7.4 Calibrating sensors
The controller is designed for connection of Pt1000, PTC and Ni1000 sensors.
− CO5->F01-1,F02-0:Pt1000
− CO5->F01-0,F02-0:PTC
− CO5->F01-1,F02-1:Ni1000
The corresponding sensor resistance values are listed in the 'Design and principle of opera-
tion' chapter.
If the temperature values displayed at the controller differ from the actual temperatures, the
measured values of all connected sensors can be recalibrated. To calibrate a sensor, the
currently displayed sensor value must be changed such that it matches the temperature
(reference temperature) measured directly at the point of measurement.
Î Activate calibration in CO5 with F20.
