Safety data
The FPTC-02 module is a type A safety component as defined in IEC 61508-2. For the
types of the drive/inverter STO and the FSO module, see the applicable hardware
manual or FSO user's manual.
The table gives the safety data for the SMT function with different configurations.
The calculations are based on the worst case data of the drive Safe torque off (STO)
function. The PFH/PFD
of the FSO module. The FSE-31 module is included in the calculations for the FSO
module.
Note: The failure rate of the PTC sensor is not included in the calculations.
These are the configurations in the table:
1.
FPTC module + drive STO, two-channel configuration. See
1 (page
30).
2.
FPTC module + drive STO + FSO module with STO function request, two-channel
configuration. See
3.
FPTC module + drive STO + external safety relay, two-channel configuration. See
Wiring example 3 (page
4.
FPTC module + drive STO, one-channel configuration. See
4 (page
33).
5.
FPTC module + drive STO + FSO module with STO function request, one-channel
configuration. See
values can be different based on the internal configuration
