c.
Activate the manual emergency stop switch and verify that the
engine stops.
d.
elements from the engine and temporarily install a temperature
gauge in their normal locations on the engine (required for
safety, not for recorded data). Where necessary provide temporary
wiring harness to connect the sensing elements to their permanent
electrical leads.
e.
Start the engine, record the starting time, make and record engine
manufacturer's after-starting checks and inspections during a
reasonable warm-up period. Operate the engine-generator set at no
load until the output voltage and frequency stabilize. Monitor
the temporarily installed temperature gauges. If either
temperature reading exceeds the value required for an alarm
condition, activate the manual emergency stop switch.
f.
Immerse the elements in a vessel containing controlled-temperature
hot oil and record the temperature at which the pre-high alarm
activates and the temperature at which the engine shuts down.
Remove the temporary temperature gauges and reinstall the
temperature sensors on the engine.
g.
Remove the high and pre-high coolant temperature sensing elements
from the engine and temporarily install a temperature gauge in
their normal locations on the engine (required for safety, not for
recorded data). Where necessary provide temporary wiring harness
to connect the sensing elements to their permanent electrical
leads.
h.
Start the engine, record the starting time, make and record engine
manufacturer's after-starting checks and inspections during a
reasonable warm-up period. Operate the engine generator-set at no
load until the output voltage and frequency stabilize.
i.
Immerse the elements in a vessel containing controlled-temperature
hot oil and record the temperature at which the pre-high alarm
activates and the temperature at which the engine shuts down.
Remove the temporary temperature gauges and reinstall the
temperature sensors on the engine.
j.
Start the engine, record the starting time, make and record engine
manufacturer's after-starting checks and inspections during a
reasonable warm-up period.
k.
Operate the engine generator-set for at least 2 hours at 75% of
Service Load.
l.
Verify proper operation and setpoints of gauges and instruments.
m.
Verify proper operation of ancillary equipment.
n.
Manually adjust the governor to increase engine speed past the
overspeed limit. Record the RPM at which the engine shuts down.
o.
Start the engine, record the starting time, make and record engine
manufacturer's after-starting checks and inspections and operate
