Verifying that the automatic load sequence timer is OPERABLE with the interval between each load block within i 10% of its design interval.

b.

At least once per 92 days by verifying that a sample of diesel fuel

~

from the fuel storage tank is within the acceptable limits specified in Table 1 of ASTM D975-81 when checked for viscosity, watersand l

sediment.

At least once per 184 days by verifying the diesel starts from ambient c.

condition and accelerates to at least 900 rpm in < 10 seconds.

All engine starts for the purpose of this Surveilla1ce Requir'efnent may

. be preceded by an engine prelube period and/or other warmup procedures recommended by the manufacturer so that mechanical wear and stress on the diesel engine is minimized.
