DANGER
if you have any questions.
Process pathogenic materials only
in closed vessels under a suitable
fume hood. Please contact IKA
Beware of hazards due to:
WARNING
- flammable materials
- incorrect container size
- overfilling of media
- unsafe condition of container.
®
NOTICE
• The working plate can heat up due to the action of the
drive magnets at high motor speeds.
• The centre of gravity of the assembly must lie within the
surface on which it is set up.
• It may be possible for wear debris from rotating accessory
parts to reach the material being processed.
• When using PTFE-coated magnetic bars, the following
has to be noted: Chemical reactions of PTFE occur in contact with molten or solute alkali metals and alkaline earth
metals, as well as with fine powders of metals in groups 2
and 3 of the periodic system at temperatures above 300
°C - 400 °C. Only elementary fluorine, chlorotrifluoride
and alkali metals attack it; halogenated hydrocarbons
have a reversible swelling effect.

- splashing and evaporation of liquids
- ejection of parts
- release of toxic or combustible gases.
Effects of the magnetic field
have to be taken into account
(e.g. data storage media, cardiac
pacemakers ...).
Wear your personal protective
equipment in accordance with
the hazard category of the media
For protection of the device and accessories:
• Set up the device in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.
• The voltage stated on the type plate must correspond to
the mains voltage.
• Removable parts must be refitted to the device to prevent
the infiltration of foreign objects, liquids etc..
• Protect the device and accessories from bump and impact.
• Do not cover the device, even partially e.g. with metallic
plates or film. This may result in overheating.
Performing trials:
Reduce the speed if:
NOTICE
- the medium splashes out of the vessel
- the device is not running smoothly
- dynamic forces start to cause the device and/or the ves-
sels placed on it to move around.
• Make certain that the device is set at the lowest speed
(left hand position) before commissioning; otherwise, the
device will start to run at the speed set in last operation.
Gradually increase the speed.
• After an interruption in the power supply or a mechanical interruption during working process, the device will
restart automatically.
DANGER

a magnetic stirrer without heating function. The devices are
suitable for stirring and mixing liquid substances up to 50
liter (MIDI MR1 digital) and 150 liters (MAXI MR1 digi-
tal). The built-in stirring drive permits the stirring of substances with the aid of a magnetic stirring bar in the vessel.
The mixing intensity is dependent on the motor speed and
the size of the magnetic bar.
• Use:
- for stirring and mixing liquids.
Intend use: Tabletop device
• Range of use (indoor use only):
- Laboratories - Schools
- Pharmacies - Universities
Unpacking
• Unpacking:
- Please unpack the device carefully.
- In the case of any damage a detailed report must be
sent immediately (post, rail or forwarder).
This device is suitable for use in all areas except:
- Residential areas.
- Areas that are connected directly to a low-voltage supply
network that also supplies residential areas.
The safety of the user cannot be guaranteed:
- If the device is operated with accessories that are not supplied or recommended by IKA
®
.
- If the device is operated improperly or in contrary to the
®
IKA
specifications.
- If the device or the printed circuit board are modified by
third parties.
• Delivery scope:
®
- IKA
MIDI MR 1 digital or MAXI MR 1 digital ac-
cording to order
- Magnetic stirring bar
- Mains cable
- USB 2.0 cable A – B
- Operating instructions
- Warranty Card.
Commissioning
Check whether the voltage specified on the type plate
matches the mains voltage available.
The power socket used must be
earthed (protective earthing).
If above conditions are met, the device is ready for operation after plugging in the mains plug.
If these conditions are not met, safe operation is not guaranteed and the device could be damaged.
Observe the ambient conditions (temperature, humidity,
etc.) listed under “Technical Data”.
The device can be operated in two modes, “Continuous
mode“ or “Timer mode“:
Fig. 3
BC
Continuous mode:
) To switch the device on, turn the “On/Off” and “Timer”
rotary knob (B, see Fig. 3) clockwise to the “1” position.
Ö The device is now running in “Continuous mode”.
) To switch the device off, turn the “On/Off” and “Timer”
rotary knob (B) to “0” position.
Timer mode:
) To switch the device on, turn the “On/Off” and “Timer”
rotary knob (B) clockwise after the “
“ position.
Ö The running time can be adjusted to any value between
0 and 55 minutes.
Ö After the selected time period has elapsed, the switch
will automatically return to the “0”position and the de-
vice will remain switched off.
Ö The time period selected can be adjusted at any time.
Setting the motor speed:
) Set the motor speed by turning the “Speed” rotary knob
(C, see Fig. 3). The motor speed can be set to between
0 to 1000 rpm for MIDI MR 1 digital and 0 to 600 for
MAXI MR1 digital.

Interface and output
The device can be connected to a PC and operated with
the laboratory software labworldsoft
®
through the RS 232
interface (G, see Fig. 2) or USB interface (H, see Fig. 2).
Note: Please observe the system requirements as well as
the operating instruction and help section of 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 labworldsoft
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 interface.
RS 232 interface:
Configuration:
- The functions of the interface connections between the
device 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 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 device 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
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 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
®
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 device. The IKA
ware package, Labworldsoft
®
, provides a convenient tool
®
soft-
for controlling the device and collecting data under MS
Windows, and includes graphical entry features, for motor
speed ramps for example.

set point speed. The PC 2 warning is displayed. The WD2 event can be reset with OUT_WD2@0resetting also blocks the watchdog function. Set the watchdog time to m (20...1500) seconds, with
echo of the watchdog time. This command starts the watchdog function and must be sent within
the set watchdog time.
RESET
Switching off the device function.
START_4 Starting the device (remote) function
