0D

Alarm levels cannot be zero for alarms that are enabled.

0E

Too many slaves in the scanner’s input data table.

0F

The FMAX and Number of Lines do not yield correct vector calculations.

10

Phase (vector) alarms prohibited with synchronous sampling and more
than 1 pulse per revolution.

11

Order-based bands are prohibited with asynchronous sampling.

12

Unsupported Sensor Type and Channel ID combination.

13

Invalid Alarm Type for the associated measurement ID.
