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:

Pt100/LiBus module (small cover), catalog no. LRZ 918

Pt100/LiBus module (large cover), catalog no. LRZ 925

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
