TESTING POLICY:
Before any generator is shipped from the factory, it is fully
checked for performance. The generator is loaded to its full
capacity, and the voltage, current, and frequency are carefully
checked.
Rated output of generators is based on engineering tests of
typical units, and is subject to, and limited by, the temperature,
altitude, fuel, and other conditions specified by the manufacturer
of the applicable engines.
INTRODUCTION AND
DESCRIPTION
The package standby engine generator set includes all items
necessary for a completely automatic standby power system as
standard equipment. The entire package is then tested to insure
proper operation of all components and the total system perform-
ance and reliability.
DESCRIPTION
This package power system is designed to automatically provide
standby power to unattended loads during electrical outages.
Upon an interruption of normal electrical service this package
power system's electrical control circuits will automatically start
the engine. The generator will produce electrical power and the
Automatic Transfer Switch (A.T.S.) will automatically transfer the
electrical loads to the engine-generator set. Upon restoration of
normal electrical service the A.T.S. will sense return of the normal
commercial power and retransfer the load back to normal
commercial power source. The engine control circuits shut off the
run signal to the engine generator set.
These package power systems consist of two major components:
1) AUTOMATIC TRANSFER SWITCH (UL LISTED)
The Automatic Transfer Switches (A.T.S.) is a wall mount switch
designed for inside installation. A electronic exerciser circuit is
installed in the A.T.S. as standard equipment. The A.T.S. also
contains the power failure sensing circuitry necessary to send a
start/stop signal to the engine generator set. The following is a list
of recommended A.T.S. sizes for each model. Outside switches
as well as additional sizes are available, consult your sales rep
for additional information.

2) ENGINE/GENERATOR
PSS50LS- The engine generator set consists of a GM 5.7L, V-8
industrial, liquid cooled engine equipped to run on L.P./N.G. fuel.
The engine operates at 1800 rpm and frequency regulation is
maintained by the electronic governor within .5 cycles variation,
from no load to rated load. The 50,000 watt (50kW) generator is
a single bearing, direct drive, rotating field design. The generator
is connected to the engine flywheel via flexible drive disks. The
engine generator is mounted in a weather proof enclosure for
outside installation. Connection boxes are provided to all
customer connections (both AC output and DC control). A
customer supplied 12 Volt, 650 CCA (BCI group 24) battery is
required to complete the installation. Engine operation is con-
trolled by a Digital Genset Controller (DGC) mounted in the
engine generator enclosure.

Turbo charged V-8 industrial, liquid cooled engine equipped to
run on L.P./N.G. fuel. The engine operates at 1800 rpm and
frequency regulation is maintained by the engine governor within
.5 cycles variation, no load to rated load. The 75,000 watt (75kW)
generator is a single bearing, direct drive, rotating field design.
The generator is connected to the engine flywheel via flexible
drive disks. The engine generator is mounted in a weather proof
enclosure for outside installation. Connection boxes are provided

** NOTICE **
These units will automatically transfer if a power outage occurs
while running in an exercise mode.
ENGINE CONTROL MODULE (DGC-2020)
The DGC-2020 Digital Genset Controller provides integrated
engine-genset control, protection, and metering in a single
package. Microprocessor based technology allows for exact
measurement, set point adjustment, and timing functions. Front
panel controls and indicators enable quick and simple DGC-2020
operation. Basler Electric communication software
(BESTCOMSPlus) allows units to be easily customized for each
application. A wide temperature-range liquid crystal display (LCD)
with backlighting can be viewed under a wide range of ambient
light and temperature conditions.
FEATURES
DGC-2020 Digital Genset Controllers have the following features:
• Local and Remote Generator Control
• Engine and Generator Protection
• Programmable Analog Engine Senders
• Programmable Logic
• Automatic Transfer Switch Control (Mains Failure)
• Integrated RS485
• Auto Synchronizing
FUNCTIONS
DGC-2020 Digital Genset Controllers perform the following
