N O T I C E
When using internal 24 V DC supply (terminal 12), the number of parallel inputs (terminal 37) is limited to 3, otherwise the availa-
ble output power is exceeded.
Design features
The circuit can be used up to Category 3, PL d, or SIL2.
For PL d, the complete safety functions have to be calculated (MTTFd).
Use basic safety principles.
Device used for activation of STO and safety relay must be suitable for the selected category, PL or SIL.
When implementing the emergency stop, pay attention to the following tips:
Any non-safety related standards should be fulfilled for the application and its components.
The application designer is responsible for selecting suitable components.
The cable shown as bold in Illustration 10 has to be short-circuit protected according to ISO 13849-2, table D.4.
To fulfill PL d, the MTTFd and DC for the entire safety function have to be calculated.
This setup can be used if a dual positive switching device is used. Depending on the safety relay, it is also possible to connect sever-
al activation devices to one STO.
Implementation in SISTEMA using Danfoss VLT library
As an example, use the subsystem "VLT® AutomationDrive FC 302/FCD 302 Safe Torque Off (Terminal 37)". There is no need for
editing all the parameters which are set in the library. Put the subsystem into the safety function as often as the number of drives
that are present on the single STO line.
