WARNING
Danger of unintentional movement of hoist
If the rocker switch is no longer depressed by the operator, it returns to the 0 position, the
hoist motion is automatically stopped (dead man’s control).
If the hoist malfunctions, e.g. the actual motion does not correspond to the motion
intended in activating the rocker switch, release the rocker switch immediately. If the
motion continues, press the emergency stop.
If this also fails to bring the hoist to a standstill, the emergency stop switch (mains
connection switch) should be immediately switched off and secured to prevent re-
activation.

Emergency stop
WARNING
Safety hazard.
After an emergency stop, the operator must not restart the hoist /crane
system until a qualified person has determined that the fault which led to this function
being activated has been eliminated and no danger can arise from the continued
operation of the system.
Every hoist must have a means of disconnecting the power supply to all drives under load
from the ground.
