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
).
Prior to reaching the switch-off point (B
), make sure that a reduction to the slow
speed takes place (B
).
The minimum distance “a” + “c” between the hook block and the next
obstacle or
hook aperture “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
.
The switching point distances between operational and emergency hoist limit switch are
aligned with normal conditions of operation and can be increased if necessary.
