EC Declaration of Conformity We declare under our sole responsibility that this product corresponds to the regulations 2006/95/EC, 2004/108/EC, 1999/5/EC and 2011/65/EU and conforms with the standards or standardized documents: EN 61010-1, -2-010, -2-051; EN 61326-1 and DIN 12876-1. Explication of warning symbols DANGER indicates an imminently hazardous situation, which, if not avoided, will result in death, serious injury.
• A laboratory circulator refrigerates and circulates fluid according to specified parameters. This involves hazards due to low temperatures and general hazards due to the device of electrical energy. The user is largely protected by the device of relevant standards. Further hazard sources may arise due to the type of tempering fluid, e.g. by exceeding or undercutting certain temperature thresholds or by the breakage of the container and reaction with the refrigeration carrier fluid.
Unpacking • Unpacking: - Please unpack the device carefully - In the case of any damage a detailed report must be sent immediately (post, rail or forwarder). • Delivery scope: - RC 2 basic Refrigerated Circulators - Mains cables - Hose olive NW 12 (2 pieces) - Operating instructions - Warranty card. Preparations • Setting up: - Place the unit on an even, stable, clean, nonslip, dry and fireproof surface. - Keep at least 20 cm of open space on the front and rear side.
• Filling and draining: - Before filling the fluid into the bath, open the venting grid as indicated in following figure. Low Level High Level Red (High Level) Red (Low Level) Fig. 6 - Check and make sure that the drain valve is closed (the stop position in clockwise direction, see Fig. 7). Note: Please note information in section “Commissioning”. - Connect the mains plug and turn on the device with mains switch (2, see Fig. 1). - The low level warning message appear on the display.

• Moving the device: Empty all fluid in the bath before moving device from one place to other place. The device can be lifted up and moved by using the top handles or the bottom handles (12, see Fig. 1). It can also be moved on flat surface by lifting and pushing the front of the device. It is easy to move the device with the help of the wheels. The angle of inclination should never be more than 10 º at any direction when move the device! The device must not be moved during operation.
Commissioning NOTICE Before commissioning, make sure that the device has not been moved for one hour. Check whether the voltage specified on the type plate matches the mains voltage available. The power socket used must be earthed (protective earthing). If above conditions are met, the instrument is ready for operation after plugging in the mains plug. If these conditions are not met, safe operation is not guaranteed and the device could be damaged.
Menu settings • Menu structure: Default settings MODE A B C Activated 40 °C -20 °C 3200 rpm 1000 rpm 8 Maximum temperature (HI T) Minimum temperature (LO T) Maximum speed (HI R) Minimum speed (LO R) Fluid type (FLUI) Menu The type of temperature PID control arithmetic (AUTO) AUTO 1 AUTO 0 Proportional coefficient of PID (Kp 1) Integrate time of PID (Ti 1) Differential time of PID (Td 1) Activated 3.0 20.0 2.
• Temperature control type (AUTO): Proportional coefficient of PID (Kp 1) AUTO 1: AUTO 1 is the default setting. The default PID settings are used automatically. Cooling down curve in AUTO 1 control (AUTO 1): °C t The proportional coefficient Kp is the controller amplification and determines how strongly the control deviation (the difference between the target temperature and actual temperature) directly affects the control variable (cooling down time).
Example: 2-point calibration: Dip the temperature sensor of the reference measuring instrument into the bath fluid. Select 2-point calibration in the menu. Press the “OK/ Pump“ button (E) to start the 2-point calibration. Set the first point temperature (step 1, e.g. 10 °C) with “Pump (+)” button (F) or “Pump (-)” button (G). Confirm the setting by pressing “OK/Pump“ button (E).
Command syntax and format: The following applies to the command set: - Commands are generally sent from the computer (Master) to the device (Slave). - The device sends only at the computer’s request. Even fault indications cannot be sent spontaneously from the device to the computer (automation system). - Commands are transmitted in capital letters. - Commands and parameters including successive parameters are separated by at least one space (Code: hex 0x20). - Each individual command (incl.
USB cable A - Micro B 2.0: This cable is required to connect USB port (11) to a PC. A USB A USB micro B Fig. 15 Maintenance and cleaning To avoid contamination, it is essential to check and change the bath fluid from regularly. If water is used for bath fluid, we recommend to add Water bath protective media. The protective media stops the growth of algae, bacteria and other microorganisms with its bactericidal effectiveness. It protects the bath fluid and provides a long period of use for the fluid.
Error codes Any malfunctions during operation will be identified by an error message on the display.
Technical data Nominal voltage Frequency Max.
Warranty In accordance with IKA® warranty conditions, the warranty period is 24 months. For claims under the warranty please contact your local dealer. You may also send the machine direct to our factory, enclosing the delivery invoice and giving reasons for the claim. You will be liable for freight costs.
