Action against high-frequency interference
High-frequency interference can be caused by out-of-phase switching operations. If such interference
occurs and results in sporadic failure, we recommend taking the following action to suppress interference:
n
Provide inductive loads with RC combinations as per manufacturer's specifications.
n
Route the connecting cable to the temperature sensor separately from power lines.
n
Increase the distance from sources of interference.
n
Check the shield connection on the temperature sensor.
n
Suppress HF interference using hinged-shell ferrite rings.
