A5-1 DADF Interlock Open (BSD 1.7B)
Open the DADF TOP COVER and press the actuator of the
DADF INTERLOCK SW with a screwdriver.
Does the error display disappear?
YN
Close the DADF TOP COVER. Is the voltage +24 VDC
between the DADF CONT PWB J2-2(+) and GND(-)?
YN
Is the voltage +24 VDC between the DADF CONT
PWB J2-1(+) and GND(-)?
YN
Is the voltage +24 VDC between the DADF
CONT PWB J1-1(+) and GND(-)?
YN
Perform +24VDC FIP.
Replace the DADF CONT PWB. (PLXX.X)
Is the voltage +24 VDC between the DADF
INTERLOCK SW J32-1(+) and GND(-)?
YN
Check between the DADF INTERLOCK SW
J32-1 and DADF CONT PWB J2-1 for an open
wire or poor contact.
Is the voltage +24 VDC between the DADF
INTERLOCK SW J32-2(+) and GND(-)?
YN
Replace the DADF INTERLOCK SW. (PLXX.X)
Check between the DADF INTERLOCK SW J32-2
and DADF CONT PWB J2-2 for an open wire or poor
contact.
Replace the DADF CONT PWB. (PLXX.X)
Check the DADF TOP COVER actuator for damage or
misalignment.
