3.3.2
Functional Acceptance Tests
Functional Acceptance Tests shall[ be coordinated with Section 16237N
SINGLE OPERATION GENERATOR SETS and shall] include simulating power failure
and demonstrating the following operations for each automatic transfer
switch. Contractor shall show by demonstration in service that the
automatic transfer switches are in good operating condition, and function
not less than five times.
a.
Perform automatic transfer tests:
1.
Simulate loss of normal/preferred power.
2.
Return to normal/preferred power.
3.
Simulate loss of emergency power.
4.
Simulate all forms of single-phase conditions.
b.
Verify correct operation and timing of the following functions:
1.
Normal source voltage-sensing relays.
2.
Engine start sequence.
3.
Time delay upon transfer.
4.
Alternate source voltage-sensing relays.
5.
Automatic transfer operation.
6.
Interlocks and limit switch function.
7.
Time delay and retransfer upon normal power restoration.
