Ensure that gases classified in explosion group IIC are not produced by materials or during chemical reactions, e.g. hydrogen.
Information on the device Note Meaning Name plate (example: MR Hei-Tec) Warranty seal Warning Before opening the box disconnect power plug. Warnung Vor dem Öffnen des Gehäuses Netzstecker ziehen. Note: please disconnect the connection to the power supply before opening the device.
Residual dangers Despite all precautions taken, residual risks can emerge which may not be immediately obvious! Adhering to the safety instructions, the intended use and the operating instructions as a whole can reduce residual risks! WARNING Risk of slipping! Risk of injury. After operation or in the event of malfunctions, there may be liquid on the floor close to the machine. Watch out for any wet spots and clean the floor if necessary. WARNING Errors! Risk of injury.
WARNING Unauthorized access is prohibited! Risk of injury. Risks arise if unauthorized persons enter the danger zone of the device. The operator is responsible for ensuring that unauthorized persons (e.g. visitors) do not have access to the danger zones (service area, protected areas). DANGER Failure to observe the danger zone, work area and service area! Dangers are posed by electrical and mechanical energies, as well as by residual dangers.
Device description The device is a magnetic stirrer and has the following functions: Stirring of substances. Heating of substances. Stir and/or heat the substances in a heat-resistant stirring container, with the underside on the hotplate. Set the stirring speed and heating temperature individually using the operating elements. Storage & transport CAUTION Damages as a result of improper transport! Damage can be caused to the device and the device mechanics in the case of improper transport.
Accessories (optional) Temperature sensor Pt 1000 (DIN EN 60751, Class A) NOTICE Immersion depth of temperature sensor Immerse the temperature sensor in the medium by at least 20 mm. Otherwise inaccurate measurements are possible. The temperature sensor Pt 1000 measures and regulates the temperature of the heated medium. 1. Switch off the device. 2. Connect temperature sensor. Heat-On block Securely position the heat-on block.
Heat-On 5 liter block (when using a support rod) Mount support rod with an extension arm. Start-up CAUTION The mains voltage and specification of the mains voltage on the name plate do not coincide! Damage to property as a result of overvoltage. Please ensure that the mains voltage coincides with the voltage specified on the name plate. CAUTION Unintentional switch-on of the device! Injury and burns to the hands. Switch off the device. Remove the mains plug after use.
DANGER Risk of electric shock or a short circuit! Risk of electric shock or short circuit due to melted insulation Ensure that all mains cables, pipes and connecting cables have been laid correctly in the area where heat is generated. 1. Switch off the device. 2. Insert device connection cable in the mains power plug. 3. Insert device connection cable in the power supply socket. 4. Switch on the device.
Operation Stirring MR Hei-Standard NOTICE Start stirring function The stirring function starts from a speed of 100 rpm. You can adjust the speed up to a speed of 1400 rpm. 1. Set set speed.
MR Hei-Tec 1. Set set speed. Example: 150 rpm Stirring function switched on? If you have already switched on the stirring function at this point in time, the appliance adjusts to the set value immediately. Acceptance of the set value The set value is accepted automatically after a few seconds or by pressing the rotating push button Hei Guide.
2. Switch on stirring function. Example: 150 rpm Heating NOTICE Set temperature setting value You can set the set temperature anywhere between 20 to 300 °C. 1. Switch off the device.
2. Select heating method a. or b. MR Hei-Standard a. Heating without temperature sensor b. Heating with temperature sensor The temperature is measured and regulated exclusively using the hotplate. NOTICE The actual temperature in the stirring container is always lower than the preset set temperature.
4. Set set temperature. Example: 50 °C 5. Switch on heating function.
MR Hei-Tec a. Heating without temperature sensor b. Heating with temperature sensor The temperature is measured and regulated exclusively using the hotplate. NOTICE The actual temperature in the stirring container is always lower than the preset set temperature. Factors to consider for temperature differences are the following: heat transfer resistance of the different stirring containers, heat transfer resistance of the quantity to be heated and heat loss due to radiation.
4. Set set temperature. Example: 60 °C Display element „ext“ If the temperature sensor is connected, the display element "ext" is also shown. Heating function switched on? If you have already switched on the heating function at this point in time, the appliance adjusts to the set value immediately. Acceptance of the set value The set value is accepted automatically after a few seconds or by pressing the rotating push button Hei Guide.
5. Switch on heating function. a. Heating without temperature sensor b. Heating with temperature sensor Example: 60 °C Fast-Mode and Precise-Mode You can choose between the following 2 modes as soon as you have switched on the heating function: The time saving Fast-Mode (factory setting) – allows for shortest heating-up times. The Precise-Mode - prevents an overtemperature situation categorically.
Display of set speed and set temperature (MR Hei-Tec) Readout the set speed and set temperature. Display element „ext“ If the temperature sensor is connected, the display element "ext" is also shown.
Calibrating (MR Hei-Tec) With the calibrating function, you can change the temperature of the medium measured using the temperature sensor Pt 1000 by a calibration value of -5 °C to +5 °C. Stirring function and heating function The stirring function and the heating function may not be active. 1. Connect temperature sensor (see chapter "Installation" – "Accessories (optional)" - „Temperature sensor Pt 1000"). 2. Calibrate temperature.
3. When you reach the desired setting, release the Hei Guide rotary-push button. Save settings The last selected settings remain saved following switching off and are offered to you first when setting again the calibrating function. Safety Plus (MR Hei-Tec) The Safety Plus function allows you to switch off error monitoring of the temperature sensor for errors "E21" and "E22" and back on again if required (default setting: "SAF On").
a. Switch off Safety Plus function b. Switch on Safety Plus function 3. Press Heating button again. 3. Press Heating button again. 4. When you reach the desired setting, release the Hei Guide rotary-push button.
