LIMITING CONDITIONS FOR OPERATION SURVEILLANCE REQL'IREMENTS 3.9.A 4.9.A (cont'd.)

During the monthly generator test the diesel generator starting air compressor shall be checked for operation and its ability te recharge air receivers.

The operation of the diesel fuel oil transfer pumps'and fuel oil day tank level switches shall be demonstrated, and the diesel starting time to reach rated voltage and frequency shall be logged.

Note 1: Failure to synchronice within 30 seconds will not be construed as a failure, but that particular test will be repeated.

Note 2: Factory tests, which duplicates the conditions of this test, will be included in the total number.

b. Once per operating cycle the condition under which the diesel generator is required will be siculated and a test conducted to demonstrate that it will start and accept the emergency load within :he specified time sequence.

The results shall be logged.

l c. Once a month the quantity of diesel fuel available shall be logged.

d. Every three conths and upon delivery a sa=ple of diesel fuel shall be checked for quality. The quality shall be within the acceptable Ifmits specified in Table 1 of ASTM D975-68 for Nos. 1D or 2D and logged.

e. Each diesel generator shall be given an annual inspection in accordance with instructions based on the manufacturer's recor endations.
