Manual 26086 EGCP-2 Engine Generator Control Package
Woodward 57
Minimum Generator Load
• % of system load at which active master begins timing 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 Setpoint –10.
Example: Max Gen Load = 60%; Min Gen Load = 30%
With two engines operating, the Max Gen Load setpoint is viewed as 50%,
so the System Load Percentage must be 25% or less to sequence off the
next unit. This provides a buffer so that when there is a System Load
Percentage that is moving between 29 and 31%, the EGCP-2 will not
sequence the unit off and then sequence it back on.
Reduced Load Delay
• Time in seconds which 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 setpoint 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 Serial
Communications section of this manual completely before deciding on
which protocol to use. Improperly setting this item may cause a loss of
communications with the EGCP-2 on the RS-422 port.
NOTE
Changes in the 422 Protocol setpoint do not take effect until input 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 Setpoints
• Sets RS-422 Serial Communications to Upload Setpoint mode.
Modbus ID
• Sets the Modbus RTU network ID of the Unit. Units can only be Modbus
slaves.
