The signal diagram of the function block for this application
shows:
• the dependencies of the enable contact of SG01QS on the
status of coils SG01I1, SG01I2 and SG01I3.
• the interrelationship between timed out discrepancy time
SG01DT and the error output SG01ER.
• the error acknowledgement with the coils SG01I1 and
SG01I2.
• the manual re-enabling after the safety gate is closed and
the Reset coil SG01RE has dropped out.
