Function Characteristics of the Safety System
The complete safety system consists of a TMC 66 and accompanying single beam safety
light barriers or light barriers.
After switching on of the TMC 66 via the start input, the function of the connected single
beam safety light barriers or the integrated muting controller is cyclically monitored every 2
sec.
The electrical integration into the control 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 test monitoring unit TMC 66, a selectable start- and restart interlock, as well as a
selectable contactor monitoring input are integrated.
