Application

With key transfer systems there are two different types of disconnection:
Solenoid locking
Control interlocking
The machine is disconnected via electrical or electronic control for
example, the machine is disconnected via contactors.
Power interlocking
A load isolator must be positively switched over before releasing a key.
This ensures that the machine or system is securely disconnected from
power. This type of disconnection does not depend on auxiliary or control
circuits.
The electrical circuits built into the SAFEMASTER STS Power
Interlocking systems for both tumbler or switch systems, are suitable
for diagnostic monitoring by safety relays in Emergency stop circuits.
Disconnection errors can then be detected and faulty operation can
be prevented. In addition this forms a second channel which ensures
reliable operation in the case of a fault.
The purely mechanical designs do not feature any diagnostic functions.
They can therefore only be employed up to Performance Level (PL) c
max. It is possible by adding additional STS units or Power I=nterlocking
units with integrated electric diagnostic function to achieve Performance
Level (PL) d or (PL) e.
