Dangerous movements! Danger to life, risk of injury, severe bodily harm
or material damage!
To avoid accidents, bodily harm and/or material damage:
●
For the above reasons, ensure personal safety by means of qualified and
tested higher-level monitoring devices or measures integrated in the in‐
stallation.
They have to be provided for by the user according to the specific condi‐
tions within the installation and a hazard and fault analysis. The safety
regulations applicable for the installation have to be taken into consider‐
ation. Unintended machine motion or other malfunction is possible if safety
devices are disabled, bypassed or not activated.
●
Keep free and clear of the machine's range of motion and moving parts.
Possible measures to prevent people from accidentally entering the ma‐
chine's range of motion:
–
use safety fences
–
use safety guards
–
use protective coverings
–
install light curtains or light barriers
●
Fences and coverings must be strong enough to resist maximum possible
momentum.
●
Mount the emergency stop switch in the immediate reach of the operator.
Verify that the emergency stop works before commissioning. Do not op‐
erate the device if the emergency stop switch is not working.
●
Isolate the drive power connection by means of an emergency stop circuit
or use a safety related starting lockout to prevent unintentional start.
●
Make sure that the drives are brought to a safe standstill before accessing
or entering the danger zone.
●
Additionally secure vertical axes against falling or dropping after switching
off the motor power by, for example:
–
mechanically securing the vertical axes,
–
adding an external braking/arrester/clamping mechanism or
–
ensuring sufficient equilibration of the vertical axes.
The standard equipment motor brake or an external brake controlled by
the drive controller are not sufficient to guarantee personal safety!
●
Disconnect electrical power to the equipment using a master switch and
secure the switch against reconnection for:
–
maintenance and repair work
–
cleaning of equipment
–
long periods of discontinued equipment use
●
Prevent the operation of high-frequency, remote control and radio equip‐
ment near electronics circuits and supply leads. If the use of such devices
cannot be avoided, verify the system and the installation for possible mal‐
functions in all possible positions of normal use before initial commission‐
ing. If necessary, perform a special electromagnetic compatibility (EMC)
test on the installation.
