This manual describes the system design, function, installation, deployment, and maintenance of Quantum Hot Standby (QHS).
The document introduces the Quantum Hot Standby system, describing its hardware components such as the CHS 110 Hot Standby Module and CHS 210 Hot Standby Kit. It explains the system’s operation modes, cabling options, and the differences between 984 HSBY and IEC HSBY configurations.
Detailed chapters cover planning guidelines, step‑by‑step installation procedures, configuration using ladder logic and the CHS instruction block, Ethernet hot standby solutions, and maintenance tasks including health checks, error handling, and module replacement. Appendices provide fiber‑optic cable specifications and ProWORX Nxt configuration details.
