Comb/Flt Hydraulic Pressure Valve Status Indications; Utility Hydraulic Pressure (Util Hyd Press); Auxiliary Hydraulic Pressure (Aux); Engine Fuel Temperature (Eng Fuel Temp) Display - Honeywell SPZ-8000 Maintenance Manual

2. E. (3) (f) COMB/FLT Hydraulic Pressure Valve Status Indications - When the
COMB/FLT HYD PRESS valves are in the closed position, amber
cross-hatching is displayed within the appropriate hydraulic
pressure digital readout window (Figure 226). When the
COMB/FLT HYD PRESS valves are in transit, amber dashes are
displayed within the appropriate hydraulic pressure digital
readout window.
(9) Utility Hydraulic pressure (UTIL HYD pRESS) - The UTIL HYD
PRESS digital readout is the left-most display in the sixth row
of the secondary engine parameter display (Figure 223). UTIL
HYD PRESS is
displayed digitally in white to a 100
PSI
resolution.
(h)
Auxiliary Hydraulic Pressure (AUX
HYD PRESS) - The AUX HYD
PRESS digital readout is located right of the UTIL HYD PRESS
display in the fifth
row of the secondary engine parameter
display (Figure 223). AUX HYD PRESS is displayed digitally in
white to a 1OO-PSI resolution.
(i)
Engine Fuel Temperature (ENG FUEL TEMP) Display - The ENG FUEL
TEMP is displayed digitally in white in the seventh row of the
secondary engine parameter display (Figure 223). The
resolution of the digital readout is 1 'C. The display digits
change color as a function of oil temperature as defined below:
RED FUEL TEMP < -40 "C
WHITE
-40 "C s FUEL TEMP <
90 "c
AMBER 90 'C s FUEL TEMP < 120 'C
RED 120 'C s FUEL TEMP
(j) Fuel Quantity (FUEL QTY) - This FUEL QTY display (Figure 223)
consists of three digital windows comprising rows 8 and 9. Two
wi;ows (row 9) corresponds to the
fuel quantity in each (L/R)
The third window (row 8) is a running total (T) of the
fuel"quantity from both tanks. All three digital displays are
white (normal) and readable to a 50-pound resolution. The
display digits go to amber when a fuel
level low indication is
received. The total window turns amber
only if both sides
indicate fuel level low.
