4.1
Manufacturer of the machine
DANGER
Failure to comply with manufacturer’s obligations
Hazard due to lack of effectiveness of the protective device
b
Carry out a risk assessment before using the safety locking device.
b
Do not tamper with, open, or modify the components of the safety locking device.
b
Make sure that the safety locking device is only repaired by the manufacturer or by
someone authorized by the manufacturer. Improper repair can lead to a loss of the
protective function.
b
Make sure that switch-on commands which bring about a dangerous state of the
machine are not enabled until the protective device is closed and the lock is acti‐
vated.
b
Make sure that the lock is not deactivated until the dangerous state of the
machine has stopped.
b
Make sure that closing a protective device and activating the lock does not cause
a dangerous machine function to start by itself. This must be controlled by a sepa‐
rate start command.
b
The safety locking device must not be bypassed (contacts jumpered), turned away,
removed, or rendered ineffective in any other way. Take measures to reduce
bypassing options as necessary.
The safety locking device is designed in such a way as to eliminate internal faults
according to ISO 13849–2, Table A4.
Observe EN ISO 14119 on the use of interlocking devices in conjunction with physical
guards.
4.2
Operator of the machine
DANGER
Failure to observe operator obligations
Hazard due to lack of effectiveness of the protective device
b
Changes to the machine and changes to the mechanical mounting of the safety
locking device necessitate a new risk assessment. The results of this risk assess‐
ment may require the operator of the machine to meet a manufacturer’s obliga‐
tions.
b
Apart from the procedures described in this document, the components of the
safety locking device must not be opened or modified.
b
Do not carry out any repair work on components. Improper repair of the safety
locking device can lead to a loss of the protective function.
b
Make sure that replacement actuators are not used for bypassing. Restrict access
to actuators.
