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
You connect the function block coils TH..I1 to TH..I4 directly
to the device terminals IS1 to IS14. They monitor the signal
of the two hand circuit in the safety circuit diagram.
The function of the function block is enabled either in the
safety or in the standard circuit diagram with its enable coil
TH..EN.
Contacts
In the safety circuit diagram, the contact TH..QS enables the
hazardous movement. It closes if the two hand button is
actuated correctly.
If you wire the contact TH..ER in the standard and/or safety
circuit diagram, it indicates the presence of an error by
closing.
