Troubleshooting
Poor capacity/stop
All the machines in the conveyor system must be correctly adapted to each
other in order to provide the correct capacity for the given conditions.
Problems with capacity and stops can arise for different reasons:
General
Check:
• that capacity demands are realistic for the conditions in question. Capacity
will be reduced if the water content in the grain is increased/raised. Reckon
on a loss of capacity in the range 3-4% for every 1% water content above
15%. Especially installations with short trenches (2.5-4.5 m) will have
problems if the water content is high.
• that connections between machines are carried out correctly. See the
assembly instructions for respective machine.
• that the inlet is correctly assembled. See the assembly instructions for
respective machine.
• that the ducting is sufficiently dimensioned. Ø160 mm for 30 t/h, Ø200
mm for 40 and 60 t/h, Ø250 mm for 80 and 100 t/h and Ø300 mm for
120 and 150 t/h.
• that the ducting is sufficiently inclined, greater than 45°.
• that the machines and connections are free from waste.
• that the machines work at the correct speed in relation to the intended
capacity. See the section "Technical specifications".
• that the electrician has connected the motors to the correct voltage and
that the motor protection is set to the right values.
• that the machine feed rate is not too high. See the section "Technical
specifications".
If the elevator is first in a chain of conveyors, fit and use inlet slide. See
assembly instructions for the elevator. NB! An ammeter on the elevator
leg by the slide regulator simplifies setting the inlet slide to the desired
capacity.
!
IMPORTANT!
If an operation stoppage is due to overfeeding, the elevator boot must be
cleared of grain before the elevator can be restarted.
• that the bucket belt is tensioned correctly. See the maintenance
instructions.
• that the inlet slide mounted on the ascending leg side can be opened fully.
See assembly instructions for the elevator.
• that the elevator boot is free from grain from previous seasons. It may start
to grow and hinder the input feeding.
• that the connecting channel and the elevator inlet for an elevator mounted
in an elevator trench are the same size and that the angle of inclination is
at least 45°.
