•
Sensor “OK” current / voltage range
The Sensor “OK” current / voltage range can be specified either as voltage or current range
depending on the selected sensor type (see
For example, for applications using a TQxxx/IQSxxx proximity measurement chain as the
sensor input (Sensor type: 2-wire current), the recommended Sensor OK current range is
15.5 to 20.5 mA.
•
Bad pulse window
Internally, the SpeedSys300 ODS301 module implements redundant pulse detection
circuitry, in order to allow self-diagnosis. If two or more differences between the two
redundant channels are observed within the time frame of the ‘Bad pulse window’ parameter,
a "bad pulse error" is raised for the duration of the Bad pulse window (see the image below).
