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 products on conveyor
•
Prevent damage to conveyor
Note
The slip clutch is not a personal safety device. It is prima-
rily intended to protect the equipment.
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
1 Stop the conveyor.
2 Ensure that the conveyor cannot be started acciden-
tally. For example: unplug the electric power plug.
3 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 severe injuries when you release the clutch.
Adjustment procedure (see Figure 1)
1 Remove the drive unit protection cover.
2 Use an Allen key, 3 mm, to loosen the screw (1) on the
slip clutch so that the adjustment nut (2) can be freely
rotated.
3 Turn the adjustment nut (2) clockwise with a hook
spanner (see Figure 2) until the arrow on the nut is
aligned with the desired Fmax value (3). See Table 1
for correct values.
Note: On delivery, the clutch is always set to “0”.
4 Tighten the screw (1).
5 Re-install the drive unit protection cover.
