1. Schematic Lines - green/white
Schematic lines representing hydraulic systems and pressure transfer lines are
green when pressurized and white when unpressurized.
2. System Pressure Readout (3) - white/amber
Hydraulic system pressure (psi) is shown digitally at the head of each system.
White digits turn amber and are boxed when the pressure is out of limits (high
or low). When no valid pressure data is available, the digits are replaced by
an amber "X".
3. Reversible Motor Pumps (2) - white/green/amber
RMPs are displayed as double valve symbols. When closed, the valves are
white with valve lines perpendicular to the schematic line. When open, these
valves are green and the valve lines are parallel to the schematic line. If the
valves do not go to the commanded position within 8 seconds, the
commanded valve position is displayed in amber with DISAG in amber above
the valves.
4. Reservoir Temperature Readout (3) - white/amber
Reservoir temperature in degrees C is shown in white digits to the right of
each reservoir. If the temperature exceeds 100 degrees C, the digits are
displayed in amber and are boxed. The digits are replaced by an amber "X"
when no valid temperature is available.
