i750: PTC input T1/T2 (X109): Can only be used with device variant i750 OCT for evaluating temperature sensors PTC/TKO
Frage:
What can be the reason if the evaluation of the connected PTC temperature sensor does not work, although the PTC sensor is correctly connected and parameterized?
Answer:
The evaluation of the PTC input T1/T2 (X109) is only available for i750 devices of the device variant "HIPERFACE DSL® (OCT)/PTC" for single-cable technology.
Background: Only this device variant has the required hardware circuit integrated. The device variants "Resolver" and "Multi-Encoder" lack this hardware and the existing plug-in terminals are only used for touch-proof closing of the housing.
