1.8 Requirements for the heat transfer liquid
nHeat transfer liquids are used to control the temperature. LAUDA heat
transfer liquids are recommended for the constant temperature equip-
ment. LAUDA heat transfer liquids have been tested by the company
LAUDA DR. R. WOBSER GMBH & CO. KG and approved for this
device.
nThe heat transfer liquids are suitable for a specific temperature range.
This temperature range must correspond with the temperature range of
your application.
nHazards caused by high or low temperatures or fire may arise during
operation if the heat transfer liquid exceeds or falls below certain tem-
peratures or if the container ruptures causing a reaction with the heat
transfer liquid.
nThe safety data sheet of the heat transfer liquid specifies hazards and
the corresponding safety measures required for handling the liquid. The
safety data sheet of the heat transfer liquid must therefore be observed
to ensure proper use of the device.
nIf you wish to use your own heat transfer liquids, check to ensure that
the fluids are compatible with the materials used.
nThe heat transfer liquid must be provided with corrosion protection.
1.9 Materials
All parts that come into contact with heat transfer liquid are manufac-
tured from high-quality materials adapted to withstand the operating tem-
perature. High-quality stainless steels, copper, brass and premium-quality
heat-resistant plastics are used.

3.4 Functional elements
3.4.1 Hydraulic circuit
The hydraulic circuit refers to the circuit that the heat transfer liquid flows
through.
The circuit essentially consists of the following components:
nInternal expansion bath with heat transfer liquid
nSubmersible pump for conveying the heat transfer liquid to the external
consuming unit via the pump connections
nAdjustable bypass with pressure gauge for adjusting the pump pressure
to the requirements of the external consuming unit.
nCooling coil in the bath boiler for cooling the heat transfer liquid
nHeater in the bath boiler for heating the heat transfer liquid (the heater
is potential equipment)
You will find further information on the technical data for the pump
in ÄChapter 11.4 “Filling volume and characteristics of the
pumps” on page 85.
Fig. 5: Pressure gauge
V08Variocool18 / 97

3.4.2 Cooling unit
The cooling unit consists of the following main components:
nCompressor
The compressor is equipped with a motor protection switch which reacts
to the temperature and current consumption of the compressor.
nCondenser
An air-cooled or water-cooled condenser is used in the cooling unit
depending on the device type. The heated air is discharged to the envi-
ronment in air-cooled condensers. Fresh air is drawn in through the
front of the device by means of a fan, heated and then discharged at the
back of the device for this purpose. The heat is dissipated via the cooling
water circuit in the case of water-cooled condensers.
nEvaporator
Heat is dissipated via a tube coil evaporator in the internal bath.
You will find technical data on the cooling unit in ÄChapter 11.2
“Cooling capacity” on page 84.
3.4.3 Interfaces
A general overview of the standard interfaces and the optional interface
modules of the device can be found in the following sections.
The equipment connected to the low-voltage inputs and low-voltage
outputs must have safe separation from dangerous to touch
voltages according to DIN EN 61140 such as by the use of
double or reinforced insulation according to DIN EN 60730-1 or
DIN 60950-1.
The installation of these additional interface modules is described
in these operating instructions. Further information regarding wiring
and the use of these interface modules is provided in the separate
operating instructions for the interface modules. The respective
operating instructions must be consulted regarding appropriate use.
The devices are equipped with a USB interface (type B) as standard. This
interface enables connection to a PC. Software updates are installed on the
device via this interface (only for updaters, no process interface).
The devices are equipped with an alarm output as standard equipment. This
changeover contact is switched if the device changes to the standby state or
if an alarm is triggered. Reverse flow protection can be activated in this way
or faults can be registered on a system.
USB interface
Alarm output
V08 Variocool 19 / 97

Devices can be supplemented with additional interface modules.
nThe analog module (catalogue number LRZ 912) has a 6-pin socket with
two inputs and two outputs. The inputs and outputs can be configured as
a 0 – 20 mA, 4 – 20 mA or 0 – 10 V interfaces independently of one
another. A voltage of 20 V applied to the socket supplies power to an
external sensor with electronic evaluation unit.
nThe RS 232/485 interface module (catalogue number LRZ 913) is
available in a 9-pin SUB-D socket design and is galvanically isolated
by an optocoupler. The RS 232 interface can be connected directly to
the PC using a 1:1 contacted cable. The LAUDA command set makes
the interface module compatible with the product lines ECO, Variocool,
Proline, Proline Kryomat, PRO, Integral XT and Integral T.
nThe contact module (catalogue number LRZ 914) is available in a plug
connector design according to NAMUR NE28. This contact module is
identical to LRZ 915, but only has two sockets, each with one output and
one input. The coupling socket (catalogue number EQD 047) and the
coupling connector (catalogue number EQS 048) have a 3-pin design.
nThe contact module (catalogue number LRZ 915) is available in a 15-
pin SUB-D socket design. The module has 3 relay contact outputs
(changeover contacts, maximum 30 V/0.2 A) and 3 binary inputs for
control via external potential-free contacts.
nProfibus module (catalogue number LRZ 917). Profibus is a bus system
used primarily in the chemical industry, which can connect a maximum
of 256 devices at a high signal transmission rate.
nPt100-/LiBus module (catalogue number LRZ 918). An external tem-
perature probe can be connected to the Pt100 interface of the module.
The Command remote control can be used with the constant tem-
perature equipment via the LiBus interface. A solenoid valve for cooling
water control, reverse flow protection or a Through-flow cooler can, for
example be connected in this way.
nLiBus module (catalogue number LRZ 920). The Command remote
control can be used with the constant temperature equipment via the
LiBus connection. It is also possible to connect additional modules (such
as the LRZ 918, but without Pt100 interface). A solenoid valve for
cooling water control, reverse flow protection or a flow through cooler
can, for example be connected in this way.
nEthernet USB module (catalogue number LRZ 921). The module pro-
vides the customer with the opportunity to monitor and control ther-
mostatic regulation processes that are performed with a LAUDA con-
stant temperature equipment via Ethernet using the LAUDA interface
command set.
An additional function of the module is remote maintenance of the
LAUDA constant temperature equipment via Ethernet.
Currently, the USB interfaces of the module are not functional.
nEtherCAT module (catalogue number LRZ 922) with M8 connection
sockets. EtherCAT module (catalogue number LRZ 923) with connec-
tion via RJ45 sockets. EtherCAT is an Ethernet-based field bus with
master/slave functionality.
Refer to the operating manual accompanying the relevant LAUDA interface
module for further information on connecting and using these interfaces.
