valves. Each valve has a manual override lever.
The pressure filter module is non-bypass type with a 5-15
micron, non-cleanable, cartridge type filter element.
The pressure filter module has these components:
* Filter head in the standby hydraulic system module
* Filter bowl
* Replaceable filter element.
The case drain filter module is non-bypass type with a 10-20
micron, non-cleanable, cartridge type filter element.
The case drain filter module has these components:
* Filter module head
* Filter bowl
* Replaceable filter element.
The EMDP low pressure switch is a sealed assembly with a
piston, disc spring and electrical switch.
Functional Description
Hydraulic pressure from the EMDP goes through the pressure
filter to the standby rudder shutoff valve and the leading edge
flaps and slats shutoff valve.

The EMDP pump low pressure switch sends signals to the
STANDBY HYD LOW PRESSURE light on the flight control panel
in the flight compartment when the pressure is less than
normal.
See the hydraulic indicating system section for more
information about hydraulic pump low pressure warning
indication. (SECTION 29-30)
The standby rudder shutoff valve operates electrically to control
standby pressure to the standby rudder power control unit. A
lever on the valve shows the valve position. You use the lever to
move the valve to the open or closed position.
The leading edge flaps and slats shutoff valve operates
electrically to control standby pressure to the leading edge
flaps and slats. The valve opens during alternate operation of
the leading edge flaps and slats. A lever on the valve shows the
valve position. You use the lever to move the valve to the open
or closed position.
The pressure relief valve prevents high pressure in the standby
hydraulic system. The valve opens at 3500 psi and vents the
pressure to the return line. The valve closes at 3400 psi.
The case drain filter module cleans the case drain fluid from the
EMDP before it goes back to the reservoir.
Training Information Point
CAUTION: MAKE SURE UNWANTED MATERIAL DOES NOT
GO INTO THE MODULE PORTS OR THE
HYDRAULIC LINES DURING THE INSTALLATION.
THIS CAN CAUSE DAMAGE TO THE EQUIPMENT.
You can replace each component on the standby hydraulic
system module.
Filter Element Replacement
CAUTION: PUT HYDRAULIC FLUID IN THE FILTER BOWL
BEFORE YOU PUT THE FILTER ELEMENT IN THE
FILTER BOWL. AIR BELOW THE FILTER ELEMENT
CAN CAUSE DAMAGE TO IT.
NOTE: You can not clean the pressure and case drain filter
elements and use them again.
If you replace the pressure filter element, you must do the
pressure filter element installation test.
If you replace the case drain filter element, you must do the
case drain filter element installation test.

General
The standby hydraulic system operates automatically or
manually as a backup to the hydraulic systems A and B.
The standby hydraulic system supplies hydraulic fluid under
pressure to operate these components:
* Leading edge flaps and slats
* Standby rudder power control unit.
* Left and right thrust reversers
Fluid Supply
The standby reservoir contains the hydraulic fluid supply for the
standby hydraulic EMDP.
The fill balance line connects the standby reservoir to the
