1. A diagnostic control assembly comprising:
one or more sensors positioned to generate one or more sensor signals indicative of operating parameters associated with one or more hydraulic fracturing units; and
a supervisory control unit configured to:
receive a fluid level signal from the one or more sensors, the fluid level signal indicative of a level of fluid in a fluid reservoir of an auxiliary system, and the auxiliary system being one or more of lubrication equipment, cooling equipment, or hydraulic equipment of at least one of the one or more hydraulic fracturing units; and
when the fluid level signal is indicative of a fluid level below a minimum fluid level, generate a low level signal indicative of the fluid level below the minimum fluid level.
