6 Safety Notes 4. Safety Notes These notes are intended to draw your attention to risks which only YOU can recognize and avoid or overcome. They are intended to enhance your own safety consciousness. We have set the highest quality standards for ourselves and this unit during development and production. Every unit meets relevant safety regulations. The correct unit usage and proper handling is however solely your responsibility. The intended workplace should correspond to a laboratory or pilot plant environment. The user should have an education level which is at least equivalent to a trained laboratory worker or specialized chemist. The following list should be seen as an example. The device may not be operated if there are any doubts regarding a safe operation due to the outer appearance (e.g. damages). A safe operation of the instrument cannot be guaranteed if the user does not comply with this instruction manual. Ensure that this manual is always at hand for every unit operator. Only use this unit solely for the intended application. Repairs, alterations or modifications must only be carried out by specialist personnel. Considerable damage can be caused by improper repairs. The Thermo Haake service department is at your disposal for repair work. Do not operate the unit with wet or oily hands. Do not clean the unit with solvents (fire risk) a wet cloth soaked in household detergent is normally sufficient. This device is not designed according to the standard EN : 1990 (DIN VDE and IEC 601-1) and should not be operated in rooms used for medical purposes and/or in the vicinity of patients. Only use heat transfer liquids recommended by Thermo Haake. Please refer to the respective EC Safety Data Sheet. 5

7 Safety Notes The temperature controlling i.e. immersing of test tubes, Erlenmeyer flasks or similar objects directly within the unit constitutes normal circulator practise. We do not know which substances are contained within these vessels. Many substances are dangerous: inflammable, easily ignited or explosive hazardous to health environmentally unsafe You alone are responsible for the handling of these substances Our advice: If in doubt, consult a safety specialist. Read the product manufacturer s or supplier s EC SAFETY DATA SHEET Read relevant regulations concerning dangerous materials Observe relevant guidelines for laboratories in your country The following measures were taken for the protection of the operator: Protection Class I according to VDE 0106 T1 i.e. protection against electric shocks by grounding all parts which carry the risk of electric contact. The device must only be connected to mains receptacles with a protective ground. Protection IP 20 according to EN i. e. regarding the protection against accidently touching live parts and damage by foreign matter, it has been ensured that foreign bodies with a thickness or diameter of more than 12 mm cannot penetrate. No special precautions were taken against the penetration of water and dust. The device should therefore not be used in a dusty atmosphere or in the neighborhood of spray water. Do not insert wires or tools in any of the openings. Complete separation from the mains is required when: all dangers caused by this device are to be avoided, cleaning is carried out, repairs or maintenance by specialist personnel is about to be carried out Complete separation means: Pull out the mains plug 6

8 Unit Description 5. Unit Description 5.1 Safety features The comprehensive safety system is designed on the principle of the concept of the single fault (EN 61010). This assumes that two separate faults do not occur simultaneously. This system therefore offers protection against one (single) fault. This one fault will effectively occur automatically if you... do not read this manual, do not correctly set the excess temperature protection, i.e. your safety reserves have already been used up. 5.2 Safety element The unit is equipped with an excess temperature protection. The unit can only be used with non-flammable liquids such as water or water with antifreeze. The safety element measures the surface temperature of the heating element. If this exceeds a certain temperature (due to e.g. a leakage in the liquid circuit or a liquid shortage), the safety element is triggered. If a safety feature is triggered fault display lights indicate the fault, the safety-relevant components of the heating unit (heating element ) are switched off immediately i.e. the safety circuit transfers the unit to a stable, safe condition, the water in unit gradually adjusts to ambient temperature. 5.3 Applications Temperature controlling and shaking of samples directly in the bath vessel.the samples have to be inserted into flasks or beakers. 7

9 Unpacking / Setting Up 6. Unpacking / Setting Up 6.1 Transportation damage? Notify carrier (forwarding merchant, railroad) etc. Compile a damage report. Before return delivery: Inform dealer or manufacturer (Small problems can often be dealt with on the spot). 6.2 Contents 1 Base unit with mains cable 1 Moveable platform with 4 rollers 1 Rubber connection piece 1 Instruction manual 1 Warranty card (please fill out and return) 6.3 Ambient conditions according to DIN EN indoors, max meters above sea level, ambient temperature C, relative humidity max. 80%/31 C ( 50%/40 C) excess voltage category II, contamination level 2 8

10 Information concerning the CE sign 6.4 Information concerning the CE sign Thermo Haake measuring and control instruments carry the CE sign which confirms that they are compatible with the EU guideline 89/336/EEC (electromagnetic compatibility). The tests are carried out according to module H (official sheet L380 of the European Community) as our quality assurance system is certified according to DIN / ISO It was tested according to the strict EMV test requirements of the EN /A1 (EMV requirements for electrical equipment for measuring technology, conduction technology and laboratory usage). This means it was tested for interference resistance and interference emission according to public low-voltage mains (household and commercial usage). The following basic standards were applied in detail: Interference resistance: EN electrostatic discharge EN electromagnetic fields EN fast transients EN surge voltages EN wire guided HF signals EN magnetic field of mains frequency EN voltage drop/short time interruption Interference emission: CISPR16/class B wire guided interference emission CISPR16/class B radiated interference emission EN Voltage variations and flickering EN Over-compensation voltage flows The application in industrial and commercial (public mains) environments is thus possible. A declaration of conformity is supplied with the ordered unit on request. Our strict standards regarding operating quality and the resulting considerable amount of time and money spent on development and testing reflect our commitment to guarantee the high level of quality of our products even under extreme electromagnetic conditions. Practice however also shows that even units which carry the CE sign such as monitors or analytical instruments can be affected if their manufacturers accept an interference (e.g. the flimmering of a monitor) as the minimum operating quality under electromagnetic compatibility conditions. For this reason we recommend you to observe a minimum distance of approx. 1 m from such units. 9

12 Assembly/Connecting Up 8. Assembly/Connecting Up 8.1 Connecting the platform to the guide rod Lift left end of the platform (11) until the rubber connection (10) at the bathbottom can be picked up and placed over the pin at the underside of the platform. 230 V 115 V 8.2 Connecting to a mains socket The unit should only be connected to a grounded mains sokket. Before the unit is actually connected to the mains, please compare the voltage indication on the name plate. Voltage tolerances up to +/ 10% are acceptable. 8.3 Changing the mains plug (e.g. for Great Britain) This should only be carried out by qualified specialist personnel The mains cable wires have the following colors: Brown = Live Blue = Neutral Green/Yellow= Earth 8.4 Fuses on the unit All units are equipped with automatic thermally-triggered fuses. If the fuse has triggered the fuse does not have to be exchanged resetting suffices; a white marking is visible; a certain cooling down time should be allowed (approx. 5 min) before the (dip) switch can be pressed again. Do not use tools; do not use force. Both destroy the fuse. If the fuse should be triggered again after resetting, the unit probably has a defect. In this case the unit should be sent in for servicing. 11

13 Setting up and Starting 9. Setting up and starting 9.1 Attaching clamps for vessels to the platform (11) Spring clips can be supplied to secure round vessels, e.g. Erlenmeyer flasks or beakers, to the platform. Maximum clamp number see chapter Filling in the bath liquid Liquid level: Can be selected anywhere between 50 and 180 mm (Thus, filling level dependent on objects used in the bath.) Only use water or water with antifreeze. 9.3 Ideal operating conditions for the shaking movement The following should be considered in order to warrant ideal operating conditions: a) Type and level of the bath liquid. b) Number, size, and weight of the test vessels. c) Amplitude of the shaking carriage movement. d) Number of carriage cycles per time unit (shaking frequency). The limiting conditions for the shaking movement: 1) Too large a shaking movement will cause high waves on the bath surface so that the liquid will splash over the top. 2) Large and heavy test vessels are attached to the platform and the amplitude and /or the frequency are too high. This means an overload for the shaking drive: An overload could lead to a standstill of the driving motor and eventually to its destruction if such operating conditions are kept up over a longer period of time. 12

14 Setting up and Starting The following rule will help to arrive at ideal operating conditions: At the beginning of the test, a small amplitude and a small frequency should be selected. Then the values of these two parameters may gradually be increased until the contents of the test vessels are sufficiently shaken and mixed. The shaking mechanism is also activated when the unit is switched on. Please observe the notes above regarding the shaking movement. It should especially be ensured that the shaking motor is not blocked due to the choice of unsuitable shaking motor parameters. If the SWB25 is only to be used as a waterbath, the rubber connection piece (10) of the platform (11) should be removed. 9.4 Operational safety The units are provided with an excess temperature safety circuit, the cut-off temperature of which has to be set at the dial button (5). In case of a temperature control malfunction which could overheat the bath, the heater of the water bath will be cut off. The malfunction indicator light (4) will then come on. 9.5 Draining The unit is drained at the nozzle Place a suitable vessel underneath nozzle. Bear in mind that the liquid will run out in a slight arc. 2 Turn plug slowly until it becomes disengaged from the thread. The liquid will start to run out. 3 Possible residues can be drained by tilting the circulator slightly. Hot heat transfer liquid should not be drained When certain conditions make draining necessary, please act safety conscious: Wear protective clothing and protective gloves 13

15 Operating Operating 10.1 Switching on Switch the unit on at the mains switch 1. The display 16 briefly shows the device identification Sb25, thereafter the version number of the operating software, e.g and then the actual shaking frequency. The shaking mode is started. The motor slowly reaches the set shaking frequency. Heating is started. If the shaking frequency is too high, then interrupt by pressing the Stop key Displaying the preset temperature Only possible in the temperture displaying mode (Display 17 C is lit). 1 Press menu key 7: Select preset temperature set temperature Small display C blinks. In display 16 the adjusted preset temperature is shown Adjusting the set temperature Only possible in the temperature displaying mode (Display 17 C is lit). 1 Press the menu button 7: Small display C blinks. 2 Press the temperature button 3: Displayed temperature value in the display. 3 Increase (+) or decrease ( ) the value shown in the display with the buttons 7. The first degree of temperature change is thereby passed slowly and thereafter the rate of temperature change in the display is five times faster. 14

16 Operating Press the enter button 8. The selected value is stored as new set temperature and activated. The new value is not saved until the Enter button has been pressed. The circulator continues to use the old set value. The display 16 automatically switches back to actual temperature display after a short time Heating control lamp The display 19 lights up when the heating is switched on (set temperature is higher than the actual temperature). display 19 lights up constantly during the heating up phase, display 19 flashes on and off during the control phase. The display 19 does not light up if the heating is not activated (set temperature is lower than the actual temperature). The heat transfer is carried out by convection from the heated bath bottom upwards. There are therefor small temperature gradients in the bath from the top to the bottom or from the bath side to the bath middle. This should be accounted for if a correction of the set temperature should be necessary Displaying the shaking frequency Only possible in the speed displaying mode (Display 17 n is lit). 1 Press menu key 7 : Select shaking frequency. Small display n blinks. In display 16 the adjusted shaking frequency is shown. 15

17 Operating 10.6 Adjusting the shaking frequency Only possible in the speed displaying mode (Display 17 n is lit). 1 Press the menu button 7: Small display n blinks Press the shaking frequency button 2: Displayed shaking frequency in the display. 3 Increase (+) or decrease ( ) the value shown in the display with the buttons 6. The first shaking frequency change is thereby passed slowly and thereafter the rate of shaking frequency change in the display is five times faster. 4 Press the enter button 8. The selected value is stored as new shaking frequency and activated. The motor slowly increases the shaking frequency. By pressing the enter button 8 once again, the actually reached frequency is stored as new set frequency. The new value is not saved until the Enter button has been pressed. The unit continues to use the old value. The display 16 automatically switches back to actual shaking frequency display after a short time. 16

18 Operating 11. Special functions 11.1 Adjusting the default values 1 Switch on the unit and press both keys 6 ( and + ). All adjusted parameters are set back on default values SOLL n RTA CT = 20.0 C = 20 rpm = 0.00 C In display 16 the message CodE appears Adjusting the RTA values (CT) (Temperature offset) Only possible in the temperature displaying mode. 1 Change from actual value display to preset value adjustment with key 7. Preset value (LED 17 blinks fast) 2 Change from SOLL to RTA with key 7 c (c0.00) appears on display 16. RTA value (LED 17 blinks every 2 seconds) 3 Change the value shown on the display with the keys 6 up + or down. The setting range for the temperature/rta value is ±10 C With negative values the display changes from c to. 4 Press input key 8 (Enter). The selected value is stored and activated as new value. Without pressing the Enter key the new value is not stored. The unit goes on operating with the old value. 17

19 Excess Temperature Protection 12. Excess Temperature Protection If a safety feature is triggered: The fault control lamp 4 lights up. all voltage conducting unit components (the heating element) are switched off immediately i.e. the safety circuit transfers the unit to a stable, safe condition. The fault cause must be identified and remedied. After the fault has been eliminated the unit can be started again by pressing the outer ring 5a. 5a Excess temperature protection dial It offers protection against dangers caused by an uncontrolled heating up of the heat transfer liquid above the desired set temperature. The cut-off temperature is adjusted with the excess temperature setting dial 5. Proper protection can only be guaranteed if the cut-off point has been correctly set Setting the excess temperature The cut-off point is set with the excess temperature dial 5 with a rough scale of temperature values arranged around it. This scale, of course, can only serve as an approximate setting means for this cut-off point. However, the cut-off point can be determined to act exactly if the following procedure is adhered to: If for instance a bath liquid has a fire point of 60 C the unit should cut off after reaching 35 C at the latest: 1 First set the desired set value using keys 6 (+), ( ) to exactly 35 C. 2 After the SWB25 has reached this temperature, turn the excess temperature dial 5 backwards very slowly (to the left) until the unit cuts off (acoustic signal, fault message). 3 Starting the unit after the heat transfer liquid has cooled down somewhat. 4 Then set the set temperature to the actual temperature (< 35 C). The unit can now be used for temperatures below 35 C. As soon as 35 C is reached, it is securely switched off. 18

20 Fault Display 13. Fault display 13.1 Sensor bath/short circuit At faults of the measured value recognition the message AL-F is shown. The display part AL blinks, the heater is switched off, the shaking process is not interfered as long as the fault is present. When the measured value recognition has regenerated itself the normal operation is continued Motor Motor is set on drive speed setting >0 rpm f there is no rotation at a drive speed setting of >0 the message AL-d is shown. The display part AL blinks, the heater is switched off as long as the defect is present. When the motor starts rotating the normal operation is continued Range sensor When any parameter (preset value, RTA) is out of its scope. Change values according to chapter 11. Should the defects appear regularly the unit has to be sent to the service. 19
