The circuit diagram in easySafety only has three rungs:
Figure 203:
Example 1 "light curtain": Circuit diagram in
easySafety
The LC01I1 and LC01I2 input coils of the function block are
directly associated with the device terminals IS2 and IS3, and
the LC01QS enable contact switches the device output QS1.
The enable parameter stays in the default setting. The oper-
ating mode is changed to AST “Automatic Start”. The SUT
startup test is also activated.
The signal diagram for this application shows the depend-
ence of the enable contact LC01QS on the status of coils
LC01I1 and LC01I2:
