Rated Load Delay

 • Delay when system load exceeds 100%, before master starts next genset in sequence. 

• Rated Load Delay function overrides load ramping on unit being sequenced on line. That unit will immediately assume its proportion of the system load.

• 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.

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.
