Safety
Time Out:
In the “Time Out“ menu, the user can set a time limit. This time
limit applies if there is a communication failure between the EU-
ROSTAR station and the Wireless Controller or the communica-
tion range is exceeded. The EUROSTAR station will continue to
run at the set speed until the set time has expired. After that the
EUROSTAR stirrer (station) will continue to run at the set safe
speed (see the "Safe speed" menu).
Note: The initial setting for the time limit is 30 seconds. The user can
set a value of up to 60 minutes for this time limit.
If the intermittent mode is activated, the EURO-
STAR station immediately switches to run at
the set safe speed, or the set speed if that is less than the safe speed.
Safe Speed:
In the “Safe Speed“ menu, the user can specify a speed that is ap-
propriate and safe for the stirring task. The safe speed applies if there
is a communication failure between the EUROSTAR station and the
Wireless Controller or the communication range is exceeded.
Note: The initial setting of the safe speed is 150 rpm, and is imple-
mented after expiry of the time limit (see "Time out").
Password:
In the “Password“ menu, the user can protect the Wireless Controller
settings using a password (factory setting: 000).
CAUTION
Settings
Languages:
The “Languages“ option allows the user to select the desired lan-
guage by turning and pressing the rotary/push knob (B). A tick indi-
cates the language that is set for the system.
Units:
The ”Units“ option allows the user to select the desired unit for
displaying the temperature. The choice is between ”°C” or ”°F” and
is made by turning and pressing the rotary/push knob (B). A tick
indicates the unit that is set for the system.
Display:
The ”Display“ option allows the user to change the background
color and brightness of the working screen.
Sound:
The ”Sound” option allows the user to activate/deactivate the key-
press sound and to set the volume.
Factory Settings:
Select the ”Factory Settings” option by turning and pressing the
rotary/push knob. The system requests confirmation to recreate the
factory settings. Pressing the ”OK” button resets all the system set-
tings to the original standard values set at dispatch from the factory
(see "Menu structure").
Bluetooth
® :
The ”Bluetooth ® ” option allows the user to activate/deactivate the
”Bluetooth ® ” function. A tick shows that the option is activated.
Information:
The ”Information” option offers the user an overview of the most
important system settings of the stirrer EUROSTAR 20 high speed
control.
Interfaces and outputs
The device can be operated in “Remote” mode via an RS 232 or USB
interface using the laboratory software labworldsoft
® .
The RS 232 interface at the back of the device is fitted with a 9-pole
SUB-D port which can be connected to a PC. The pins are assigned
serial signals.
The USB port at the rear of the stirrer is used for the connection
between the PC and the Wireless Controller (WiCo). The Wireless
Controller also has a USB port, located on its right side. It can also be
used to connect to a PC for “remote control“.
Note: Please comply with 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 dur-
ing operation (hot plugging). Connected devices and their properties
are automatically recognized. Use the USB interface in conjunction
with labworldsoft
® for operation in "Remote" mode and also to up-
date the firmware.
USB device driver
First, download the latest driver for IKA
® devices with USB inter-
face from http://www.ika.com/ika/lws/download/usb-driver.zip and
install the driver by running the setup file. Then connect the IKA
® de-
vice through the USB data cable to the PC. The data communication
is via a virtual COM port. Configuration, command syntax and com-
mands of the virtual COM ports are as described in RS 232 interface.
Serial interface RS 232 (V24)
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 com-
puter 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
stirrer machine (Slave).
- The stirrer machine sends only at the computer’s request. Even fault
indications cannot be sent spontaneously from the stirrer machine
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).
