Setting possible
This monitoring function sends a warning before the controller is switched off because of a TRIP (OH)
using the function “Heatsink temperature (fixed)”.
•
Thus, the process can be influenced to avoid a switch-off of the controller at an inconvenient
time.
•
Additionally, fans which would cause an unacceptable noise in continuous operation, can also
be switched on and off.
MCTRL_bKuehlGreaterC0122_b
is derived from a comparator with hysteresis.
