5.11.4.3.2 External Additive Alarms Generated by MSC-L
5.11.4.3.2.1 Device offline alarm
The device offline alarm occurs if the external additive controller does
not respond to any commands sent for that stream for the configured
timeout. When this alarm is cleared, a disable permissive command is
sent to the external additive controller if the alarm action is configured to
Display shutdown. If Permissive command repetition is disabled in
external additive controller, then it can generate Injector command
rejected alarm while clearing the device offline alarm if there is no
transaction in progress for that stream on the external additive
controller. This alarm can be cleared.
The device offline alarm will also be raised when communication can be
established with external additive within given time. This alarm will not
be generated if the external additive is not associated with any of the
arms.
5.11.4.3.2.2 Injector command rejected alarm
When external additive controller does not recognize the command sent
by MSC-L or it is not in correct state to execute the command, it rejects
the command with an error code resulting in injector command rejected
alarm on MSC-L. For more information on Error Code, refer chapter
“FMC Smith Protocol” in “Fusion 4 Communication Manual”.
Example: If disable injector command is sent when no transaction is in
progress, the external additive controller rejects the command. The
error code for the command rejection can be viewed in alarm log.
5.11.4.3.2.3 Batch additive deviation alarm
Batch additive deviation alarm is generated only at the end of the batch.
The alarm is generated if there is a deviation of more than half of
injection volume between the actual additive quantity delivered and the
expected additive quantity to be delivered for the entire batch.
5.11.4.3.3 Mapping of Alarms on External Additive Controller
Refer to the table below for alarm mapping between alarms on the
MSC-A to alarms that appear on the MSC-L device for external additive
streams. Alarms on other external additive controllers shall have their
own mapping to alarm bit masks.
