Basic Data
Safety and Electromagnetic Compatibility (EMC)
The systems comply with the standards and directives mentioned in the appli-
cable CE declaration.
Please take note of the following safety measures:
Do only connect the system to an earthed mains power
socket of 230 V, 50 Hz.
Do not place hot blocks on inflammable or not heat-resistant
surfaces.
Make sure to only use containers in the block which are suit-
able for the desired temperature range.
If liquid gets into the system, immediately pull out the plug
and contact our service department to ensure complete
safety.
Please do not touch or transport hot systems.
Contact with highly flammable fluids must be avoided.
The ventilation of the device must not be blocked. To ensure
the proper ventilation at all times please consider a mini-
mum distance of 10 centimeter on each side of the device.
Damaged mains cable should only be replaced with equal
ones.
Warranty
All functions of the systems have been tested thoroughly. After that, the sys-
tem and the accessories were packed carefully in perfect condition.
If, however, any damages or defects are detected during installation or setup,
please inform DITABIS immediately (see our Terms and Conditions at
www.ditabis.de).
If used under normal laboratory conditions according to the Operating Manu-
al, DITABIS grants a warranty of 1 year for the material and workmanship,
starting with the day of shipment.
Disclaimer of warranty
In case of unspecified use of the device, the manufacturer assumes no re-
sponsibility.

Important Information
This manual complies with the standards and directives mentioned in the EN
DIN 61010-1 Norm. IQ, OQ and PQ documents are available on request.
The systems are provided with a high-precision self-optimising
temperature controller. Due to the self-optimisation it might oc-
cur that the set temperature is exceeded in individual cases.
Please note, that by heating your samples dangerous gases may
be emitted. In this case, the device must be used with an extrac-
tor hood.
If the ThermoMixers are operated with a high shaking frequency,
the vibrations of the system might transmit to the underground.
Please do consider this when placing the system.
Contact with highly flammable liquids must be avoided. The ex-
changeable block may be hot.
The ventilation of the device must not be blocked. To ensure the
proper ventilation at all times please consider a minimum
distance of 10 centimeter on each side of the device.
Environmental conditions
The ideal area of operation of the devices is achieved at 80% relative air
humidity at most and lays between +3°C - +50°C ambient air temperature.
This values should not be under run or exceeded.

Temperature accuracy
Every HLC by DITABIS system is calibrated with a gauged high-precision tem-
perature measuring device to temperature accuracy and reproducibility. This
process is performed at a room temperature of +20°C and a block tempera-
ture of +37°C. The absolute calibration of the heating unit can also be per-
formed for a certain temperature range if the customers desires. HLC by
DITABIS reaches a very high accuracy by measuring the block temperature
directly inside the block. It can, however, not be avoided that the cold room
temperature affects the sample temperature in case of high a large tempera-
ture difference between room and block temperature. The anti-condensation
plate reduces this effect. We recommend using the anti-condensate plate BA
24 / BA 96 or the tempering tub BT 01 / BT 02, if high temperature accuracy in
the sample is required.
When setting a process time, please note that the sample temperature is
always reached a little later than the displayed block temperature.
First Steps
Setup
Plug the mains cable in the IEC socket on the back of the system and connect
it with the mains power 230 V, 50 Hz via a Schuko socket.
Changeable blocks
At delivery, the changeable blocks are packed separately. Place the blocks on
the tempering plates and take care of the proper alignment of the central
threaded bolt and the two small corner bolts ensuring that the block lays
accurately on the tempering plate. Then attach the block with the short sock-
et screw tightly at the bottom of the tempering plate to get the block fixed for
shaking and to obtain even better temperature accuracy.
Check the tight attachment of the block by pulling it up. If it loosens, please
use the longer screw.
Never start the process without the block being tightly attached.
Do always use two blocks for two-block systems, even if only one
of them is used. This ensures safety as well as a smooth shaking
operation.

Assembly of Accessories
Anti-Condensation Plate BA 24 / 96 (800012900 / 800013000)
The anti-condensation plate BA 96 (800013000) is placed on the attached
block, no assembly steps are required.
For using the anti-condensation plate BA 24 (800012900), remove the socket
screw in the block with the enclosed screwdriver. Screw the enclosed thread-
ed pin with isolation knob into the anti-condensation plate. Place the anti-
condensation plate on the block and screw the threaded pin in deeper so that
it takes hold of the bolt of the system and with that tightly attaches block and
anti-condensation to the system.
Data Transfer
A USB 1.1. interface for the communication with a PC is provided as a stand-
ard. Connect the system via the USB-port on the left side with a USB-cable to
your PC. If this is not available at your computer, install the suitable USB-
driver. You will find it under www.ftdichip.com/Drivers/VCP.htm). These USB-
drivers generate a new virtual COM-interface in your PC. The chip in the Smart
Control is called FT232B.
Access process data via USB
Start a terminal program (e.g. Hyper terminal) on your PC.
This program you will find under Windows in "Programs" / "Accessories" /
"Communication". The window "Hyper Terminal" is opened. Proceed system-
atically, please note that for the connection setting for "Bits per second"
115200 is selected.

STOP
Enter process data via USB
For the process control of a HLC system with Smart Control via a USB-
interface, four commands are possible and required:
Start

15
Starts a process without program with the parameters indicated on the dis-
play.
Time settings, if applicable, are deleted and overwritten by continuous since
time settings must be programmed on the computer.
Stop
Stops all processes and returns to the start menu, running programs / pro-
cesses are aborted.
t=0370
Changes the set temperature to a new value.
The temperature must always be entered with four digits.
t=0370 sets 37.0°C, t=0050 sets 5.0°C, t=-060 sets -6.0°C.
t= is the identification for a temperature value. The associated numerical
value reflects the value in tenth of a degree.
The first digit after the = can be a 0, a 1 or a hyphen. Invalid temperature
values are - like for the input at the system - replaced by the next valid value.
r=020
Changes the set rotational speed to a new value.
The rotational speed must always be entered with three digits.
r=120 sets 1,200 1/min, r=045 sets 450 1/min.
r= is the identification for a rotational speed value. The associated numerical
value reflects the value in 10 1/min.
Invalid rotational speed values are - like for the input at the system - replaced
by the next valid value.
r=000
Stops the rotational speed, e.g. if shaking should be stopped but tempering be
continued.
Other inputs like e.g. r=0 are interpreted as rotational speed and cause the
motor to rotate with the minimum rotational speed.
Every command must be confirmed with "CR"
In case of unknown commands and/or in case of spelling errors, nothing is
done.
The inputs in the setup menu like colour, contrast and brightness of the dis-
play, language, rotation direction etc. can only be done at the operating panel
of the system itself.

16
Troubleshooting
The display remains blank
Please check if the mains switch on the back side is switched on.
If it is switched on but voltage is present at the socket, check the micro-fuse
and replace if required. (IEC 127-2/III, 250 V, 2 A time-lag).
This fuse - and a spare fuse - are located in the IEC-bushing (in which the con-
nection cable is plugged). The fuse box can be pulled out with a screwdriver.
The system does not cool, heat or shake as set
Check whether the display indicates the correct system type name at power-
on. If not, please contact the HLC by DITABIS service department.
There are excessive temperature fluctuations
Check the seat of the changeable block by pulling it up. If it is too loose or if
the block exhibits roughness, e.g. contamination, the heat/ coolness is not
transferred correctly.
Information on the capacitive touch display
The touch display reacts on finger pressure, even when wearing thin latex
gloves, but not on stylos.
Due to its glass surface, the front panel is insensitive to dirt, chemicals and
mechanical damage. Please avoid scratches in the coating since they can
cause malfunctions. Please take note of the following cleaning instructions.

17
