Unit Numbers 2 through 505
The selected inverter has failed. 

550 and on:
AC Bus Failure,
One or both inverters have failed.  

Triggers MASTER WARNING index

 

 

 

 

 

 

 

 

 

 

 

 

 

Steady Illumination: Battery temp has reached 145 degrees F.
Flashing indicated the battery has reached a temperature of 165 degrees F.

Triggers MASTER WARNING index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cabin pressure is above 10,000 Feet

Triggers MASTER WARNING index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Oil pressure is below 35 PSI in the left or right engine.

Triggers MASTER WARNING index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Fuel quantity according to the float switch is between
169 and 219 pounds useable in the indicated tank. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Fuel pressure is low. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Left or right hydraulic pump output is below normal.
Unit numbers 2 through 436 indicate "L/R HYD PRESS LOW". index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Either of the following:
1.  Throttle is below the 60% N2 position
2.  Nacelle Inlet Temp is below 104 degrees C
3.  Engine Stator Anti-Ice Vale is not fully open
4.  Failure of automatic temperature controller (light modulates on and off)
5.  Failure of wing leading edge to stay within range (one or more heating elements inop.)
6.  Wing leading edge temperature below 16 degrees C index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Indicates proper boot inflation pressure.
 Illuminates twice during the 12 second cycle. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Generator power relay is open.
 Illumination of both LH and RH triggers the MASTER WARNING. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Either the #1 or the #2 inverter has failed.
Illumination of either LH or RH lights triggers the AC Fail
Annunciator, which in turn triggers the MASTER WARNING. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Emergency pressurization has been manually selected, or the ACM has overheated.
During ACM overheat, if the ACM cools down with 12 seconds, it will revert to normal
operation. During overheat on the Ground, the emergency pressurization valve does
not open (de-activated by squat switch) but the light illuminates. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Pressurization source selector is in the GNP position and the Ground Valve is open. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Brake hydraulic pressure is low. Anti Skid Inop will also illuminate. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Filter bypassing of the indicated filter is impending or occurring. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

With fuel boost pump switch in the NORM position, this illuminates with the Annunciator.
FUEL BOOST ON also illuminates with the switch in the ON Position. Automatically illuminates with the switch in the
normal position during engine start, and crossfeeding. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Fluid level is below .2 gallons. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

System is pressurized. On when T/R's are deployed, and when gear or speed brakes are cycling. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Pitot static heater is off, or with the switch on, power has been disconnected from the pitot tube heater,
or one or both static port heaters. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Left and right speed brakes are fully extended. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Temp in the duct from the ACM to the cabin is excessively high temperature. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Unit numbers 482, 485 and on... The ground valve has closed because
the secondary overpressure switch has activated. Normal DC power must be removed
to reset. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Control switch is off, the unit is is test mode, or the Anti Skid Unit is inoperative.
This Annunciator is off with the gear handle in the UP position. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Indicates that either nose baggage door tailcone compartment door, or 
main cabin door is not locked. index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The fuel and hydraulic shutoff valves are fully closed. They can be re-opened by
pressing the ENG FIRE switch a second time.  index

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1-  With the control switch in either position, bleed air to the windshield
exceeds 146 degrees C.  2- With the control switch off it indicates that the shutoff valve
has failed open, or is leaking bleed air, allowing line pressure to exceed 5 psi. index
