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 SG..I1 and SG..I3 directly to
the device terminals IS1 to IS14. The coils monitor the signal
of the light curtain in the safety circuit diagram. Monitor the
signal of the door switch and guard locking in the safety
circuit diagram.
The reset coil SG..RE resets the function block in the Manual
Start (MST) and Controlled Start (CST) mode and the starts
of normal operation. Used in the safety circuit diagram.
The function block is enabled either in the safety or in the
standard circuit diagram with its enable coil SG..EN.
Contacts
In the safety circuit diagram, the contact SG..QS enables the
hazardous movement. It closes as soon as the contacts of the
gate switches are closed (with AST operating mode). If moni-
toring of the guard locking is required, the contact SG..QS
closes if the gate switches are closed and the guard locking
is active.
If you wire the contact SG..ER in the standard and/or safety
circuit diagram, it indicates the presence of an error by
closing.
