Engine Driven Pumps

Also from: EDP

There are 2 EDPs mounted on the accessory gearbox on each engine. They require N3 rotation to deliver pressure. If an EDP is deprived of fluid for lubrication and cooling, the pump input shaft fails after approximately 10 minutes. This can happen, for example, when the fire pb [Pushbutton] is released.

Electrical power is required to turn off the engine driven pumps (via a solenoid).

The FAULT light on an engine driven pump pb illuminates when:

reservoir low level
reservoir overheat
reservoir low air pressure
pump low pressure (inhibited on the ground with engines off)
