Application and Wiring Examples for Safety Modules
When the module is wired as shown, it is suitable for applications that are rated
up to, and including,
Category 4
and
PLe
as defined in ISO 13849-1. To achieve
that suitability rating, you may have to perform diagnostic testing of the safety
function.
One diagnostic test method is to configure the safety input channel for Safety
Pulse Test to test the circuit for short circuits to 24V DC. Safety input pairs must
be associated with different Test Output sources.
