Preset, before repeating on that List, it will first re-attempt at the Last Commanded and Last
Successful carrier settings. This cycle will continue indefinitely until success, or an authorized
user changes the carrier setting. If a unit does eventually acquire and remain on a new carrier
setting because of an Auto Recovery, the local user is, if local control is enabled, authorized to
abort the newly-acquired carrier and force a re-attempt at the original authorized carrier settings.

Note that a unit may also be forced into Auto Recovery when encountering a Compel
network command that bears a Header which does not match the internal Header setting, and
whose security does not allow “Sharing”. See Section 3.1.1 for more details.

Once the unit enters Auto Recovery, then another timer, called “Local Control Re-enable”
may begin counting down. This timer can only be aborted if Auto Recovery is vacated. If this
timer expires while the unit is still in active Auto Recovery, the unit will automatically clear the
“Local Control Disabled” flag, so that local users now have full local control. This will allow
networks, in the ultimate disaster scenario where all backup carrier settings are unusable, to use
local personnel to re-program the units to new settings.

Entry into Auto Recovery will show both as an indication to the user on the Front-panel, and
it will be logged to the Ops Log. If recovery is made to a new carrier setting, that will continue
to be a maskable fault condition, a Warning.

The user controls affecting Auto Recovery Modes are listed below. The primary method
for setting these values will be Compel or the factory:

Fault Indications
The iPump6420 interprets fault conditions as either 1) failures in i6420 operation, 2)
problems detected in incoming signals, or 3) inability to honor command requests. Typically,
fault conditions may be allowed to show as an Alarm, a Warning, or not to indicate at all.
Control of this is set by a programmable fault indication mask, usually set at the factory.

Control of this is set by a programmable fault indication mask, usually set at the factory.
Fault conditions allowed by the mask to indicate as Alarms will 1) de-energize the rear-
panel Alarm contacts, 2) show on the front-panel ALARM LED, 3) show in local web screens,
and 4) show on Compel Return Path Status reports. Similarly, Warning indications will show in
the same manner, though there is no rear-panel closure.
and 4) show on Compel Return Path Status reports. Similarly, Warning indications will show in
the same manner, though there is no rear-panel closure.
The Fault Indications will usually show for the length of time that the fault exists. In some
cases, the fault indication is transitory. In these cases, the indication may be lengthened to
several seconds or a few minutes, to allow user recognition and monitoring. In other cases, the
indication may last until there is a successful instance of the same operation that had previously
faulted (or the unit reboots).

Appendix 3 gives a complete list of all the Fault conditions.
