Safety function blocks
482
d Contact TH..QS: Closes when conditions for normal operation
present and enables the hazardous movement.
Use only in the safety circuit diagram.
e Contact TH..ER: Closes in the event of an error.
Use in the safety and in standard circuit diagram.
f Diagnostics output TH..DG: Provides information on the states
of the function block.
Evaluation only in the standard circuit diagram with the diag-
nostics function block DG.
Wiring of the function block
The relay uses different coils and contacts.
Wire its coils TH..I1 to TH..I4 directly to the device terminals
IS1 to IS14. Example of a 2-channel function block:
IS01---------------------------Ä TH01I1
IS02---------------------------Ä TH01I2
IS06---------------------------Ä TH01I3
IS08---------------------------Ä TH01I4

Make-break combinations are used as 2-channel two
hand buttons. The following fixed assignment between
the function block inputs and the two hand button must
therefore be observed:
• Button 1a: make contact to TH..I1
• Button 1b: break contact to TH..I2
• Button 2a: make contact to TH..I3
• Button 2b: break contact to TH..I4
You can associate the function block contact TH..QS directly
with one or several of the safety device outputs, for example:
