9.6.2 Switching thresholds for multistage operation
For multistage operation, a hysteresis band about the thresholds is introduced. This
hysteresis band replaces the minimum positioning step used in multistage operation.
The band width is approx. 1 mA.
2-stage operation
Actual value Current Display / output value
Stage 1 5 mA (3...12 mA) P1
Hysteresis band 12...13 mA ---
Stage 2 15 mA (13...20 mA) P2
3-stage operation
Actual value Current Display / output value
Stage 1 5 mA (3...7 mA) P1
Hysteresis band 1 7...8 mA ---
Stage 2 10 mA (8...12 mA) P2
Hysteresis band 2 12...13 mA ---
Stage 3 15 mA (13...20 mA) P3
