This safety manual describes the Pluto Safety PLC, a system for controlling safety functions. It details hardware requirements, programming guidelines, personnel qualifications, and testing procedures. It also includes status messages, user fault codes, I/O fault codes, CPU fault codes, and AS-i fault codes. Key technical specifications such as electrical ratings, environmental conditions, I/O types, and response times are provided. The system is designed according to the 'de-energisation' principle, ensuring a safe state (stop/off) upon 0V, open circuit, logic '0', or low signal. It is crucial that personnel involved have sufficient knowledge of the system and machinery safety.
