 The reservoir filling selector gets the signals from all three of the synchros. When it is set to one of the three systems, the signal from the applicable synchro is sent to the reservoir quantity indicator. The applicable system indicator light comes on and the contents of that reservoir are shown on the reservoir quantity indicator.
 If the quantity of hydraulic fluid is below a specified minimum, the float of the low level switch operates the switch. Discrete signals are sent to the SDAC and to the overhead panel. The SDAC makes these warnings come on:
 -a low level warning on the engine/warning display,
 -the MASTER CAUT attention getter,
 -a single-chime audio warning.
 The signal to the overhead panel makes the applicable FAULT annunciator(s) come on.
 If the low level switch does not operate, the SDAC uses the data from the contents transmitter to start low level warning procedure. The warning is generated when the transmitter data show that the contents are below the low level switch threshold. The SDAC makes the warnings occur when the content of the reservoirs are 2.5 l (0.6604 USgal) (Green And Yellow reservoirs) or
 1.8 l (0.4755 USgal) (Blue reservoir). In this case, there will be no FAULT indication on the overhead panel.
