0.5 x 10

-2

mbar x litres/sec.

2. Definition of explosive atmosphere

An atmosphere capable of being ignited is a mixture of air and combustible substances in the form of gases, vapours, mists or dust under atmospheric conditions in which, following ignition, the combustion process is transferred to the entire uncombusted mixture.

3. Area with a risk of explosion

By an area with a risk of explosion is meant an area in which the atmosphere may be capable of being i

gnited because of the local and operating conditions.

Note: The allocation of hazardous areas is a matter for the user.

4. Legal requirements for the manufacturer

Directive 2014/34/EU Legal requirements for the manufacturer are set out in:

• National implementation of the EX Decree

• DIN EN 1127-1

• DIN EN 50014-x

• DIN EN 13463-x

• IEC EN 60079-x

• IEC EN 61241-x

ertification is conducted by the in-house Production Inspection in accordance with the specifications set out in the documentation. Individual inspections are to be conducted. A complete record of the results for every device is to be stored in the PPS system.

Maintenance and repair

After repair or maintenance work has been carried out, the pump must be subjected to an inspection.

One inspection criterion is final pressure. If this is reached, it may be assumed that the leakage of the device lies within the required tolerance. This ensures that there is no mixture capable of being ignited within the internal space of the pump.

10. Technical documents for the EC type test

1. Risk assessment

2. Test certificate

3. Internal inspection and production inspection of the products

4. Declaration of conformity (CE)
