function of these contactors, each relay block must have at least one
normally closed contact which is fed back in series to the corresponding
terminal of the MSR41 base module.
Output monitoring: The signal at the corresponding input terminal
must be high before the start button is pressed (this means: the normally
closed contacts of the external relays must be closed before allowing a
start).
It must be noticed, that surge suppressors may drastically increase the off
delay time of the contactors. Diodes are not allowed to be used as surge
suppressors, for exactly this reason.
Recommended surge suppressors are:

The MSR41 module has to be tested periodically – in accordance with
valid regulations - by qualified and trained personnel to discover
prohibited manipulations or unauthorized modifications.

The MSR41 Modules can only be removed, when the machine or the
equipment is shut down completely and can no longer be operated
without tools. If a controller has to be disposed, it can be simply
dismantled. The separated materials can be recycled according to state of
the art technology and corresponding regulations of the country it was
used in.
Product labels
All the necessary safety information can be found on the product labels,
which can be found on every controller module (example):

cal Data
1. In cases where the MSR41 base module
is installed without expander modules
the function output monitoring must
always be realized, the only exceptions
are if the PNP outputs are connected with
another safety relay or a safety PLC.
2. Through the use of output monitoring,
it is possible to switch external “power”
contactors within the safety circuit. Such
contactors often deal with large inductive
loads, which during the switching off
phase can create large potential peaks.
For this reason surge suppressors are
highly recommended. Surge suppressors
must be connected parallel to the
external contactors (e.g. Figure 1). They
may never be connected parallel to the
contacts of a MSR45E expander module.
