Adjusting emergency hoist limit switching, “top” (A
)
The “top” operational hoist limit switching position must be set.
Actuate the UP-button in the control pendant with caution.
Observe the hoisting movement, until operational hoist limit switching (B
) switches
off in the top hook position.
Actuate the override button (S260) in the control box and the UP-button at the same
time, until 0.39 in before the switch-off point (A
).
–
When using the option hook operated hoist limit switch (see section 4.12), this
must be overridden (keep the connecting rope under tension).
–
Observe the minimum distance “a” between the hook block and the next obstacle,
see table, or hook aperture “C”
-
“c” (see
section 7.15), depending on the
dimension at which the hook hangs lower.
–
If the emergency hoist limit switch should switch off beforehand, turn the
adjustment screw “S1”
clockwise 1 revolution and repeat step 4.
Turn the adjustment screw “S1”
anticlockwise until the switch contact latches audibly.
Actuate the override button (S261) in the control box and the DOWN-button at the
same time to exit the switching area.
–
The “top” emergency hoist limit switching position has been set.
