Calibrating sensors
The connected sensors are calibrated in configuration level CO5.
The following applies:
4
CO5 -> F01 - 1 and CO5 -> F02 - 0: Pt 1000 (Pt 100) sensors (default setting)
4
CO5 -> F01 - 0 and CO5 -> F02 - 0: PTC (Pt 100) sensors
4
CO5 -> F01 - 0 and CO5 -> F02 - 1: NTC (Pt 100) sensors
4
CO5 -> F01 - 1 and CO5 -> F02 - 1: Ni 1000 (Pt 100) sensors
The resistance values of the sensors can be found on page 131.
If the temperature values displayed at the controller differ from the actual temperatures, the
measured values of all connected sensors can be changed or readjusted. To calibrate a sen-
sor, the currently displayed sensor value must be changed such that it matches the tempera-
ture (reference temperature) measured directly at the point of measurement.
Sensor calibration is to be activated in CO5 via function block F20.
An incorrect sensor calibration can be deleted by setting F20 - 0.
