Adjusting the geared limit switch
•
With rope drums carrying ropes, the switching points are preset in the factory.
•
If ropes are delivered loose, the switching points must be set.
WARNING
Danger due to electrical voltage.
The hood must be removed from the geared limit switch to adjust the switching points.
This exposes the live contact connections. Touching live parts can cause severe injuries
or death.
➢
Ensure that a competent person adjusts the switching points.
WARNING
Danger of personal injuries.
Incorrectly set hoist limit switches can lead to serious accidents.
➢
Check the operational hoist limit switch daily to ensure its function and correct setting.
WARNING
Danger due to falling load!
➢
Perform all checks and settings without load only.
➢
Cordon off and secure the danger zone.
NOTICE
Danger of material damage.
Never remove dust accumulations with the enclosure open using compressed air,
because the dust can significantly penetrate the contacts as a result of this and impair
the switching capacity.
Never use benzine or other solvents to clean the hoist limit switch!
➢
Observe for information on the sticker, which is applied to the inside of the hood of
the geared limit switch.
Setting options:
•
Adjust the individual switching points
“S1”
to
“S6”
.
–
Each switching point is approached and set.
•
Adjust via the block adjustment
“S0”
.
–
Using the black adjustment screw
“S0”
it is possible to perform upward and
downward block adjustment of all switching points. The relative setting of the
individual switching points to each other remains unaffected here.
