Basic Safety Instructions

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 o-pen when the pump is switched on. If there is more than one load on one LVS, they must be separated by check valves. 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 in-formation about the contamination (also negative information if necessary) and thorough cleaning of the laboratory vacuum system 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 LVS 110 Tp ecoflex 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.

113184 7

Basic Safety Instructions

2.3 Mechanical Systems Improper use can lead to injuries or material damage. Observe the following instructions: • Only operate the LVS with hoses of the specified dimensions. • The maximum permissible pressure of 1 bar at the suction connection must not be exceeded. • Solid particles in the pumping medium impair the pumping action and can lead to damage. Prevent

solid particles penetrating into the pump. • 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 envi-ronmentally compatible manner.

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 increase. Pre-

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

2.4 High Temperatures 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

2.5 Hazardous Substances

WARNING !

The operating company bears the responsibility for the use of the laboratory vacuum system.

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 regu-lations. Do not operate the laboratory vacuum system without a separator. 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 da-mage 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 The user must assess the process in accordance with Directive 1999/92/EC (ATEX 137) for the extraction of explosive gas/air mixtures inside or outside a similar environment. In accor-dance with the requirements indicated by this assessment, a suitable device must be se-lected which fulfils the specifications of Directive 94/9/EC (ATEX 95). Aggressive gases The diaphragm pump used is highly resistant to chemicals. In the case of particularly ag-gressive gases or products, the materials used for the pump parts in contact with gas must be assessed (as described in chapter 3.1.2). 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 ag-gressive 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 23. December 2004

• Regulations 2006/121/EC (classification, packaging and identification of hazardous substances), • Manufacturer's safety data sheets on hazardous substances.

Description

3 Description

3.1 Design and Function

3.1.1 Laboratory-Vacuum-System A rotary evaporator can achieve its full performance capability as a result of precisely controlled, ana-lytically pure vacuum. The Laboratory Vacuum System “LVS 110 Tp ecoflex” has been specifically designed to meet these requirements. The chemically resistant diaphragm pump “MPC 104 Tp” provides an oil-free, dry and thus analytically pure vacuum to an ultimate pressure of < 2 mbar. The maximum pumping speed of 1.1 m3/h is matched directly to the actual requirement by the speed control of the powerful and extremely quiet 24 V EC drive of the diaphragm pump. The LVS thus always works optimally. With a high quantity of gas under full power = maximum speed, with a low quantity of gas correspondingly slower. That protects the diaphragm pump, reduces the al-ready low energy consumption, and considerably reduces the noise level. At the same time, this de-sired reduction of the stroke rate leads to a reduction of the pump temperature and to increased con-densation. To prevent this, the pump heads are held at a constant temperature by a control system. Investigations have shown that this eliminates the need for a gas ballast valve. A gas ballast valve (see chapter 3.5) can be optionally mounted if this is not possible under certain conditions. The new design, the functional and well-arranged structure, and the smaller dimensions allow trouble-free, time-saving cleaning. A second operating console (operating pad) can easily be connected for remote control of the LVS 110 Tp ecoflex, for example for working in the extraction hood or in other critical areas. The LVS 110 Tp ecoflex is supplied complete with a suction-side separator and a pressure-side emis-sion condenser in the form of an intensive cooler.

Description 3.1.2 Diaphragm pump

Design: The diaphragm pump MPC 104 Tp con-sists of a pump body and a drive motor. The pump body consists of a drive shaft and four pump heads. Each pump head contains the diaphragm and the work valves. The two pump heads are arranged opposite each other. In a three-stage (T) diaphragm pump, the two pump heads are connected in parallel, two further pumps in series. The pump heads are driven via an eccentric shaft with a connecting rod.

Fig. 2 Diaphragm pump MPC 104 Tp

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 clo-sed (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 dia-phragm pump minimizes the pumping efficiency.

Assembly and Installation

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 Ilmvac GmbH 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 ILMVAC GmbH.

In case of a claim under warranty, the device must be returned in packaging that issuitable 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 suction connector of the LVS to your apparatus with vacuum hose DN8. • 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.

5.2.1 General instructions Observe the basic safety instructions when using the LVS. The pressure device regulation 97/23/EC must be observed if devices with an overpressure of 0.5 bar or more are connected. The pressures at the suction and pressure 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 ra-te. We recommend fitting non-return valves (order no. 720327) for applications with several consumers. The upstream separator on the suction-side serves to protect the diaphragm pump and the vacuum sensor from condensates and mechanical contamination. It must be used for an ap-plication. 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 suction-side can only be removed and emptied after the system has been vented.

16 113184

Assembly and Installation 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 nipples. 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 must always be clear, and the exhaust can be led off through a DN 8 hose into a suitable evacua-tion 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. 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).

5.3 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 suction and pressure ports. Another equally good pro-tection may be used.

5.4 Scrap Disposal

CAUTION !

The laboratory-vacuum-systems must be disposed of in accordance with the 2002/96/EC guideline and the specific national regulations.

Contaminated pump systems must be decontaminated according to the laws.

18 113184

Operation

6.2 Operating modes of the Controller Setting to different operating modes (see chapter 6.4.2)

Manual mode Mode 1

Lowering the working pressure until the set pressure has been attained and held constant. After switching on the power supply to the vacuum pump and controller, and selecting mode 1, the process is started by pressing the start button. The pressure is reduced to the set pressure value PS (mbar) 1), see Setting control parameters. In this way, the pressure is held constant by two defined threshold values (set value, hysteresis). This operating mode exemplifies the classical 2-point control. This control procedure is repeated until the operator terminates operation (STOP key). The receptacle may be ventilated by pressing the AIR key. The set value may also be changed during operation in manual mode by means of (↑,↓). This set value is not stored, so the set value present at program start is retained. (see chapter 6.2.5) "ecoflex" pump models work directly at the set pressure value.

Manual mode with settable pressure reduction Mode 2

As in operating mode 1, but with an additional function for adapting the evacuation process to processes in which the boiling point shifts (reduction of the concentration of the volatile com-ponent). After attaining the set pressure value PS, there is a further pressure reduction corresponding to the set pressure value PL (1...1000 mbar) and a time tL (1...240 min) 2) which has to be defined previ-ously. The maximum rate of change of pressure is limited to 1 mbar/s.

Mode 5 Automatic operation

Lowering the working pressure until a boiling point is found automatically (also with mixtures).In the automatic operating modes, the controller continuously checks the course of the pumping out curve (pressure change per unit time). It interprets significant deviations in the slope as the start of vapour formation and defines this pressure point as a set value. That is, the controller treats the value found in this way from now on in the same way as the set value in the previous modes. The sensitivity of the controller can be set with parameter PA (a higher PA value for volatile substances and a lower PA value for non-volatile substances, (see Setting control parameters)). After finding the pressure point, the controller carries on working in mode 1. In the case of certain solvent mixtures or deeply cooled condensates, the optimal boiling point is not always found. In such cases, the distillation process may be further optimised by repeating with chan-ged PA values. Maximum distillation speed can be achieved in this way, taking into account the cooler capacity and the stability of the vaporization process (no frothing of the distillate).

Automatic operation with settable pressure reduction Mode 6

As operating mode 5, and after the boiling point has been found, in order to get a further low-ering of the working pressure corresponding to the set pressure value PL (mbar) and tL (min) 2) .

CAUTION !

The vacuum controller is released for the application of modes 1, 2, 5 and 6. The mode required is selected according to the work task and the connected periph-eral equipment.

Operation 6.2.1 Selection, display of operating modes

After switching on, the desired operating mode can be set with the cursor keys ↑ UP and ↓ DOWN. The current operating mode appears in the first position of the display and is acti-vated with the START key (a "-" appears in the second position of the display). The STOP key terminates the operating mode ("-" disappears) and the control is thus disabled. The current control parameters can be brought into the display while the program is running without interrupting the control sequence by pressing the START key for 3 seconds. The code letter of the currently selected parameter appears in the STATE display field and its associated value in the VALUE display field.

6.2.2 Setting / changing the control parameters at the controller The configuration menu is used to set the control parameters. It may only be entered when the control is inactive (control interrupted with the STOP key). Press the OK button for three seconds. The mode code in the VALUE display field changes to P. Select the setting parameter with the ↑ UP and ↓ DOWN buttons (see table below). Only those parameters which have to be set for the selected mode are displayed. Key to the code letters: P Pressure settings in (<de> = set pressure unit mbar, torr or psi) PS <de> Set value Modes 1, 2 PL <de> Amount of pressure reduction (Low pressure) Modes 2, 6 PA <de>/min threshold value for detecting the boiling point automatic mode Modes 5, 6 t Time setting tL min Time for the pressure reduction (Low pressure) Modes 2, 6 tH min After-running time for the cooling water (H2O) Modes 1, 2, 5, 6 C Pressure sensor calibration CH <de> at normal pressure 3) (High) CL <de> at low pressure (Low) (at lowest possible pressure, e.g. 10 mbar) F Frequency reduction in %, starting from the maximum operating frequency FA % For determining the boiling point smoothly.

After selecting the parameter, confirm it with OK. This display changes to "E". Set the desired value with the↑ UP and↓ DOWN keys, confirm with OK, and repeat with the other required parameters if necessary. Press the STOP key to leave the setting menu. The set values are stored after the setting menu has been left.

20 113184

Operation 6.2.3 Setting the selected control parameters

During operation, the current pressure value (mbar) is shown in the VALUE display field, there is a "P" in the STATE display field.

6.2.4 Querying the set values The set values can be displayed during operation by repeatedly pressing the START button.

6.2.5 Changing the pressure during operation The set value can be changed at any time by pressing the UP and DOWN keys. The display changes from "P" to "S" during the setting. This set value is temporarily active. After pressing the "STOP" button, the originally stored set value becomes active once more. If this iteratively determined set value is to be permanently transferred into the memory, this may be done by pressing the OK key once. The diaphragm pump is switched to continuous operation by pressing the Pmin button, irre-spective of the set parameters.

6.2.6 Set minimum pressure The diaphragm pump is switched to continuous operation by pressing the Pmin button, irre-spective of the set parameters. The attainable minimum pressure stabilizes after an ade-quate waiting time.

6.2.7 Venting the system The system may be vented by pressing the AIR key at any time. However, it must be noted that this also ends the search run in automatic mode. Venting is intermittent while the controller is active. That is venting takes place only as long as AIR is kept pressed. When the controller is inactive, pressing AIR completely vents the system. Whether or not automatic venting takes place after finishing operation can also be set with the "ILMVAC-Control" program. (Dialog box element: „air valve at STOP“) OFF means the automatic venting switched OFF. ON means the automatic venting switched ON.

CAUTION !

If check valves have been fitted in the vacuum system, its venting may be restricted from time to time!

113184 21

Operation 6.2.8 Setting the after-running time for the cooling water

The cooling water valve (optional) can be used to cut-off a cooling circuit after a time delay after pressing STOP. The after-running time tH can be set for all manual and all automatic modes (1, 2, 5, 6). The value tH = 0 is a special case. In this case, the cooling water valve remains open, even after STOP.

6.3 Calibration The calibration menu enables long-term changes in the pressure sensor to be compensated for. Calibration should take place every six months or whenever displayed pressures cease to be plausible. We recommend that the calibration be performed with a comparison measurement device. For this, the measured values: normal 3) and low pressure must be input. Calibration can be made on the control panel or somewhat more easily with the "ILMVAC-Control" PC program (see chapter 6.4).

6.3.1 Run via control panel # Switch the device on at the HS ("Hauptschalter" - main switch, rear side of device) # Press the OK key for 3 seconds # Select the calibration parameter CL (↑, ↓) # Press the OK key – “E” appears in display # Evacuate until ultimate pressure < 50 mbar # Set the pressure from the comparison measurement device with the cursor keys ↑ UP

and ↓ DOWN # Confirm correspondence with OK, this is followed by automatic venting to atmospheric

pressure. # Press the ↑ UP key – CH appears in the display (Calibrate, High) # Press the OK key – "E" appears in display # Set the daily air pressure with the cursor keys ↑ UP and ↓ DOWN # Press the OK key – "E" disappears # Press the STOP key to leave the setting level, setting is stored

CAUTION !

Instead of measuring the pressure with a comparison measurement device, the ulti-mate 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.

Operation

6.4 Operation using the "ILMVAC-Control" The "ILMVAC-Control" PC program enables the vacuum controller to be operated simply and easily from the PC. The program is optionally available, together with the matching data cable, under order number 620617. Connection options of the dual data cable VCZ 424

The dual-data cable must be properly connected to COM 1 or COM 2 of your PC so that the "ILMVAC-Control" program automatically recognizes the vacuum controller. The cable end marked P must be inserted into the RS 232 socket on the controller. The end marked S must be inserted into the COM port of your PC. First connect the cable, then switch on the controller. It should start perfectly normally, and indicate the current pressure. After "ILMVAC-Control" has been started, the Measure dialog is displayed with the pressure curve diagram. Instructions for the RS 232 connection and program start If the cable is connected the wrong way round, the controller starts in software update mode instead of in regular operating mode. In software update mode, the display goes out after an initial beep. The controller software can now be updated via the dual data cable. Mnemonic aid for connecting the cable: P end for programming mode on the PC. Internal wiring of the controller RS232 port

113184 23

Operation The vacuum controller can also be connected to COM 3 or higher. However, "ILMVAC-Control" can then no longer automatically recognize the device. The number of the COM port then has to be transferred as a parameter when the program starts. If your controller is connected to COM 3, you must input the following command in order to start "ILMVAC-Control".

The command can be input, for example in the Windows start menu via "Run". The quotation marks in the command are only required if there is a space in the file path. The following screen appears after the start:

The graph shows the pressure development after pressing the START button.

24 113184

Operation The time axis (time range) and pressure axis (pressure 0..n) can be scaled, and the sam-pling rate (saving interval) can be set with the dialog box elements below the diagram. Only those buttons relevant to the currently set mode are active. Break (F7) and Reset (F9) are not needed for the vacuum controller modes. • The buttons can be operated with the mouse, as on the controller (see chapter 6.1). • The UP and DOWN arrow buttons change the temporary set value in active MODE.

• The OK button sets the current pressure as the new set value in active MODE. • The START button starts the selected operating mode. • The STOP button ends an active operating mode.

Enables the selection of the control algorithm for controllers with a control valve. In the case of the cv, the valve is simply closed when the setpoint is reached. In the case of the ccv, the control valve is briefly opened and closed several times shortly before the setpoint is reached. ccv prevents the setpoint being passed under certain circumstances. However, both algorithms usually work well. 1 - manual (Manual pressure setting for boiling pressure see Solvent table, chapter 6.5) 2 - manual, pressure drop (Manual pressure setting with additional pressure drop) 5 - automatic (automatic finding of the boiling pressure) 6 - automatic, pressure drop (automatic finding of the boiling pressure with additional pressure drop)

Operation 6.4.3 Menu item: „Alarm“

Timer function The time switch function is set via the PC level alarm. Two switching points are provided, each with a START and a STOP time. The START switching point behaves like an actuation of the START key, the STOP switch-ing point corresponds to the STOP key. All times are entered in hours and minutes. It is always used as the last module to be star-ted. The desired days of the week can be selected for each switching point. The switching point is deactivated is no day of the week has been selected. If the STOP time is earlier than the START time, then the system will not be stopped until the following day. Each time a switch-ing point is changed; the next START point is selected and activated together with its STOP point. This occurs both when the device is switched on and when the STOP point is reached.

28 113184

Operation 6.4.4 Menu item: „Calibrate“

Calibration When SEARCH (lower point) 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 de-vice and confirmed with OK. The system is vented and the ambient barometric pressure en-tered as the upper point. 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.
