Restart after replacing a safety module
7.2.1
Replacing a safety module
If replacing a module, proceed as described for assembly and removal (see "Assembly,
removal, and electrical installation" on page 4-1).
Ensure that the new safety module is mounted at the correct position in the local bus. The
new module must meet the following requirements:
– Same device type
– Same or later version
Carry out a validation and perform a function test after replacing the module.
7.2.2
Restart
Once the safety module has been replaced, proceed as described for initial startup
(see "Initial startup" on page 7-1).
Plug the VersaPoint connectors into the correct connections.
Carry out a validation and perform a function test after replacing the module
7.3
Validation
Carry out a safety validation every time you make a safety-related modification to the
VersaSafe system.
When validating your EUC, check the assignment of the individual actuator connections.
Determine whether:
– The correct safe actuators are connected to the safety module
– The safety module has been parameterized correctly
– The signals used in your safety logic have been linked to the safe actuators correctly
Perform a function test and error simulation.
Please follow the checklist "Validation" on page B-11 during validation.
WARNING: Unintentional machine startup
Do not assemble or remove the module while the power is connected.
Before assembling or removing the module, disconnect the power to the module and the
entire VersaPoint station and ensure that it cannot be switched on again.
Make sure the entire station is reassembled before switching the power back on.
Observe the diagnostic indicators and any diagnostic messages.
The system may only be started provided neither the station nor the system poses a
hazard.
