7.7.3.6 Motor temperature monitoring OH7 (adjustable)
Purpose
Process monitoring
This monitoring is designed as a warning before the disconnection via the OH3-TRIP.
Thus, the process can be influenced to avoid a switch-off of the motor at an inconvenient time.
For example, blowers which would cause an inacceptable noise in continuous operation, can also
be triggered.

Function
The signal OH7 is derived from a comparator with hysteresis.
Here, the same conditions apply as for the OH3 monitoring, since here the same inputs are used.
The threshold is set under code C0121. The hysteresis is fixed and amounts to 15 K. The signal is
thus reset below a threshold of 15 K.
