Calibrating sensors
The connected sensors are calibrated in configuration level CO-SYS.
The following applies:
4
CO-SYS -> F02 - 1: Pt 1000 sensors (default)
4
CO-SYS -> F02 - 0: PTC sensors
The resistance values of the sensors can be found on page 91.
If the temperature values displayed on 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 to match a temperature (reference
value) measured directly at the point of measurement.
Activate the sensor calibration in CO-SYS over function block F08.
An incorrect sensor calibration can be deleted by setting F08 - 0.
Proceed as follows:
Turn rotary switch “Configuration and parameterization“ to
