Check with precision hoist.
Actuate the UP-button in the control pendant with caution.
Observe the hoisting movement, until the operational hoist limit switch switches off in
the top hook position (B
).
Actuate the override button (S260) in the control box and the UP-button at the same
time until the emergency hoist limit switch switches off (A
).
–
When using the optional hook operated hoist limit switch (see chapter 4.11), this
must be overridden.
–
If the wire rope hoist does not travel further, the emergency hoist limit switch has
already switched off during step 2 and the operational hoist limit switch is not
working.
Theminimum distance “a” between the hook block and the next
obstacle, see table, or
hook aperture “C”
-
“c” (see
section
Hook dimensions C for KE-S.. trolleys
) must be
maintained as a minimum, depending on the dimension at which the hook hangs
lower.
With deviations, adjust the geared limit switch again (see section
Adjusting the
geared limit switch
).
Actuate the override button (S261) in the control box and the DOWN-button at the
same time to exit the top switching area.
