–
Remove the blanking plug (1).
–
Loosen the brass screw (2).
–
Insert an 8 mm, 150 mm-long Allen key into the setting
screw (3).
–
Loosen the setting screw (3).
The load limiting device must not react when lifting the load.
–
Raise until the load lifting equipment hangs freely.
Note:
If the load limiting device reacts:
–
Lower the load lifting equipment.
–
Loosen the setting screw (3).
–
Raise until the load lifting equipment hangs freely.
–
Tighten the setting screw (3) until the load limiting device
reacts.
–
Tighten the brass screw (2).
–
Lower the overload to the ground.
–
Raise the overload again.
The load limiting device must react. Otherwise repeat the
procedure.
–
Replace the blanking plugs (1) and secure with red sealing
wax.

wax.
Adjust the electric load limiting device (optional)
X-Model series:
Up to 1,000 kg load bearing capacity optional scope of
delivery
DANGER!
Danger of death due to electric shock!
–
Disconnect the power supply to the hoist by disconnect-
ing the connector before opening the terminal box.
–
Do not touch any conducting parts when performing the
adjustment.
–
Cover conducting parts if necessary.
Risk of being injured by falling objects!
Might result in severe injuries or even death!
–
The load limiting device may only be implemented by
personnel authorised by the system manufacturer or
Greifzug Hebezeugbau GmbH.
–
Observe the details in this instruction manual.
When delivered, the load limiting device has been set in such a
way that it deactivates the hoist at the latest once the load
reaches 1.25 times the load bearing capacity.
In order to set the load limiting device an overload is lifted. The
overload is:
Overload = Nominal load + 25%
The electronic load limiting device reacts to the power consump-
tion of the motor. Hoists with two speeds are equipped with two
electric load limiting devices. The adjustment must be made for
both load limiting devices and speeds. The overload is recog-
nised when lifting.
A lower limiting value, e. g. due to a lower load bearing capacity
of the components which the hoist or the deflection roller are
attached to, can only be set by authorised maintenance person-
nel.
Default setting
See Fig. 18.
–
Remove the sealing wax on the controllers (1) and (2).
–
Turn the upper controller (1) for the rated power to the right
to the limit.
–
Turn the lower controller (2) for the start monitoring to the
right to the limit.
Adjusting the overload
–
Only load load lifting equipment with the calculated overload.
–
While lifting the excessive load turn the upper controller (1)
to the left until the hoist stops.
–
Lower the excessive load until the rope is unloaded.
–
Raise the excessive load again:
The hoist must stop as soon as it comes under load.
