Function and Commissioning of the TNT 35
4.1
Function characteristics of the safety system
The complete safety system consists of a TNT 35 and accompanying protective photoelec-
tric sensors or light barriers.
After the TNT 35 is switched on via the start input, the functionality of the protective
photoelectric sensors is monitored in two-second cycles.
The electrical integration into the controller has to be performed acc. to the corresponding
safety category acc. to ISO 13849-1. The voltage free safety relay outputs can be directly
used for shut-down of the dangerous movement.
Inside the monitoring unit TNT 35, a selectable start- and restart-disable, as well as a
selectable relay monitoring input are integrated.
4.1.1
Display and Operating Instruments
The test monitoring unit TNT 35 features integrated LEDs to indicate the state of the
system.
The start- and restart-disable, as well as the relay monitoring functions are set on the
TNT 35 using the corresponding jumpers on the connection terminals.
