Illumination Parameter or Fault
Primary system hydraulic oil pressure is below 1250 psi.
Primary system hydraulic fluid is at minimum operating level.
A pressure differential of 60 to 80 psi has been detected in either the
pressure or return filter of the primary hydraulic system. The return
filter will bypass; the pressure filter will not.
Main transmission No. 1 system pressure is below 26-30 psi.
Main transmission No. 1 oil system temperature is above 274°- 294 °F
(135° -145 °C).
No. 1 generator is not on line.
Transformer-rectifier has failed, or there is no ac input to the rectifier.
Temperature 190 °F (87 °C) at transformer-rectifier is excessive.
Rectifier fan has probably failed.
Shaft driven compressor oil temperature is above 340°- 360 °F
(171° -182 °C); or shaft driven compressor pressurized air output is
less than 5-9 psi. No 1 engine bleed air will automatically supply the
pressurized air system if No. 1 engine is operating.
The selected multiplex bus controller has malfunctioned and the other
bus controller has assumed control of the multiplex bus. Light will
extinguish when the operating bus controller is selected with the MUX
switch on the CPG fire control panel.
Utility system hydraulic oil pressure is below 1250 psi.
Utility hydraulic fluid is at minimum operating level.
A pressure differential of 60 to 80 psid has been detected in either the
pressure or return filter of the utility hydraulic system. The return
filter will bypass; the pressure filter will not.
Main transmission No. 2 oil system pressure is below 26 - 30psi.
Main transmission No. 2 oil system temperature is above 274°- 294 °F
(135° -145 °C).
No. 2 generator is not on line.
Transformer-rectifier has failed, or there is no ac input to the rectifier,
Temperature 190 °F (87 °C) at transformer-rectifier is excessive.
Rectifier fan has probably failed.
Canopy doors are not properly closed.
