(4) Delayed Start Level 2 (PU) - This setting defines the level (in Per Unit) at
which the sequence for starting another machine should occur. Once the
Start Level 2 Timeout has expired, another machine will be started.
(5) Start Level 2 Timeout - This setting defines the desired delay before starting
a machine when the system per unit power level has exceeded Delayed Start
Level 2.
(6) Delayed Stop Level (PU) - This setting defines the level (in Per Unit) at which
the sequence for stopping another machine should occur. Once the Stop
Level Timeout has expired, another machine will be shut down.
(7) Stop Level Timeout - This setting defines the desired delay before stopping a
machine when the system per unit power level has been less than Delayed
Stop Level.

Set up the individual parameters according to:
(1) Mode - Select the desired generator-sequencing mode. Selections include
Disabled, Staggered Service Time, Balanced Service Time, Largest Size First,
Smallest Size First, Smallest Unit ID First, and Adopt System Mode.
When Disabled, the unit does not participate in sequencing. When any mode
other than Disabled or Adopt System Mode is selected, all machines on the
inter-genset communications network will switch to the newly programmed
mode. If generator sequencing is being set up before an inter-genset
communications network is in place, the same mode should be set for all
machines. If a machine is added to the inter-genset communications network
and Adopt System Mode is selected, the machine’s sequencing mode will
switch to the mode of the rest of the machines on the network.
(2) Sequence ID - Enter a number for sequence ID. The ID must be a unique non-
zero number for each machine that is to participate in generator sequencing.
Any machines with zero for a sequence ID will not participate in generator
sequencing. In addition, machines with zero for a sequence ID will not be
considered when network status is checked for the ID Missing and ID Repeat
pre-alarms. These are discussed in detail in the paragraphs titled Configure the
Generator Network parameters below.
(3) Max Gen Start Time (s) - This setting defines the maximum time in seconds
that generator sequencing will allow for a machine to start. If a successful start
does not occur within the allotted time, generator sequencing will move to the
