Process value warning
10
Cause: Deviations from permissible ambient or process conditions detected by the device (by means of self-monitoring or
based on warnings/errors in the device) indicate that the measured value is unreliable or that deviations from the set value in
the actuators are most likely greater than anticipated under normal operating conditions.
Process or ambient conditions can damage the device or result in unreliable results.
Measure: Check ambient temperature or process conditions. If possible, install device at different location.
