b. Observe and record the time delay on engine start. 4

c. Observe and record the cranking time(s) required to start and run for each prime mover. 5

d. Observe and record the time required to come up to operating speed for each prime 6

mover. 7

e. Record voltage and frequency overshoot. 8

f. Observe and record time required to achieve steady-state condition with all switches 9

transferred to emergency position. 10

g. Record voltage, frequency and amperes. 11

h. Start plant motor loads in sequence specified in Part 2. Record voltage and frequency 12

dip and load kW for each step. 13

i. Record oil pressure, water temperature where applicable and battery charge rate at 5-14

minute intervals for the first 15 minutes and at 15 minute intervals thereafter. 15

j. Return normal power to facility , record time delay on retransfer to normal for each 16

switch and cooldown time delay for each prime mover. 17

3. Cycle crank test: 18

a. Utilize any method recommended by manufacturer to prevent engine from running. Put 19

control switch into "run" position to cause prime mover to crank. 20

b. A complete cranking cycle shall consist of an automatic crank period of approximately 21

15 seconds duration followed by a rest period of approximately 15 seconds duration. 22

Upon starting and running of the prime mover, further cranking shall cease. Two 23

means of cranking termination shall be utilized so that one will act as a backup to the 24

other to prevent inadvertent starter engagement. Cranking limiter time shall be 75 25

seconds for cycle crank. 26

4. Record engine fuel consumption by means of test equipment. 27

5. Test all safeties specified for generator instruments and controls as recommended by 28

manufacturer and as required to verify proper operation. 29

D. Provide field service support for system commissioning, minimum 8 hours on site, in addition to 30

other field service requirements. 31

1. Coordinate with Owner’s contractor and Commissioning authority, 32

E. Replace all fluids consumed during startup and testing, including fuel. 33
