EGCP-2 Engine Generator Control Package Manual 26174
118 Woodward
Mains Sensing
 Over/Under Voltage
 Over/Under Frequency
 Load Surge
 Programmable for Alarm/Loss of Mains Detect
 Loss of Mains Action Timer
 Stable Mains determined by being within Voltage and Frequency Limits for a
given period of time
Synchronizing
 Phase Match Synchronization
 3 Mode Operation
 Run, Check, Permissive
 Voltage Matching
 Dead Bus Closing
 Synch Timer
 Reclose Attempt/Timer
 Manual Synchronization Capability (permissive mode)
Load Control
 Proportional Load Sharing
 Integrating Base Load and Process Control
 Load Ramping
 Remote Contact Inputs to change Base Load and Process Set Points with
Raise/Lower ramp rates
 Unload Trip point
 Droop Load Control Capability
Sequencing
 Each Unit in the system has an assigned Priority.
 Master (Highest Priority) automatically sequences units on or off line as
determined by system load.
 Higher priority units are sequenced on in order of their priority; taken off in
reverse of priority.
 System Load set point determines percent system load level at which
additional units will be brought on, or taken off line.
 Time set points determine period of delay for sequencing units on/off line.
 Separate time delay for overload (100% +) system load levels so additional
units can be sequenced on line quickly.
