Configurable functions
This section describes the functions of the UE4155 bus node which are selectable via soft-
ware. Chapter 6 “Examples of circuits” on page 33 describes several typical applications
that you can realise with the aid of the functions described below.
Test the protective device after any changes!
Changes to the configuration of the devices can degrade the protective function. After eve-
ry change to the configuration you must therefore check the effectiveness of the protective
device. To this end, please observe the notes in chapter 7.3.4 “General acceptance of the
bus node” on page 38.
The person who makes the change is also responsible for the correct protective function of
the device. When making configuration changes, please always use the password hierar-
chy provided by SICK to ensure that only authorised persons make changes to the configu-
ration. The SICK service team is available to provide assistance if required.
When starting to configure the device, you may save an application name with a maximum
of 22 characters. Use this function as a “memory jog”, e.g. to describe the application of
the current device configuration. Device symbol
