3. ELECTRONIC CONTROLLER
The electronic controller interprets DEPLOY and STOW requests and controls ramp functions. It contains a pro-
grammable integrated circuit (IC), relays, two fuses, and associated parts. The programmable IC cannot be ac-
cessed externally. The ramp harness, which is connected to controller connector J1, supplies system power in ad-
dition to STOW and DEPLOY requests. Connector J1 also provides positive and negative interlock signals. Con-
nectors J2 and J3 receive signal inputs from the RAMP STOWED and RAMP DEPLOYED sensors, respectively.
Connector J4 provides directional control signals to the hydraulic pump. Connector J5 provides a timing signal to
the auxiliary counter.
Refer to Figure 3-1 for locations of J1, J2, J3, J4, and J5 connectors. The controller cover is sealed with silicone
rubber and is not easily removed. Note the four mounting holes at the corners of enclosure. Note fuse location at
top, right corner. Refer to
Table 3-3 for functions and ratings of fuses located inside controller. Access to the con-
troller is gained by removing bottom cover from ramp. Reseal the cover with silicone rubber before reinstalling.
Refer to Figure 3-3 for connector pin numbering and wire colors. Refer to Table 3-4 for a signal description of each
connector pin.
Refer to Section 4 for a description of sensor light activity during ramp movement.
