The SPS No Response alarm on the QUICK LOAD SERVO S3 occurs due to a communication problem between the remote control station and the LNS PLC. To fix this error:

1. Check the connectors between the PLC and the remote control station inside the cross piece to ensure they are correctly attached.
2. Verify continuity between the PLC and the remote control station.

These steps help restore proper communication and resolve the error.
