• A laboratory circulator heats/refrigerates and circulates flu-
id according 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
ensured 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

• Continuous monitoring of the bath and the filling level of
the bath fluid is required, especially at high temperatures�
• To ensure a sucient fluid circulation, the viscosity of the
bath fluid must not exceed of 50mm2/s at the lowest op-
erating temperature�
If water is used at higher tempera-
ture, there is heavy loss of fluid due
to the evaporation of the steam�
•
Untreated tap water is not recommended� It is recom-
mended to use distilled water or high purity water (ion ex-
changers) and add 0�1 g soda (sodium carbonate Na2CO3)
/liter, to reduce corrosive properties�
Risk of burning caused by vapor or
hot water at the outlet of the cool-
ing coil�
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 type,
must remove the remaining water
from the complete system (includ-
ing hoses and external devices)� When doing this, also
open the stopper and union nuts caps of the pump out-
puts and inputs and blow compressed air through all the
pump outputs and inputs! Beware of the risk of burning
due to delay in boiling!

tion, toxic or flammable vapors can arise� Ensure suitable
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 higher than
the adjusted safe temperature limit
that has been set� The safe temperature limit must always

Proportional coecient of PID (Kp 1):
Integral time of PID (Ti 1):
Differential time of PID (Td 1):
The proportional coecient 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�
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 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�
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�
•
External and internal temperature control (ET)
(heating):
ET 0: internal temperature control
ET 1: external temperature control
If the external temperature control (ET 1) is selected, the
following items EuT 2 (sampling time), Kp 2, Ti 2, Td 2,
Df t (maximum temperature difference between internal
and external temperature) and FAST could be set� Other-
wise they are not displayed in the menu list�
The sampling time EuT 2 (s) is the interval over which
the external control deviation and the respective control
variable (dependent on Kp 2,Ti 2, Td 2, Df t and FAST)
is determined�
EuT 2 must be adjusted to match the response charac-
teristic (total of all time constants) of the external closed
loop controlled system, so that the control variable can
deliver a uniform and measurable change in the control

interface (11) or the USB interface (12) connected to a PC and
with the laboratory software Labworldsoft®�
Note: Please comply with the system requirements togeth-
er with the operating instructions and help section included
with the software�
USB interface:
The Universal Serial Bus (USB) is a serial bus for connecting
the device to the PC� Equipped with USB devices can be con-
nected to a PC during operation (hot plugging)� Connected
devices and their properties are automatically recognized�
The USB interface can also be used to update firmware�
USB device drivers:
First download the latest driver from 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�
Configuration, command syntax and commands of the vir-
tual 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)�
- Each individual command (incl� parameters and data) and
each response are terminated with CR LF (Code: hex 0x0d
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�
The following table summarizes the (NAMUR) commands understood by the IKA®control equipment�
