3.4.7 Ground switching outputs O0- and O1-
The ground switching outputs O0- and O1- increase the shutdown protection and cross-
circuit protection of the safety system. These outputs can be used for example to switch off
a contactor connected to the PSR-TRISAFE-S safety module either via the output or via
ground.
The diagram below shows an example application: The two contactors, K1 and K2, are
switched between safe module output O0 and ground switching output O-.
Figure 3-6 Example application for ground switching outputs O0- and O1-
Ground switching output O0- can only be used in connection with output O0, ground
switching output O1- can only be used in connection with output O1.
In order to use the ground switching outputs, the corresponding parameters must be set
for outputs O0 and O1 in the SAFECONF configuration software. For more detailed
information, please refer to the online help topic "Parameterizing the I/Os of the safety
module".
