Wiring of the message outputs
Two message outputs are integrated in the TNT 35. Both are HIGH active, positive
switching semiconductor outputs and can be either directly connected to a PLC or control a
status display of a machine.
The message output "Safety on" is always active if the safety relay outputs are closed.
The message output "Error" is always active if the TNT 35 detects an error. Those errors
can be internal or external.
Through linking of the status outputs in the controller, the following system states can be
detected:
1. "Safety on" active, "Error" inactive
Normal operation of the TNT 35, no error detected
2. "Safety on" inactive, "Error" active
The TNT 35 detected a safety relevant failure which led to the switching off of the safety
outputs.
