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
The EM..OC function block coil is used to start the moni-
toring function of the function block.
You can address the coil, for example, with an Enable
contact of a different safety function block.
The EM..FL function block coil monitors the signal of the
feedback loop in the safety circuit diagram.
The Reset coil EM..RE resets the function block in Manual
Start (MST) and Controlled Start (CST) operating modes and
starts normal operation. It is used in the safety circuit
diagram.
