Dangerous movements!
Danger to life, risk of serious injury or damage to equipment!
Preventing accidents, injury, and/or damage to equipment:
DANGER
Ensure personal safety, either by means of monitoring devices or by superior measures directly
on the system.
The measures depend on the specific system conditions and are determined based on a risk and
error analysis. The safety regulations applicable to the system must be taken into consideration.
Unintended machine movements or other malfunctions may occur when the safety equipment is
switched off, bypassed, or not activated.
Do not enter the machine's and machine parts' area of travel. Possible measures to prevent unin-
tended entry of persons include:
– Protective barriers
– Protective enclosures
– Protective covers
– Photocells
Barriers and covers must be rigid enough to withstand the maximum possible momentum.
The emergency OFF switch must be easily accessible in the immediate vicinity. Check the func-
tion of the emergency OFF system before commissioning. If the emergency OFF switch malfunc-
tions, do not operate the device.
Protection against unintended start-up by means of an emergency OFF circuit.
Safely bring the drives to a standstill before accessing or entering the danger zone.
Additionally secure vertical axes from falling or dropping after the motor is switched off by:
– Mechanical lock on the vertical axis
– External braking/catching/clamping device
– Sufficient weight compensation of the axis
Switch electrical equipment to a de-energized state at the mains and protect it against being
switched on again during:
– Maintenance and repair
– Cleaning
– Long disruptions in operation
Avoid operating high-frequency, remote-controlled, or radio devices in the vicinity of the device
electronics and cables. If this cannot be avoided, check the device and the system for malfunc-
tions in all working positions. In some cases, a special EMC inspection of the entire system may
be necessary.
In the following cases, install a torque support at the ErgoSpin hand-held nutrunner:
– ESM as of 10 Nm
– ESA or ESV as of 40 Nm
Use a torque support if tightenings with higher torques are to be performed with a hand-held
tightening spindle.
