7.6.3.13 Heatsink monitoring OH4 (adjustable)
Purpose
Controller protection
This monitoring is designed as a warning before the disconnection of the controller via the OH-TRIP.
Thus, the process can be influenced to avoid a switch-off of the controller at an inconvenient time.
For example, fans which would cause an inacceptable noise in continuous operation, can also be
triggered.

Function
The signal OH4 is derived from a comparator with hysteresis.The threshold can be set under code
C0122. The hysteresis is fixed and amounts to 5 K. The signal is thus reset below a threshold of 5 K.
