Table 9 Failsafe Faults
If upon request temperature compensated remote position sensor reading is
outside of range in degrees or internal position sensor reading is outside of range in
degrees for five reads in a row. Indicates a slipping or blocked sensor.
If, upon request, temperature compensated temperature sensor reading is outside
of range in °C for five reads in a row. Indicates environment temperature is too hot/
cold.
Internal serial bus fault. Indicates a hardware problem - may require replacing the
positioner.
If an FRAM record and its copy both have CRC errors (as detected by read on
initialization,) OR if the temperature calibration table has not been written in its
entirety (detected by a CRC of column CRCs) OR bad FRAM signature. Indicates a
hardware problem- may require replacing the positioner.
If temperature compensated reference voltage is out of range for five reads in a row,
or if the raw reading is outside the range
problem- may require replacing the positioner.
If temperature compensated pressure sensor 4 (pilot) reading is outside of range.
Indicates a hardware problem - may require replacing the positioner.
A valid hidden record (in RAM) existing upon reset indicating that a fatal event
(watchdog, illegal interrupt, stack overflow, data checksum) occurred twice in a row.
Indicates a hardware problem - may require replacing the positioner.
Failed state requested by FF.
