ICS TRIPLEX 9110工控模块备件
安全保护是设置点密码功能的补充，该功能独立运行（参见第4-6页第4.2.1节：密码）。b） 测试开关469投入使用后，可作为定期维护计划的一部分不时进行测试。继电器将积累与起动器和电机运行历史相关的统计信息。该信息包括：上次跳闸数据、需求数据（如果使用计量功能）、MWh和Mvarh计量、RTD最大值、事件记录、模拟输入最小值和最大值、电机跳闸次数、类型跳闸次数、电机总运行时间、学习参数、启动机操作次数、电机启动次数、紧急重启次数和数字计数器。短路469测试输入（端子C3和C4）可防止继电器测试时所有数据损坏或更新。测试端子短路时，在用LED将闪烁。c） 紧急重启短路端子D17和D23将使用的热容量放电至零，将任何启动/小时锁定设置为零，将启动之间的时间锁定设置为0，并重置所有跳闸和警报，以便热电机可以重新启动。然而，重新启动块锁定将保持激活状态（它可以用作后旋计时器），任何剩余的跳闸条件（如热RTD）仍将导致跳闸。因此，当端子短路时，跳闸和闭锁输出继电器将保持在正常非操作状态。如果发生真正的紧急情况，紧急重启端子应保持短路，直到紧急情况结束。此外，当紧急重启端子短路时，维修警报消息指示任何激活的跳闸或阻塞。顾名思义，该功能只能在紧急情况下使用，否则会破坏继电器的目的，即保护电机。任何从打开到关闭或从关闭到打开的紧急重启输入转换都会记录为事件。d） 远程重置短路端子D18和D23重置任何跳闸或锁定报警，前提是导致报警或跳闸的条件不再存在。如果有锁定时间，块启动继电器将不会复位，直到锁定时间到期。4.4.2启动器状态路径：设定值×S3数字输入启动器状态所有电机都需要该输入。当相电流低于继电器可测量的水平（CT主电流的5%）时，469确定电机已停止。监控断路器或接触器的辅助触点可防止继电器在空载电机加载时检测到额外启动，或在空载电机启动并以低于5%CT额定一次电流运行后发出闭锁启动。如果选择“起动器辅助A”，则监测端子D16和D23以检测断路器或接触器状态，断开表示断路器或触点断开，短路表示闭合。
safeguard is in addition to the setpoint passcode feature, which functions independently (see Section 4.2.1: Passcode on page 4–6). b) TEST SWITCH Once the 469 is in service, it may be tested from time to time as part of a regular maintenance schedule. The relay will have accumulated statistical information relating historically to starter and motor operation. This information includes: last trip data, demand data (if the metering features are in use), MWh and Mvarh metering, RTD maximums, the event record, analog input minimums and maximums, number of motor trips, number of trips by type, total motor running hours, learned parameters, number of starter operations, number of motor starts, number of emergency restarts, and the digital counter. Shorting the 469 Test input (terminals C3 and C4) prevents all of this data from being corrupted or updated when the relay is under test. The In Service LED will flash while the test terminals are shorted. c) EMERGENCY RESTART Shorting terminals D17 and D23 discharges the thermal capacity used to zero, sets any Starts/Hour Block lockout to zero, sets any Time Between Starts Block lockout to zero, and reset all Trips and Alarms so that a hot motor may be restarted. However, a Restart Block lockout will remain active (it may be used as a backspin timer) and any trip condition that remains (such as a hot RTD) will still cause a trip. Therefore, while the terminals are shorted, the Trip and Block output relays will remain in their normal non-operated state. In the event of a real emergency, the Emergency Restart terminals should remain shorted until the emergency is over. Also, while the Emergency Restart terminals are shorted, a Service Alarm message indicates any trips or blocks that are active. As the name implies, this feature should only be used in an emergency – using it otherwise defeats the purpose of the relay, namely, protecting the motor. Any Emergency Restart input transition from open to closed or closed to open is logged as an event. d) REMOTE RESET Shorting terminals D18 and D23 resets any trips or latched alarms provided that the condition that caused the alarm or trip is no longer present. If there is a lockout time the Block Start relay will not reset until the lockout time has expired. 4.4.2 STARTER STATUS PATH: SETPOINTS Õ× S3 DIGITAL INPUTS Õ STARTER STATUS This input is necessary for all motors. The 469 determines that a motor has stopped when the phase current falls below the level that the relay can measure (5% of CT primary). Monitoring an auxiliary contact from the breaker or contactor prevents the relay from detecting additional starts when an unloaded motor is loaded, or issuing a block start after an unloaded motor is started and running at less than 5% CT rated primary current. If "Starter Auxiliary A" is chosen, terminals D16 and D23 are monitored to detect the breaker or contactor state, open signifying the breaker or contactor is open and shorted signifying closed.
