Troubleshooting
DANGER
!
Before installing, servicing, or adjusting the belt cleaner, turn
off and lockout / tagout / blockout / testout all energy sources
to the conveyor and conveyor accessories according to ANSI
standards or country specific safety standards (DIN, ISO,
etc.). Failure to do so could result in serious injury or death.
Symptom
Corrective Action
Insufficient cleaning and
carry
b
ack.
Check to see that cleaner is contacting the
b
elt across the front edge
of the cleaner. Inspect
b
elt surface,
b
elt edges, and pulley lagging.
Recheck mounting dimensions and adjust as necessary. Gradually
increase tension in 5-10% increments, maintaining 15% less tension
on
b
ottom rope, until cleaning is sufficient. Ensure tensioner spring
in not totally collapsed and watch for chute flex.
Belt is cleaner on one side
than the other.
Check installation, ensure cleaner is properly mounted and make any
adjustments. Cleaner is likely out on one side and needs to
b
e
moved closer to the
b
elt, re-tension cleaner (see Figure 9).
Blade dancing or

b
ration.
Check installation, ensure cleaner is properly mounted and make
any adjustments. Cleaner is likely out on one side and needs to
b
e
moved closer to the
b
elt, re-tension cleaner as descri
b
ed a
b
ove (see
Figure 9). Check tension on tensioner gauge to
b
e sure of proper
tension. Reset tension according to tensioning charts. Ensure
b
lade
is installed at proper angle. Ensure cleaner is centered on the pulley
and excess ca
b
le on either side of
b
elt does not exceed 150 mm
(6 in.).
Ensure chute wall is not flexing. Increase support as necessary.
Cleaner is catching on
mechanical splice.
Check that outer 3–4 elements are off the
b
elt
b
y at least 3–6 mm
(1/8–1/4 in.) to allow for the splice to flow through the cleaner without
catching. Increase gap as necessary to allow splice to pass.
Material
b
uilds up in gaps.
Remove any excess material and check to ensure cleaner is
properly located. Ensure
b
ottom rope is properly positioned, adjust
b
ottom rope on
b
ottom side away from conveyor slightly
b
y rotating
b
ottom
b
racket. This will increase gap and allow material to
b
e
discharged more easily. Add more tension. Increase difference
b
etween tension on top and
b
ottom rope to 15%.
