next machine in the priority order and try to start it. This should be set to allow
ample time for a normal start to occur.
(4) Max Gen Stop Time (s) - This setting defines the maximum time in seconds
that generator sequencing will allow for a machine to stop. If a successful stop
does not occur within the allotted time, generator sequencing will move to the
next machine in the priority order and try to stop it. This should be set to allow
ample time for a normal stop to occur.
(5) Allow Last Unit Shutdown - Set to enable or disable to allow the last unit to shut
down if there is no load on the system.

These settings are the non-zero sequence IDs of all units that are on the inter-genset
communications network. This allows the DGC-2020s to annunciate a pre-alarm if a
machine is missing (ID Missing pre-alarm) or if an ID is repeated (ID Repeat pre-
alarm) on the network. These pre-alarms help in diagnosing problems with the inter-
genset communications network. If these pre-alarms are not desired, set all expected
sequence IDs to zero. If you want to prevent the pre-alarm for a particular machine
because it is off line, replace its sequence ID with zero in the Expected Sequence ID
settings.
Set the number corresponding to the non-zero sequence ID of each machine
participating in the inter-genset communications network. If you have N machines,
put the non-zero sequence IDs for the N units into the first N Expected Seq ID setting
positions. Additional Expected Seq ID positions should be set to zero.
It is likely that these pre-alarms will sound on multiple machines at the same time. If
the cable falls out of a unit, all the units remaining on the network should annunciate
ID Missing pre-alarms. In addition, the unit that the cable fell out of should annunciate
the pre-alarm as well, since it does not see the IDs of the other machines in its
network.
