7.2 Restart after replacing a safety module
7.2.1 Replacing a safety module
If replacing a module, proceed as described for mounting and removal (see Section “Mount-
ing, removal, and electrical installation” on page 39).
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
7.2.2 Restart
Once the safety module has been replaced, proceed as described for initial startup (see
Section “Initial startup” on page 65).
The parameterization of the previous module remains the same and is transmitted to the
new module when the system is started.
Plug the Inline plugs into the correct connections.
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
INTERBUS-Safety, SafetyBridge or PROFIsafe system.
When validating your individual EUC, check the assignment of the actuator connections.
Determine whether:
– The correct safe actuators are connected to the safety module.
– The safety module has been parameterized correctly.
– The variables used in your application program have been linked to the safe actuators
correctly.
Please observe the checklist “Validation” on page 104 during validation.
WARNING: Unintentional machine startup
Do not mount or remove the module while the power is connected.
Before mounting or removing the module, disconnect the power to the module and the
entire Inline station and ensure that it cannot be switched on again.
Make sure the entire system is reassembled before switching the power back on.
Observe the diagnostics indicators and any diagnostic messages.
The system must only be started when neither the station nor the system can cause any
damage.
