Prerequisites for competent persons:
– They have a suitable technical education.
– They are familiar with the rules and regulations for occupational safety and
safety at work.
– They are familiar with the original operating instructions of the device.
– They have been instructed by the responsible person on the mounting and
operation of the device.
Certified electricians
Electrical work must be carried out by a certified electrician.
Due to their technical training, knowledge and experience as well as their familiar-
ity with relevant standards and regulations, certified electricians are able to per-
form work on electrical systems and independently detect possible dangers.
In Germany, certified electricians must fulfill the requirements of accident-preven-
tion regulations BGV A3 (e.g. electrician foreman). In other countries, there are re-
spective regulations that must be observed.
Disclaimer
Leuze electronic GmbH + Co. KG is not liable in the following cases:
– The device is not being used properly.
– Reasonably foreseeable misuse is not taken into account.
– Mounting and electrical connection are not properly performed.
– Changes (e.g., constructional) are made to the device.
Overview
You can replace a safety sensor from the RS4 series with a RSL 410 or RSL 420
safety sensor with the CU411-RS4 connection unit without needing to change the
wiring of the application. The connection unit has a RS4 compatible SUB-D 15
connector.
Functions
The functions of the RS4 are reproduced by the functions of the RSL 410/
RSL 420. Please note that the functions of the RSL 410/RSL 420 are defined if
necessary unlike the RS4, e.g. the timing.
If the RSL 410/RSL 420 detects the CU411-RS4 connection unit, the RS4 com-
patible coding is used for the field pair selection. Example: The field pairs 1 ... 8 of
the RS4 are coded as field pairs A1.1 ... A1.8 of the RSL 410/RSL 420.
The functionality of the RSL 410/RSL 420 is restricted by the reduced number of
switching input/output of the CU411-RS4 connection unit. The following RSL 410/
RSL 420 functions are not available:
– EDM
– Second protective function
– Changeover enable
– Changeover monitoring
– E-Stop/OSSD linkage
– Change the configuration banks
– More than eight protective fields
