engineer that the test results fall within the manufacturer's recommended
limits and meet the specified requirements performance. The report shall
be dated and signed by the start-up engineer, and submitted for approval by
the Contracting Officer. The Contracting Officer[ and LANTNAVFACENGCOM
CI52 (757-322-8420)] will witness final acceptance tests. Testing shall
include but not be limited to:
a.
Verify proper functioning of each engine protective shutdown device and
pre-shutdown alarm device. Testing of the devices shall be
accomplished by simulating device actuation and observing proper alarm
and engine shutdown operation.
b.
Verify proper functioning of the engine overspeed trip device.
Testing of the overspeed trip device shall be accomplished by raising
the speed of the engine-generator set until an overspeed trip is
experienced.
c.
Verify proper functioning of the crank cycle/terminate relay.
Testing
of the relay shall be accomplished by engaging the starter motor with
the engine being prevented from running. Observe the complete
crank/rest cycle as described in the paragraph entitled "Crank
Cycle/Terminate Relay."
d.
Verify proper functioning of the following automatic and manual
operations. Testing shall include but not be limited to:
1.
Loss of Utility: Initiate a normal power failure with connected
test load of rated kW at 1.0 power factor. Record time delay on
start, cranking time until engine starts and runs, time to come up
to operating speed, voltage and frequency overshoot, and time to
achieve steady state conditions with all switches transferred to
emergency position.
2.
Return of Utility: Return normal power and record time delay on
retransfer for each automatic transfer switch, and time delay on
engine cooldown and shutdown.
3.
Manual starting
4.
Emergency stop
e.
Operate the engine-generator set at rated current (amperes) until the
jacket water temperature stabilizes. Stabilization will be considered
to have occurred when three consecutive temperature readings remain
unchanged. Continue to operate the generator set for an additional 2
hours. Record instrument readings for terminal voltage, line current,
frequency (Hz), engine speed rpm, lubricating oil pressure, jacket
water temperature, and ambient temperature at 5 minute intervals for
first 15 minutes and at 15 minute intervals thereafter.
