6273 Excess heat dischar dur min
The overtemperature protection function is triggered if the temperature on the
selected sensor reaches the "Overtemperature protection temperature". Contact
K11 is switched.
The overtemperature protection function ends if the temperature drops below the
"Overheat temperature protection temperature" by the switching differential entered
here.
The "Minimum overtemperature protection time" is also considered.
Define the sensor used to monitor overtemperature protection.
The overtemperature protection must operate at a minimum for the set
"Overtemperature protection time min" once started.
