(Maintenance) Program Memory
(Enabled) A pending Flash or NVM
failure is present. If configured for Self Test
Shutdown, then the
transducer Actual mode is
placed Out of Service until the
problem is fixed. Out of
Service results in the
instrument output pressure(s)
and actuator position being at
the Zero Power Condition. Replace PWB
assembly An error has been
detected in the printed

executed for longer than the
configured timeout, this alert is
detected. If configured for Self Test

2) Make sure the Time
Out Alert Point is
greater than the block
execution schedule.
This alert should only
be utilized in very
critical loops where
execution time is
critical.
Blocks Set to Default
(Configuration)
(Failed) Blocks Set to
Default
(Enabled) If the resource block has
undergone Restart with
Defaults. The transducer “Actual” mode
is placed Out of Service when
the defaults are applied. Out
of service results in the
actuator being at the Zero
Power Condition. Download device
configuration When restoring power
to the device, the
configuration
parameters could not
be recalled from
non-volatile memory.
When the instrument
detects this condition,
the transducer Actual
mode is set to Out of
