ATTENTION: Failure to comply with obligations of manufacturer.
Hazard due to lack of effectiveness of the protective device.
• Conduct a risk assessment before using the safety switch.
• Do not tamper with, open, or modify the components of the safety switch.
• Do not repair defective devices – they must be replaced instead.
• Make sure that switch-on commands, which bring about a dangerous state of
the machine, are not enabled until the protective device is closed.
• Make sure that a stop command is triggered when the protective device is
opened during the dangerous machine state.
• The safety switches must not be defeated (that is, contacts jumpered), rotated
away, removed, or rendered ineffective in any other way. If necessary, put
measures in place to reduce possibilities for defeat.
ATTENTION: Failure to comply with obligations of the operating entity.
Hazard due to lack of effectiveness of the protective device.
• Modifications to the machine and modifications to the mechanical mounting of
the safety switch necessitate a new risk assessment. The results of this risk
assessment may require the operating entity of the machine to fulfill the
obligations of the manufacturer.
• Apart from during the procedures described in this document, the components
of the safety switch must not be opened or modified.
• Do not perform repair work on the components. Improper repair of the safety
switch can lead to a loss of the protective function.
• Verify that there is no bypassing by replacement actuators. Restrict access to
actuators.
