Replacing the device

WARNING

The safety option does not detect that the encoder was replaced and still shows the replaced encoder as referenced.
Severe or fatal injuries.
- Ensure that the safety option delivers the same raw value at the same system position after replacing the encoder or perform a new referencing.
- Carry out a functional test.
The "Device marked as removed" feature does not become invalid in the following cases:
- The device with safety option has been replaced
- A sensor or actuator connected to the safety option has been replaced
The safety option is not capable of recognizing these cases. Both the "RUN" LED and the standard process data continue to signal the "Assembly accepted" status. In these cases, it is the user's responsibility to check to what extent a new acceptance is required.
Replacing a device with MOVISAFE® CSA31A safety option
When replacing a device with CSA31A safety option, incrementally evaluated encoders must be referenced again.
When replacing a device with CSA31A safety option with a device with new CSA31A safety option without saved referencing data, the referencing is preserved on encoders that are not only incrementally evaluated if the safety key from the previously used safety option continues to be used.
If a CSA31A replacement safety option that already has referencing data saved is used, the referencing data from the safety key is not automatically accepted. The referencing can be taken from the safety key during the next system start via MOVISUITE® using the [Accept referencing] button. Once the button is actuated, the safety option must be restarted. As an alternative, a new referencing can be performed.
