3.4 Slip clutch adjustment
3.4.1 Introduction
The slip clutch on the drive unit is a safety device which allows the chain
to stop if the load becomes excessive. It has two purposes:
• Prevent damage to conveyor
• Prevent damage to the products on the conveyor
Where a slip clutch is fitted, it must be adjusted so that it does not slip
whenever the drive unit is started under full load. The installation is carried
out as follows:
Preparations for adjustment
• Stop the conveyor.
• Ensure that the conveyor can not be started accidentally. For ex-
ample: unplug the electric power plug.
• Remove any load on the conveyor.
Caution:
If you try to adjust the slip clutch when there is still load on the
conveyor, the accumulated tension in the chain can cause se-
vere injuries when you release the clutch.
Slip clutch should not be adjusted until
• Motor direction is confirmed
• Conveyor is fully assembled
Important:
The slip clutch is not a personal safety device. It is primarily intend-
ed to protect the equipment.
