8. If the rotary limit switch stopped the drive unit in step 6 then the checkout of the limit switch is
complete.
9. If the limit switch cam has not quite activated at this point, continue to lower the DLS until the
cam actuates the lower level switch.
10. If this point occurs within 1-1/2 inches of the published extension height on the customer certified
drawing and the lift cables are still in tension, no further adjustment is necessary.
11. Raise and lower the spout several times to ensure it is performing properly and stopping at its
upper and lower rotary limit switch set points.
12. If the lift cables are slack or the extended position is lower than desired, the switch point must be
reset.
6.8 INTERNAL CONE INSPECTION AND REPLACEMENT
Internal cones should be inspected to ensure that product flow into the vehicle/container, or air flow up
through the spout, is not restricted due to damaged components. If bent, damaged, or worn components
are discovered, these components can be easily and economically replaced.
Special attention should be paid when loading hydroscopic or sticky material through loading spout.
Periodically check internal cones for product build-up; if build-up is found, strike or scrape each cone to
eliminate it.
6.8.1 Intermediate Cone Replacement/Inspection (Lower Half)
!!! WARNING !!!
Prior to performing cone inspection or
replacement, the system must be
isolated from all external power
sources. If work is being done on the
cone assembly and the drive motor
engages, it could result in personal
injury or death.
1. With the unit in its full
extended position, loosen the
bolts on the lower end of the
dust sleeve.
2. Raise the sleeve up as far as
necessary to inspect the lower
cones. Secure the sleeve in a
raised position by tying it off or
other appropriate means.
3. To replace a cone, disconnect
the U-bolt cable clamps from
the cone (
) and remove the cone. Leave the clamps attached to the cables.
