Non-Critical Status 2 - Honeywell SLG 700 Option Manual

Non-Critical Status 2

Non-Critical Status 2
Interface in BDH
Interface in BDL
Surface rate of change
exceeded
Interface rate of change
exceeded
Sensor characterization or
calibration data corrupt
Page 60 FOUNDATION Fieldbus Option User's Manual
Possible Cause
This indicates that interface
reflection has been tracked
into the upper zone near the
Reference Plane where
measurements are not
accurate.
This indicates that interface
reflection has been tracked
into the lower zone near the
End of Probe where
measurements are not
accurate.
This indicates that the rate of
change the product level is
excedding the limit
This indicates that the rate of
change the Interface level is
excedding the limit
Characterization of Sensor or
Calibration data of sensor is
corrupted.
There may be impact on the
accuracy of measurement.
Recommended Action
This is a condition that can occur
during normal operation and does not
generally require corrective action. If
this condition is triggered when it is
not expected, verify that the Blocking
Distance High parameter is set
correctly for the current conditions.
If distance to interface is in Higher
zone then status associated with
device variables derived from
distance to interface will be shown as
uncertain in local display and on host
the status would be poor accuracy.
This is a condition that can occur
during normal operation and does not
generally require corrective action. If
this condition is triggered when it is
not expected, verify that the Blocking
Distance Low parameter is set
correctly for the current conditions.
If distance to interface is in Lower
zone then status associated with
device variables derived from
distance to interface will be shown as
uncertain in local display and on host
the status would be poor accuracy.
Check the rate of change limit
parameter value is as per application
limit.
If the problem exsist check the actual
rate of change of the Level value and
if the rate is within limit then check
with Service person/support team for
details.

Restart of Device is required. If this
does not fix the problem, re-
characterization or re-calibration of
device is required to improve the
accuracy.
