• The voltage stated on the type plate must correspond to
the mains voltage.
• The device can only be disconnected from the mains sup-
ply by pulling out the mains plug or the connector plug.
• Disconnect the mains plug before attaching or changing
any accessories.
• Disconnect the mains plug before cleaning, maintenance
and transportation of the unit.
• The device must only be opened by trained specialists,
even during repair. The device must be unplugged from
the power supply before opening. Live parts inside the
device may still be live for some time after unplugging
from the power supply.
Coverings or parts that can be
removed from the device with-
out the aid of any tools must
be put back on the device again to ensure safe opera-
tion, for example to keep foreign objects and liquids,
etc. from getting into the device.
• The device may only be used as prescribed and as de-
scribed in the operating instructions. This includes op-
eration by instructed specialist personnel.
• When using critical or hazardous materials in your pro-
cesses, IKA®recommends to use additional appropriate
measures to ensure safety in the experiment. For exam-
ple, users can implement measures that inhibit fire or
explosions or comprehensive monitoring equipment.
• Process pathogenic material only in closed vessels under
a suitable fume hood. Please contact IKA®application
support if you have any question.
If the power switch is not with-
in reach when device is operat-
ing, an EMERGENCY STOP
switch that can be easily accessed must be installed in
the work area.
• A laboratory circulator heats and circulates fluid accord-
ing to specified parameters. This involves hazards due to
high temperatures, fire and general hazards due to the
device of electrical energy.
The user safety can not be en-
sured simply with design requirements on the part of the
device.
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 heat carrier fluid.
It is not possible to consider all eventualities. They re-
main largely subject to the judgment and responsibility
of the operator. For this reason, it may become neces-
sary for user to take other precautionary safety mea-
sures.
• Insucient ventilation may result in the formation of explo-
sive mixtures. Only use the device in well ventilated areas.
The safety circuit (safe tem-
perature) must be adjusted so
that the maximum permissible
temperature cannot be exceeded even in the event of a
fault. Check the safe temperature circuit on a regular ba-
sis (see section “Setting the safety temperature“) .
• Securely fix the ICC immersion circulator for use at the
bath, so that it cannot tip over.
• When device is used for external circulation, extra pre-
caution must be taken for hot fluid leakage due to dam-
aged hose.
• Use suitable hoses for connection.
• Secure hoses and tubes against slippage and avoid kinks.
• Check hoses, tubes and bath at regular intervals for pos-
sible material fatigue (cracks/leaks).
• Mains cable should not get in contact with hot parts
and fluids.
• If you are using plastic bath, observe the permitted
working temperature range and fluids.
Do not start up the device if:
- It is damaged or leaking
-
Cable (not only supply cable) is damaged.
• Be careful when filling a hot bath.
At high operating tempera-
tures, the temperature of hous-
ing parts, surfaces and tubes
can exceed 70 ° C.

• Continuous monitoring of the bath and the filling level of
the bath fluid is required, especially at high temperatures.
• To ensure a sucient fluid circulation, the viscosity of
the bath fluid must not exceed of 50mm2/s at the lowest
operating temperature.
If water is used at higher tem-
perature, there is heavy loss of
fluid due to the evaporation.
• Untreated tap water is not recommended. It is recom-
mended to use distilled water or high purity water (ion
exchangers) and add 0.1 g soda (sodium carbonate
Na2CO3) /liter, to reduce corrosive properties.
Risk of burning caused by va-
por or hot water at the outlet
of the cooling coil (accessory).
Do not use the cooling coil with
water at bath temperatures >
95° C.
For bath temperatures > 60°C
make sure that the flow rate
through the cooling coil is high
enough.
Don't use following fluids:
- Untreated tap water
- Acids or bases
- Solutions with halides: chlorides, fluorides, bromides,
iodides or sulfur
- Bleach (Sodium Hypochlorite)
- Solution with chromates or chromium salts
- Glycerine
- Ferrous water.
When changing the bath fluid
from water to a heat transfer
fluid for temperatures above
100 °C, remove the remaining water from the complete
system (including hoses and external devices). When do-
ing this, also open the stopper and union nuts caps of
the pump outputs and inputs and blow compressed air
through all the pump outputs and inputs!
It is dangerous to touch the
heater. The temperature of the
heater can be very high.
• After a power failure during operation, the device may
start automatically (depending on operating mode).
• Transport the device with care.
• Do not transport or empty the bath while it is still hot.
This may result in accidents, especially scalding injuries.
In order to prevent the power
cable from falling into the fluid,
the mains cable must be se-
cured with the cable clamp (13, see Fig. 2).
Fluids:
Beware of the risk of burning
due to delay in boiling!
Only use fluids, which fulfill the
requirements for safety, health
and device compatibility. Be
aware of the chemical hazards that may be associated
with the bath fluid used. Observe all safety warnings for
the fluids.
• Depending on the bath fluid used and the type of opera-
tion, toxic or flammable vapors can arise. Ensure suit-
able extraction.
• Do not use any fluid which may cause dangerous reac-
tions during processing.
• Only use recommended bath fluid. Only use non-acid
and non corroding fluid.
Only process and heat up any
fluid that has a flash point high-
er than the adjusted safe tem-
perature limit that has been set. The safe temperature
limit must always be set to at least 25 ºC lower than the
flash point of the fluid used. Examine regularly the func-
tion of the safety temperature limiter.
Never operate the device with-
out sucient heat carrier fluid!
You should also be careful to
ensure that the minimum clearances and immersion
depths in the fluid are observed. Check the fluid level
detection at a regular basis (see section "Filling and
draining").

• Menu (Details):
TEMPERING:
Control:
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.
Control parameters:
Automatic: The optimal control parameters for PID tem-
perature 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.
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)" tem-
perature control:
Kp: Proportional coecient
The proportional coecient Kp is the controller amplifi-
cation and determines how strongly the control deviation
(the difference between the target temperature and ac-
tual temperature) directly affects the control variable (on-
time of the heater). 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 deter-
mines how strongly the duration of the control deviation
affects the control variable. Ti compensates for an ex-
isting 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 de-
termines 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.
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 val-
ues that are too small or too large can lead to instability
of the controller.
Fluids:
Under the option "Fluids", a variety of heat transfer fluids
can be selected.
The selected fluid limits the setting range of the target
temperature. See table in the section “Fluids“.
The maximum and minimum temperature values of the
selected fluid can be set within these limitations.
Limits:
Under the option "External (ext)", the maximum and
minimum temperature for external temperature control
can be set.
Under "l Δ T (int - ext) l", the maximum difference be-
tween the internal and external temperature can be set.
Under "Power Output", the maximum heating output
can be set as a percentage.
Temperature sensor
The internal and external temperature measurement can
be calibrated and compensated for.
By "calibration (Reset Calibration)", the calibration value
for the internal or the external temperature sensor will
be deleted.
Notification:
ON:

nected devices and their properties are automatically recog-
nized. Use the USB interface in conjunction with labworld-
soft®for operation in "Remote" mode and also to update
the firmware.
USB device drivers:
First, download the latest driver for IKA®devices with USB
interface from:
http://www.ika.com/ika/lws/download/usb-driver.zip.
Install the driver by running the setup file. Then connect the
IKA®device through the USB data cable to the PC.
The data communication is via a virtual COM port. Configu-
ration, command syntax and commands of the virtual COM
ports are as described in RS 232 interface.
RS 232 interface:
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 ac-
cordance with DIN 66 020 Part 1.
-
For the electrical characteristics of the interface and the al-
location of signal status, standard RS 232 applies in accor-
dance with DIN 66 259 Part 1.
- Transmission procedure: asynchronous character transmis-
sion in start-stop mode.
- Type of transmission: full duplex.
-
Character format: character representation in accordance
with data format in DIN 66 022 for start-stop mode. 1
start bit; 7 character bits; 1 parity bit (even); 1 stop bit.
- Transmission speed: 9600 bit/s.
- Data flow control: none
- Access procedure: data transfer from the stirrer machine to
the computer takes place only at the computer’s request.
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 param-
eters are separated by at least one space (Code: hex 0x20).
Sound:
The ”Sound” option allows the user to activate/deacti-
vate the key tone.
Factory Settings:
Select the ”Factory settings” option with "OK/Pump"
button. The system requests confirmation to restore the
factory settings. Pressing the ”OK” button resets all the
system settings to the original standard values set at dis-
patch from the factory (see "Menu structure").
Communication:
The ”Device name” menu option allows you to edit the de-
vice name.

- Each individual command (incl. parameters and data) and
each response are terminated with Blank CR Blank LF
(Code: hex 0x20 hex 0x0d hex 0x20 hex 0x0A) and have a
maximum length of 80 characters.
- The decimal separator in a number is a dot (Code: hex
0x2E).
The above details correspond as far as possible to the recommendations of the NAMUR working party (NAMUR recommenda-
tions for the design of electrical plug connections for analogue and digital signal transmission on individual items of laboratory
control equipment, rev. 1.1).
The NAMUR commands and the additional specific IKA
®
commands serve only as low level commands for communication
between the device and the PC. With a suitable terminal or communications programme these commands can be transmitted
directly to the circulator equipment. The IKA
®
software package, Labworldsoft
®
, provides a convenient tool for controlling
circulating equipment and collecting data under MS Windows, and includes graphical entry features, for pump motor speed
ramps for example.
