Controlling the safety functions
5.2 Control of "STO" and "SS1" via terminal module for option K82
Figure 5-5
A switch according to ISO 13850, positive opening according to IEC 60947-5-1 or a certified
safety control must be used as actuating element.
Note
Terminal -X41:10 is permanently connected to digital input DI 7 of the Control Unit.
Interconnection in groups
When using a single actuating element for multiple cabinet units, the following terminals
have to be used on terminal strip -X41:
• -X41:2: Interconnection to the next cabinet unit, terminal -X41:1
• -X41:4: Interconnection to the next cabinet unit, terminal -X41:3
• -X41:8: Interconnection to the next cabinet unit, terminal -X41:7
Wiring
The control cables should be permanently routed (e.g. cable duct, retained using cable ties).
Signal cables and encoder cables should be installed separated from one another.
The shields of the control cables should be grounded through the largest possible surface
area immediately after they enter the control cabinet.
Outside the control cabinet, the cables must be routed in such a way that they are safe to
walk on (e.g. as specified in IEC 60204-1).
