Calibrating sensors

The controller is designed for the connection of Pt 1000 sensors.
The resistance values of the Pt 1000 sensors can be found on page 112.
If the temperature values displayed at the controller differ from the actual temperatures, the
measured values of all connected sensors can be readjusted. To calibrate a sensor, the currently
displayed sensor value must be changed such that it matches the temperature (reference tem-
perature) 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.
Proceed as follows:
1. Turn the rotary switch to
Display: 0 0 0 0
2. Set valid key number [q].
3. Confirm valid key number [ ].
Display: PA_
4. Select CO5 configuration level [q].
5. Open CO5 configuration level [ ].
6. Select function block F20 [q].
7. Activate editing mode for function block F20 [ ].
8. Select appropriate sensor icon [q]:
