Function description for Fig. 15.7-1
1. Activate the threshold 45 Hz K1 in PAR1.
2. If K1 remains picked up, K 2 is conne cted.
3. Compressor 2 is connect ed via K3. At the same time the parameter set is changed via X3/E2 (process controller is not affected)-
4. K1 picks up when the minimum frequency is reached (depending on load). After time K1T is over, K2 picks up again.
5. Compressor 2 is switched off. The parameter set is changed backed to PAR1.
• K1T debounces the switching point of compressor 2 (adapt delay time to process).
