6.8.6 External Additive Stream Alarms
Alarm
Cause
Batch additive vol
-
ume deviation
Batch 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.
Injector command
rejected
When external additive controller does not recognize the
command sent by MSC-L or is not in correct state to
execute the command, it rejects the command with an error
code resulting in injector command rejected alarm on the
MSC-L.
Device offline
The device offline alarm occurs if the external additive does
not respond to any commands sent for that stream for the
configured timeout. This alarm will not be generated if the
external additive is not associated with any of the arms.
Leaking Valve [*]
when the
[leaking timeout period]
is more than the
[leaking
volume limit]
measured at the pulse input of that particular
stream. It is also generated in between injections (during a
transaction) if the
[leaking volume limit]
is measured inside
the
[leaking timeout period]
.
Flush Volume [*]
This alarm is generated when the wild stream between
entering the slow flow state and closing the transaction is
less than the configured
[Flush Volume]
-
[Flush Volume
deviation]
. The
[Flush Volume deviation]
is entered as the
percentage of the
[Flush Volume]
.
No Activity [*]
This alarm is generated when Inject now command is not
received in the
[No activity timeout]
, either after enabling
permissive command or after a previous inject now
command.
No Additive [*]
This alarm is generated when the
[number of retries]
*
[no
additive timeout]
is elapsed and during an injection process
when the additive pulses stop. As soon as the additive
solenoid opens, the timer
[no additive timeout]
starts.
No Pump [*]
This alarm is generated when the pump does not receive a
feedback signal within the
[pump feedback timeout]
. It is
only possible if the I/O binding for the pump is ON/OFF and
the pump indications are configured.
Add Volume Devia
-
tion [*]
Injection volume calculated over configured number of
cycles exceeds the additive deviation percentage.
Control Fault [*]
This alarm is generated when the MSC-A is not configured
appropriately and does not have sufficient time to handle all
the inject triggers.
Solenoid Fault [*]
This alarm is generated when the system cannot activate or
deactivate the solenoid.
