EGCP-2 Engine Generator Control Package Manual 26086

Main Freq Low Alm
The Main Frequency Low condition will cause a response defined by this
setpoint. The available responses are:
• Disabled
• Warning
• Loss of Mains
• Loss of Mains with Alarms
LOM Action Delay (numeric seconds)
• Sets Time Delay for LOM Action to begin once Loss of Mains is detected.
• Delay time From LOM detection to mains breaker open, and engine start
command.
• In applications where the utility bus is somewhat unstable, this setting can
be used to prevent momentary disruption of the mains frequency or voltage
on from causing unwanted Loss of Mains actions to occur.
Sequencing and Comms (Communications)
Automatic Sequencing (enabled/disabled)
• Enables or Disables Auto Sequencing for that unit.
• Can be used to disable sequencing for a particular unit in a sequencing
system if needed.
• Disabling at the master disables all auto sequencing.
Maximum Generator Load
• % system load on all units with gen breakers closed, and on the same
network, in Auto, and in Load Sharing or Process control modes, at which
active master unit will begin timing to sequence next unit on line.
Next Genset Delay
• Period of time that will pass before master auto sequences an additional
generator on line after the Maximum Generator Load Setpoint is exceeded,
and remains exceeded.
• Delay is effective only in active master unit.
Rated Load Delay
• Delay when system load exceeds 100%, before master starts next genset in
sequence.
• Overload condition fast sequence operation.
• Rated Load Delay function overrides load ramping on unit being sequenced
on line. That unit will immediately assume its proportion of the system load.
Maximum Start Time
• Time allowed by master to see next unit to be sequenced on line in an
“active” condition, i.e. started and ready to load.
• This is determined by a network flag, which indicates the unit is ready to
load, is sent over the network by the unit being sequenced on by the
master.
• If master does not detect this flag within the Max. Start Time allowed, it will
go to the next lower priority unit and try starting it, or if no other units are
available, it will retry the start command on the same unit.
