Information about the PT100 logic function:
All sensor inputs, which are recognised by the switch position PT100 logic, have the in the
following described function. The relays of the respective channels are equipped with a logical
combination with the active sensor. So if for two channels the logical function is active, the
adjusted thresholds are valid for both channels. The relay switches on, if the temperature of
PT100(1)
OR
PT100(2) is higher than the adjusted temperature. It switches off, if the
temperatures of PT100(1)
AND
PT100(2) are lower than the adjusted temperature. This logical
operation can be done with all of the four sensors in any combination.
