to determine the appropriate corrective action. Refer to
Possible causes
ADB Block is not licensed. The
algorithm status will indicate
"Not Licensed."
Resource Block actual mode is
OOS
ADB Block actual mode is OOS
Algorithms were not activated
or configured properly
(SPM algorithm only) variable
to be monitored is in
unscheduled function block
(SPM only) block in which
process variable is coming
from is not in Auto mode
Not enough process noise or
there is no flow in the line
Process dynamics are unstable
Learning period is too short
(PIL only) PIL Learning
Sensitivity not properly
configured
Problem in Sensor Transducer

Possible causes
Some LCD display segments have gone
bad
Device exceeds temperature limit for
the LCD display. (-20 to 80 °C)
for complete information.
Recommended action
1. Check DIAG_OPTIONS in the Resource Block. PIL/SPM or
a hex value of 0x00000300 should be shown. See
"Advanced Diagnostics Transducer Block (ADB)" on page 213
1. Determine why Resource Block is in OOS.
2. Correct problem then put Resource Block in Auto mode.
1. Put ADB block into Auto mode.
1. To activate and configure SPM see
operation" on page 73
2. To activate and configure PIL, see
technology" on page 84
1. Download a schedule into the function block.
2. Consult host documentation for downloading
schedules.
1. Put monitored block into Auto mode.
1. Check to see if the process is flowing.
2. Your process may have low process dynamics. You can
turn off this check. This should only be done after
considering the possible results, see
detection" on page 91
1. Ensure the process flow is stable.
1. Ensure the SPM Monitoring Cycle or PIL Learning Length
is at least as long as any dominant cycling or oscillation
in the process. See
.
page 73
The process may be varying by more than algorithm is
configured for. Adjust learning sensitivity to compensate,

Recommended action
See XXXX (Self Test). If some
of the segment is bad, replace
the LCD display.
Check ambient temperature
of the device.
