Safety function blocks
376
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 ES..I1 and ES..I2 directly to
the device terminals IS1 to IS14. The coils monitor the signal
of the light curtain in the safety circuit diagram. The coils
monitor the signal of the Emergency-Stop in the safety circuit
diagram.
The Reset coil ES..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.
The function block is enabled either in the safety circuit
diagram or in the standard circuit diagram by means of its
enable coil ES..EN.
