5.1
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 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.
If several devices are switched in succession and the simplified process according to
ISO 13849 is used to determine the performance level (PL), the PL may be reduced.
A logical series connection of safe contacts may be possible up to PL d under certain
circumstances. For more detailed information, see ISO TR 24119.
The safety locking device is designed so that internal errors according to ISO 13849-2,
Table A4, can be ruled out.
Observe EN ISO 14119 for using interlocking devices associated with physical guards.
5.1.1
Application of the safety locking device for process protection
At least one safe contact must be used for door monitoring.
Contacts for locking device monitoring can also be used (pin assignment
).
