Each generator section shall provide paralleling for two (2) engine-generator sets. Each
engine-generator set shall be rated at ____ amperes, [3 | 4] pole.
B. Generator Control System
Each generator section shall include two (2) ASCO integrated controllers for
synchronization, load sharing and transfer switch control. Applications shall allow up to
four (4) engine-generator sets to be precisely controlled and paralleled. Controls shall
provide soft bump-less loading and unloading of generators from the main bus. The
ASCO integrated controller shall additionally provide multiple circuit interlock for first-
up, first-on operation of the engine-generator set. This device shall positively prevent
more than one set from being simultaneously connected to a dead bus. Upon initiation of
the connection of the first set to the bus, this circuit shall shift the control of the
remaining sets to automatic synchronizing.
C. Emergency Stops
The system shall include a master E-Stop push button and individual E-Stop push
buttons for each engine-generator.
D. Mode Selector Switch
A three-position mode selector switch shall provide the following:
System Off. Normal shut down of an operating system.
System in Auto. Start/stop of all available generators by a single customer
contact.
System On. Constantly runs all available generators.
E. Power Management Selector Switch (optional)
Power Management Selector Switch shall enable/disable power management
applications if option is included. Power Management Applications include:
Generator Load Demand. Add or remove generators from the bus based on the
spinning reserve capacity of the power system (head room).
Load Bus Optimization. Add or shed loads based on load KW and spinning
reserve capacity of the power system (head room).
Gen Start on Alarm. If a genset issues a warning alarm, this feature will start the
next priority generator, add it to the bus, and remove the alarming genset.
