Generator Break-In Procedure - Westerbeke 8.0KW - 60Hz EDT Operator's Manual

GENERATOR BREAK-IN PROCEDURE
DESCRIPTION
Although your engine has experienced a minimum of one
hour of test operations at the factory to make sure accurate
assembly procedures were followed and that the engine
operated properly, a break-in time is required. The service
life of your engine is dependent upon how the engine is
operated and serviced during its initial hours of use.
Breaki1)g-in a new engine basically involves seating the
piston rings to the cylinder walls. Excessive oil consumption
and smoky operation indicate that the cylinder walls are
glazed or scored, which is caused by overloading the
engine during the break-in period.
Your new engine requires approximately 50 hours of initial
conditioning operation
to
break in each moving part in order
to maximize the perfonnance and service life of the engine.
Perfonn this conditioning carefully, keeping in mind the
following:
Start the engine according to the STARTING PROCEDURE
section. Run the engine while checking that all systems (raw
water pump, oil pressure, battery charging) are functioning.
AFTER START-UP
Once the generator has been started, check for proper opera-
tion and then encourage a fast warm-up. Run .the generator
between 20% and 60% of full-load for the first 10 hours.
After the first 10 hours of the generator's operation, llie load
can be increased to the full-load rated output, then periodi-
cally vary the load.
Avoid overload at all times. An overload is signaled by smoky
exhaust with reduced output voltage and frequency. Monitor
the current being drawn from the generator and keep it within
the generator's rating. Since the generator operates at 1800
rpm to produce 60 hertz (or at 1500 rpm to produce 50
Hertz), control of the generator's break-in is governed by the
current drawn from the generator.
NOTE: Be aware of motor starting loads and the high current
draw required for starting motors. This starting. amperage
draw can be 3 to 5 times rionnal running amperage. 'See
GENERATOR INFORMATION in this manual.
GENERATOR ADJUSTMENTS
Once the generator has been placed into operation
(commissioned), there maybe the need to adjust the
generator:~
no-load AC voltage output. See GENERATOR
INFORMATION.
THE DAILY ROUTINE
CHECK LIST
Follow this check list each day before starting your generator.
• Check that all generator circuit breakers (power panel) are
in the off position before starting.
• Record the hourrneter reading in your log (engine hours
relate to the maintenance schedule.)
Any deficiency or problems in the following items must
be corrected before start up.
• Visually inspect the engine for fuel, oil, or water leaks.
• Check the oil level (dipstick).
• Check the coolant level in the coolant recovery tank.
• Check your fuel supply.
• Check the starting batteries (weeldy).
• Check drive belts for wear and proper tension (weeldy).
CHECK WITH THE ENGINE RUNNING.
• Check for abnonnal noise such as knocking, vibrating and
blow-back sounds.
• Confinn exhaust smoke:
When the engine is cold - White Smoke.
When the engine is warm - almost Smokeless.
When the engine is overloaded - some Black Smoke.
NOTE: Some unstable running may occur in a cold engine.
This condition should abate as normal operating temperature
is reached and loads are applied.
A
CAUTION:
Do not operate the generator for long
periods of time without a load being placed on the
generator.
STOPPING THE GENERATOR
Remove the AC loads from the generator one at a time.Allow
the generator to run for 3-5 minutes to stabilize the operating
temperatore, then tom the key to the off position. Once the
generator is shutdown, close down all circuit breakers as a
safety precaution.
CAUTION {WE~;YERLINK
Dr
NMEA~20IiO}:
The
-~ieci~nic
components in the
Digital Diesels draw a very small amount of amperage (milli-amps) from
the generator's starting battery when the unit is in a static state. This
maybe as much as 50 milli-amps for the system ECU and 50 milli-amps
jor each display. This can be as much as
72
amp~hours
in a months time
with
no generator use.
It
is not necessary to
be concerned with this slight
amperage draw during normal seasonal use. However, if
the
generator
set is not to be used for a number of months, such as winter storage, it
is
best to disconnect the DC power to the generator with a NMEA-2000
system or shut off the DC breaker on the generator's control box/or a
, WESTERLINK system.
NOTE: Keep in mind that the Westerbeke generator maybe the DC power
supply for the yessel's NMEA-2000 network.
