Typical Applications:
The elevation (Fig. 1) and
one-line diagram (Fig. 2)
show a typical, four engine-
generator paralleling system
for automatic standby opera-
tional mode.

Load Demand … is
a load management fea-
ture that automatically
determines and keeps the
minimum required number
of generators online to
carry the actual kW load,
conserving fuel and reduc-
ing engine run time.
Bus Load
Optimization…
automatically sheds blocks
of load to prevent over-
loading of the remaining
generators, and automati-
cally re-adds individual loads
to the bus per a prescribed
sequence according to their
priority value if any genera-
tor fails.
Parallel with Utility…
can be added to the standby
and prime power PCS
automatic closed-transition
operational mode that helps
reduce energy costs by
shaving your facility’s peak
energy demand and/or ex-
port/import power to/from
the electric utility.
When Normal Source
Power Is Restored…
each ATS senses a utility
source that is within toler-
ance and, after a time delay,
individually re-transfers to
the normal position. When
the last ATS has re-trans-
