SETTING THE SWITCHING POINTS
OF AN ELECTRONIC HOIST LIMIT
SWITCH
ONLY WITH AN ELECTRONIC
HOIST LIMIT SWITCH
The switching points of the electronic hoist limit
switch can be set without opening the chain hoist.
This requires the supplied teach-in module or a
pendant control with teach-in button, or an
ABURemote AC receiver with teach-in.
The switching points do not need to be reset if the
chain and chain sprocket are replaced. If the chain
and chain sprocket are replaced, only the reference
point needs to be reset. See “Exchanging the chain
and chain sprocket” page 45.
OVERRUNNING THE PREVIOUS
SWITCHING POINT
If the new upper or lower switching point is in an
area that cannot be approached due to the
previous switching point, the previous switching
point must first be overrun.
To overrun a switching point:
Move to the previous switching point until
the load hook stops.
─ Only with teach-in module: Remove the
pendant control, plug in the teach-in
module, wait 5 seconds, then remove the
teach-in module and insert the pendant
control.
Only with pendant control with teach-in
button: Press teach-in button for 5 seconds.
Only with ABURemote AC with teach-in:
Press “teach-in” direct access button (T with
arrow) for 5 seconds.
Raise or lower the load hook over the
previous switching point.
● The previous switching point has been
overrun.
SETTING THE UPPER SWITCHING
POINT
Overview of setting the upper switching
point:
(Described in detail below)
─ Move to the new switching point.
─ The last movement command before teach-
in must be the “Lift” button.
─ Only with teach-in module: Remove the
pendant control, plug in the teach-in
module, wait 5 seconds, then remove the
teach-in module and insert the pendant
control.
Only with pendant control with teach-in
button: Press teach-in button for 5 seconds.
Only with ABURemote AC with teach-in:
Press “teach-in” direct access button (T
with arrow) for 5 seconds.
Moving to the upper switching point:
Raise the load hook to the desired switching
point.
─ Bottom block or hook assembly must not
come into contact with the housing.
─ The friction clutch must not be triggered.
─ The new switching point must not be too
close (about 10 cm) to a previous switching
point. If it is too close, the following
sequence is interpreted as the “Overrun
previous switching point” function.
If a new switching point is to be set within
this range, a switching point further away
must first be temporarily set and only then
the switching point at the desired hook
position set.
─ The switching point cannot be above the
reference point because the load hook
cannot be moved up beyond the reference
point.
Normally, this situation should not occur
because the reference point is usually
programmed to be at the highest hook
position (bottom block or hook assembly
just below the housing) and therefore the
load hook cannot move any higher.
Finally, briefly press the “Lift” button.
Before teach-in, the “Lift” button must be
pressed last if the upper switching point is to
be set.
