][Funktion_STO_Beispiel_einkanalig
The following circuit example illustrates single-channel activation of the
safety function STO.
`
The drives are switched via a safety gate.
`
Safety gates S1/S2 are monitored by a safety relay PNOZ s3.
STO single-channel with safety card
PMCprotego S2 (or when the 2nd shutdown
route is not used on the safety card
PMCprotego S1)
Safety function is activated internally via the
safety card's STO function.
The input STO1-ENABLE has no function.
The input STO2-ENABLE must be connected to
24 VDC.
STO dual-channel with safety card
PMCprotego S1
Safety function is activated internally via the
safety card's STO function
and
output STO SIL3 on the safety card is connect-
ed to STO2-ENABLE as a 2nd shutdown route.
The input STO1-ENABLE has no function.
