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.
Minimum Generator Load
 % of system load at which the Master EGCP-2 begins the Reduced Load
Delay to sequence units off line.
 With only two engines operating, the Master unit will NOT sequence off the
next unit if the System Load Percentage will increase above the Max Gen
Load –10%.
 Consult Chapter 5, Generator Sequencing, for details.
Reduced Load Delay
 Time in seconds that the active master waits before sequencing units off
line.
 Delay is effective only on active master unit.
 Lowest priority units are sequenced off line first.
Maximum Stop Time
 Time in seconds allowed by master for slave to sequence off line.
 Master begins sequencing next lowest priority unit off line if system load is
still above Min. Gen. Load set point at the end of the Max Stop Time Limit.
422 Protocol
 This setting defines the protocol used on the EGCP-2’s RS-422 port. Make
sure you are familiar with the various settings by reading the
Communication Manual 26181 completely before deciding on which protocol
to use.
Changes in the 422 Protocol set point do not take effect until power
is cycled to the control.
ServLink
 Sets RS-422 Serial Communications to ServLink Protocol
Modbus
®
 Sets RS-422 Serial Communications to Modbus RTU Protocol
Upload Set Points
 Sets RS-422 Serial Communications to Upload Set Point mode.
