GE DS200DCFBG1B可控硅模块
如果控制电源不存在时需要报警，表明监控不可用，则通过S3：输出继电器\报警继电器\报警操作设置点为报警继电器选择失败-安全操作。NC/COM触点常开，报警时变为闭合状态。如果在设定点S3：输出继电器\报警继电器\报警激活的情况下选择了未锁定模式，则报警条件消失时，报警继电器自动复位。对于LATCHED（锁止）模式，必须按下该键（或接收到串行端口重置命令）以重置报警继电器。有关所有显示的报警信息，请参阅第21页第5.3.1节：报警辅助继电器1、2、3（可选）（端子34至42）：可为第21页第5.3.1节：报警中列出的大多数报警配置附加输出继电器。当报警功能分配给辅助继电器时，它充当控制功能。
If an alarm is required when control power is not present, indicating that monitoring is not available, select FAIL-SAFE operation for the alarm relay through the S3: OUTPUT RELAYS \ ALARM RELAY \ ALARM OPERATION setpoint. The NC/COM contacts are normally open going to a closed state on an alarm. If UNLATCHED mode is selected with setpoint S3: OUTPUT RELAYS \ ALARM RELAY \ ALARM ACTIVATION, the alarm relay automatically resets when the alarm condition disappears. For LATCHED mode, the key must be pressed (or serial port reset command received) to reset the alarm relay. Refer to Section 5.3.1: Alarms on page –21 for all the displayed alarm messages. • AUXILIARY RELAYS 1,2,3 (OPTION) (Terminals 34 to 42): Additional output relays can be configured for most of the alarms listed in Section 5.3.1: Alarms on page –21. When an alarm feature is assigned to an auxiliary relay, it acts as a control feature.
