Coils and contacts
Function block coils initiate the functions of the function
block and monitor the connected safety transmitters.
The contacts of a safety function block confirm the enable
conditions present, selected operating modes or indicate
errors.
Coils
Connect the function block coils OS..I1 and OS..I5 directly to
the device terminals IS1 to IS14. The coils monitor the signal
of the light curtain in the safety circuit diagram.
If the coil OS..UL picks up in the safety circuit diagram, the
selection of the new operating mode is accepted with func-
tion block coil OS..SM.
The function block is enabled either in the safety circuit
diagram or in the standard circuit diagram via its enable coil
OS..EN.
If the coil OS..UL picks up in the safety circuit diagram, the
function block accepts the new operating mode with a rising
edge at the function block coil OS..SM. If it has not picked
up, the coil OS..SM has no function.
