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 Ä Chapter 7.2.1
"Read commands" on page 20 and Ä Chapter 7.2.2 "Write commands"
on page 21.
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.
