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! 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
(SW 19) from the pump connector IN (9) and OUT (10).

- Via a hose to the “Overflow” connector, overflowing
fluid can be dir

ected into a suitable vessel. The ves­sel should be positioned lower than the “Overflow”
connector.
In case of closed external system, if there is in any case
no risk of exceeding the maximum fluid level, you can
close the “Overflow” connector with the included
overflow cap. This minimizes the energy loss and pro­tects, in case of long-term applications with low tem­peratures and high humidity, against unwanted water
input and the associated volume increase.
Check fluid heat expansion!

Connect the “Backflow” connector to IKA

calorim­eter with a suitable hose.
When IKA calorimeter is not connected, please close
the “Backflow” connector with included backflow cap.

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.

°C

t

Fig. 25 (cooling 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
(on-time 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.
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.

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 “Fluids (Standard
information for IKA fluid)“.
The maximum and minimum temperature values of the
selected fluid can be set within these limitations.

2. 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 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 heating up and cooling down process. This can pro­tects sensitive device like the glass reactors from thermal
shock (e.g. glass break).

3. Temperature sensor:

1) Calibration:

The internal and external temperature measurement can be calibrated and adjusted.
You can select 2-point calibration or 3-point calibration for internal and external measurement.

Interface and output

The device can be connected to a PC and operated with the
laboratory software labworldsoft

®

through the RS 232 port

(5), USB port (6) or USB port on the WiCo.

Note: Please observe the system requirements together
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 connected to a PC during operation (hot plugging).
Connected devices and their properties are automatically
recognized. Use the USB interface in conjunction with lab-

®

worldsoft

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. Con­figuration, command syntax and commands of the virtual
COM ports are as described in RS 232 port .

Device software update:
For device software update, visit IKA website www.ika.
com and enter the “Service” menu. Download and run

the Firmware Update Tool.
Find and click the Firmware Update Tool in your PC after
installation. Register your E-mail and password.
Connect the device to your PC via the USB cable. Then,
you can update the device software according to instruc­tions of the Firmware Update Tool.

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 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.

-

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 parame­ters 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 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 recom­mendations 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 co mmands 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.
