engine-generator set is operating. Do not provide
duplex filters when the engine-generator set is to
be installed in an enclosure or provided with an
engine-driven radiator.
**************************************************************************
Provide each engine with the manufacturer's standard fuel system integral
with the engine, complete with necessary piping, fittings, and valves for
connecting items of equipment which are a part of the system. Provide
engine manufacturer's standard hand priming pump. Provide manufacturer's
standard[ simplex][ duplex] filter for each engine, of the throwaway filter
element type, consisting of shell filter elements, drains, and necessary
connections and fittings. [Arrange duplex filter such that flow may be
diverted from one chamber to the other without interruption at any point of
the changeover.]
2.1.2.9
Engine Intake Filter
Provide intake filter assemblies for each engine of the oil bath or dry
type, as standard with the manufacturer. Filters shall be capable of
removing a minimum of 92 percent of dirt and abrasive 3 microns and larger
from intake air. Size filters to suit engine requirements at 100 percent
of rated full load. Design unit for field access for maintenance purposes.
2.1.2.10
Engine Starting System
Starting shall be accomplished using an adequately sized dc starter system
with a positive shift solenoid to engage the starter motor and to crank the
engine continuously for 60 seconds without overheating.
2.1.2.11
Jacket Coolant Heating System
Provide a factory-installed,[ 120][ _____] volts ac, jacket coolant heating
system to ensure rapid starting. Thermostatically control heater at the
temperature recommended by engine manufacturer. Include necessary
equipment, piping, controls, wiring, and accessories.
2.1.2.12
Engine Protective (Shutdown) Devices
Equip each engine with devices to shut down the engine by shutting off the
fuel supply to the engine via a fuel shutoff solenoid. Auxiliary contacts
shall be suitable for activating a remote alarm system. Shutdown shall
open the associated generator circuit breaker. Provide the following
shutdown devices:
a.
Overspeed device which operates when engine speed exceeds normal
synchronous speed by 18 percent or as recommended by manufacturer.
Device shall require manual reset.
b.
Pressure switch which operates when lubricating oil pressure to engine
drops below a preset value.
c.
Temperature switch which operates when jacket coolant temperature
exceeds a preset value.
d.
Device which operates when the coolant level in the radiator drops
below a preset level.
e.
Other shutdown devices as recommended by the engine manufacturer.
