(Electronics)
(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
wiring board (PWB)
assembly. Replace the
PWB assembly.
Static Memory
(Enabled) A failure of the FRAM memory
where static parameters are
stored.
Processor
(Enabled) A failure of the main
Processor.
I/O Processor
(Enabled) A failure of the I/O Processor.
Output Block Timeout

(Maintenance Output Block
Timeout
(Disabled) If the AO or DO block has not
executed for longer than the
configured timeout, this alert is
detected. 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. Check Output
Block The function block
providing the setpoint
for the valve position
(AO or DO function
block) has not
executed within the
user configured time
limit. If configured for
Self Test Shutdown,
the transducer Actual
mode is set to Out of
Service.
1) Download the
control schedule from
the host configuration
device.
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
Service.
To correct this
situation, download the
configuration to the
device and set the
Target Mode of the
Resource block.
