The above circuit operates as described in example 1. The
signal light is triggered at Q4 for additional overload
monitoring. If Q4 has an overload, it would “pulse”.
Example 3: Automatic reset of error signal
Figure 194: Automatic reset of error signal
The above circuit diagram functions in the same way as
Example 2. In addition the marker M16 is reset every 60
seconds by timing relay T08 (on-delayed, 60 s). Should I16
remain at 1, M16 will continue to be set. Q1 is set briefly to 1
until I16 switches off again.
