Troubleshooting:
Fault
Poor capacity
Conveying stopped
but blower continues
to operate
8
Cause
Feed not correctly adjusted.
Piping incorrectly installed.
Rotation direction of blower (or
rotary valve) incorrect.
Material being blown into contai-
ner with inadequate air outlet.
Worn seals in rotary valve.
V-belts are too slack or possibly
worn out.
Intake regulator shutter cannot
move freely.
The rotary valve / venturi does
not match the blower.
Rotary valve / venturi is pointing
in wrong direction
Pipe blockage.
Rotary valve rotor blocked by
impurities in the material
Remedy
See section "Start".
See section "Pneumatic conveying".
Change direction of rotation. Correct direction is shown
in section "Electrical installation".
Open container to allow air to escape.
Replace seals.
Tighten or replace the V-belts. See section "Service
and maintenance".
The shutter is not released from start position, or the
function of the shutter is impeded by impurities, and ne-
eds to be cleaned.
Use the correct feed. See section "Conveying capa-
city".
Reverse the feed – see arrow on rotary valve / venturi
Close the intake shutter at the rotary valve, and see
whether the blower itself is able to clear the piping. If
this is not possible, the piping must be dismantled and
emptied.
Remove impurities, and check whether rotor has been
damaged
