5.5.21 Sensor curves
Background of the sensor calibration
To correct measuring error of each analog input (pressure, temperature, level, etc.) calibrating constants should
be set. Calibration is made by adding the value of setpoint CU AIN1 Calibration (page 351), or CU AIN2
Calibration (page 352), or CU AIN3 Calibration (page 352), or CU AIN4 Calibration (page 353) directly to
the calculated value at analog input.
Note: The calibration must be done at the operational point of the analog input (e.g. 80°C, 4.0Bar etc..)
Default sensor curves
There are 16 default resistive curves available. The following table provides information on minimum/maximum
values of respective sensors. Actual values especially of temperature curves may differ. Meaning is to prolong
curve to the lower temperature values, so the cold engine will not raise alarm fail sensor.
