7.20.6 Example for the Offset:
Sensor range: 20mA
≙ 10 bar
Required value: 5 bar
Level 1:
20% of the 2 nd additional input
Level 2: 80% of the 2 nd additional input
Intensity 1:
-10% ≙ -1 bar (refer to the required value)
Intensity 2: +30% ≙ +3 bar (refer to the required value)
The Level 1 have to be entered on the axis of the “additional input” in percent of this
Second Additional input (=20%). Also proceed with the second level (80%).
Intensity 1 and 2 are depending on the Sensor range of the actual value signal.
The offset of Intensity 1 is valid till Level 1. After reaching Level 1 the Required Value has
no offset. Therefore you have to enter the Intensity 1 at the 0%-axis to fine the right offset
value.
The Required Value is valid till you reach the Level 2. After reaching Level 2, the new value,
is influenced by the offset of Intensity 2. To get the right offset after Level 2, you have to
enter the Intensity 2 at the 100%-axis of the additional input.
