Safety input per EN 12453
Increased requirements on the fail-safety of the slip door
switch have been part of EN 12453 since 2001. With
EN 12453:2017 increased safety requirements (PLc, Cat.2)
also apply, for example to slack rope switches and switches
of fall protection systems, including the transmission and
processing of the signal.
With the setting MOD8 the programmable INPUT 2 allows
the evaluation of these components, which all work with an
internal resistance value of 8.2 kOhm. If a fault occurs in one
of the components, the system can no longer be operated and
the message ERROR STOP appears on the display.
1 – 4 components on a 8.2 kOhm basis can be linked
according to the following wiring diagrams. It does not matter
which of the respective switches represents the components
1 - 4 here.
* optionally
CHECK
The tolerance of the individual resistance values must not
exceed max. 1%.
