Additional customized testing through FM: Honeywell engineers collaborate with FM to develop specialized simulation tests for scenarios not covered by FM standards such as “partial occlusion” and “fog/mist” to further validate product performance.
Advantages of open circuit gas detection technology (compared to point type detectors)
As a supplementary solution to point detectors, open circuit detectors have the following irreplaceable advantages:
The reliability of the detection has been verified through practical applications, reducing the risk of missed detections (for example, point detectors may miss pipeline leaks, while open circuit detectors can accurately capture them)
Covering a wider area makes it easier to detect leakage points at any location
The response speed is much higher than that of point detectors
Fault safety design: No unexposed fault modes, no problem of detector gas path blockage
The installation position requirements for detectors are lower, and there is no need to strictly align with potential leakage points
Easy installation and debugging, can replace multiple point detectors, and reduce overall deployment costs

Responsibility statement: If the device is used in a manner that does not comply with the manufacturer’s regulations, the protective function of the device may become ineffective; Rockwell is not responsible for indirect/consequential damages, and the examples in the manual are for illustration only and do not represent actual application guarantees.
System core features and authentication
1. Core functions and security design
Application scenarios: Suitable for safety critical scenarios such as emergency shutdown (ESD), fire and gas detection, rotating machinery control, burner management, etc., while supporting non safety but business critical control requirements.
Security Capability:
Both fail safe and fault tolerant architectures are supported, and fault tolerance can be realized through two module (1oo2D) or three module (2oo3D) configurations.
Built in comprehensive diagnostic function, capable of detecting hardware/software faults. The faulty module needs to be replaced within the mean time to repair (MTTR) to avoid a decrease in SIL level.
Supports two configurations: “Power Loss Trip (DTT)” and “Power On Action (ETA)”, and the number of modules needs to be selected based on SIL level and demand rate (high/low) (see Table 1).
2. Module configuration and SIL compliance requirements
Minimum module configuration for different application scenarios (simplified version of Table 1):
Application type, number of input modules, number of processor modules, number of output modules
SIL 2/3， Low/high demand, DTT 1 2 1
SIL 2， High demand, ETA 2 2 2
SIL 3， High demand, ETA 2 2 2

Safety lifecycle and management system
1. Safety lifecycle stages
The full lifecycle defined by IEC 61508 must be followed, with core stages including:
Scope definition: Clearly define system boundaries, interfaces (with processes/third-party equipment), and environmental requirements (such as temperature and power).
Hazard and Risk Analysis: Identify hazardous events, trigger sequences, and risk levels as inputs for safety requirements.
System Design and Engineering: Divide system architecture, define security requirement levels for each component, and refine hardware/software design.
Integration and Verification: The application is integrated with the controller to test and verify whether SIF meets SIL requirements (such as response time and fault handling).
Operation and Maintenance: Develop an operation/maintenance plan to ensure the SIL level is maintained during operation; Changes must be strictly controlled, and suspensions must follow safety procedures.
2. Requirements for Safety Management System
Policy and Planning: Functional safety policies need to be developed to clarify measures, responsibilities, and record management (including change control) for each stage of the lifecycle.
Personnel capability: Personnel qualifications need to be evaluated, including engineering experience, functional safety knowledge, regulatory familiarity, etc. Higher qualification requirements are required for high-risk scenarios.
Functional Safety Assessment (FSA): Led by senior personnel independent of the project, it reviews whether the entire lifecycle work meets the requirements.
System Architecture Design (SIL 2/3)
1. SIL 2 architecture
Fault safety architecture: single input (1oo1D), dual processor (1oo1D degraded), single output (1oo1D), triggering a safe state in case of a fault.
Fault tolerant input architecture: dual/triple input (1oo2D/2oo3D), dual processors, single output. When a single input module fails, it will operate in a degraded state while still maintaining safety functions.
High demand architecture: dual input, dual processor, dual output, ensuring that faulty modules are replaced within MTTR to avoid SIF shutdown.
2. SIL 3 architecture
Fault safe I/O+fault-tolerant processor: single input/output, dual/triple processor (1oo2D/2oo3D), downgraded in case of processor failure, dual fault triggers safe state.
Fault tolerant I/O architecture: dual input/output, dual processors, both input/output modules support 1oo2D degradation, suitable for high safety requirements scenarios.
TMR architecture: three inputs, three processors (2oo3D), dual outputs, with the strongest fault tolerance. A single module failure does not affect system operation. When there are two failures, it will be downgraded, and when there are three failures, it will trigger a safe state.
3. Secure network communication
SNCP protocol: SIL 3 certified “Black Channel” protocol, supports Ethernet transmission of secure data, achieves data exchange between controllers through “variable binding”, and can be configured as single network (fail safe) or dual network (fault-tolerant).
Peer to Peer communication: Supports SIL 3 data transmission between AADdistance and Trusted controllers, based on master-slave mode, and recommends using redundant networks to ensure availability.
Installation and environmental requirements
1. Non hazardous environment
Environmental conditions: temperature -25 ° C~+60 ° C, pollution level ≤ 2 (IEC 60664-1, only non-conductive pollution, occasional condensation); The burner management application requires an enclosure protection level of IP40 (indoor)/IP54 (outdoor).
Installation requirements: The module should be installed vertically (ensuring natural heat dissipation), DIN rail or wall mounted, without the need for forced air cooling.
2. Hazardous environment
Special requirements:
The enclosure protection level is ≥ IP54 (IEC 60079-0/7) and must be marked with “Do not open when powered on”.
Grounding wire cross-sectional area ≥ 3.31mm ², wire temperature rating ≥ 85 ° C, only supports vertical installation.
The temperature range is the same as non hazardous environments, and the pollution level is ≤ 2.
Operations and Security Assurance
1. Key daily maintenance items
Fault handling: When the processor/input/output module fails, it needs to be replaced within MTTR; If not replaced in a timely manner, the relevant SIF needs to be shut down (unless there are compensatory measures in the SRS document).
Calibration and testing: Regularly calibrate sensors/actuators, test SIF response time (≤ 1/2 of process safety time PST), and archive test records.
Backup and Update: Regularly backup system configuration (AADvance Workbench/SIS Workstation project) and test backup effectiveness; Firmware updates require the use of the ControlFLASH tool.
2. System security measures
Network security: it is forbidden to connect to the unprotected Internet; Computers need to have firewalls, antivirus software, and password protection enabled; The software license USB key needs to be properly kept.
Port security: Some Ethernet ports (such as TCP 1132, UDP 2010) are open by default, and unused ports need to be closed through a firewall (refer to the configuration guide).
Program Security: The application requires password protection, and the controller needs to insert the “Program Enable Key” to modify the configuration; It is prohibited to force I/O points during operation, and it is recommended to use the program’s “override” logic for maintenance.

Core functions and standard configurations
（1） Three standard configuration schemes
RED615 provides three predefined configurations that cover different ground fault protection requirements, with the following core differences:
Configuration Type Core Protection Function Applicable Scenarios Key Modules
Configure A (line differential protection), including line differential protection (87L), three-phase overcurrent protection (50P/51P), negative sequence overcurrent protection (46), and circuit breaker failure protection (51BF), for cable feeders. In scenarios where ground fault protection is not required, there is no zero sequence voltage input and the CT synthesis of zero sequence current is relied upon
Configuration B (including directional grounding fault protection) Configuration A: All functions+directional grounding fault protection (67N), transient/intermittent grounding fault protection (67NIEF), automatic reclosing (79). For overhead lines/cable mixed lines, it is necessary to distinguish the fault direction of the power grid (such as multi power distribution network), including zero sequence voltage input (U ₀), and adapt to the compensation grounding system
Configuration C (including non directional grounding fault protection) Configuration A: All functions+non directional grounding fault protection (50N/51N), automatic reclosing (79), radiation type distribution network, no need to distinguish fault direction scenarios (such as single power supply feeders) rely on CT synthesized zero sequence current, no zero sequence voltage input
（2） Detailed explanation of key protection functions
Line differential protection (LNPLDF1, 87L)
Core function: As the main protection, it realizes unit protection of the line and quickly cuts off internal faults;
Features: Contains stable low order (can be locked by CT fault detection) and instantaneous high order (can dynamically adjust the action value through remote circuit breaker status);
Communication dependency: It is necessary to establish protective communication with the remote IED, which will automatically lock in case of communication failure to avoid misoperation.
Earth fault protection
Directional (configuration B): Based on the phase of zero sequence current (I ₀) and zero sequence voltage (U ₀), the fault direction is determined, suitable for multi terminal power grids, divided into low order (sensitive section) and high order (fast section);
Non directional (configuration C): Based solely on zero sequence current amplitude action, suitable for single ended power grids, divided into low order, high-order, and instantaneous order.
Starting condition: triggered by protection action signals (such as overcurrent, ground fault);
Locking logic: The circuit breaker spring is not storing energy, the gas pressure is low, and it is locked when manually opening;
Status indication: LED5 is lit during the reclosing process, and an alarm is triggered when it fails.
Circuit breaker related protection and monitoring
Circuit breaker failure protection (CCBRBRF1, 51BF/51NBF): When the circuit breaker is not opened after the protection action, a trip command is sent to the upstream circuit breaker;
Trip Circuit Monitoring (TCSSCBR1/2, TCM): Monitor 2 sets of trip coil circuits, and lock the monitoring function when the circuit breaker is opened;
Circuit breaker status monitoring (SSCBR1, CBCM): Based on current and contact status, the mechanical characteristics of the circuit breaker are determined, and an alarm is triggered when there is an abnormality.
IEC 60870-5-103 Protection signal upload, telemetry and remote signaling RS-485 or Ethernet
Modbus RTU/ASCII third-party device interconnection (such as PLC, SCADA) RS-485 or RS-232
DNP3 telemetry, remote signaling, remote control, supporting TCP/IP or serial Ethernet or RS-485
（2） Precautions for Communication Networking
GOOSE application: supports the highest performance level (transmission delay ≤ 3ms), meets the tripping requirements of distribution substations, and can simultaneously send events to 5 clients;
Client limitation: A single IED can support up to 5 concurrent clients. After PCM600 occupies 1, the remaining 4 can be allocated to other protocol clients;
Time synchronization: Line differential protection requires remote station time reference synchronization, which is recommended to be implemented through IEC 61850 or SNTP.
PPU-3 is a compact microprocessor control unit launched by DEIF, which integrates the protection and control functions of synchronous/asynchronous generators in an “integrated” design. It has a built-in galvanized separated three-phase measurement circuit and is designed for ship application scenarios. It supports two core working modes (which can be combined):
Stand alone operation: independent power supply control for a single generator;
Parallel with other generators: Multiple generators are synchronized in parallel to achieve load distribution and coordinated control.
Its core value lies in simplifying the generator control chain, which can be connected to the PLC control system through digital/analog I/O or serial communication, and has flexible functional expansion capabilities.
