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�

- The place for installation should be large enough and provide sucient air ventilation to ensure the room does not warm up excessively because of the heat from device radiates to the environment�

- Do not set up the device in the immediate vicinity of heat sources and do not expose to sun light�

- Cooling machine, pump motor and electronics produce intrinsic heat that is dissipated via the venting grids (3)! Never cover these venting grids!

Note: After setting up the device, wait at least one hour before starting the operation to avoid the damage to the cooling system�

• Connecting the tubings:

- Unscrew the union nuts and stoppers using a wrench (SW19) from the pump connector IN (14) and OUT

Stopper

(13)�



- Connect the hoses for circulating the external system to the pump connection M 16 x 1 for IN and OUT directly or with the olives�

- Screw the hose olives to the pump connection IN and OUT with union nuts� Slide the hoses (NW 12) onto the olives� The hoses must be secured with suitable clamps�



Fig. 5

- Via a hose to the “Overﬂow” connector, overﬂowing ﬂuid can be directed into a suitable vessel� The vessel should be positioned lower than the “Overﬂow” connector�

TEMPERING:

1. Control:

1) Control Mode:

Internal (int): The temperature is regulated according to the internal temperature sensor�

Extern (ext): The temperature is regulated according to the external temperature sensor�

2) Control parameters:

Automatic: The optimal control parameters for PID temperature control are determined automatically� This is the recommended mode� Selecting "Automatic" allows you to set the dynamics for temperature control�

Accurate: precise tempering without overshooting� Fast: fast tempering with minimal overshooting�

Ts: Sampling time

The sampling time Ts (s) is the time interval over which the control deviation is determined and the respective control variable (dependent on Kp, Ti and Td) is calculated� Ts must be adjusted to match the response characteristic (total of all time constants) of the closed loop controlled system, so that the control variable can deliver a uniform and measurable change in the control deviation� Ts values that are too small or too large can lead to instability of the controller�

Prop_Bp: Proportional Band Maximum� Prop_Bn: Proportional Band Minimum�

The Proportional Band is the range below (Prop_Bp) and above (Prop_Bn) the set value in which the control output value is calculated via the difference between the actual and the set value and the PID parameters�

Examples of non-optimal settings:

Kp too high

Fig. 27

(heating curve in "Automatic" mode) Manual: The control parameters for PID temperature control can be set manually� "Manual" should only be used in the event of special temperature control requirements� When "Manual" is selected, the following parameters can be set for "Internal (int)" and "External (ext)" temperature control: Kp: Proportional coecient The proportional coecient 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 (ontime of the cooling)� Kp-values that are too large can lead to the controller overshooting� Ti: Integral time The integral time Ti (s) is the correction time and determines how strongly the duration of the control deviation affects the control variable� Ti compensates for an existing control deviation� A high Ti means a smaller and slower effect on the control variable� Ti-values that are too small can lead to instability of the controller� Td: Differential time The differential time Td (s) is the derivative time and determines how strongly the rate of change of the control deviation affects the control variable� Td compensates for rapid control deviations� A high Td means a smaller and slower effect on the control variable� Td-values that are too large can lead to instability of the controller�

Ti too low

Kp too low Ti too high

Td too high

3) Fluids:

Under the option "Fluids", a variety of ﬂuids can be selected� The selected ﬂuid limits the setting range of the target temperature� See table in the section “Fluid (Standard information for IKA® ﬂuid)“� The maximum and minimum temperature values of the selected ﬂuid can be set within these limitations�

4) Cooling:

This menu option allows you to activate/deactivate the cooling function�

Under "l Δ T (int - ext) l", the maximum difference between the internal and external temperature can be set� The function limits the absolute temperature difference between the external system and internal bath during the

Under the option "External (ext)", the maximum and minimum temperature for external temperature control can be limited�

heating up and cooling down process� This can protects sensitive device like the glass reactors from thermal shock (e�g� glass break)� Under “Power Output“, the maximum heating output can be set as a percentage of nominal heat output�

3. Temperature sensor:

The internal and the external temperature measurement can be calibrated and adjusted� You can select 2-point calibration or 3-point calibration for internal and external measurement� Calibration proceeding (example: 2-point calibration):

Conﬁguration

- The functions of the interface connections between the stirrer machine and the automation system are chosen from the signals speciﬁed in EIA standard RS 232 in accordance with DIN 66 020 Part 1�

- For the electrical characteristics of the interface and the allocation of signal status, standard RS 232 applies in accordance with DIN 66 259 Part 1�

- Transmission procedure: asynchronous character transmission in start-stop mode�

- Type of transmission: full duplex�

Maintenance and cleaning

To avoid contamination, it is essential to check and change the bath ﬂuid 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�

To keep the full cooling performance, the dust ﬁlter of the cooler must be checked regularly and cleaned if necessary�

• Switch off the device and disconnect power cable�

• Open the front venting grid (3)�

• Remove the bracket�

• Clean condenser dust ﬁlter with a vacuum cleaner or

wash the ﬁlter in the water and dry it before assembly�

Note: Don’t touch the condenser surface with hard parts�

Cleaning:

Disconnect main plug prior to cleaning!

Use only cleaning agents which have been approved by

®

to clean the device�

When ordering spare parts, please give:

- machine type

- serial number, see type plate

- item and designation of the spare part, see www.ika.com

- software version�

Repair: Please send in device for repair only after it has been cleaned and is free from any materials which may constitute a health hazard.

For repair, please request the “Decontamination Certiﬁcate” from IKA®, or download printout of it from the IKA® website www.ika.com� If you require servicing, return the device in its original packaging� Storage packaging is not sucient� Please also use suitable transport packaging�

For materials which are not listed, please request information from IKA® application support� Wear protective gloves while cleaning the devices� Electrical devices may not be placed in the cleansing agent for the purpose of cleaning� Do not allow moisture to get into the devicewhen cleaning� Before using another than the recommended method for cleaning or decontamination, the user must ascertain with

IKA® that this method does not damage the device�

 Note: When the heating function is not activated, the screen show only these warning information if ﬂuid level is too high or too low�

When the heating function is activated, if the ﬂuid level goes slowly up/down to the warning level, the screen show high/ low ﬂuid level warning message and icon� If the ﬂuid level is corrected, the warning message and high/low level icon disappear� After low ﬂuid level warning, if the ﬂuid level decreases further, the screen show Error 6�

If the actions described fails to resolve the fault or another error code is displayed then take one of the following steps:

- Contact the service department

- Send the device for repair, including a short description of the fault�
