Safety Basic Monitor
Product Description
4.3 Safety relevant data
To determine the safety characteristics (PFD and PFH), the values of all compo-
nents using this function are to be considered. The module provides no significant
contribution to the PFD or PFH values of the complete system. For the values of
other components, please refer to relevant documentation.
4.4 Requirements for the voltage supply +24 V

Attention!
If the option „augmented reliability“ is selected the response time can extend.
Attention!
Error states of the remote outputs used in the safe configuration can be eliminated by
starting and stopping the monitor.
Information!
The externally connectable circuits are to be separated from the net absolutely reliable!
