3500系统集成了众多的自我监测功能，可以识别故障的监测模块和它们连接的传感器，识别和识别问题，通过适当的错误代码，并抑制通道操作时，故障可能危及系统的正确运作。

The 3500 system incorporates numerous self-monitoring features that identify faulty monitoring modules and the sensors to which they are connected, recognising and identifying problems by means of appropriate error codes and suppressing channel operation when faults may jeopardise the correct operation of the system.

3500系统将配置设置存储在每个模块的非易失性存储器中的两个独立位置。这种冗余允许每个模块比较配置信息以达成一致，并标记任何异常。使用冗余的非易失性存储器还可以提前对备用模块进行编程。它还确保在不使用冗余电源的情况下，当电源中断时，监控配置不会丢失。

The 3500 system stores configuration settings in two separate locations in each module's non-volatile memory. This redundancy allows each module to compare configuration information for agreement and flag any anomalies. Using redundant non-volatile memory also allows the spare module to be programmed in advance. It also ensures that the monitoring configuration is not lost when the power supply is interrupted without the use of redundant power supplies.

3500系统可以配置不同级别的冗余。范围从单一模块到双电源，再到冗余继电器模块，具有广泛和灵活的逻辑操作选项，可根据需要配置复杂的继电器逻辑。3500系统还提供各种安全完整性等级(SIL1和SIL 2)认证，用于安全仪表系统的各种3500监视器，但须经功能安全认证。

The 3500 system can be configured with different levels of redundancy. Ranging from single modules to dual power supplies to redundant relay modules with extensive and flexible logic operation options, complex relay logic can be configured as required.The 3500 system is also available with various Safety Integrity Levels (SIL1 and SIL 2) approvals for a wide range of 3500 monitors for use in Safety Instrumented Systems, subject to Functional Safety approvals.
