•Restart Actions (RESTART [16])
WARNING
Restarting the instrument may cause loss of process control. To avoid personal injury and property damage caused by the
release of pressure of process fluid, isolate the valve from the process and equalize pressure on both sides of the valve or
bleed off the process fluid.
You can restart the instrument to reset parameters, links, etc. within the instrument. However, due to the effect that a
restart can have on the instrument, and therefore the control loop, restarting the instrument should be used
cautiously and only as a last measure. The following procedure describes how to use Restart Options to restart the
instrument with a Field Communicator. You can also restart the instrument using ValveLink software or from a host
system using the Restart method included with the device description (DD) software.
You can restart the instrument any time it is connected to an active segment.
1. Restart informs you about what can happen when an instrument restart is performed. Select Yes to continue, or No
to abort without restarting.
2. Select the desired restart action or select EXIT to exit Restart. Select Help (not the Help button) to get information
on restart actions.
There are two different restarts: Restart Processor, and Restart with Defaults:
When selecting either of these options, Restart informs you of the consequences of this action and asks if you want to
continue. Select Yes to perform the restart action, select No to select another action or exit. Restart informs you when
the restart is completed. You must acknowledge the message to continue.
Restart Processor—Performing a Restart Processor has the same effect as removing power from the instrument and
re‐applying power. Configuration and calibration do not change.
Restart with Defaults—Performing a Restart with Defaults should be done with care. This restart resets most of the
static and non‐volatile parameters for all of the blocks in the instrument to their initial value, as listed in table 4‐1. After
a Restart with Defaults, you should place the instrument in service (the transducer block mode to auto) and run Device
Setup and download the instrument configuration from the control system to properly setup the instrument. You also
may need to re‐establish communication links and trends.
•Fault State(FAULT_STATE [28]), when active, indicates that the resource block is currently forcing the output block
to perform its FSTATE action. Selecting Fault State enables the ability to manually set and clear the fault state.
•Set Fault State (SET_FSTATE [29]), when selected, changes the Fault State (FAULT_STATE [28]) to Active. Setting Set
FState (SET_FSTATE [29]) to SET manually places the instrument in the fault state.
•Clear Fault State (CLR_FSTATE [30]), when set to CLEAR clears the device fault state, if no faults are currently active.
You can test the actions the output blocks will perform by manually setting fault state active.
