Insufficient throughput and low vibration width

Check whether the working weight is too low!

Have the spring mounting bolts been loosened? They must be tighte-

ned with a specified torque - otherwise the eigenfrequency will shift.

Is the small conveyor unit able to vibrate freely? Does it rest on rubber

feet as required? If free vibration is impeded, throughput will be impai-

red!

Ensure that channel or rail are stiff against vibration and do not reso-

nate within the small conveyor drive’s resonance band. In this case,

the drive power is absorbed by the channel/rail or the attachment

structure. In the worst case, something may break. Furthermore, other

conveyor units mounted on the same support may also be affected.

Check whether the attachment bolts for the working unit are too long!

If the bolts reach too far inside the small conveyor drive, they may

impede the free vibration of the upper part.

Ensure that the material transported does not form deposits due to its

consistency or particular environmental conditions leading to conden-

sation! Deposits lead to decreased throughput and stopper-to-stopper

operation due to the increased working weight.

Faults during operation

Noise: do tone and volume change during operation? This points at unusual

wear, which may have its cause in, e.g., a change in the working weight or

the material transported.

Check whether the small conveyor drive is overloaded due to deposits,

a change in properties of the material transported, or due to other

changes to the process. Also check the state of the connector set.

Check whether the working weight could be increased by deposits on

the transport rail or the trough. This results in stopper-to-stopper ope-

ration and eventually in a rupture of the springs.

Broken springs or bolts on leaf springs. Have the springs replaced by the

manufacturer.

Check whether the unit has operated stopper-to-stopper (see above).

Are there deposits?

ã Has the vibration width increased? The maximum value must not be

exceeded (see Table 7.3 for values).

l General failure of the small conveyor drive or the control unit

ã Check whether the environmental temperature at the time of failure

was between -25 °C and below +40 °C. The conveyor units only ope-

rate properly within that range.

l Incorrect throughput

ã Check whether the height of the funnel outlet is correct and amend it if

required: If the height is lower, the throughput decreases, if the height

of the funnel outlet is larger, the channel may overflow.
