• A laboratory circulator refrigerates and circulates uid
according to specied parameters. This involves hazards
due to low temperatures and general hazards due to the
device of electrical energy. The user is largely protect-
ed by the device of relevant standards. Further hazard
sources may arise due to the type of tempering uid,
e.g. by exceeding or undercutting certain temperature
thresholds or by the breakage of the container and reac-
tion with the refrigeration carrier fluid. It is not possible
to consider all eventualities. They remain largely subject
to the judgment and responsibility of the operator. For
this reason, it may become necessary for user to take
other precautionary safety measures.
• Insucient ventilation may result in the formation of ex-
plosive mixtures. Only use the device in well ventilated
areas.
• 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).
• When device is used for external circulation, extra pre-
caution must be taken for cold fluid leakage due to
damaged hose.
Do not start up the device if:
- It is damaged or leaking
- Cable (not only supply cable) is damaged.
• 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 cold.
Check the temperature of the bath fluid before draining.
• Always empty the bath before moving the unit.
Always empty the bath if the unit
is unused for long time.
Fluids:
Only use the uids, which fulll 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 warning for the fluids.
• Depending on the bath uid used and the type of opera-
tion or toxic can arise. Ensure suitable extraction.
• Do not use any uid which may cause dangerous reac-
tions during processing.
• Only use recommended bath uid. Only use non-acid
and non corroding fluid.
Never operate the device without
sucient uid! Check the uid lev-
el detection at a regular basis (see
the section "Filling and draining").
• Continuous monitoring of the lling level of the bath uid
is required.
• For optimum temperature stability, the uids viscosity
should be 50 mm2/s or less at its lowest operating tem-
perature. This permits good fluid circulation and mini-
mizes heating from the pump.
• 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.
Don't use following uids:
- Untreated tap water
- Acids or bases
- Solutions with halides: chlorides, uorides, bromides,
iodides or sulfur
- Bleach (Sodium Hypochlorite)
- Solution with chromates or chromium salts
- Glycerine
- Ferrous water.

Fig. 12
The proportional coecient Kp is the controller ampli-
cation and determines how strongly the control devia-
tion (the difference between the target temperature and
actual temperature) directly affects the control variable
(cooling down time). Kp values that are too large can
lead to the controller overshooting.
The integral time Ti (s) is the correction time and deter-
mines how strongly the duration of the control devia-
tion affects the control variable. Ti compensates 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.
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 small can lead to instability of the controller.
AUTO 0: For special requirements, AUTO 0 can be used
with manual adjustment of the control parameters.
If the PID control (AUTO 0) option is selected, the fol-
lowing items including Kp 1, Ti 1 and Td 1 could be
set. Otherwise they are not displayed in the menu list.
Note: Inappropriate settings may produce the follow-

Interface and output
The device can be operated in “Remote” mode via the RS
232 interface (10, see Fig. 1) or the USB interface (11, see
Fig. 1) connected to a PC and with the laboratory soft-
ware Labworldsoft®.
Note: Please comply with the system requirements to-
gether with the operating instructions and help section
included with the software.
USB interface:
The Universal Serial Bus (USB) is a serial bus for connect-
ing the device to the PC. Equipped with USB devices can
be connected to a PC during operation (hot plugging).
Connected devices and their properties are automatically
recognized. The USB interface can also be used to update
rmware.
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 and install the driver by running the setup
le. Then connect the IKA®device through the USB data
cable to the PC.
The data communication is via a virtual COM port. Con-
guration, command syntax and commands of the virtual
COM ports are as described in RS 232 interface.
RS 232 interface:
Conguration
- The functions of the interface connections between the
stirrer machine and the automation system are chosen
from the signals specied in EIA standard RS 232 in ac-
cordance with DIN 66 020 Part 1.
- For the electrical characteristics of the interface and the
allocation of signal status, standard RS 232 applies in ac-
cordance with DIN 66 259 Part 1.
- Transmission procedure: asynchronous character trans-
mission 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 ow control: none
- Access procedure: data transfer from the stirrer machine to
the computer takes place only at the computer’s request.

14
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 parame-
ters are separated by at least one space (Code: hex 0x20).
- Each individual command (incl. parameters and data)
and each response are terminated with Blank CR 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 rec-
ommendations of the NAMUR working party (NAMUR rec-
ommendations 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 specic IKA®
commands serve only as low level commands for commu-
nication 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 conve-
nient tool for controlling circulating equipment and collect-
ing data under MS Windows, and includes graphical entry
features, for pump motor speed ramps for example.
