1 General
Many types of LAUDA constant temperature equipment have vacant
module slots for installing additional interfaces. The number, size and
arrangement of the module slots vary depending on the device and are
described in the operating manual accompanying the constant temperature
equipment. Two additional module slots available as accessories can be fitted
to a LiBus module box, which is then connected as an external casing to the
LiBus interface on the constant temperature equipment.
This operating manual describes how to install and configure the following
interface modules:
Contact module with single input and output (NAMUR), catalog no.
LRZ 914
Contact module with 3 inputs and outputs, catalog no. LRZ 915
The contact interface is used to set or query binary states of the constant
temperature equipment by opening and closing circuits. The module acti-
vates when states are output (read). When the states change (write), the
user opens or closes the circuit outside the module. The interface func-
tions provided for this purpose are described in chapters ÄChapter 7.2.1
“Read commands” on page 20 and ÄChapter 7.2.2 “Write commands”
on page 21.
1.1 Intended use
The interface module can only be operated as intended and under the
conditions specified in this operating manual.
The interface module is an accessory that increases the connections options
of LAUDA constant temperature equipment. It may only be installed in con-
stant temperature equipment that supports the interface provided. Refer to
the chapter "Compatibility” in this operating manual for a list of compatible
product lines.
Operation of the interface module is also permitted in combination with the
LiBus module box (LAUDA catalog no. LCZ 9727). This operating manual
also contains a description of how to install and connect up the module box.
Operation after incomplete assembly
Operation on incompatible constant temperature equipment
Operation using cables or connections that are defective or do not
confirm to standards
Reasonably foreseeable improper use

1.2 Compatibility
The interface modules are available as accessories for the following LAUDA
product lines:
ECO
Integral XT
Integral IN
PRO
Proline
Variocool
Variocool NRTL
Operating interfaces of the same type
Only one contact interface can be used for each item of constant
temperature equipment. This applies irrespective of the interface
type.
1.3 Technical changes
All technical modifications are prohibited without the written consent of the
manufacturer. Damage resulting from a failure to observe this condition will
void all warranty claims.
However, LAUDA reserves the right to make general technical modifica-
tions.
1.4 Warranty conditions
LAUDA grants a standard warranty of one year.

2 Safety
2.1 General safety information and warnings
Read this operating manual carefully before use.
Keep the operating manual in a place within easy reach of the interface
module.
This operating manual is part of the interface module. If the interface
module is passed on, the operating manual must be kept with it.
This operating manual is applicable in combination with the operating
manual of the constant temperature equipment in which the interface
module is installed.
Manuals for LAUDA products are available for download on the
LAUDA website: https://www.lauda.de
The warnings and safety instructions in this operating manual must be
observed without fail.
There are also certain requirements for personnel, see ÄChapter 2.3
“Personnel qualification” on page 8.

2.2 Information about the interface module
Always disconnect the constant temperature equipment from the power
supply before installing the interface module or connecting interfaces.
Always take the recommended safety measures against electrostatic
discharge before handling interface modules.
Avoid touching the circuit board with metallic tools.
Do not start up the constant temperature equipment before installation
of the interface module is complete.
Store any unused interface modules in their packaging in accordance
with the specified ambient conditions.
Use only suitable cables of sucient length for cable connections.
Make sure that the protective screen on the cables and connec-
tors complies with EMC regulations. LAUDA recommends using pre-
assembled cables.
Always lay cables correctly so that they do not pose a tripping hazard.
Secure the laid cables and make sure that they cannot be damaged
during operation.
Check the condition of the cables and interfaces prior to each opera-
tion.
Immediately clean any soiled parts, in particular unused interfaces.
Make sure that the signals transmitted via the interface correspond to
the permitted operating parameters of the interface module.
2.3 Personnel qualification
Only specialized personnel are permitted to install interfaces modules. Spe-
cialized personnel are personnel whose education, knowledge, and experi-
ence qualify them to assess the function and risks associated with the device
and its use.

3 Unpacking
DANGER!
Transport damage
Electric shock
Closely inspect the device for transport damage prior to
commissioning!
Never operate a device that has sustained transport
damage!
NOTICE!
Electrostatic discharge
Material damage
Always observe safety measures against electrostatic dis-
charge.
Please observe the following installation sequence:
1. Remove the interface module from its packaging.
2. If you want to store the interface module at the installation location,
use the outer packaging. This packaging is protected against static
charging.
3. After installing the equipment, dispose of the packaging materials in
line with environmental regulations, see Ä“Packaging” on page 26.
If you discover any damage on the interface module, contact
LAUDA Service immediately, see ÄChapter 1.6 “Contact
LAUDA” on page 6.

4 Device description
4.1 Purpose
The contact module is used to set or query binary states of the constant
temperature equipment by opening and closing circuits:
Output state (read): The module activates the circuit of the defined
interface function, see ÄChapter 7.2.1 “Read commands” on page 20.
Set state (write): The user activates the circuit of the defined interface
function from outside the module, see ÄChapter 7.2.2 “Write com-
mands” on page 21.
4.2 Versions
Choosing the most suitable version depends entirely on the scope of control
required:
Contact module with single input and output (NAMUR): One switching
function and one query can be configured for one input and one output,
which is enough to switch the constant temperature equipment between
operating and standby mode as well as monitor the temperature, for
example.
Contact module with 3 inputs and outputs: There are three inputs and
three outputs to which you can assign various switching functions and
queries.
Only one of the two versions can be operated for each item of
constant temperature equipment. This is particularly important to
note when integrating additional modules via the module box.
4.3 Structure
Contact output ( OUT ) and contact input ( IN ) on interface module
LRZ 914 are implemented using two 3‑pin connections.
1 Cover with holes for M3x10 fastening screws
2 Contact output, connector, 3-pin
3 Contact input, socket, 3-pin
Refer to ÄChapter 6.1.1 “Contact module with single input and output
(NAMUR)” on page 15 for more information on contact assignment.
