• Range C: Compare I1 with Offset greater than I2
– This example behaves as described in Range A. The offset value is added to the actual value.
– Comparison I1 equals I2
The contact switches on:
– If I1 is equal to I2, i.e. the actual value is equal to the setpoint value.
The contact switches off:
– If the hysteresis limit is exceeded with the actual value rising.
– If the hysteresis limit is undershot with the actual value decreasing.
• Range D: I1 with offset leaves the permissible value range. The contact CY closes.
CY opens as soon as I1 with offset is once more within the value range.
