Cause: Deviations from permissible ambient or process conditions detected by the device (by means of self-monitoring or
based on errors in the device) indicate that the measured value is unreliable or deviations from the set value in the actuators
is most likely greater than anticipated under normal operating conditions.
Process or ambient conditions will damage the device or result in unreliable output.
Measure: Check ambient temperature or process conditions. If possible, install device at different location.
